Trying to predict Chicago\u2019s weather is about as fruitful as guessing if any of our sports teams will have a winning season\u2014no matter the number crunching or the optimism, it\u2019s usually a lost cause.\u00a0But damn the torpedoes\u2014the\u00a0National Weather Service<\/a> is charging in with a fresh\u00a0batch of Midwest weather predictions. La Ni\u00f1a has arrived, and\u00a0meteorologists have some thoughts about it.<\/p>\n

According to the National Weather Service\u2019s Climate Prediction Center<\/a>, La Ni\u00f1a conditions have emerged in the Eastern Pacific Ocean. While\u00a0the \u201ccool phase\u201d\u00a0of the El Ni\u00f1o-Southern Oscillation climate pattern may be brewing half a world away, there are some real deal implications for Chicagoans. Here\u2019s everything you need to know about La Ni\u00f1a and what it means for Chicago\u2019s winter.<\/p>\n

What is La Ni\u00f1a?<\/p>\n

La Ni\u00f1a is part of the El Ni\u00f1o-Southern Oscillation (ENSO) climate pattern, during which a band of the Pacific Ocean\u2014just along the equator\u2014cools to a temperature lower than average due to trade winds nudging warm water westward. As a result, a cool pocket of air forms and initiates a domino effect: cold air begets\u00a0shifting jet stream patterns begets storm tracks slicing through the northern U.S. and Great Lakes region.<\/p>\n

How will La Ni\u00f1a impact Chicago’s weather this year?<\/p>\n

According to the National Weather Service, the upper Midwest and Great Lakes tend to experience above-average snowfall during\u00a0La Ni\u00f1a years. (Cue the collective groaning.) In the past, La Ni\u00f1a has\u00a0spawned disastrous\u00a0weather in Chicago: Longtime Chicagoans may recall the\u00a0Groundhog Day blizzard of 2011\u2014colloquially known as\u00a0\u201cSnowmaggedon<\/a>\u201d\u2014which yielded over 20 inches of snow, extreme whiteout conditions and treacherous high winds.<\/p>\n

As for 2025\u2019s winter weather prediction? The experts at the National Weather Service expect the current La Ni\u00f1a pattern to remain weak, but this could change as quickly as a Cubs fan\u2019s hope in October. The stronger La Ni\u00f1a becomes, the more likely Chicago will experience significant snowfall this winter. We\u2019re in for a long haul, too: La Ni\u00f1a is projected to stew until February 2026, so steel thyself for another humbling Midwest winter.<\/p>\n

What\u2019s the difference between La Ni\u00f1a and El Ni\u00f1o?<\/p>\n

Wannabe Tom Skillings\u00a0and self-appointed storm trackers\u00a0often conflate La Ni\u00f1a and El Ni\u00f1o. And, yes, they do bear some similarities: Both El Ni\u00f1o and La Ni\u00f1a are Pacific Ocean-based climate patterns that impact the weather on a global scale. Think of the two phenomena as two sides of the same forecasting coin:\u00a0El Ni\u00f1o ushers in warmer-than-average sea surface temperatures\u2014mainly in the central and eastern Pacific Ocean\u2014bringing dry and mild weather to the Northern U.S., more rain to the Gulf Coast and a quieter Atlantic hurricane season. La Ni\u00f1a, on the other hand, brings cooler-than-average surface temperatures to that same band of the Pacific, often\u00a0resulting in colder, snowier winters in the Northern U.S., dry conditions in the South and a stormier hurricane season.<\/p>\n","protected":false},"excerpt":{"rendered":"Trying to predict Chicago\u2019s weather is about as fruitful as guessing if any of our sports teams will…\n","protected":false},"author":3,"featured_media":304071,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5124],"tags":[10336,960,5386,1818,10337,1072],"class_list":{"0":"post-304070","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-chicago","8":"tag-categories-things-to-do","9":"tag-chicago","10":"tag-il","11":"tag-illinois","12":"tag-news-city-life","13":"tag-things-to-do"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/115375535816993605","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/304070","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=304070"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/304070\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/304071"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=304070"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=304070"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=304070"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
