At UVM in Burlington today (elevation ~380’) it looked like snow started to mix in with the rain at some point between 2:00 and 3:00 P.M., but the precipitation was very showery in nature and seemed to stay mostly liquid.  However, when I was outside later catching a bus back to Waterbury at around 5:20 P.M., the precipitation had changed over to entirely snow.  It was still very light in nature and not accumulating, but the atmosphere was clearly cold enough to produce all snow.  Later on the bus I working on something and had essentially forgotten about the snow until my peripheral vision caught a glimpse of something bright outside the window.  I looked out to see pounding snow and accumulations on the ground.  At that point I was in the slightly higher elevations of the Williston area along I-89 (600’-700’) and boy was it coming down hard.  As we descended French Hill into Richmond, the snowfall stopped quickly and the land was back to bare grass.  I expected it might pick up again as I headed farther into the mountains, but it only came back to light intensity and there were no accumulations all the way through to Waterbury.  We’ve had some light snow here in Waterbury this evening, but nothing resulting in any accumulation.

In Waterbury (495’) we had plenty of light snow and flurries in the air yesterday and overnight, but picked up just barely a coating on some surfaces.  I did find a couple tenths of an inch on the snowboard this morning when I measured.  Consistent with what I’d seen on the way home yesterday, and in a reversal of what often happens around here, I found that accumulations of snow actually increased a bit as I headed west toward Burlington this morning.  At the bottom of the Bolton Valley access road (340’) there was a slightly more substantial dusting than what we’d picked up at the house, but that increased (quite slowly though) as I went up in elevation.  Temperatures in the low to mid 30s in the Winooski Valley dropped to 25 F at the Bolton Valley Village (2,100’) and here’s what I found for new snow accumulations with regard to elevation.

 

2,100’:  1 - 2”

2,500’:  2 - 3”

2,600’: 

2,800’:  3 - 4”

3,150’:  4 - 5”

 

The accumulations were topped off with notably drier snow than our March/April storms of the past few weeks, with what I’d guess was 6-8% H2O fluff on top.  When I headed back down the access road at around 8:30 A.M., the temperature at the base of the road was 34 F.  There was light snow on and off on the route to Burlington, and through all the valleys the most notable accumulation was in that high elevation area of Williston (600-700’) where I’d seen heavy snowfall on Tuesday afternoon.  There was about an inch of snow on the ground there.  We had light snow at times in Burlington during the day and we’ve had the same stuff here in Waterbury this evening, but I haven’t seen any accumulation in either location.

Thursday

 

I could see from Burlington that additional snow was falling yesterday, so I stopped up at the mountain again this morning to check it out.  There was no substantial accumulation that I could see in any of the valleys, but below is what I found this morning up at Bolton Valley.  The first depth is what I found yesterday morning, and the updated depths follow:

 

2,100’:  1 - 2”  ΰ  2 – 3”

2,500’:  2 - 3”  ΰ 

2,600’:         ΰ 

2,800’:  3 - 4”  ΰ  5 - 6”

3,150’:  4 - 5”  ΰ  6”+

 

Overall it looks like about another inch or two fell, but it was again nearly mid-winter density fluff at probably 6-8% H2O and you can tell by the way it sparkles in the sunlight that it’s quality stuff.  The temperature was around 30 F at the base when I arrived, and somewhere in the 20s F up at the top.  The sun was out, with clearer skies off to the north and more overcast to the south.  The turns are bottomless and dreamy up high thanks to the gradient of powder that has been set down, but I’m not sure if the snow will stay fluffy in the middle elevations with the sun and temperatures today, so it’s best to get at it sooner rather than later.
