Cold weather to stay, maybe some more winter weather down the road??

Well we have had a nice few days from the real cold with highs Wed and Thurs getting into the 50s and upper 40s, compare that to where we have been most of the winter and thats warm but upper 40s is really our normal. Not so fast though all my warm weather friends more cold is in store, along with the POSSIBILITY of wintry weather. Heres what I mean take a look at this image on the left is the EC (Euro) model and on the right is the GFS (US) model.

This is the 10day mean, and you can see that big ridge out west keeping warmth in the west and a arctic flow out of the NW into the east/se US. Now the blue lines I have drawn show areas of troughs that can produce upper lvl energy needed to combine with cold air from the north to produce winter storms in the eastern/se US.
Now lets take a look at the GFS week 1 ending temps, (this is the mean departure from normal)

On this the real brutal cold will stay up in the NE and New England, BUT that does not mean us here in the south will get off, in fact arctic air is set to invade starting Friday into early next week as another southern system may produce wintry weather here in NC but thats a another story Ill have later.

And then we take a look at week 2 ending Feb 3rd mean temp departures and, yes more cold to stick around.

Well thats it at this time Im leaving town tonight but should be back Sunday evening to post an update on our possible storm.
