Skies will become increasingly cloudy tonight; even so, temperature will fall to the lower single digits overnight. At least the winds will be light, so wind chills should not be a factor.
A winter storm system will move into Wisconsin on Sunday. Skies will be mostly cloudy with light snow developing by the afternoon and continuing through very early Monday morning. Snow amounts will be in the 2-5" range from Sunday afternoon through Sunday night. Highs on Sunday will be in the lower 20s.
The coldest air of the season will arrive after the storm passes, with temperatures falling from the middle teens on Monday through the lower teens during the day. By Tuesday morning, low temperatures will be near -5, but wind chills could fall to as low as -25. Tuesday will be partly sunny with highs only reaching the single digits. Some flurries will develop from Tuesday night into Wednesday, otherwise it will remain bitterly cold with temperatures starting below zero and ending the day around 10 above zero. Wind chills will be as cold as -20 Wednesday morning.
On Thursday, temperatures will remain very cold, and skies will be partly sunny, although there is a slight chance for flurries. High temperatures will be in the upper teens. Friday will see increasingly cloudy skies, and with breezy southerly winds, temperatures should climb back to the upper 20s for highs.
A weak weather system may bring some light snow Friday night into Saturday of next weekend. A strong storm to our southeast on Sunday may also bring a chance for snow. High temperatures will be in the lower 20s on Saturday, and in the upper 20s on Sunday.
