Today’s
Northeast weather discussion…
High pressure is overhead for now
Our storm is
developing in the Midwest. The storm is going to be a quick moving system, so
it will move out of the Ohio Valley and quickly head for the Middle Atlantic
region.
Thursday is
going to be wet and snowy for some. Rain will be heavy at times. So, plan for a
slower go and possibly traffic delays. So, allow plenty of time to get to where
you’re going.
General snowfall
amounts
Snow will be
elevational dependent, with the heaviest snow over areas that are above 1500
feet. Along the twin tiers of New York
State up over southern Vermont, across New Hampshire into western and central Maine
4-8 inches of snow is possible, the higher elevations of the Pocono’s, Catskills,
Greens, and Whites look to see 8-12+ inches. Northwest Connecticut could see a trace to 2
inches. Much of western Massachusetts
looks to see 2-4 inches with the Berkshires seeing 4-6 inches.
The Appalachians,
areas north and east of Pittsburgh up through central Pennsylvania, a mix is
likely with snow looking to be maybe 1- 4 inches.
North of the
I-90 across much of northern New York State 2-5 inches with the Adirondacks seeing
4-10 inches. Along the shores of Lake Ontario, back through Syracuse, Mohawk
Valley and central and southern Hudson Valley a trace to a couple of inches.
For
Maryland, Delaware along the I-95 corridor up through NYC most of Connecticut, Rhode
Island, Southeast Massachusetts
up through Boston this should be primarily a cold rain event.
For those
going to the parades in the major cities, it will be rainy and chilly, so dress
for the weather. Winds shouldn’t be too bad during the morning, but they will
be increasing during the afternoon.
For Black Friday, it looks to be generally dry with just lingering rain/snow showers. But it will be a different story for those near the Great Lakes.
An upper-level
low overhead will have shortwave troughs rotate around it. The arctic air mass
moving over the warmer waters of the Great Lakes will kick off significant lake
effect snow bands. These snow bands will be meandering a bit for Friday into
Sunday east of Lake Erie and Lake Ontario. Downwind of the Great Lakes several
inches of snow will be falling, this will be especially true for the Chautauqua
Ridge and Tug Hill Plateau, those under the most persistent lake bands will be
dealing with a general 2-4 feet of snow, with localized higher amounts
possible. For Sunday night into Monday the flow will allow the bands to drop
south and east of the Lakes.
The pattern is going to support several waves of polar/arctic air intrusions along with Clippers dropping out of Canada over the next few weeks. With the overall patten looking to be cold over the next 2 to 3 weeks, there will be more snow chances.
Of course
there will be no post tomorrow.
