Shock to the system: Wind chills go sub-zero Wednesday morning

Monday's high hit 44° which made it the fifth day in the 40s this month. That satisfies the average number of days at least in the 40s during the month of January. Monday was also our 19th straight day above-average and Tuesday was the 20th straight day. 

Temperatures are still above-average in the upper 30s Tuesday but then fall quickly with a clear sky into the single digits to around 10° Wednesday morning. The chill is brief so temperatures warm back through the 20s Wednesday and don't really fall much Wednesday night. Highs get back to mild levels on Thursday and then fall back down around 30° for the weekend.

With lows in the single digits to around 10° Wednesday morning combined with the wind gusting to 30 mph the wind chills will go sub-zero for everyone. Some inland spots could get as cold as -15° for wind chills.
