NNE Winter Thread II

Recommended Posts

BTV has been killing it with the discussions lately. Taber with some detail on this one. From what I've seen, I agree completely and actually think I'll half of what the west side gets. This has the look of a true eastern Champlain Valley/West Slope event.

That is a great discussion. YOu can see that mid level capping inversion too if you look at the time/height. Certainly feels like a western slopes favoring event. Though anytime there is a NW wind it's hard to judgewhat happens in the upper above treeline terrain. Once you get that snow to move it's going to be deposited somewhere. ...and that is likely the upper eastern slopes of mansfield.

Unreal PF haha. Enjoy. Thinking west slope enhancement....maybe 6-10".

Should be a solid 2-4" for the NEK.

Yeah I agree with you... these events with arctic air moving in tend to be west side and even Champlain Valley events. Winds look to be more northerly, too, which aids those areas, but not here. The east side needs a more westerly component to get enough momentum to push the snow over the Spine. NNW often just doesn't have the juice to really spill over.

I like about 3-4" here at my place, though the ski resort could double that on the Spine.

Enjoy! One zone north, no accum mentioned and merely "chance" (though high chance - 50%) of snow. Trend is our friend, though.

with that in the books, you're now on track to for average december at your spot, then?

Absolutely, we could even end up above average. Thanks to this last storm, the snowfall total for the month is 40.7” (from 5.95” of liquid). Since the mean December snowfall here is 41.6”, we should easily be getting there if the forecast is correct (2-5” through tomorrow night). The point and click actually looks reasonably snowy right through the New Year:

Everything is so much nicer with a thick coating of snow across the landscape.

And there's nothing more classic than cars sporting a thick mushroom cap of snow. Of course this one is from NJ ;) Out of state plates outnumber our green VT plates like 4:1 this week. Its tourist week from Xmas to New Year's... every lodging is sold out and this has easily been the busiest Xmas week so far in the 5 years I've worked at the ski resort. Well timed 5 feet of snow in 12 days at the ski resort will do that. And that's not even that much considering Sugarbush is now up to 80 inches in the past 2 weeks. That's nuts!

Hey cpick, VTC used to have a hill with a rope tow, you ought to see if you can get them to fire that up for you to take a few turns!

lol guess what!? We drove over to that hill at 11am and 5 of us had tubes and hiked up the hill. We took about 5 runs on the tubes (after we establised a path). Was a great time. My friends dad who is the prez says they will likely turn the toerope on for weekends for skiers/snowboarders.

I think the mrv is seeing an increase in tourists too this week. There were cars parked in a lot i had never seen used before and the vehicular traffic into waitsfield was heavy.

This morning was a little weird with the freezing mist to start off the day. Didnt seem to effect the snow though. Excellent riding. Plenty of snow in them there hills.

After tomorrow night, Cold and dry with a few clippa shots over the next 10 days or so

I can deal with that considering that I'm down both my plow truck and my snowblower. The old tractor (with a plow) is the last arrow in my quiver until I get the others fixed--driveway's 1800' long, narrow and a bit steep. Not a small task. :axe:

Just up the road in Northfield, Norwich University used to have a full blown chair lift right on campus. Every once in a while you hear a rumor about them reopening it but they would need to do quite a bit of work to get the trails back. Glad you had a good time in my old stomping grounds. I used ride by VTC everyday on my way to high school. That ridge gets some hellacious winds in winter. There were many days the school bus would be drift busting on the way to school.

That sucks. I was bumming thinking I was going to have to shovel my 30' driveway! Well I guess as snow junkies there could be worse problems.
