The East will get Cold for the Holidays!
Short Range: Light snow will move across the Northern Plains today and tomorrow. Generally 1-3 inches of snow with both events.
Rain is moving across the Ohio Valley into the Northeast today and tomorrow then that band of rain will get stuck across the Ohio Valley and Mid-Atlantic. The storm that develops in the southern Plains Thursday will have some wet snow from the Midwest across the southern Great Lakes into the central Appalachians. This will be a very marginal event.
This weekend, a storm will move into the West. That storm will be very heavy snow to the Sierra’s and Cascades and heavy rains into the central and northern California. Rain and snow will move into the southern California and Arizona, Nevada, and Utah by Sunday. The mountains will see heavy snow and travel through the passes will be very poor.
That storm will eventually move into the Plains early next week. Both the GFS and ECMWF suggest that a massive blizzard will hit areas from eastern Colorado into the Dakotas with severe storms along the cold front. Looks like a wild storm coming up next week which is not unexpected given the pattern we are going into.
Long Range: Between now and the 15th, the PNA will stay negative which means the storm track will be in the Plains to the Great Lakes. After the 15th, the PNA will go positive and the AO will stay highly negative and the NAO will stay negative. All this means that we are entering a period of extremes with snowstorms, mix events and severe weather that will last through the Holidays. What is certain, the weather will turn colder or have extreme cold shots through the holidays which is something I have been talking about since November. At some point, one of these storms will hit the coast and blow up into a Big Daddy. Not sure which one yet, but the GEFS model suggests that the 19th storm is the one that may do it.
