After our rainy day off in the 50s, the cold is back in full force to stay for a while. There are some scattered flurries and snow showers behind the cold front today and temperatures are hovering in the 30s, but a secondary rush of cold air will come in later this afternoon/evening setting up the 2 coldest days of the season upcoming. Temperatures will drop to the upper 10s and low 20s by tomorrow morning and highs will only top out in the mid 20s. Winds will be gusty (over 30 mph at times) making wind chills in the single digits, however. There will continue to be scattered snow flurries and snow showers throiugh Tuesday evening. Gusty winds will continue into Wednesday with temperatures topping out in the upper 20s to around 30. The winds will lighten up and temperature will not be as cold for the remainder of the week, but will remain below average. Will monitor a storm system later Thursday that looks to shoot south of our area potentially bringing some wintry precipitation to the southern mid-Atlantic states.
The later part of this weekend is when things could get very interesting. There is the potential for a significant winter storm along the east coast Sunday into Monday as the various computer models are all at least showing the players on the field to make it happen. For one, we have an excellent blocking pattern developing across the north Atlantic/polar regions that will persist over the next 10 days at least. If you don’t know what that means, I’ll just say that it is a feature that’s typically present and often necessary for northeast snowstorms to occur, including the big ones of the past. It is not a guarantee by any means, but a very good signal to see if you want a snowstorm. As we get closer to this time-frame, it will come down to when and how the actual features that will be responsible for spawning this storm interact with each other. It is an issue of timing and the computers will be back and forth with this storm because it is still 6 days out. Because the Pacific weather pattern is not very favorable for this event it is very possible that it could throw the timing off. If the ingredients come together too late, then the storm would form too late and too far to the east. If they gather too early and too far to the west then we could get all rain, though at this early stage in the game I think that is the least likely scenario.These are all possible scenarios though, and details that will hopefully start to become clearer in the next couple of days. Just keep an eye out for Sunday to Monday (Dec. 19th-20th).
If this does not materialize, the weather pattern still looks potentially threatening for wintry threats as we continue into the next work week. We would be getting pretty close to Christmas at that point.
