Arctic air is on the way

I started talking about the events going on over the Arctic and how they would eventually mean cold air for the Carolinas. Now 2 weeks later the cold air in scheduled to moves south in 2 district waves.

The first of the cold air arrives this week with highs barely getting into the 40s. The next wave comes down the following week into early February. The second one might be even colder due to snow cover and the first batch establishing the cold air.
