The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of your Saturday night will be nice and quiet. Overnight lows will bottom out in the low-40's under mostly clear to partly cloudy skies.
Sunday is still going to be really nice, but if you live near Lake Michigan, it will be cooler there. Skies will once again range between mostly sunny to partly cloudy without too much wind. Highs will top out in the upper-50's for Milwaukee's temperature and lakefront communities before falling there even more at times and upper-60's for Waukesha's and inland temperatures.
Sunday night will be okay for the most part, though there will be a slight chance of a shower overnight. Temperatures will be mild with lows in the mid-40's.
There will be a weak frontal boundary rolling through on Monday. This will allow scattered showers or a few T'storms to develop from the northwest in the morning first, then work their way to the southeast as the day wears on. No flooding rain is expected. Highs will top out in the upper-60's before possibly falling along Lake Michigan at times.
Monday night will be mild with a chance of scattered showers. Lows will bottom out in the low-50's.
Tuesday looks like it will be the warmest day of the whole upcoming week. There will be a slight chance of a storm, but most of the day will be fine. Right now, the forecast high is in the upper-70's, but if that lake breeze wins, folks by Lake Michigan wouldn't get quite that warm.
Chances of rain will hang on the rest of the week with highs only in the 50's for the latter part of the week.
