Heavy Rain, Flooding, Cold Front Thursday Night: NWS

MILWAUKEE, WI — The National Weather Service says that rain showers and thunderstorms will produce heavy rainfall Thursday that may lead to flooding today and tonight.

Southeastern Wisconsin has already seen between two to six inches of rain since Monday night, with much of this rain coming in the last 24 hours. There is increasing concern for flooding as multiple rounds of rainfall the past few days have resulted in saturated soils. A Flash Flood Watch has been issued for all of southern Wisconsin.

The heaviest rainfall will be focused west of I-90. Isolated rainfall amounts upwards of two inches are possible across the entire area. The National Weather Service says thunderstorms will enter Southeastern Wisconsin starting around 6 p.m., with the wet weather hanging around until at least 7 a.m. Friday.

Showers and thunderstorms will slowly move north across the area Thursday ahead of an approaching system. Moderate to occasional heavy rain is possible today. Another round of showers and storms are expected tonight as a cold front sweeps across the area.

Strong to severe storms are possible later tonight with the cold front.
