The stretch will feature clear, frigid nights early on, followed by a noticeable warmup and a return of unsettled weather by mid to late week.

Sunday will be bright but sharply cold, with sunshine pushing temperatures to a high near 21. Wind chills on Sunday may dip as low as 2 below zero as north winds blow at 10 to 15 mph, occasionally gusting near 20 mph and keeping conditions feeling much colder than the thermometer suggests.

Wednesday Night becomes more unsettled, with a slight chance of showers early, then a better chance of showers and thunderstorms after midnight. On Wednesday night, mostly cloudy skies and gusty south winds of 5 to 15 mph are expected, with gusts up to 25 mph, will keep temperatures around 45.
