Chicago residents should prepare for a dramatic weather shift this week — starting with strong storms Monday evening and ending with possible frost by Friday morning.
The National Weather Service has issued alerts for a line of thunderstorms moving through the Chicago area Monday night. Gusty winds and lightning could impact major routes including I-90, I-94, and Lake Shore Drive during evening commute hours. Temperatures will peak at 65–70 degrees before sharply dropping overnight.
Here’s where it gets dangerous.
By Tuesday, highs fall to the low 60s. Wednesday and Thursday bring temperatures into the mid-50s, with overnight lows dropping to 38–42 degrees — barely above freezing. By early Friday morning, lows could dip to 34–39 degrees, creating conditions ripe for patchy frost.
Communities west of the city face the highest frost risk — including Naperville, Joliet, Elgin, and Waukegan. If skies clear and winds die down Thursday night, frost could damage sensitive plants and outdoor vegetation by dawn Friday.
Residents in outlying and low-lying areas are urged to cover plants before Thursday night.
