Live updates: Rare severe storm outbreak targets East Coast, historic blizzard paralyzes the Midwest

Nearly 40 million Americans are on high alert this afternoon as the monster March storm takes aim at the nation’s most densely populated corridors.

Tornado Watches now cover most of the I-95 corridor from New Jersey to Florida.

A Tornado Watch is now in effect for parts of North Florida and extreme Southeast Georgia until 8:00 p.m. ET.

As a powerful cold front charges east, it is pushing a line of intense thunderstorms across the Gulf Coast, bringing the threat of tornadoes, damaging wind gusts up to 60 mph, and isolated hail.

The watch currently covers several northern counties—including the Jacksonville metroand Gainesville—through early evening.

Behind this front, temperatures are expected to plummet, with a hard freeze possible for inland areas by Tuesday morning.

When a severe storm tears through a neighborhood, the immediate question is almost always, “Was it a tornado?” While tornadoes are the most famous face of severe weather, National Weather Service survey teams often find that the culprit was actually a powerful downburst or straight-line winds.

The easiest way to tell the difference is to look at the debris: a tornado acts like an inhaler, sucking air inward and spinning it, which leaves a chaotic, circular mess where trees may be pointing in several different directions.

In contrast, straight-line winds act like an exhaler, occurring when rain-cooled air crashes to the ground and spreads out, mowing down trees in parallel rows like a box of spilled toothpicks.

It is a common myth that a “twisted” tree trunk proves a tornado occurred. In reality, because trees are naturally asymmetrical, a blast of straight-line wind hitting one side of a canopy more than the other can cause the trunk to twist and snap even without a rotating funnel.

Don’t let the lack of a twister label fool you, though; straight-line winds can easily exceed 100 mph, matching the power of an EF-1 tornado. And straight-line winds can be more widespread than the damage from a single tornado.

FOX weather meteorologists say the survival strategy remains identical: get to the lowest floor of a sturdy building, stay away from windows, and protect your head.

Spring break is off to a chaotic start for thousands of travelers as the monster March storm continues its destructive path across the United States.

According to the latest FlightAware data, the total number of flight disruptions for the Sunday-through-Tuesday period has now surged past 24,000. The staggering breakdown of the meltdown includes over 17,200 delayed flights and more than 6,960 cancellations.

What began as a historic blizzard in the Midwest—burying hubs like Minneapolis-St. Paul (MSP) and Chicago O’Hare (ORD) in record snow—has now evolved into a high-impact severe weather event for the East Coast.

Ground stops and delays have been rolling through major gateways like Atlanta (ATL), Charlotte (CLT), and Dulles (IAD) all day, while high winds are currently clobbering the Philadelphia and New York regions.

With 6,900+ flights completely removed from the schedule and airlines already operating at near-capacity for spring break, the ripple effect of these disruptions is expected to last well into the weekend.

Travelers are being urged to download their airline’s app for the fastest rebooking options, as wait times for phone support have reportedly climbed to over four hours for several major carriers.

The main event of today’s Level 4 severe weather outbreak is fast approaching the I-95 corridor. While we have seen scattered storms throughout the morning, the primary squall line is expected to tap into peak daytime heating this afternoon, turning into a high-speed wall of wind as it moves toward the coast.

The critical windows

Because these storms will be moving northeast at a staggering 60 mph, your window to react will be small. Here is the estimated timing for the arrival of the most dangerous wind and tornado threats:

Washington, D.C. & Northern VA: 3:00 p.m. – 6:00 p.m. ETBaltimore & Central Maryland: 4:00 p.m. – 7:00 p.m. ETPhiladelphia & Harrisburg, PA: 5:00 p.m. – 8:00 p.m. ETNew Jersey & New York City: 7:00 p.m. – 10:00 p.m. ETDelaware & Eastern Shore: 6:00 p.m. – 9:00 p.m. ET

Evening commute impact

The most intense weather is timed almost perfectly to hit during the evening commute.

