Much colder just in time for Christmas...

Much, much colder air has arrived around the region, and it will be here to stay, by and large, for quite some time.

Lows tonight will head into the lower 20s in many Piedmont spots, and I fully expect the normally colder locations to dip into the upper teens.

Christmas Day will be quite chilly in spite of full sunshine with highs in the upper 30s and lower 40s in many Piedmont spots.

There continue to be signs of a fairly cold and possibly unsettled pattern in the eastern US in the longer range. See the video for more.

Have a wonderful Christmas!
