Wednesday, April 29 came in on a chilly note for Milwaukee, with light rain and mid‑40s temperatures at Mitchell International Airport and a northeast breeze making the lakeshore feel extra raw. The damp start is expected to hang around through mid‑morning before the day creeps up to a cool high near 51°F. Drivers can expect wet roads and slower commutes, especially on bridges and in low‑lying spots.
According to NWS Milwaukee, skies stay mostly cloudy with a chance of rain showers through the morning and a smaller 20 to 30 percent shot at scattered afternoon showers and isolated thunderstorms. Any new rainfall should stay under a tenth of an inch. There are no watches or warnings in effect right now, but forecasters say overnight lows into Friday could slip into the mid‑30s, which opens the door for some patchy frost.
Afternoon Showers And Timing
The best window for any thunder or heavier showers is from midday into the late afternoon, although coverage is expected to be spotty and brief. If a stronger cell pops up, it could drop a quick burst of heavy rain and kick up some gusty winds, so drivers should be ready for sudden slick pavement and areas of standing water.
Overnight Frost Risk
Later this week, nighttime temperatures are forecast to dip into the 30s: near 37°F on Wednesday night, around 36°F on Thursday night and close to 35°F on Friday night. That is cold enough for frost to form in low‑lying and sheltered neighborhoods. Gardeners who have already put in annuals or set out tender potted plants will want to bring them inside or cover them for the next few nights.
