The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of your Saturday night has some scattered showers and even an isolated T'storm. This activity will taper off later and then we could even see some patchy fog later. Yes, this is how we are going to start off December. Overnight lows will be very mild with temperatures bottoming out in the mid-40's.
Sunday will slowly improve as the skies gradually break a little and any fog dissipates. It will also be quite mild with highs in the mid-50's, though if you live by Lake Michigan, you might be cooling down as the afternoon wears on. Either way, a pretty nice day.
Tuesday looks a little bit cooler and dry. I'm not saying it's going to be cold by any means. Highs will top out around 50.
