December 2 2017
What is been advertised for a while is now on our doorstep. If you love cold weather or just winter in general, your time is coming! NOAA and the Climate Prediction Center is now joining the party to highlight the cold month ahead. The overall pattern is about to turn and tap into extremely cold air sitting overnight Siberia, Alaska, and northern Canada. You may hear the resurgence of the Polar Vortex that could make a visit across the northern US border. This is not like what we had in 2014 (yet), because that visit came at the coldest time of the year. Since there is plenty of land that is lacking snow cover to our north, some of this air mass will modify. But there will be no doubt next weekend… and much of this month. This is a reversal of the warm patterns we have had in recent years and getting snow to fall in some capacity before Christmas is looking pretty good.
This weekend will seasonal with near average and perhaps a good view of the SuperMoon Sunday. I will have more on that in my next report. There will be a warm up ahead of the arctic front on Tuesday and some areas will hit 60ºF. Then the bottom falls out. While the front will swing through Wednesday, the really cold air will settle in Friday and Saturday next week. Check it out:

Jumping Ahead… To Tuesday
This is the warm day ahead of the cold front. Temps will be near 60ºF but look for rain to arrive later in the day.
The Big News
Polar Vortex: It’s Back…
The core circulation that does circulate around the Arctic is going to drop south across the US/Canadian border next weekend. This will surge cold air across the eastern US and lock in for the rest of the month. Local high temps will be in the 30s or colder. Snow chances will increase and a hard freeze could reach into the Gulf Coast.
Cold Front And Cold Pattern Animation
This is the GFS Model showing the rain with the cold front… and then some flurries or light snow in blue. I do not place much credit on specifics beyond next Friday… but there will be a chance for our first flakes in the next two weeks.
Arctic Air Next Weekend
Compare the GFS Model outlook shown in the maps to the European Model (which has trended colder).
