Chicago is starting Saturday under light rain and fog, with temperatures around 66 degrees and visibility reduced to roughly 3 miles. The forecast calls for a waterlogged, windy day, with showers and thunderstorms continuing into the afternoon and a high near 72 degrees.

Heavy Rain And Gusty Winds Could Complicate The Day

Rain may become heavy through late morning, while thunderstorms could bring even stronger downpours. The National Weather Service Chicago says localized rainfall totals of 2 inches or more remain possible, raising the potential for pockets of urban flooding.

East-northeast winds will run 15 to 25 mph Saturday, with gusts reaching 35 mph. Saturday night stays unsettled, with showers and thunderstorms likely, a low near 65 degrees and another quarter- to half-inch of rain possible.

Lake Michigan Beaches Are Not A Saturday Plan

A Beach Hazards Statement remains in effect through Monday morning for Chicago-area Lake Michigan beaches. Waves of 6 to 9 feet and dangerous currents are expected, making swimming potentially life-threatening; beachgoers should also stay off piers, jetties, breakwalls and other shoreline structures.

Sunday Calms Down Before Sunshine Returns

Sunday brings only a slight chance of showers before 8 a.m., followed by mostly cloudy skies and a high near 72 degrees. Conditions turn noticeably quieter Monday, when sunny skies and a high near 75 are expected, followed by another sunny day near 80 on Tuesday.

A warmer stretch arrives Wednesday with a high near 81, although a slight chance of showers and thunderstorms returns after 1 p.m. Rain chances remain in the forecast Thursday and Friday, but neither day currently looks as soggy as Saturday.
