Chicago Weather: Severe Storms and Snow Expected Tonight A cold front is moving through Chicagoland today, rapidly lowering temperatures from the 60s into the 30s. Strong to severe thunderstorms are anticipated this afternoon and evening, with the highest risk for severe weather between 4 PM and 9 PM. The Storm Prediction Center has placed most of the region under a Slight Risk, which is the second level out of five. While damaging wind gusts are the primary concern, an isolated tornado cannot be ruled out. The most significant threat for severe storms is near and south of I-80. Following the thunderstorms, the weather will shift to wintry conditions. Rain is expected to transition to snow tonight, with impacts on Monday’s morning commute. A Winter Weather Advisory has been issued for McHenry, Lake, DeKalb, Kane, DuPage, northern Cook, LaSalle, and Kendall Counties. The advisory covers 1–3 inches of snow and wind gusts up to 45 mph, effective from 10 PM tonight through 1 PM on Monday. Monday will be cold and windy, with high temperatures in the 30s at midnight, dropping to the 20s by daybreak. Temperatures will remain in the lower 20s throughout the day, with wind chills in the single digits. On-and-off snow will continue through Monday evening. Temperatures will plummet into the single digits near 10 degrees Monday night and early Tuesday, with wind chills likely dropping below zero by Tuesday morning. Partly to mostly cloudy skies are expected on Tuesday, with highs in the low to mid-20s. Warmer air is set to arrive by Wednesday, with highs in the upper 30s to near 40 degrees. There is a chance of light snow in the morning, but skies will clear during the day with some sunshine in the afternoon.#chicago #storm_prediction_center #i_80 #winter_weather_advisory #mc_henry
