Any Shower Ends, then Sunday Heat
The southeast Wisconsin, Waukesha and Milwaukee forecast the rest of your Saturday night will include some scattered showers or a T'storm, but those gradually move out as the evening wears on. After that, there's a slim threat of a shower overnight. Overnight lows will be in the upper-50's for our lakefront communities and Milwaukee temperatures and low-60's for our inland areas and Waukesha temperatures.
Get ready for a huge change in the temperatures for your Sunday. After a slim threat of a morning shower, our temperatures are going to fly up into the low-90's as the day wears on. If you'd like a little relief, there may be a few times where we cool down right next to Lake Michigan. Expect some humidity to return as well. The Sunday summary is hot and humid.
Sunday night will be warm, but quiet with lows in the low-70's.
Monday will still be very warm, breezy and it will start off quietly. A cool front will be approaching in the afternoon. That could kick off some scattered showers and T'storms. Highs Monday will be around 90 with no relief next to Lake Michigan with a southwest wind.
Get ready for much more comfortable and quiet conditions on Tuesday. Highs will top out with comfortable readings in the low-70's.
