Had to put my jacket on when reviewing the 0zGFS. I would not get into the specifics of it yet. The GFS seems to be coming around the to long range teleconnection suggestions bthat decent ridges will be forming over favorable ares to bring down some good arctic air and perhaps a real winter for a change. The 1050+ highs are the hints that it is seeing this. Now will this all come together for good cold weather down here?
Because of travel back and forth across the Lake on Christmas Eve (Saints-Falcons game in the Dome!) and Christmas Day, I'm hoping for cold but dry weather. I wouldn't mind if we got a winter storm on Saturday the 23rd, though...with enough cold lingering the next few days to keep some snow around.
^^^^^^^ The problem is that it would be ice, not snow. This is reportedly a very shallow arctic air mass which means the upper air would be too warm for the formation of snow, or even sleet. It would be rain falling and freezing on the surface if temps are low enough. Believe me, you do NOT want an ice storm.
