Monday Evening Nor'easter Update: Still A Blast East, Vermont Updates

While eastern New England gets blasted by blizzard
and near blizzard conditions Tuesday, the nor'easter
will cause a long-duration, light snow event in
Vermont. Expect five to 10 inches most places
from early tomorrow morning into Wednesday.
More relatively light accumulations will add
to the total late Wednesday through Thursday. 
Just a quick Monday evening nor'easter update: Steady as she goes with the general forecast for the latest nor'easter that's coming in late tonight and especially tomorrow.

Here are the principal changes:

Along the immediate southern New England coast: Winter storm warnings have been upgraded to blizzard warnings.

The combination of snowfall rates of one to three inches per hour combined with winds gusting as high as 65 mph will cause some blizzard conditions.

As I said this morning DO NOT drive to places like Boston, Portland, Maine or Providence Rhode Island tonight or tomorrow.

Travel will basically be impossible in that neck of the woods. The worst of it there will be Tuesday morning into early afternoon, but it will be scary all day.

Most of eastern Massachusetts, New Hampshire and Maine can expect 12 to 18 inches of new snow out of this, with local amounts up to two feet.

More coastal flooding and damage seems likely along the Massachusetts coast, especially during the Tuesday morning high tide. Astronomical tides aren't big this week, but the strength of this big nor'easter will still cause big problems, especially since the coast is so vulnerable from the damage left by the previous two nor'easters.

Most of Vermont continues to look like it will be on the western edge of this storm. Steady snow will develop south to north and continue all day Tuesday. It won't snow all that hard in most places, but this will last quite a long time -- lasting into Wednesday.

Generally speaking, most of Vermont will get six to ten inches of new snow between early tomorrow morning and Wednesday morning. Most of the time, the snow will come down lightly, so for most of the state, a winter weather advisory will do. Somewhat more dire winter storm warnings don't seem like they are needed, except in far southern Vermont, where snowfall Tuesday will be a little heavier.

Light snow will continue through Thursday, especially in the north and mountains of Vermont, which will mean additional accumulations. It will be somewhat colder than last week, so don't expect much melting during the days like the warmer valleys experienced last week.

No real thawing is expected until at least Sunday.
