Milwaukee is starting Wednesday with overcast skies and temperatures around 61 degrees, but the calm opening comes with a lakeshore warning and a wetter pattern building toward the weekend. The city should reach near 70 degrees under mostly cloudy skies, with a 30% to 70% chance of precipitation.

Dangerous Lake Michigan Conditions Continue Through Noon

A Beach Hazards Statement remains in effect through noon Wednesday for Milwaukee and Racine counties, where waves of 3 to 5 feet and dangerous currents are expected, according to the National Weather Service. Swimmers should stay out of the water and away from piers, breakwalls and other exposed shoreline structures.

Showers Return Overnight

Wednesday night will stay mostly cloudy, with temperatures dipping to around 63 degrees and a 30% chance of showers after 1 a.m. Thursday brings a high near 70 degrees, with a slight chance of showers followed by mostly cloudy conditions.

The updated beach advisory and shifting rain chances sharpen the outlook covered in an earlier Hoodline forecast. Friday should be mostly sunny, followed by showers Friday night.

Stormier Stretch Takes Over This Weekend

Friday night into Saturday could bring showers, with more showers Saturday morning and a high near 73 degrees. Another system could bring rain or storms later in the weekend, keeping outdoor plans vulnerable to interruptions.
