Chicago wakes up to mostly cloudy skies and mid-50s temperatures this morning, sitting around 55°F. Those numbers will not stay low for long. A steady push of southerly air is expected to send afternoon highs into the low 70s, setting the stage for a breezy day and a stormy night.
Afternoon Winds Pick Up
South to south-southwest winds are forecast to ramp up to 10–15 mph, with gusts reaching up to 30 mph. That should keep inland neighborhoods warmer than the lakefront through the afternoon. On the water, conditions get a bit rougher. The nearshore zone is under a Small Craft Advisory, and the National Weather Service is urging small-boat operators to use extra caution through this evening.
Overnight Storms Loom
Scattered showers could brush the area before daybreak, but the main event is expected late tonight into early Saturday, when thunderstorms become more widespread and likely. Forecasts put the chance of precipitation overnight at about 70%, with new rainfall totals in the one tenth to one quarter inch range and a risk of localized gusty winds.
The Storm Prediction Center has the Chicago area under a marginal severe risk for that period, according to NBC 5. If you have late plans, keep an eye on updates and be ready to dodge a few downpours.
Weekend Warmth And The Week Ahead
Saturday is expected to reach highs near 82°F, with only scattered showers and thunderstorms mainly south of I‑80. Sunday and Monday look even hotter, with highs in the mid-80s. Forecast guidance points to a better shot at organized showers and thunderstorms Monday into Tuesday as more Gulf moisture returns, which in turn raises the odds for stronger storms. If your schedule is flexible, it might be smart to front-load outdoor plans into the weekend or at least have a solid indoor backup ready for next week.
What To Do Today
If you are heading to the lakefront, tie down loose gear and steer clear of small boats while the advisory is active. For tonight's outings, plan for gusty winds and bring a rain jacket, since storms could deliver brief downpours and spotty strong gusts that might topple temporary canopies. Travelers should also stay tuned to updates overnight, as both airports and major roadways could see short-lived delays from heavier showers.
