Here in Burlington, I’d seen the occasional flake in the air since mid morning, but around 12:30 P.M. was when the continuous snow started to fall.  Flakes were very small at first, but then became much larger (up to 1 cm) and the intensity increased.  About an hour ago it started accumulating on some surfaces, although the accumulation is still just a dusting.  The snowfall has slowed down in the past 15-20 minutes but it’s still falling steadily.



As of ~5:00 P.M. in Burlington there is a fluffy ¼ to perhaps ½ inch of snow accumulation, and the snow is sticking on all surfaces.  The flakes are fairly large (up to ¾ inch diameter) and there is no wind so it’s been fun watching them fall.  The Greens have been hidden in snow since earlier today, but I’m heading home now so I’ll see how accumulations are going in the mountain towns.



Event totals: 1.1” Snow/0.05” L.E.

Tuesday 1/4/2011 6:00 P.M. update:  In the center of
Waterbury I found roughly double the amount of new snow that I’d seen in Burlington, and at the house I found 1.1 new inches on the snowboard.  At that point the snow was falling very lightly, but around 7:00 P.M. it started falling much harder with big flakes up to an inch in diameter, and as of 8:00 P.M. there was nearly another inch on the board.  So the snow has been falling at close to an inch per hour due to the big flakes.  Looking at the radar, this more intense snow seems to be associated with the big slug of moisture heading eastward from the Champlain Valley:



In terms of seasonal milestones, we did pass 50 inches of snowfall with this event, although we are still about 15 inches behind average based on my data.  Hopefully this week will help us catch up, but it will be difficult because by Sunday the seasonal snowfall average is at almost 71 inches.

Some details from the 6:00 P.M. observations are below:

New Snow: 1.1 inches
New Liquid: 0.05 inches
Snow/Water Ratio: 22.0
Snow Density: 4.5%
Temperature: 25.7 F
Sky: Light Snow (1-3 mm flakes)
Snow at the stake: 5.5 inches

Event totals: 3.0” Snow/0.09” L.E.


Wednesday 1/5/2011 6:00 A.M. update:  The biggest six-hour period for snowfall with this event so far at our location was the 6 P.M. to midnight block last night, where 1.4 inches fell, and then an additional 0.5 inches fell between midnight and 6:00 A.M.  The intensity of the snow had picked up as I was taking the 6:00 A.M. measurements, and in his early broadcast Roger Hill said that we were in the midst of another flare up; there was actually another tenth of an inch or two of snow on the board by the time I was leaving the house:


Burlington picked up some additional snow overnight as well; here on the UVM campus it looks like the event total is about an inch.  Below are some of the storm totals I’ve seen reported by the Vermont ski areas along the spine as of this morning, listed north to south:


Jay Peak: 3”

Smuggler’s Notch: 2”

Stowe: 5”

Bolton Valley: 5”

Mad River Glen: 6”

Sugarbush: 4”

Killington: 3”

Some details from the midnight and 6:00 A.M. observations are below:

1/5/11 12:00 A.M.
New Snow: 1.4 inches
New Liquid: 0.03 inches
Snow/Water Ratio: 46.7
Snow Density: 2.1%
Temperature: 27.1 F
Sky: Light Snow (2-10 mm flakes)
Snow at the stake: 6.5 inches


1/5/11 6:00 A.M.
New Snow: 0.5 inches
New Liquid: 0.01 inches
Snow/Water Ratio: 50.0
Snow Density: 2.0%
Temperature: 25.3 F
Sky: Light Snow (2-5 mm flakes)
Snow at the stake: 6.5 inches



Event totals: 5.0” Snow/0.18” L.E.