Local officials in Maryland and Virginia have already dismissed many schools early to avoid having buses on the road during the peak of the 80-mph wind threat.

If you are in the I-95 corridor, you should aim to be at your safe destination before 4:00 p.m. ET.

Herman, Michigan, has reported a staggering 36.0 inches of total snow over the last 48 hours, it’s the pace of the storm that has climatologists buzzing: 34.0 inches of that snow fell within a single 24-hour window.

To put this in perspective, Michigan’s current official 24-hour snow record is 32.0 inches, set in this very same town of Herman back in December 1985 (though some unofficial reports of 30 inches from 1996 often cite the same area).

If the National Weather Service verifies this 34-inch report, it will officially become the greatest one-day snow in Michigan’s history.

For the residents of Baraga County, this isn’t just a statistic—it’s a total emergency. With nearly three feet of snow falling in a day, combined with 50-mph winds, the Upper Peninsula is facing impossible travel conditions as drifts likely bury entire vehicles and first-floor windows.

A historic blizzard is slamming the Midwest with millions in the threat zone.

FOX Weather Correspondent Robert Ray is reporting live from Marquette, Michigan with the latest.

​

The massive March storm has saved its most shocking twist for the Deep South: snow is slamming Birmingham and parts of Central Alabama right now.

While residents were dodging Tornado Warnings just 12 hours ago, they are now watching large, wet snowflakes fall as a powerful Arctic front completes its takeover.

Because the ground remains warm from recent 70-degree days, accumulation is mostly limited to grass and rooftops, but the intensity of the flurries has been enough to create a surreal winter wonderland against a backdrop of spring blooms.

Due to the sudden increase in snow, the National Weather Service has issued a last-minute Winter Weather Advisory for portions of Northern Alabama and Southern Tennessee.

Forecasters are warning that while widespread accumulation isn’t expected, a quick dusting on bridges and overpasses could create treacherous slick spots for the midday commute.

This advisory joins a high-priority Freeze Warning already in place for tonight, as temperatures are expected to bottom out in the mid-20s across the region.

According to the latest data from FlightAware, the total number of flight disruptions is rapidly approaching a staggering 23,000 for the Sunday-to-Tuesday travel window.

As of midday Monday, the tally includes 16,079 delayed flights and 6,792 cancellations, as a dual-threat of blizzard conditions in the Midwest and violent thunderstorms in the East continues to overwhelm the U.S. air traffic network.

The pressure is now centered squarely on the East Coast. Ground stops have cycled through major hubs like Atlanta (ATL) and Charlotte (CLT) all morning, and a fresh ground stop was recently issued for Washington Dulles (IAD).

Even as storms clear some cities, massive backlogs and highs winds behind the main storm are keeping aircraft grounded.

With Spring Break travel at its peak, airlines are struggling to find open seats for the thousands of passengers displaced by the 6,700+ cancellations, leading to warnings that it could take until late in the week for normal operations to resume.

Severe storms are currently tracking through the Maryland suburbs just north of Washington, D.C.

A Tornado Warning is in effect until 12:15 p.m. ET for portions of Carroll and Howard Counties, as a severe thunderstorm capable of producing a tornado races through the region.

This fast-moving storm is part of the broader threat that is currently battering the Mid-Atlantic with damaging winds and intense rain.

Additional storms are expected to fire up across the region this afternoon and a Tornado Watch remains in effect until 7 p.m.

The Storm Prediction Center has expanded the Tornado Watch to include the densely populated I-95 corridor.

The watch now covers Philadelphia and Harrisburg, Pennsylvania; Dover, Delaware; and Atlantic City, New Jersey.

Right now, forecasters are most concerned with severe storms producing damaging winds gusts to 80 mph.

The northern edge of this life-threatening weather system is now just 20 miles south of New York City.

