Yet MORE Snow, Especially Northern Vermont, Later Today, Tonight

As expected, snow squalls developed in many areas of
Vermont and surrounding states Friday. I encountered
this one as I left work in Burlington, Vermont late
Friday afternoon. 
For those of you in Vermont, particularly northern sections, you might have woken up this morning to at least patches of blue sky. The days long period of almost continuous snow accumulation is over, right?  

Wrong. Totally wrong. Especially if you live in the northern Green Mountains.

That decaying nor'easter that's lingered in southeastern Quebec and northern Maine is still hanging around.

Another wave of moisture is rotating around this system. And the wind is orienting itself to bring an upslope snowfall to parts of northern New York and especially the central and northern Green Mountains.

An upslope snow is when moist winds rise up and over the mountains. When the air rises like that, the moisture gets wrung out as precipitation, in this case, snow.

This scenario has been contemplated for days, as varying forecasts over the past few days either said the northern mountains would get a huge dump with this, or hardly anything at all.

It turns out this will be a relatively small dump for most areas of the central and northern Green Mountains, with some areas doing quite well, especially up near Jay Peak.  All this is enough snow to qualify for a winter weather advisory for far northern Vermont away from Lake Champlain.  

There's going to be a sharp gradient in new snowfall between Lake Champlain and the northern Greens. On the lakeshore, there will probably be only a dusting. By the time you get into towns along the western slopes like Underhill, Cambridge, Bakersfield, parts of Enosburg, that kind of thing, we're talking four to eight inches of new snow by Sunday morning.

Parts of the high elevations of the Northeast Kingdom, places like Walden, Sutton, Sheffield, will also probably get a lot of snow out of this.

Some favored mountain peaks could get as much as a foot. Yeah, I'm looking at you, Jay Peak.

Parts of the Adirondacks will probably get a few inches of snow, too.

The far southern Green Mountains, where three feet of snow fell Wednesday night, will probably only get a couple inches of new snow out of this.

On Friday, snow squalls developed across New York State, parts of Vermont and southern New England as expected. Nobody got huge amounts of new snow, which was predicted. But a few places picked up a few inches, especially in the mountains.

Burlington, Vermont, which hasn't exactly gotten the most snow of anybody so far this month, is still running ahead of normal for snowfall for March so far. There's been 13.6 inches of snow so far this month, which is nearly eight inches above normal.

Snowfall for the season, after falling below normal during the record warm second half of February, is back to a bit above normal for this point in the season in Burlington. They've gotten 68 inches since the start of winter.

A little more snow is coming there, too. Burlington should get a bit of snow out of this tonight.

Next week, it's still looking like that nor'easter will miss us (but we'll keep an eye on it anyway because it's still possible it could veer toward the west and affect us.) But regardless, the weather pattern still favors lots of snow showers next Tuesday, Wednesday and Thursday.
