Areas of Severe Thunderstorms and Excessive Rainfall Friday

A wave of shower and thunderstorm activity is expected to build into the region late tonight (after midnight) and continue into Friday morning. Storms should become more isolated into Friday afternoon, possibly rebuilding to scattered coverage Friday night before drying out into Saturday. Only 25-30% chances for a few showers or storms to redevelop Saturday or Sunday, mainly in far southern and southwestern WI. Inland high temperatures should be in the 80s each day, with lake breeze circulations providing some relief from the heat to the immediate shoreline of Lake Michigan. For Sunday, the synoptic wind field will turn east and cool off much of eastern WI. Progressively warmer and more humid conditions are expected through next week.