While the Five Boroughs are currently under a Wind Advisory and Flood Watch, the rapid expansion of this watch suggests that the atmospheric energy is holding together much further north than originally anticipated.

Residents from the Jersey Shore up to the Hudson Valley should be prepared for power outages and downed trees as these storms move at highway speeds, often arriving with less than 15 minutes of warning.

Forecasters at the Storm Prediction Center are closely monitoring a line of showers across Pennsylvania right now.

That line is expected to strengthen in the hours ahead and the severe weather threat will increase across the region.

The SPC says it will likely issue a Tornado Watch if conditions warrant it later today.

The ongoing March blizzard is more than just a major storm—it is a legitimate run at the history books. As of Monday morning, preliminary reports suggest that Wisconsin may have just witnessed its snowiest 48-hour period in recorded history.

Leading the charge is Mountain, Wisconsin, where a staggering 34.0 inches was reported via a local broadcast station. Close behind is Sturgeon Bay with a massive 33.2-inch total.

To put these numbers in perspective, the current all-time state record for a two-day snowfall is 33.0 inches, set in Iron County nearly 20 years ago in April 2007.

If these new totals are verified, this storm will officially become the new benchmark for extreme winter weather in the Badger State.

Current 2-day record: 33.0″ (Iron County, April 3–4, 2007)
Potential new record: 34.0″ (Mountain, WI, March 15–16, 2026)24-Hour record in jeopardy: The 1904 record of 26.0″ (Neillsville) is also being challenged by several stations reporting over two feet in a single calendar day.

These totals are currently preliminary. The State Climate Extremes Committee must now conduct a meticulous verification process—which can take months—to ensure the measurements were taken correctly and weren’t inflated by snow drifting before they are officially etched into the record books.

A Tornado Watch has been issued for Washington, D.C., and much of the surrounding Mid-Atlantic region until 7:00 p.m. ET as a rare severe weather outbreak threatens the area.

The watch is in effect as a powerful squall line begins to tap into record-high atmospheric energy, creating a volatile environment capable of producing tornadoes, large hail, and destructive straight-line winds exceeding 80 mph.

A ground stop has been issued for Washington Dulles International Airport (IAD), halting inbound traffic until 11:45 a.m. ET.

This specific freeze is targeted solely at flights departing from airports along the East Coast.

The restriction comes as the leading edge of a powerful cold front begins to squeeze the I-95 corridor, bringing heavy rain and increasing wind shear that is complicating the final approach for regional arrivals.

The monster March storm continues to take a heavy toll on the nation’s power grid. As of late Monday morning, more than 443,000 customers are without power across the eastern half of the U.S.

While utility crews have made some progress in certain regions, the combination of heavy, wet snow in the Great Lakes and high-velocity winds in the South is keeping outage numbers at critical levels.

Michigan remains the epicenter with 114,000 outages, as blizzard conditions continue to strain the local infrastructure. Ohio is also seeing significant disruptions with 54,300 customers in the dark.

Meanwhile, as severe storms push toward the coast, states like Pennsylvania (30.7K), Mississippi (22.4K), and Georgia (20.4K) are reporting widespread line damage from falling trees and intense gusts.

With the storm system now targeting the densely populated I-95 corridor, emergency management officials are warning residents to prepare for additional interruptions through the afternoon.

​

Extreme weather has crippled the nation’s airways, with flight disruptions soaring past a critical milestone this morning.

According to the latest data from FlightAware, more than 21,100 flights have been impacted between Sunday and Tuesday as the aviation industry struggles with a historic Midwest blizzard and a violent squall line tearing through the East Coast.

The numbers tell a staggering story of a system under siege: 14,761 delays have left millions waiting in terminals, while 6,350 cancellations have completely wiped flights from the boards.

While hubs like Chicago O’Hare (ORD) and Minneapolis-St. Paul (MSP) are still dealing with the Midwest blizzard, the pressure has shifted to the South and Mid-Atlantic.

