The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of your Saturday night will be comfortable. There isn't a chance of rain, so you can open your windows. Overnight lows will be in the low-60's.
We're going to be a little warmer again for Sunday. There's a weak low pressure passing to our south, and that will bring us a slight chance of an afternoon shower or T'storm. Highs will top out in the low-80's with an easterly wind for our lakefront communities and Milwaukee temperatures and mid-80's for our inland areas and Waukesha temperatures.
