Polar Vortex Coming?????

I read the story below and a little concern it might be premature given the modeling evidence suggests that the cold is coming by Mid-January. But just how cold and extreme will the weather be remains to be seen. The SOI values have flipped to La Nina which is a better indicator for colder weather in the East and Northeast but below normal snowfall in those areas.


I think through the holidays I think temperatures remains above normal but still a little snow coming through parts of the Great Lakes and Northeast. It may remain mild into January but should switch to colder by mid-month. Not sure how extreme the cold will be yet.


Northeast Snow, Could be Heavy Today into Monday

A storm coming up the coast that is producing mainly rain this morning should transition over to snow from Northeast Pennsylvania into eastern Maine.

Snow will begin late morning and early afternoon across the high country of southern New York and northern Pennsylvania. Those areas could see accumulating snow today with up to 6 inches in places.

The heavy snow will develop tonight across western New England into Maine. Those areas will see 1-6 inches of snow with some local amounts near 10 inches, especially across eastern Maine.

Above, the 3km NAM, maybe a little over done, shows the area where the heavy snow will occur.


HRRR model

The HRRR model through this evening is showing snow from northeast Pennsylvania into New England.

Keep in mind, this will be a wet snow and hard to shovel.

Watch the change to snow on radar.
