Milwaukee is starting Sunday under a gray lid of mostly cloudy skies and patchy fog, with temperatures hovering near 41°F at General Mitchell International Airport and pockets of reduced visibility along lakeside roads. The fog is expected to thin out by mid-morning, opening the door to a milder afternoon near 55°F, though lakeshore neighborhoods should stay a bit cooler under an onshore east wind. Attention will turn quickly to Monday, April 27, when a stronger low pressure system is expected to drive widespread showers and thunderstorms into the area.
Sunday Snapshot
Patchy fog is most likely before 8 a.m., then skies should shift to mostly to partly cloudy with east winds around 5 to 10 mph and highs near 55°F. Areas closest to the lakefront can expect temperatures a few degrees lower and a somewhat breezier onshore flow. These timing and temperature details come from the National Weather Service Milwaukee.
Monday Outlook
On Monday, April 27, a deepening low pressure system is set to pull warm, moist air north into southern Wisconsin, sending the high to around 64°F with a strong southerly wind. Showers and thunderstorms are likely by morning and should become more widespread through the afternoon and into Monday night, with wind gusts up to 30 mph possible. Forecasters note a risk for severe storms in parts of the area and project new rainfall totals of 1 to 2 inches Monday night, enough to cause standing water on streets and pockets of localized flooding.
Impacts And Planning
If you have outdoor plans Monday, it is worth moving them inside or rescheduling, since heavy rain, gusty winds and lightning could disrupt events and commutes. Boaters should keep a close eye on nearshore conditions, as advisory-level winds are possible, and road or construction crews should be ready for waterlogged work zones. We tracked this active pattern in our April 15 coverage on fog, flood fears and thunder, which offers more background on the repeated storm risks.
Bottom Line
Look for a foggy start and a mild Sunday, then a quick shift to a much wetter setup on Monday, April 27, with fast-changing conditions and possible travel issues. Before heading out, check the latest updates from local officials and the National Weather Service.
