The arctic air that we have been tracking for over a week will maximize over the area Wednesday night into Thursday. The cold air will arrive via gusty northwesterly winds, which will produce stinging wind chills through daybreak Thursday.
We are in good company, with a good chunk of the central and eastern United States under wind chill advisories or warnings.
Winds will decrease after daybreak Thursday, so the wind chill effect will become less pronounced. Highs Thursday will be in the low to mid 20s, the coldest daytime highs since the end of last January.
After chilly lows in the teens on Friday morning, afternoon highs will reach the lower 40s.
