Strong storm chances build early this week in southeast Wisconsin, with temperatures expected to reach the 70S on Sunday. Forecasters are also anticipating some thunderstorms over the night, with winds shifting out of the Southwestern Hemisphere, contributing to some SHOWERS and STORMS. Temperatures are expected to rise into the 70s on Monday, but temperatures will remain below the mid-70s on Tuesday. The forecast is expected to be more dry on Thursday before potentially seeing another chance for some SCATTERED SHOWERS or STORMS on Friday. There is a level two out of five for all of Southwestern Wisconsin as temperatures rise across the region.
