Forecast from FOX6 Chief Meteorologist Rob Haswell

MILWAUKEE - We’re settling into a pretty quiet start to the week, but don’t get too comfortable because spring is about to remind us who’s in charge.
After a calm Monday, temperatures start climbing fast into the 50s Tuesday and even low 60s by Wednesday.
That warm-up sets the stage for our next system on Thursday, which could bring rain and maybe even a rumble of thunder depending on how things line up.
Behind it, we cool back down into the 40s Friday before temperatures try to bounce back again next weekend. Bottom line, it’s a classic March pattern with swings, quick hits of warmth, and just enough uncertainty to keep things interesting
