From here on the UVM campus I could see that snow started to fall in parts of the local Green Mountains as of ~3:15 P.M.; at that point it was visible crashing out of the clouds at Camel’s Hump.  As of 3:30 P.M. all the peaks of the spine from there south have disappeared behind the snow.  The snow appears to be moving north, but for now the peaks north of the Winooski/I-89/Route 2 corridor are still visible.

Summary:  0.7” snow total in Waterbury (495’) as of 6:00 P.M. EST

 

By roughly 3:45 P.M. the entirety of the Green Mountain spine that I can see from the UVM campus (roughly Lincoln Peak through to north of Mt. Mansfield) had disappeared behind snowfall, but the foothills were still visible.  It was right around 4:00 P.M. when I saw the initial flakes in my area of the UVM campus (380’).  When I next had a chance to look outside at around 4:45 P.M. I saw moderate snowfall driven by some strong south winds, and the snow was just starting to accumulate on the ground.  The snowfall had become less impressive by the time we hit the area of the Richmond exit for I-89 (300’) and stayed at that light intensity right through to Waterbury (~500’).  I suspect we were just outpacing the front edge of the snow however, since as I drove from the park and ride to the house, the snow seemed to be intensifying.  I used my odometer to get a distance measurement on the visibility, and it was around 0.20 – 0.25 miles, but it was also starting to get dark which could affect the visibility.  We had essentially a dusting of snow on the snowboard at around 5:40 P.M., but when I looked outside at 6:00 P.M. the snow was coming down furiously with a mixture of flakes sizes, some up to ~ 1 cm in diameter.  I went out and checked the snowboard and found 0.7 inches of accumulation as of 6:00 P.M., and the air temperature was 30.4 F.

At 11:00 P.M. last night there was about an additional inch of snow on the snowboard that had accumulated since the 9:00 P.M. clearing, and then another inch and a half fell on top of that between the 11:00 P.M. and 6:00 A.M. period.  Our temperature is right around the freezing mark down here in the valley, and the accumulated snow wasn’t too dense at 8.0% H2O, but it was still a bit clumpy when I cleared it off the board.  I suspect that’s a function of being so close to the freezing mark down at this elevation.  Light snow continues and there’s another four tenths of an inch on the board as of 7:00 A.M. I’ve added the usual north to south list of those Vermont resorts that have reported in their accumulations this morning:

 

Jay Peak:  6”

When I descended to the bottom of the Bolton Valley access road this morning and saw that the temperature was 35 F, I figured it likely that we’d go above freezing at the house as well.  I suspect we did, since this morning’s 0.6 inches of snow had settled down and become crusty on the snowboard.  I was still able to get core samples from it however, which revealed 0.03 inches of liquid.  When I left Burlington this evening the temperature was already down to 34 F, much lower than the 39 F I’d observed when I’d arrived in the morning.  I saw a few flakes in the air starting around the Williston exit of I-89, but that was all there was until about the Washington country line, where a steadier light snow had taken over.  We had very light snow here at the house until around 7:00 P.M. when it began to come down vigorously with some big flakes of 1 cm plus in diameter.  The heavier snow has been on and off, but I’ll try to take some intermediate accumulations measurements this evening to see how the snowfall progresses.  It seems that the BTV NWS is on top of the upslope potential with this event, as their point forecast for our location has us down for 3 to 7 additional inches of snow through Friday night.  The current snowfall has definitely got that upslope feel, so I suspect the mountains are doing well.  Intermediate snowfall accumulations are below:

 

6:00 P.M.: 0.0”

7:00 P.M.: 0.3”

Overall we've had moderate snowfall over the past hour, but lots of fluctuation between light and heavy intensity.

Some intermediate snowfall observations yesterday evening went as follows:

 

6:00 P.M.: 0.0”

7:00 P.M.: 0.3”

8:00 P.M.: 0.8”

9:00 P.M.: 1.0”

 

We had generally light to moderate snow yesterday evening, but it certainly felt like upslope.  Then at around midnight I noticed that the snowfall had really started cranking up, and I did a quick check to find ~2 inches on the snowboard.  This morning there was a total of 6.4 inches on the snowboard, and it is certainly Champlain Powder™ dry.  I could tell immediately when I walked through it and couldn’t feel it on my legs that the density was going to come in extremely low, and the numbers revealed that it is just 2.3 % H2O.  I’m anxious to see how hard the snowfall keeps up today, but in any event the skiing should be off the hook with this stuff on top of yesterday’s medium-weight powder.  Only a few resorts have sent their storm totals in to SkiVermont.com so far, but I’ve added them below:

 

Jay Peak:  18”

Stowe: 15”

When I arrived in Burlington this morning it appeared as though they’d picked up just a dusting of snow overnight, which was quite a contrast from Waterbury where we’d received more than half a foot.  During the morning in Burlington there wasn’t much going on, and I could even see the Green Mountains a bit in the early hours.  As the morning wore on however, I saw the snow move back into the mountains and they disappeared from sight.  In the late morning I saw the wall of white expand westward and engulf the foothills, and by around noon it actually started to snow in Burlington.  We had some bouts of heavy snow in Burlington in the afternoon, and the ground was covered with white.  I figured it had to be puking snow in the mountains if we were getting hit in Burlington.  When I left Burlington at around 7:00 P.M. or so, there was just some very light snow, but it gradually increased all the way through to Waterbury where it was snowing moderately.  We picked up another 0.15 inches of liquid equivalent with our snow today at the house, just as we did last night.  However, today’s flakes didn’t appear to be as big as last night’s and this snow accumulated to less than half the depth with the same amount of liquid.  As of 10:00 P.M. there’s another 1.3 inches of snow on the snowboard that has accumulated since the 8:00 P.M. clearing, so we’ve been running a bit over a half inch per hour for the past couple of hours.  The average flake size seems a bit bigger now than earlier this evening, so that is likely helping to boost the accumulation.  As of that latest reading, this is officially our largest snowfall event of the season so far at 14.6 inches and counting.  The 14.2-inch event from November 20-23 has now been pushed to second place.  Up in the local mountains they were approaching the two foot mark with this event as of this evening, and the Northern Vermont resorts should easily be past that point by tomorrow morning.  Here are the latest accumulations I’ve seen for the Vermont resorts along the spine, listed north to south:

 

Jay Peak:  23” (7:00 P.M.)

Smugg’s:  20” (4:56 P.M.)

Stowe: 15” (2:30 P.M.)

Bolton:  23” (8:15 P.M.)

Mad River: 19” (3:30 P.M.)

Sugarbush: 17” (1:35 P.M.)

Pico:  15” (4:00 P.M.)

Killington: 15” (3:00 P.M.)

Okemo: 11” (2:49 P.M.)

Bromley: 14” (6:00 A.M.)

Magic: 13” (6:00 A.M.)

Stratton:  12” (2:31 P.M.)

Mount Snow: 7” (6:00 A.M.)

The snow appeared to slow down pretty quickly after about midnight last night here in the lower elevations, but it looks up on the hill they did pretty well with another foot overnight at Bolton Valley.  That brings the resort to three feet of accumulation from this event.  We’ve still got light snow falling so there might be a touch more snow to report for this event before moving on to the next one.  I’ve added the updated storm totals for the resorts on the Green Mountain spine, which are listed from north to south below:

 

Jay Peak:  25”

Smugg’s:  23”
