Forecast from FOX6 Chief Meteorologist Rob Haswell

MILWAUKEE - Monday's forecast still hinges on the timing of morning thunderstorms, which could impact everything from severe weather potential to whether parts of southern Wisconsin need a Heat Advisory. If enough sunshine breaks out this afternoon, another round of strong to severe storms could develop along an approaching cold front with damaging winds, large hail and even a brief tornado possible. Once the front moves through, cooler and noticeably less humid air settles in Tuesday with highs mainly in the lower 80s. If you're headed to Lake Michigan, be aware of a high swim risk from Tuesday into Wednesday morning. Heat starts creeping back Thursday before another chance of showers and thunderstorms arrives late Friday into Saturday.
