Chicago started Wednesday, April 29, 2026, under a deck of stubborn gray clouds, with temperatures hovering near 54°F at Midway Airport. Isolated rain showers are possible before 4 p.m., and a steady north wind of 10 to 15 mph will cap afternoon highs near 50°F. It will not be a total washout, but if you have daytime plans, a warm layer and a small umbrella are smart accessories.
Afternoon Showers And A Nagging North Breeze
Spotty rain showers are most likely from late morning into early afternoon, with totals generally under a tenth of an inch and about a 20% chance of precipitation. North winds of 10 to 15 mph may gust higher in open areas and will keep the chill locked in, with neighborhoods near the lake running a few degrees cooler. These details come from the National Weather Service in Chicago.
What To Do
Leave a bit of extra time for the commute, since brief, hit-or-miss showers can slick up the streets for a few minutes. Gardeners will want to move potted or tender plants indoors or cover them before Friday night if you live away from the immediate lakeshore.
Weekend Outlook And Frost Risk
Overnight lows will slide into the low to mid 30s, and Friday night into Saturday morning is the period most likely to bring widespread frost. After that chilly dip, temperatures bounce back into the mid 60s by Sunday and Monday, though a series of passing disturbances will boost the chance for scattered showers and a few thunderstorms early next week. Forecasters at the National Weather Service Chicago highlighted both the frost potential and the shift toward a slightly wetter pattern in their latest discussion.
Quick Tips
Pack a light jacket and a compact umbrella for any quick afternoon drizzle, and remember that shoreline spots will feel a few degrees cooler thanks to the lake breeze. If you are trying to protect plants, plan your move for Friday night, when calm, clear conditions will give temperatures a good chance to drop into the frost range.