Severe winds and thunderstorms have triggered rolling ground stops today at Atlanta (ATL), Charlotte (CLT), and Houston (IAH), creating a massive logistical backlog that is expected to ripple through the entire work week.

The Midwest blizzard is cementing its place in the history books this morning, with Three Lakes, Michigan, reporting a staggering 31.0 inches of snow. This nearly three-foot snow total comes within an inch of Michigan’s long-standing 24-hour snow record of 32.0 inches, which was previously set in Herman back in December 1985.

The Upper Peninsula is currently the epicenter of the storm’s fury, where lake-enhanced moisture is dumping snow at impossible rates.

For residents in Three Lakes and the surrounding Baraga County, the sheer volume of snow combined with 50-mph wind gusts has made the region a total whiteout zone.

With 31 inches on the ground, most secondary roads are completely buried, and local officials are warning that it may take days for crews to reach some isolated areas as the snow continues to drift.

In a stunning weather reversal, the same front that brought severe storms to the South yesterday is now ushering in snow flurries across Alabama.

As seen in local cameras this morning, large snowflakes are clearly visible falling over downtown squares, marking a rare March surprise for the Heart of Dixie.

While the ground remains relatively warm from recent spring-like temperatures, preventing major accumulation, the sight of snow falling against a backdrop of budding spring trees highlights the incredible temperature plunge currently sweeping through the Deep South.

A truly staggering amount of snow has been recorded in the Northwoods, with a massive 34.0 inches measured in Mountain, Wisconsin, as of Monday morning.

This historic total currently stands as the highest snow report from the “March Mania” storm complex, highlighting the extreme nature of the blizzard that has paralyzed much of the Upper Midwest.

To put that in perspective, parts of Oconto and Marinette counties have seen nearly three feet of snow in a single event, leaving many residents completely snowed in as plows struggle to clear roads amid ongoing 45-mph wind gusts.

The severe weather threat is ramping up across Virginia and Maryland this morning as the massive March storm begins its final surge toward the East Coast.

The FOX Forecast Center is closely watching a process called moisture advection—think of it as a giant invisible river of humid air flowing in from the south. At the same time, air high above is cooling down. This combination is like adding fuel to a fire, making the atmosphere extremely unstable and ready to pop.

We are already seeing some scattered storms forming ahead of the main line. While these early storms are unorganized, they are a sign of things to come.

The real concern is the wind shear, which is a dramatic change in wind speed and direction as you go higher up. Forecasters have noted that this spin is strengthening rapidly.

If any of these morning storms can tap into that energy, they could quickly produce a tornado.

​

However, the biggest danger is expected later this afternoon when a jet streak—a pocket of high-speed winds in the upper atmosphere—arrives.

The Storm Prediction Center says it will issue a Tornado Watch for the area, including Washington, D.C., in the hours ahead.

The scale of the atmospheric collision currently hammering the United States has reached a staggering milestone in the skies.

According to the latest data from FlightAware, the number of flight disruptions has now surged past 20,000 for the Sunday-to-Tuesday travel window. As of 9:50 a.m. ET, the total includes 5,600+ outright cancellations and a massive 14,400+ delays, leaving millions of spring break travelers stranded across the country.

The disruption is a perfect storm of logistical nightmares. While Minneapolis-St. Paul (MSP) and Chicago O’Hare (ORD) struggle to recover from 20-inch snowfalls and whiteout conditions that saw nearly 75% of flights canceled yesterday, the East Coast is now bearing the brunt.

Severe storms have triggered repeated ground stops this morning at Atlanta (ATL) and Charlotte (CLT), while high winds have forced a ground delay program at Houston (IAH).

With rebooking options nearly non-existent due to high spring break volume, airlines like Delta and United are warning that the ripple effect of these 20,000 disruptions will likely extend through the remainder of the work week.

A life-threatening situation is unfolding as a monstrous blizzard is unleashing feet of snow and vicious wind gusts throughout the Upper Midwest and Great Lakes.

