We were at Stowe today and it snowed the whole time on the mountain. It was generally light, but it just didnít want to stop as Powderfreak said, so there were always big flakes in the air and it was quite a December scene. It wasnít a huge dump, but even the few inches of fresh snow were enough to get folks pretty jazzed up. Iíll put up a couple of pictures later.


I put together a few pictures below from yesterday at Stowe.  It was really great to get that surprise snow Ė it wasnít a huge dump, but I had some really nice powder turns on our first run off the quad, and at least on the top half of the mountain I found that the new snow really enhanced the conditions for a while.  Iíve got the full report from yesterday at our website.


I was also just looking at the 12Z ECMWF, and saw that there were four upcoming chances for winter weather on there: Monday, Wednesday, Friday, and Sunday/Monday.  None looked huge, but thatís nice heading toward the holiday week.  It sounds like the Wednesday event could be a bit messy though with regard to the frozen precipitation based on the BTV discussion.

Thanks for the discussion highlights PF; it should be fun to see how it plays out.† As I was setting up a new text file and putting in the date for logging this next potential snow event, I realized that itís actually only been two days since our last snowfall.† It would be nice for the slopes to get into one of those regimes where the Greens provide a little something every couple of days; even though they arenít typically blockbusters, that positive reinforcement would be great for the snowpack.† If Mother Nature should want to sprinkle any bigger snow events in there that would of course be OK as well.

BTV WRF model showing how localized we can expect the snow in a 12 hour period later today.

This would imply several inches at work and a dusting at home a few miles down the road. J.Spin is smack in the middle of the 0.25-0.5 QPF where it goes down the spine so he may do well (not all that surprising, lol). Note Jay Peak up there with 0.5-0.75" of QPF... that would be pretty nuts given good snow growth and falling in like an 8 hour period.


I took a look at the 3-hour BTV WRF intervals and you can watch the precipitation walk right down the spine from 2100 hrs today through 0900 hrs tomorrow (is that all in Z, so 4:00 P.M. today through 4:00 A.M. tomorrow?).† Anyway, that would be pretty decent timing for Tuesday morning turns.

A couple flurries falling now.


Yeah, from here at UVM I can see the clouds really dropping to right around the peaks and caps were forming on Mansfield, Bolton, Camelís Hump, and a long one on the Stark through Abraham stretch.

In other news... the BTV WRF model now thinks that both Jay Peak and Mansfield see 0.5-0.75" of QPF tonight in the form of upslope snow.


I eventually figured out how to zoom in on the BTV WRF so I could see a little more detail, so that has been helpful.



Thus far weíve just had light rain this evening down here in the valley, but frozen precipitation started mixing in here at ~9:50 P.M., and the precipitation has recently fallen more intensely.† Itís just been some sleet at this point though, as weíre still fairly warm (38.7 F) at this elevation.† Iíd say the mountains must be getting hit with snow though, since the Mt. Mansfield real-time temperature at 3,950í is at 26 F, and even down at 2,100í the Bolton Valley Weather Station is below freezing at 31.2 F.

Event totals: 0.1Ē Snow/0.09Ē L.E.


At ~9:50 P.M. last night, frozen precipitation in the form of sleet started to mix into the rain, and by ~10:30 P.M. the temperature was down to ~35 F and snow was mixing in.† The precipitation must have shut off pretty quickly though because there was just a tenth of an inch down on the snowboard this morning, and that may have come from the light snow thatís currently falling.


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


New Snow: 0.1 inches

New Liquid: 0.09 inches

Temperature: 26.4 F

Sky: Light Snow (2-8 mm flakes)

Snow at the stake: Trace
