Forecast Discussion

Well, boy did things change with this forecast. Without getting too complicated, the simple answer is that EVERYTHING was pushed further South, and East. For a more technical answer, see below.

Final snow accumulations map. Best chance for 1-2″+ will be in NE PA, Cape Cod, parts of W NY and possible far NW NJ around here.

Technical reason why this went boom…the UL…it went South. Why? Because the blocking to the N of us did not budge, and the models incorrectly assumed that it would boot out of here, allowing the UL to then elongate further N. It will still Elongate, but it will be much further S. When looking at the map above, the W side will be from the warm advection snow as the UL passes to our West and we get some energy. The East snows (SE MA, Cape Cod) will be from the coastal low as it ramps up, but again, well to our South and East.

Parts of the Mid Atlantic could see some severe weather with this, but for us – clouds and flurries/snow shower maybe some light snow and a trace to coating at best.

Quick word on the upcoming week. We start out a bit warmer Monday and Tuesday, and then quickly change to much colder as colder weather comes in by Tuesday/Wednesday:

Have a great day!