More than 2 feet of snow has fallen in Wisconsin and Michigan since Sunday, with potentially historic accumulations expected in the Upper Peninsula.

FOX Weather Correspondent Robert Ray has the latest conditions in Marquette, Michigan.

​

The March blizzard isn’t done with the Midwest just yet. Forecasters are currently tracking a concentrated band of heavy snow stretching from eastern Wisconsin up into Michigan’s Upper Peninsula.

According to recent weather balloon data and radar imagery, the clouds in this corridor are packed with moisture and the air is cold enough to dump snow at a rate of 1 to 2 inches per hour through the rest of the morning.

The real danger, however, isn’t just the falling snow; it’s the wind. Powerful gusts are hitting these same areas, whipping the fresh snow into the air and creating ground blizzards.

This means that even if the snow slows down, the visibility on the roads can drop to near-zero in an instant.

If you are traveling along the I-43 or I-41 corridors in Wisconsin or anywhere in Upper Michigan, expect extremely dangerous driving conditions and “whiteout” visibility through the midday hours.

The combined force of a record-breaking blizzard and a severe weather outbreak has left nearly 485,000 customers without power across the eastern half of the United States.

According to the latest data from PowerOutage.com, the total number of outages has surged to 484,229, with the most significant damage concentrated in the Great Lakes and the Southeast.

Utility crews are facing a multi-front war, battling both whiteout conditions in the North and destructive squall lines in the South.

Michigan remains the hardest-hit state by far, with 132,000 customers in the dark as heavy, wet snow and 50-mph winds continue to snap limbs and bring down lines.

Farther south, the severe storms that triggered morning Tornado Warnings is taking its toll, with Georgia (32.6K) and Mississippi (24.8K) reporting widespread outages from wind damage.

As the severe storm threat shifts into the densely populated I-95 corridor this afternoon, officials warn that these numbers are likely to climb higher before the front finally clears the coast tonight.

A Tornado Warning has been issued for Charlotte and surrounding Mecklenburg County as a violent line of thunderstorms moves through the North Carolina Piedmont.

This dangerous storm, capable of producing a tornado and damaging 60-mph wind gusts, is part of the rare severe storm outbreak that forecasters have been tracking for days.

Residents in the path of this storm—including those in Uptown, South End, and University City—need to move to a basement or an interior room on the lowest floor immediately.

The warning comes as several Charlotte-area school districts have already shifted to virtual learning or closed for the day to keep students off the roads during the most volatile window of weather.

Because these storms are moving northeast at a staggering 60 mph, there is almost no time to react once a warning is issued.

Stay away from windows, abandon mobile homes for sturdier shelter, and keep your phone’s ringer on loud to receive life-saving alerts until the threat passes later this afternoon.

Hartsfield-Jackson Atlanta International Airport (ATL) is under a new ground stop this morning, with the FAA halting inbound traffic until 10:00 a.m. ET.

While the primary line of severe storms has already pushed east of the city, the ripple effect of the morning’s volatile weather is still paralyzing operations.

For the thousands of spring break travelers caught in the shuffle, this extension means even more time spent waiting at departure gates across the Southeast.

Officials are warning that even after the 10:00 a.m. freeze is lifted, the additional delay programs will likely remain in place for hours as America’s busiest airport attempts to untangle the logistical knot.

A fresh Tornado Watch has been issued for a large swath of Virginia and North Carolina as the East Coast prepares for a rare severe storm outbreak.

In effect until 2 p.m. ET, the watch covers major population centers including Roanoke and Raleigh area.

Forecasters are warning that today’s atmospheric spin is extremely high, meaning fast-moving thunderstorms could quickly develop into tornadoes or produce destructive wind gusts exceeding 75 mph.

With the storm line moving at highway speeds, there will be very little time between a warning being issued and the arrival of the storm.

