Clouds have rolled in and there could be some freezing drizzle or drizzle after midnight and even a dusting of snow by the morning commute.
Low temperatures will be near 30 by morning, and that is also the high temperature for tomorrow as strong northerly winds at 15-30 mph will drop the temperatures on Tuesday into the lower-20's and wind chills in the single digits. Light snow is likely throughout the day with most of southeast Wisconsin receiving 1"-3" of snow by evening.
The sky clears slowly Tuesday night and it gets very cold with low temperatures near zero and wind chills as cold as -10.
Wednesday will be sunny but cold with high temperatures near 20 degrees and wind chills near zero.
Another cold front moves in Wednesday night and high temperatures on Thursday will be in the teens with light snow and little accumulation. High temperatures remain in the teens on Friday before a weekend warm up with high temperatures in the mid-twenties on Saturday and upper-thirties on Sunday with a rain/snow mix developing.
We could see temperatures soaring back to around forty degrees again by Monday.
