The southeast Wisconsin, Waukesha and Milwaukee forecast for the rest of your Thursday has a few stray flurries or possibly a lake effect snow shower in the far southeast, Highs today will be around 30 under mainly cloudy skies.
Tonight, with an easterly wind, we could see a few lake effect flurries or a snow shower right along Lake Michigan. Most of the area, most of the time will be completely quiet. Overnight lows will bottom out in the mid-20's for our lakefront communities and Milwaukee temperatures and around 20 for inland areas and Waukesha's temperatures.
As the day wears on Friday, snow will slowly be developing from the west. The morning commute, at the moment doesn't look to be that problematic. The main batch of snow will roll through in the afternoon. By the end of the day, 1-2" should be on the ground. Highs Friday will top out in the low-30's without much wind. The snow will be light and fluffy to move around.
On the back side of this system, we still could hold onto a flurry or snow shower, but any accumulation Saturday would be light if anything at all. Highs will top out in the low-30's.
Things look cool and quiet rolling into the New Year.
