Southeastern Wisconsin residents should prepare for a stormy Sunday afternoon as thunderstorms are forecast to develop, bringing the potential for heavy rainfall and localized flooding into the evening.
According to the National Weather Service, rain will start to pick up after 3 p.m., making travel conditions slower, especially along I-94 and other major routes in the Milwaukee area.
Sunday: Thunderstorms Likely with Heavy Rainfall
Thunderstorms are expected to develop across Milwaukee and surrounding areas, with a 60% chance of rain. The rain could be steady at times, and localized flooding is a possibility, especially in areas that experience heavier downpours.
Rainfall amounts will generally range from a tenth to a quarter inch, although some thunderstorms may produce more intense rainfall.
Winds from the south at 10 to 15 mph will push humid air into the region, driving afternoon temperatures into the mid-80s. The highest risk for storms will occur between late afternoon and mid-evening, with conditions tapering off overnight.
Residents are urged to have a backup plan for any outdoor activities, as the storms may cause disruptions. Additionally, if you plan on traveling, be cautious of flooded intersections or slower driving conditions due to the heavy rain.
The weather service has also warned that additional alerts could be issued if rainfall rates increase or if storms turn severe.
Monday: Showers Continue with Thunderstorm Possibility
On Monday, the rain chances will remain elevated, with more cloud cover and the possibility of additional showers or even a thunderstorm. The high will be near 83°F, with temperatures in the low 70s at night.

Tuesday: Brief Break in the Weather
Tuesday will provide a slight break from the storms, with only a 30% chance of showers, mainly before 1 p.m. The day will remain mostly cloudy, but temperatures will still reach a high of 83°F, making for a milder, more comfortable day.
