Yet Another Overperforming Snowstorm Socking Vermont, Surrounding Areas

A long line of cars slogs through heavy, wet snow at Exit 19 of
Interstate 89 in St. Albans late this afternoon. 
Well, this is certainly turning into a doozy of a snowstorm for Vermont and adjacent areas, isn't it.

The first half of the storm, roughly into early afternoon, really hit east facing slopes of the Green Mountains.

Some areas definitely got more snow than expected. Some examples: Marshfield reported 16 inches, Walden, 15 inches, Moretown, 14 inches.

That's a lot of snow.

While it is still snowing along those eastern slopes, it's coming down lighter now. And it probably won't get particularly heavy in those places overnight.

There will be more accumulation there, but it won't pile up nearly as fast as it did earlier today.  The mountain summits, which got tons of snow the first half of today, will continue to pile it up fast, so we'll see some pretty amazing totals up there.

We're now in the second half of the snowstorm,  The wind has shifted and increased from the north and northwest, so it's the western slopes of the Green Mountains that are getting clobbered. Road conditions deteriorated fast late this afternoon in the Champlain Valley as the snow finally started to accumulate.

For several hours at least this evening, the snow will come down at a good clip even in the Champlain Valley. Elevation will still be a factor:

Forecasters think totals will range from as little as three inches along the immediate shore of Lake Champlain, to six inches or so a few hundred feet higher in elevation and a few miles inland from the lake, to a foot or more along the western slopes well east of Burlington -- towns like Underhill, Jericho, Huntington, Bakersfield, East Enosburg, all those types of places.

These are storm totals, taking into account what already fell plus what's expected to accumulate.

Who knows, the way this storm has been behaving, there might be more surprises with even deeper snow in these communities. After all, right along the western slopes, most forecasters think the snow will keep going into Saturday morning.

Winter storm warning have been extended westward to include all of Franklin and Chittenden Counties.

Basically, don't travel anywhere tonight. Also postpone travel until Saturday afternoon, when things will have definitely improved.

It's been bad enough all day. NECN reports roughly 100 crashes and slide offs in Vermont during the day. This includes a fatal crash on Vermont 22A and several multi-vehicle pileups. Interstate 89 near Montpelier was impassable for a time due to crashes.

Power failures with the heavy, wet snow have been a problem in some areas all day. At last check, around 6 p.m. there were about 1,250 homes and businessses without power across Vermont.

I have a feeling these numbers will go up through the evening as the heavy wet snow really starts to pile up in populated areas of Franklin, Chittenden and Addison counties. Gusty winds now blowing aren't helping. If anything, those winds will increase overnight.

At least the snow will turn more powdery as we go through the night, so the chances of further heavy, wet accumulations will go down.

It's still supposed to be cold Saturday. After a mild-ish Sunday, it will be cold again Monday and Tuesday. The late week still promises to turn at least somewhat warmer. Long range forecasts are iffy, but many forecasters are dangling the prospect of highs in the 50s a week from today.

I'll believe it when I see it.
