After a period of rain and storms Monday morning, severe potential develops Monday evening into Monday night. Questions remain as to how widespread and how far north this activity will develop, with the best chances along the WI/IL border. Keep up to date with the forecast!
Expect to see a morning round of showers and storms and depending how long the rain lasts may impact severe coverage and potential later in the afternoon and evening. The greater severe chances will be for southwest WI and toward the WI/IL border, but greater uncertainty further north.
Multiple rounds of rain and storms on Monday will bring a widespread 0.5-1 inch of precipitation across southern WI. Far southern WI along the WI/IL border currently shows the best chances for up to +1 inches of rainfall and could see pockets of +2 inches with any storms that track over the same area. This moderate to heavy rainfall may lead to urban/small stream flooding and add to or extend any ongoing river flooding.
