Anybody have any data wrt moisture content? With this wind the snow will likely end up in the woods.

I’ll run a liquid analysis when I do the 6:00 P.M. snowboard clearing, but judging by feel right now I’d go in the 6-8% H2O range down here with little to no wind. Flakes aren’t that big right now (2-5 mm diameter), thus it’s not coming in ultra light. The flakes may be getting shredded a bit up high in the wind even before they get down to us in line with what PF was saying. I updated the accumulation data with the 3:00 P.M. reading from the snowboard below, it’s definitely slowed down a bit around here:

12:00 P.M.: 0.0”

12:30 P.M.: 0.9”

1:00 P.M.: 1.6”

1:30 P.M.: 2.4”

2:00 P.M.: 3.2”

2:30 P.M.: 4.1”

3:00 P.M.: 4.5”

Looks beautiful out there but I can't imagine what's happening further south towards MRG/Fayston/waitsfield/Warren/STarksboro area...lots of 6-10" reports from friends. Lake effect upslope combo crushing that area.

Coastal I'm in Stowe. I live at 800 ft but I'm at my moonlighting job till 11 tonight at 1000 ft.

May i ask you knowledgeable weather people something? Why does NWS consistently and almost invariably totally miss these upslope events?

We've got a good 6-8" down at 1500' and counting. 18 degrees.

Sorta simple. Upslope generally only affects elevation. Say 2000ft and up. NWS forecasts for the people. people don't really live up above 2000ft. PF, Jspin, myself and others sorta maybe, just a touch care about making the schuss. So we look more at what's it is going to do above 2000ft. That and if you don't really know what you are looking for, you'll miss the signature of an upslope event.

Im at 1500' near the base of lincoln peak. We have at least a foot and im being conservative. Best guess is 14-16". My understanding is there is another 6" or so up on the mtn judging by reports of what was down at the end of the ski day.

Light medium size flakes now at 15F.

Event totals: 7.6” Snow/1.19” L.E.

I headed up to Bolton for a couple of runs this afternoon, and there was certainly inch per hour snowfall up there with some brisk winds. At a wind-sheltered spot at mid mountain (2,500’) my best estimate would be 7 inches of accumulation as of ~4:45 P.M. I hiked up for a few turns above mid mountain, and in wind sheltered spots folks are going to have a lot of fun tomorrow. I could see from Route 2 that there was backed up traffic on I-89 in the northbound lane due to the closure, but it was moving better when I was on my way back home. Down here at the house I found 5.7 inches of new snow on the snowboard, representing the snowfall during the 12:00 P.M. to 6:00 P.M. collection period. Relative to mid afternoon, the snow is definitely getting fluffier now, with somewhat larger flakes, so it’s not surprising that the overall density for the collection during the afternoon period came in at at 6.0% H2O, which was the lower range of my earlier estimate. I’d say the current snowfall is sub 6 % H2O stuff, probably in the range of 4 or 5% H2O. The radar still shows the moisture stacked up against the Greens, and we’ve picked up another 0.5 inches since the 6:00 P.M. snowboard clearing.

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

New Snow: 5.7 inches

New Liquid: 0.34 inches

Snow/Water Ratio: 16.8

Snow Density: 6.0% H2O

Temperature: 17.6 F

Sky: Snow (5-12 mm flakes)

Snow at the stake: 9.0 inches

Powder and jspin.... What town do you guys live in? Jspin what is your elevation?

Coastal, I’m at elevation 495’ in Waterbury as others mentioned, near the Waterbury/Bolton line. There’s a map of my rough location in my signature, and more detailed information about our location on our web page:

Thanks. I follow your predictions and cant thank you enough. I understand nws' target audience but i would think they would just mention the possibilities. Whatever, ive spent quite a few epic days in thigh deep powder after btv predicted 2-4". Keeps the crowds away. Oh and its snowing harder again.

The evening snow reports list from the BTV NWS (below) certainly shows the pounding that is going on down in Addison County, in line with what Powderfreak talked about earlier. We’ve had well over an inch of new liquid equivalent incorporated into the snowpack down here in the valley from this event, and with the consolidated base put together by the front and middle of this storm, we could be looking at some natural terrain openings depending on how the snowfall and winds play out tonight. Although an all-snow event would have been great, adk did talk about how nicely this storm could potentially play out, even in “cutter” form.

I love the reports guys. I'm definitely jealous. Lake Champlain effect snow FTW in Addison County especially. Only a light dusting from the upslope here in the Berkshires earlier today. Not like we get it that much compared to you guys anyway. If only I had a nice body of water like Lake Champlain just to my west...

Hmm...this gives me an idea. Perhaps we could build a massive dam to block the Hudson River near Poughkeepsie and create a large lake in the Hudson and Mohawk Valleys by flooding Albany and the surrounding environs. Now that would create some nice upslope snow here in the Berks and NW hills of CT.

Or better yet we just bulldoze VT and turn it into a giant manmade lake.

1.3" so far in Williston,VT on my final night here before unfortunately having to go back south. Got in some good runs at Bolton valley on the 26th despite limited trails.

EDIT: Radar trends show the snows starting to cut off from west to east across VT now.
