Monday, November 17th, 2008:  Vermontweather update

 

I’m not sure how muchsnowMt.Mansfieldpicked up from yesterday’s activity, but there is a newly-visible snow line at around 3,000’ this morning.  In the valley we were mostly clear this morning so the most I’ve seen there were a few flurries when I was leaving the house inWaterbury.

Last night I was heading back fromBurlingtontoWaterbury, noting the presence of stars and eventually the moon through broken clouds, so I was surprised when I was passing through the French Hill area in Williston and was hit by a brief period of snowfall.  That’s all I saw for precipitation on that trip however.  This morning I woke up to find that we’d accumulated some snow at the house though, so I took my usual collection of readings.  I got a call from my wife at around 6:30 A.M. and she alerted me that the exit 7 through 10 region (Waterbury-Montpelier) of I-89 was closed to traffic due to snow/ice on the road and some accidents, and I soon heard the same news on the radio.  There were no traffic problems on Route 2 in my direction towardBurlington, but there certainly was snowfall and accumulation.  I left the house at around 7:00 A.M. amidst light snowfall composed of snowflakes in the 1-3 mm range and a lot of graupel, and as I passed throughBoltonit intensified to moderate and the graupel on the windshield was making quite a racket.  The road was really covered with snow and the visibility dropped, and these two factors together made the driving a little more difficult.  Through Jonesville andRichmondthe snowfall was generally light with occasional bursts of moderate intensity, and the composition of the snowfall had changed.  There was no obvious graupel, and some of the snowflakes were notably larger, perhaps 5-7 mm in diameter at the high end.  It appeared as though the snowfall was tapering off as I passed through the very center ofRichmond, but as soon as I passed to the west of town the snowfall re-intensified to moderate.  Visibility was again difficult with the heavier snowfall in the form of larger flakes, and it stayed this way onto I-89 and up to the top of French Hill where things finally started to taper off.  In theBurlingtonarea it’s been snowing lightly/flurrying, but not with the intensity that I saw out in the foothills and mountain areas.  Throughout my route, I saw snow accumulations up to perhaps an inch, with generally just a skiff of snow inBurlingtonproper, and the temperatures were consistently in the 28-29 F range.

It snowed much of the day inBurlington, at least some of it due to theLake Champlaineffect, and when I left in the evening the accumulations appeared to be around an inch.  I stopped in at Taft Corners in Williston, where I’d say they had a more substantial coating that was probably close to 2 inches.  The consistent covering of snow was retained until about the center ofRichmond, where it really started to taper off quickly.  By the time I got toWaterburythere was almost no accumulation, with just a dusting left on our lawn and 1/10 of an inch on the snowboard.  Coming from the north, my wife said that there was an inch or two of accumulation in Morrisville, and it tapered off aroundWaterbury, so it appears as though the Waterbury/Bolton/Jonesville area was in between some of the more substantial upslope and lake effect snows.  Below, I’ve added a few of the mountain accumulations I’ve seen reported for this event.
