A cold front moves through Wisconsin overnight with a dusting to a half inch of snow, but it brings the coldest temperatures of the season so far with lows in the single digits late tonight and wind chills near 5 below zero by morning. High temperatures on Thursday will struggle to hit 10 despite sunshine and brisk winds will keep wind chills between -5 and -10 all day.
Thursday night is the coldest of the season so far as temperatures drop to zero by midnight, even in Milwaukee. The wind will be light by Thursday night so the wind chill will not be a major factor, although still cold. Temperatures will rise slightly after midnight.
Another storm system moves in for Friday and snow is likely with high temperatures around twenty degrees. SE Wisconsin is expecting 3-6" of snow during the day on Friday with a light wind.
Saturday looks good with sunshine and high temperatures in the mid-20's and it will get above freezing on Sunday with a rain/snow mix likely. High temperatures will stay in the thirties for much of next week.
