Today’s Northeast weather discussion…

A strengthening clipper storm is tracking north of the Great Lakes, with a warm front approaching. The warm front will continue to lift through the region tonight. The warm front will allow temperatures to warm a bit, but breezy conditions will still make it feel chilly. A strong arctic cold front will move through the region during the overnight and Thursday. Temperatures will quickly plumet leading to a flash freeze during the afternoon and evening.

Updated snow amounts.

Light to moderate snow showers and a few snow squalls will bring a trace to a few inches of snow, with the highest amounts nearer the Great Lakes where 6-14+ inches of snow will be possible.

As far as general snowfall amounts for late Wednesday through Thursday.

Along the northern tier of Pennsylvania 2-5 inches, with northwest Pennsylvania seeing 6-14 inches. Southwest Pennsylvania could see 1-2 inches of snow, with the higher terrain East of Pittsburgh and Western Maryland seeing 3-6 inches with the highest peaks seeing 6-8 inches. Western, Central and Northern New York State look to see a general 4-8 inches, with those closer to Lake Ontario (on and near the Tug Hill) seeing 6-14+inches. The Adirondacks will see 5-12 inches with locally higher amounts possible, Catskills into the Poconos look to see 3-6 inches, with the higher peaks seeing 5-8 inches. 

Around Syracuse, the Mohawk Valley into Southeast New York State north and west on New York City and East of the Hudson Valley 2-4 inches looks likely, The hills south of Syracuse and the Mohawk Valley a general 3-6 with locally higher amounts. Those in Hudson and Champlain Valleys look to see a general T-3 inches.

Most of Vermont, New Hampshire and Maine look to see 2-6 inches, with a bit more for west central Maine. Northern Maine looks to see 6-12 inches. The Greens and Whites could pick up 6-14 + inches. Western Massachusetts looks to see a general 3-6 inches, with the Berkshires 4-8 inches.  Central into Northeast Massachusetts and Southern Maine seeing 1-3 inches. The Coast of Maine, a T-2 inches. Much of Connecticut looks to see 1-2 maybe 3 inches in spots.

Much of eastern (including Boston) and Southeast Massachusetts, Southeast Connecticut, Rhode Island, New York City and Long Island, southeast Pennsylvania (Including Philadelphia) most of New Jersey and Eastern Maryland and Delaware look to stay mainly rain but there could be a bit of snow, generally a T to less than an inch is possible

Southern New Jersey down into Baltimore and Washington DC no snow is expected.

With the arctic front general winds of 10-30 mph, with gust of 40-60 mph possible.

All of this will cause travel nightmares Wednesday night and Thursday.

The coldest air of the season so far will drop down into the Eastern US, with temperatures of mid to low 30’s possible as far south as mid Florida. Up here temperatures will be 20-30 degrees below average for this time of year. The cold air moving over the Great Lakes will cause more lake effect snow bands, but the snow shouldn’t be anything like we just saw.

For Friday winds will still be gusty, a few troughs will work through bringing a chance for snow showers and flurries. There could be a few lake squalls near the great Lakes.

Saturday will see more troughs work through keeping things unsettled. The good news is winds won’t be as gusty, and temperatures will be warming to seasonal levels.

Sunday will see high pressure overhead, providing nicer weather. The high will move south and east on Monday as a cold front approaches, ahead of the front a southwest flow, will allow our temperatures to climb. As the cold front comes through most of us should see rain, with the higher elevations and areas with a deeper snowpack seeing a mix.

As we approach mid-month, temperatures should be milder. Then during the 2^nd half of the month into January the pattern looks to return to what we’ve been seeing the last couple of weeks.
