Arctic Blast This Week To Be Followed By Another Next Week As NAO, AO Go Neg

Written by on November 13, 2013 in United States of America with 0 Comments

Arctic air continues to blast south this evening and it sure has grabbed the attention of millions of shivering Eastern and Southerners. As the front has steamed through, we’ve seen rain change quickly to snow, gusts past 40 mph, thunder and lightning and temperature drops of 10+ degrees within just 1 hour. 24 hour drops have been in the order of 25 to 35 and in some causes 40 degrees.

We also saw record snowfall, albeit a trace in many areas stretching from Maine down to North Carolina.

This evening there are countless snow images being uploaded to twitter from North Carolina as the front crosses the mountains and pushes ever closer to the coast.

Here’s the current radar over North Carolina and you can clearly see the front with rain on it’s leading edge with backside snows. Note the moisture is limited but that’s an impressive front. According to TWC, Charlotte was up to 65 degrees earlier and is now down to 35 and will drop into the 20s tonight beneath clear skies.
