Chicago, IL — A powerful holiday-week storm system could bring heavy rain, snow, and travel delays across the country, with Illinois positioned for some of the most significant Thanksgiving impacts.
Nearly 82 million Americans are expected to travel this week, and meteorologists warn that both road conditions and airport operations may be affected—especially in and around Chicago.
A Large Stormfront Aims for the Midwest
Forecasters from AccuWeather report that a massive storm system is sweeping across the United States, carrying thunderstorms, steady rainfall, and eventually snow. This storm is expected to reach the Midwest by Tuesday, heightening the likelihood of flight delays at Chicago’s major airports, including O’Hare and Midway.
According to the National Weather Service (NWS), both northern and central Illinois are at risk of accumulating snow as Thanksgiving weekend approaches. In particular, the Chicago area may see snowfall Saturday into Saturday night, while central parts of the state have a 20–40% chance of receiving two inches or more late Friday night into Saturday.
