Northern Illinois residents should prepare for a significant rainstorm, expected to bring up to six inches of rain across areas like DeKalb and Ottawa from Saturday night through Tuesday. The National Weather Service warns that this extended downpour could cause flash flooding, particularly around major roadways, including I-80 and I-55. Clearing leaf-clogged storm drains today and Saturday can help reduce flooding risks as heavy rain intensifies.
According to the National Weather Service’s latest update, areas like Dixon, DeKalb, and Ottawa could see rainfall totals between 4 to 6 inches, while other northern Illinois locations like Chicago and Joliet may experience around 2 to 4 inches. The rain is expected to start as early as Saturday night, with showers and thunderstorms continuing through Tuesday morning. Windy conditions could accompany the rain on Monday, heightening potential for localized flooding and difficult driving conditions.
The weather forecast for the days ahead in Chicago indicates that today will remain sunny with highs around 51°F, while Saturday will bring partly cloudy skies with a slight chance of rain in the evening. Rain chances rise sharply Sunday and are forecasted to remain through midweek, intensifying overnight Sunday into Monday, which could see the heaviest rainfall. Highs will hover near 60°F through Tuesday, with breezy conditions.
Residents are advised to monitor weather updates closely and consider precautionary measures, especially if traveling through areas prone to flooding.