If you are in the watch area, now is the time to ensure your FOX Weather App critical weather alerts are turned on and you know exactly where your “safe place” is—ideally a basement or an interior room on the lowest floor.

This watch joins an earlier one for parts of Georgia and South Carolina as the entire Atlantic seaboard braces for a volatile afternoon.

In a dramatic shift from the severe thunderstorms that plagued the Deep South on Sunday, frigid Arctic air is now carving its way across the region, triggering rare sightings of snow and sleet.

This morning, winter weather reports have been confirmed as far south as Mississippi and Louisiana, with sleet reported in Fayette and Natchez and snow flurries spotted in Byram.

While the accumulation remains minimal, the arrival of frozen precipitation in these areas highlights the sheer power of the freezer door being left open by the recent Polar Vortex collapse.

This sudden plunge into winter is creating a dangerous flash freeze scenario on the roads, too. As temperatures drop below freezing behind the cold front, any lingering moisture from yesterday’s torrential rains could turn into ice, making the Monday commute hazardous for drivers from Alexandria, Louisiana, through Jackson, Mississippi.

Yesterday was officially a day for the record books. According to the FOX Forecast Center, Sunday was the most active 24-hour period for severe weather in the United States in nearly nine months.

With 384 storm reports currently logged—a number that is still climbing as reports are completed—yesterday surpassed every major event since the widespread outbreak of June 25, 2025, which saw 389 reports.

If just six more reports are added to yesterday’s tally, March 15 will officially become the most active severe weather day since June 19, 2025, which holds the current benchmark of 453 reports.

Dangerous blizzard conditions are impacting millions in the Midwest with strong winds, feet of snow, and rough waves along Lake Superior.

FOX Weather Correspondent Robert Ray is LIVE in Marquette, Michigan with the latest as he continues his coverage from the bullseye of this storm.

​

The severe weather threat is increasing across the Deep South as the Storm Prediction Center has issued a Tornado Watch for portions of Georgia, Florida, and South Carolina until 2 p.m. ET.

This watch covers a region currently being hammered by a fast-moving squall line, with atmospheric conditions supporting both damaging wind gusts and the potential for a few tornadoes.

Residents in cities from Tallahassee to Savannah to Columbia should remain on high alert through the early afternoon, as these fast-moving storms are capable of producing quick spin-ups with very little lead time.

As the morning progresses, the scale of the massive March storm’s impact on air travel has reached staggering new heights. According to FlightAware, as of 8:00 a.m. ET, a total of 17,766 U.S. flights have been disrupted since Sunday, creating a massive backlog that is expected to haunt travelers through Tuesday.

This cumulative total includes 5,331 outright cancellations and 12,435 delays, as airlines struggle to navigate a volatile combination of historic blizzard conditions in the Midwest and a dangerous line of severe thunderstorms tearing through the Southeast and Mid-Atlantic.

With major hubs like Atlanta, Charlotte, and Houston already facing early morning ground stops, these numbers are climbing by the minute, turning what was supposed to be a peak spring break travel week into a massive test of patience for millions of passengers.

FOX Weather meteorologists Britta Merwin and Craig Herrera break down today’s rare severe weather threat along the East Coast.

​

Thunderstorms have triggered a morning ground stop at Charlotte Douglas International Airport (CLT), bringing a halt to inbound traffic from across the Southeast.

The FAA issued the freeze as storms move through the Carolinas, with the current stop in effect until 8:30 a.m. ET.

With over 15,000 disruptions already clogging the national aviation system, travelers at the American Airlines hub should prepare for significant gate holds and a ripple effect of delays well into the afternoon.

Travelers at George Bush Intercontinental Airport (IAH) are facing fresh disruptions as the Federal Aviation Administration has issued a new ground stop for flights heading into the Houston hub.

High winds trailing a powerful cold front have made operations unsafe, keeping the freeze in effect until 9:00 a.m. ET.

