Overnight very cold air will settle in over SE WI. Lows will fall into the single digits above and below zero, and with gusty NW winds, wind chill values will drop to between -15 and -25°. Dress appropriately for these conditions, wear lots of layers, and cover exposed skin. Most of the area will be mainly clear overnight, but a quick moving wave will bring a few clouds and the chance for flurries south of Milwaukee.
After a VERY cold start Monday morning, conditions don't improve much for the afternoon. Highs only top out in the teens, but with breezy winds, it will feel like 0 to -15°. Skies will be mostly sunny.
Tuesday morning will again be very cold with lows in the single digits and wind chills well below zero. But Tuesday afternoon we see improvement with highs reaching around 30 under partly cloudy skies. It will be another breezy day.
The rest of the week looks fairly mild with highs in the 30s. There is a chance for light snow Thursday through Saturday, but the global models are in poor agreement, so check back later this week for an update.
