The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of the night has a chance of scattered showers and T'storms later tonight. The further you live to the north, the lesser the chance of storms tonight. Lows will be in the upper-60's.
There's a slight chance of a morning T'storm on Saturday, but most of the day will be just fine, except for the heat. Highs will top out in the upper-80's for our lakefront communities and Milwaukee temperatures before cooling down there and low-90's for Waukesha and inland temperatures.
Most of Saturday night will be fine with lows in the upper-60's under partly cloudy skies.
