NWS had decent weather projected for the SE through next Thursday. Now, the forcast has been moved up and the frigid air will hit on Monday. (3) day shift toward below normal temp's. Gandold is moving faster than forcasted which means it will penetrate deaper than projected into the whole US. Duration of the artic blast is still be calculated.
I believe this one will be called Gandold the great white...projecting 18" in some areas and building strength. This warmer weather in the SE is like a warm gulf for a Hurricane. The heat is turning into water/snow/ice/sleet and it will be deep.
