A very impressive pattern setting up that I have been tracking and talked about for the past month and a half. This pattern that I alluded to at the beginning of November is starting to set up as we head towards winter. So it only figures as we head into officially the winter season nature snow guns will be full blown. We tried to get into this pattern at the start of December but the seasonal changes weren't quite ready. No stopping it this time as the global weather pattern is really something we haven't seen across the lower 48 states in years. Which means for the Lower 48 is a very active and a strong cold trough in the east in later half of December that will retrograde into January.
Now later this week the first of three storms will cross the US in the next 10-12 days. Two storms in the run up before Christmas, including one around Christmas Day. The idea of the nation's most widespread white Christmas since 2002. The modeling (GFS) is pulling its trending west and is still having its feedback problems. So instead of the storm moving east and continuing right off the Carolina coast. I believe there will be a lot of 1-3 inch amts are likely from Missouri to the Mid-Atlantic States. With a heavier snows from interior Carolina to the Delmarva with a 3-6 inch swath into the weekend
At the least, a lot of 1-3inch amounts are likely from Missouri to the mid-Atlantic states with number one with heavier snow in the interior Carolinas to the Delmarva, with the possibility of amounts of 3-6 inches or more on the weekend all the way back to the big cities from DC to NYC and BOS with heavier amounts southeast of that. I expect to see the trend now starting from nothing two days ago from South Carolina northward to a full quick moving moderate size snowstorm up the coast.
Then next is Christmas week and the possible crimpling Christmas storm. First starting into the Pacific Northwest then diving southeast quickly with the Arctic front. These will then join up with the southern jet stream and develop a low pressure across Texas. This will help to produce snow, sleet and freezing rain to the north and heavy rains to the south. Right now I believe heavy snows are possible from the Southern Plains east to Ohio and Tennessee Valleys then northeast into the Mid-Atlantic. As by December 26th there will likely be a lot of the country under snow.
If this wasn't enough another storm will likely move just to the south of the previous storm track. As money in the bank scenario looks to take shape just before New Years. As the trough and polar vortex shifts west and stregthens the southern jet. Energy in the southwest comes out and snow could fall pretty far south with the newest addition of cold air by the year 2010.....Below is the current snow cover across the United States.
