An arctic air mass that could send temperatures into the teens Wednesday morning is expected to sweep across the Carolinas tonight, setting the stage for several cold days this week.
Another blast of cold air appears poised to arrive this weekend after a brief late-week mild trend.
National Weather Service meteorologists say temperatures will struggle to climb out of the 30s Tuesday in Charlotte, despite full sunshine. Highs in the northern foothills, in places like Taylorsville and Wilkesboro, might not get above freezing Tuesday.
One more mild day is in store for the Carolinas, although it wont be quite as warm as Sunday, when temperatures reached the middle 60s in the immediate Charlotte area.
Mondays highs are expected to reach the middle 50s, with sunny skies. Colder air will begin to arrive overnight, with Tuesday morning lows in the mid and upper 20s.
Then, with the arctic air pouring into the region, temperatures will rebound only slightly during the day. A wind chill advisory has been issued for Watauga and Ashe counties, with wind chills as cold as minus-8 degrees forecast for Tuesday. Air temperatures will be in the teens during the day, with winds gusting up to 35 mph from the west.
The forecast high Tuesday in Charlotte is 40, but many areas will not get that warm.
It would be the coldest day for the city since last Jan. 3, when Charlottes high was 36 degrees.
Morning lows Wednesday in Charlotte are expected to be in the upper teens, with afternoon highs rebounding slightly to the low and mid 40s. Highs in the low 50s are forecast Thursday, before Fridays arrival of another cold front.
That will allow more arctic air to arrive for the weekend, and forecasters say temperatures in that system might be a few degrees colder than the outbreak this week, with Saturdays highs only in the upper 30s.