With north winds currently gusting up to 35 mph across the region, IAH joins a growing list of major airports battling extreme weather, adding further pressure to a spring break travel window already strained by more than 5,000 national cancellations.

If it feels like the weather is having a collective identity crisis, you aren’t imagining it. Our massive March storm is the byproduct of a massive atmospheric collision fueled by two extreme opposites.

Just last week, we witnessed a full collapse of the Polar Vortex. Normally, this swirling pool of frigid air is penned up at the North Pole by a strong, circular jet stream.

However, a major stratospheric warming event caused the vortex to split and buckle, effectively opening the freezer door and spilling a core of Arctic air deep into the American Heartland.

This disruption threw the jet stream into absolute chaos. Instead of a steady West-to-East flow, the jet stream has become highly wavy and fragmented, acting like a high-speed conveyor belt that is currently dragging that Arctic chill directly into a clash with record-breaking warmth.

As the jet stream dipped south, it tapped into a marine heat wave in the Gulf of America, where water temperatures are currently sitting as much as 10°F above normal.

This record-warm moisture is the high-octane fuel for the severe thunderstorms and tornadoes we’re seeing in the South, while the cold side of the same jet stream is manufacturing the historic blizzard conditions in the North.

When you combine a broken Polar Vortex with a fuel-injected Gulf, you get the volatile, split-screen extreme weather currently stretching from Texas to the Great Lakes.

A life-threatening blizzard is slamming the Midwest and Great Lakes with heavy snow, power outages and dangerous wind gusts.

FOX Weather Meteorologist Jane Minar is LIVE in Traverse City, Michigan this morning with the latest 

​

FOX Weather Correspondent Robert Ray is LIVE in Marquette, Michigan today as howling wind gusts and heavy snow slam the state.

​

For the first time in over 15 years, a Blizzard Warning is in effect for Milwaukee and much of Southeast Wisconsin.

The National Weather Service issued the rare alert as the storm intensifies, bringing a combination of blinding snow and powerful wind gusts of up to 45 mph.

The last time the Brew City faced a Blizzard Warning of this magnitude was during the historic Groundhog Day Blizzard of 2011, making this a generational weather event for the region.

The timing couldn’t be worse for the Monday morning commute. Conditions have deteriorated rapidly, with visibility dropping to one-quarter mile or less as the storm transitions from a wet, heavy snow to a drier, wind-whipped variety.

Milwaukee County Executive David Crowley has declared a Snow Emergency, closing all non-essential county facilities, including the courthouse and the Milwaukee County Zoo.

Residents are being urged to stay off the roads entirely, as plows struggle to keep up with the blinding whiteout conditions that are expected to persist until late afternoon today.

Travel across the heart of Iowa remains a dangerous impossibility this morning as Interstate 80 and Interstate 35 remain shuttered by the Iowa Department of Transportation.

Despite the snow tapering off in some areas, wind gusts of 50–60 mph are continuing to whip existing snow into ground blizzards, creating total whiteout conditions that have rendered the roads impassable.

As of 5:30 a.m. CT, I-80 is closed in both directions for a massive stretch from Council Bluffs (mile marker 8) all the way to Iowa City (mile marker 240). Similarly, I-35 remains closed from Ames north to the Minnesota state line.

The Iowa State Patrol reports that hundreds of drivers were stranded overnight, with emergency crews working in near-zero visibility to clear multi-vehicle pileups.

Authorities are maintaining a “Travel Not Advised” alert for the majority of the state, warning that even as plows begin to make progress, the combination of sub-zero wind chills and drifting snow makes any time spent on the road potentially life-threatening.

A rare and dangerous weather setup is unfolding today as a powerful storm system pivots toward the Atlantic Seaboard.

FOX Weather meteorologists are tracking a surge of warm, humid air—with dew points reaching the 60s—climbing as far north as Pennsylvania. This moisture is acting like high-octane fuel for an incoming line of storms.

