Update: Some Scattered Damage From Wind, And Vermont Weekend Snow Update

Water droplets glisten on a spruce tree in St. Albans,
Vermont just before sunset as skies cleared briefly
behind a strong weather front. 
 Today's storm behaved pretty much as expected, leaving behind power outages here and there, downed trees and a few reports of flooding in southeastern Vermont and in New Hampshire. 

Peak winds reported included 52 mph in East Berkshire, 47 mph in Underhill and 45 mph in Jeffersonville. All these areas are along the western slopes of the Green Mountains, and are prone to winds in this morning's type of weather situation.

Based on a few scattered damage reports that came in, there were probably very localized areas were downslope winds were even stronger than the reports above. One large tree and four small ones came down along North Cambridge Road in Cambridge.  There were also tree limb and power line issues in Underhill.  A tree and wires were reported down in Springfield, as well. 

The number of power outages in Vermont was dwindling as winds calmed down amid the rains that came with the storm's weather front. More than 6,000 homes and business were without power in the Green Mountain State this morning, but by mid-afternoon, that number was down to about 2,000.

Some of the rain with the front was pretty heavy, especially in southeastern Vermont and on into New Hampshire and southern New England. A flood advisory was up for far southeastern Vermont for much of the afternoon.

The big parent storm still over the Great Lakes has what is known as a "dry slot" which is pretty typical of these large, lumbering November storms.  A dry slot is a narrow punch of dry air immediately behind the storm's cold front.

Once the front goes through, those dry slots can result in very quick clearing, which is what happened late this afternoon in western Vermont.  Nice sunset! 

SATURDAY SNOW AND BEYOND

The people that run mountain ski areas are going to like the next few days. It'll be generally cold enough to make snow, and in the high elevations, several modest but accumulating snowfalls are in the offing. 

The first storm, which I mentioned this morning, is going to be rather small, but quick moving and very dynamic. That means we'll get a burst of rain, with likely measurable snow at elevations above 1,000 feet.  Mountain peaks could get two to five inches of snow.

This will be a short-lived event, but rather exciting while it's here. Rain will quickly change to snow down to 1,000 feet Saturday evening, and a few flakes or even a brief slushy accumulation could hit the valleys. 

Another system comes through Monday with another few inches of snow for the peaks and minor accumulations at mid-elevations.  More wet snowflakes look like a good bet in the valleys. 

At this point, Monday night and Tuesday morning look cold enough to produce possibly light, but measurable accumulations of snow all the way down into the valleys. We'll see!