Wednesday 1/5/2011 6:00 P.M. update:  It was snowing pretty hard when I left the house this morning, and it even snowed in Burlington today to add to their accumulation, so I was curious to see how much snow we picked up at our place.  When I arrived at my car in Waterbury it looked like at least another inch of snow had fallen on it during the day, and when I reached our driveway I was quite surprised to see that my wife’s tire tracks looked like they had gone through about a half a foot of new fluff.  It wasn’t quite six inches, but I did find another 2.0 inches on the snowboard, bringing the event total to an even 5.0 inches.  It didn’t seem like this clipper was going to be all that strong, but 5 inches is certainly a decent accumulation so perhaps there will be some progress in catching up to our snowfall average this week.  My wife said that it snowed nicely all day in Morrisville and they have similar accumulations to what we’ve got here at the house.  Up above us, Bolton Valley was reporting 5 inches of new snow as of early morning, so I’d think they would have picked up more today, but I haven’t seen an evening update yet.  They were dropping ropes on additional trails today thanks to the new snow though.  Some details from the 6:00 P.M. observations are below:

New Snow: 2.0 inches
New Liquid: 0.09 inches
Snow/Water Ratio: 22.2
Snow Density: 4.5%
Temperature: 23.4 F
Sky: An occasional flurry
Snow at the stake: 7.5 inches

Event totals: 5.5” Snow/0.18” L.E.


Thursday 1/6/2011 6:00 A.M. update:  We picked up another half inch of very fluffy snow overnight to add to the snowfall total.  Even as of yesterday however, this clipper was already our third largest snowfall event of the season.  Since yesterday, the mountains picked up additional snowfall as well, so I’ve updated the storm totals for the mountains along the spine, listed north to south:


Jay Peak: 19”

Smuggler’s Notch: 6”

Stowe: 9”

Bolton Valley: 5”

Mad River Glen: 4”

Sugarbush: 10”

Killington: 3”


The numbers are quite variable along the spine, with some areas getting close to a foot now, but Jay Peak has clearly ramped up its legendary snowfall magic in a way I hadn’t seen yet this season to lead the pack.


In his morning broadcast, Roger Hill said that he’s not expecting much accumulating snow in our area in the Thursday-Friday timeframe, but for Saturday-Sunday he was going with 4 to 8 or perhaps 5 to 10 inches for the mountains.  Presumably we’d get in on a portion of that in the mountain valleys


Some details from the 6:00 A.M. observations are below:

New Snow: 0.5 inches
New Liquid: <0.01 inches
Temperature: 15.6 F
Sky: clear
Snow at the stake: 7.5 inches

Jay Peak coop, which I believe is at the base of the mountain, came in at only 5"....0.22" of liquid.


Checking the Jay Peak Cooperative Observer Site has seemed to be the best way to get an independent look at the Jay Peak numbers.  One never knows for sure if something different went on near the summit since the coop is at the base, but when the coop and ski area numbers are the same, that is a nice confirmation.  Checking out the recent reports from the coop I found:


1/3/2011: New: 0”, Total Depth: 8”

1/4/2011: New: N/A, Total Depth: N/A

1/5/2011: New: 2”, Total Depth: 10”

1/5/2011: New: 5”, Total Depth: 14”


That would suggest 7” of new snow and a 6” increase in snowpack depth, which seems like a reasonable combination if they’re just doing 24-hour measurements.  I wonder if borderwx from up in Newport Center has any first hand observations from the recent snowfall at the mountain.

Where did the 19" come from? Snow report at http://jaypeakresort.com/ says 8-10" last 24hr as of 7am

Bob- their website said 19 inches in 48 hours this morning.
It's since been reduced to 13 inches in the past 24 hours (which as we can see by the Jay Coop is still a little off). Anyway...you can read about it here
and here.


Following up with what adk has above, it looks like it was either a preliminary report or an error as borderwx suggested; nice to see that they corrected it.  On the latest version of the page, the 19” for 48-hour (what I was considering the storm total) and 7-day totals has been replaced with 13”:



It’s still not exactly in line with the Cooperative Observer Site data, but with a couple thousand feet of elevation thrown in, 13” seems a bit more in line than 19”.


Snowfall update from today:  Here in Burlington it actually snowed steadily for a while in the morning, but there was no accumulation in this area.  The snow that is on the ground here actually looks like it saw some melting today, or perhaps it was just the fluff settling and revealing some spots of grass.  In the mountains the snowfall was more consistent and now that the sun is coming out there is a distinct line visible around the 2,000’ elevation mark with everything above quite white (image below).  I’d guess that there was a little more accumulation in the higher elevations today.