Because the winds high above the ground are moving at incredible speeds (over 60 mph), any thunderstorm that forms today will be moving extremely fast.

This creates a double threat: first, a risk of individual, rotating storms called supercells that could produce strong, long-track tornadoes; and second, a sweeping line of storms capable of causing widespread wind damage as they pull those high-altitude winds down to the ground.

The window of greatest concern opens early this afternoon and lasts through the evening commute.

The FOX Forecast Center is particularly worried about the “spin” in the atmosphere, which is currently at extreme levels. If we see any breaks in the clouds that allow the sun to heat the ground, the risk for intense tornadoes will increase significantly.

Whether it’s a lone rotating storm or a solid wall of wind, the entire region from North Carolina up through the Mid-Atlantic needs to be on high alert.

Hartsfield-Jackson Atlanta International Airport has been brought to a standstill this morning as a Tornado Warning and intense severe storms triggered a mandatory ground stop for all inbound flights from airports in the Southeast.

The freeze, which is currently in effect until 7:30 a.m. ET, is causing a massive ripple effect across the Southeast, with the FAA halting traffic from major regional centers as a squall line moves directly over America’s busiest airport.

For spring breakers and commuters alike, this adds another layer of chaos to a morning already plagued by over 5,000 national cancellations, as lightning and 60-mph wind gusts make ground operations at the Atlanta hub impossible.

For thousands of students and families, the dream of a relaxing spring break has turned into a terminal-floor reality.

A massive weather system is currently gutting flight schedules across the country, with more than 5,000 cancellations and 10,800 delays reported so far.

From college juniors stranded in Denver to families stuck in Chicago, the historic March storm is hitting during one of the year’s highest-demand travel windows, leaving almost zero empty seats for those trying to rebook.

The disruption is a perfect storm of bad timing. While the Midwest struggles to dig out from record-breaking snow, the East Coast is bracing for a line of violent thunderstorms that will trigger ground stops at major vacation gateways like Atlanta, Charlotte, and D.C. later today.

Adding to the stress, travelers are reporting two-hour security lines and “ghost town” terminals where wait times for airline customer service have surged past the five-hour mark.

If you’re heading to the airport today, bring a charger and a lot of patience—this spring break is officially off to a rocky start.

In response to today’s predicted rare and dangerous severe weather outbreak, DC Public Schools (DCPS) has announced that all schools will close two hours early today.

The decision comes as the Storm Prediction Center places the District under a Level 4 of 5 risk for severe thunderstorms—a classification the region hasn’t seen in years.

By dismissing early, DCPS aims to get students and staff home before the most volatile window of weather begins.

FOX Weather meteorologists expect a powerful squall line to tear through the D.C. metro area between 3:00 p.m. and 7:00 p.m., bringing the threat of destructive 80-mph wind gusts, large hail, and tornadoes.

All after-school programs, athletic events, and evening activities have also been canceled to ensure families can remain sheltered while the front passes.

Power outages have skyrocketed as the storm system sweeps eastward, with over 546,000 U.S. customers currently without electricity this Monday morning.

One customer = one address, so the number of Americans without power could be dramatically higher.

Michigan is bearing the brunt of the infrastructure damage with more than 114,000 reported outages, largely due to the heavy, wet snow and high winds from the historic blizzard.

The outage map also highlights significant clusters across Ohio (61.5k), Texas (36.2k), and the Deep South, where severe thunderstorms and overnight tornadoes have downed lines across Mississippi and Georgia.

Utility crews face a grueling recovery effort as the volatile weather continues to move through the Mid-Atlantic and Northeast, threatening to push these numbers even higher as the day progresses.

To catch up on the initial wave of this historic March storm, you can revisit our coverage from Sunday.

We tracked the first confirmed tornadoes hitting Arkansas, the dramatic 137-year snow record set in Green Bay, and the emergency closure of I-80 and I-35 as blizzard conditions first took hold of the Heartland.
