Winter Storm to Impact Interior Northeast

So far, this year has seen a pretty fast start to snowfall. Close to home, Louisville is much above average in terms of snowfall, and even here in Bowling Green we have received snowfall. Well, in parts of the Northeast, they have already seen their fair share.

In Buffalo, they had the epic and now infamous lake-effect snow event in mid-November. In parts of New England and the interior northeast, they had a pretty substantial pre-thanksgiving snow event, with many areas seeing up to a foot of snow. Now, parts of the northeast are preparing for another significant winter storm. Oh, and also, winter hasn’t even begun.

Late last week the ECMWF caught onto a weird idea that a low pressure system would take a northwestward track out of the Atlantic, deepen, and sort of stall over the northeast. Well, this solution looks like it is actually going to verify.

Within the large scale pattern, there is a strong low pressure system residing over Greenland, and a piece of cutoff energy within the west-central Atlantic. What will happen is the piece of energy that is gonna give our temps a dive overnight and into tomorrow is gonna pull the energy back into it and force surface cyclogenesis across the mid atlantic.

This will spread deeper moisture across interior portions of New England, and while most areas will have to overcome some initial warmer air, the low should be able to draw enough cold air into the system to produce snowfall. Several NWS offices are expecting significant snowfall accumulations from this system.

 

 

 

One of the interesting signals that the models are showing with this system is the idea that it cuts off, and sits over the same areas for several days. This would keep our temperatures cool locally as we’d be within a north to northeasterly flow off of this system. For even more info on this storm, check out these NWS offices:
