Milwaukee, Wisconsin – Brutal heat and a brewing thunderstorm threat will grip southeast Wisconsin Monday, July 28th, as summer weather turns dangerous again.
According to the National Weather Service in Sullivan, heat index values between 100 and 105°F are expected across much of southeast, east-central, and south-central Wisconsin, including Milwaukee, Waukesha, Jefferson, and Dodge counties. A heat advisory may follow if temperatures remain elevated through the day. Thunderstorms could develop after 1 p.m., with isolated strong storms possible into Monday night.
