The first day of fall in Southeast Texas is feeling less like sweater weather and more like a classic Houston September.
SE Texas should expect rain and isolated thunderstorm chances mainly south of I-10 starting in the morning, with another round possible in the afternoon.
Monday’s Forecast
Temperatures are expected to reach the upper 80s and 90s through the start of the week, with humidity remaining high and rain chances climbing. While some showers and maybe a thunderstorm are likely on Monday—mainly along the coast in places like Lake Jackson and Freeport—areas without rain may still see highs near 90 degrees.
Morning showers and storms mainly near the coast
Thunderstorms are most likely to fire up south of Interstate 10 as the day progresses. By evening, most of those showers are forecast to taper off.
At 1:19 p.m. on Monday, it will be the official start of fall, when the direct rays of the sun are over the equator.

Tracking a cool front Thursday:
Thursday a cool front moves through Houston. This isn’t a particularly strong front so we won’t see a drastic drop in temperatures but it will bring drier air for the end of the week and into parts of the weekend. Enjoy the lower humidity to end the work week!
Rain chances ramp up Thursday, with cooler less humid behind the cool frontTropical outlook:
Hurricane Gabrielle is still expected to slide east of Bermuda and out into the north Atlantic. It will briefly become a major hurricane Tuesday as it moves northeast.
Will bring no impacts to the United States but Bermuda will need to watch for high surf, rain and increase winds as the storms stays east of the island.
There are two tropical waves in the Atlantic stirring up disorganized thunderstorms. They will have to overcome wind shear to form into anything organized. One has a 50% chance of developing over the next 7 days, the other only has a 20% chance.
