NNE Winter 2012-13 Thread III

Recommended Posts

If wind is very high Bretton Woods is the least likely to be affected.  You could drive there during the day if Attitash happens to go on hold.

 

I'll say from experience though that in very deep new snow, there isn't much terrain at BW steep enough to get you through it. Little is more frustrating than constantly getting stuck in deep-and-not-steep. That said, maybe not so much of a problem if ratios are high, and/or if totals there aren't much more than a foot. 

 

Only other meager advice I can offer is if wind swings out of NW as the coastal departs, Cannon's aspect seems to make it immune.  I skied there the day after Valentines Day 2007 in 26" of wind affected snow (5-6' natural whales up top) and it was wide open with only the very occasional gust when everything else in the Whites except BW was on wind hold.

I was thinking the same thing about pitch, but Bretton Woods has that new T-Bar that supposedly reaches some better terrain.  Also it's about 1/2 the distance as it is to Cannon from Attitash.

We've got a Winter Storm Watch.  Not sure it verifies but whatever.

I think at least 6-12" verifies with latest Euro guidance. 1.1" qpf at St Johnsbury...with 15-20:1 ratios is a solid 15-20"

From BTV...as expected.

 

 

EXPECT A PROLONGED PERIOD OF SNOW ACROSS THE REGION FROM LATETHURSDAY NIGHT THROUGH FRIDAY NIGHT. THE BULK OF THE HEAVIER SNOWWILL FALL ACROSS NORTHERN NY LATE THURSDAY NIGHT THROUGHFRIDAY...AND IN VERMONT FRIDAY THROUGH FRIDAY NIGHT. BLEND OFMODEL QPF SUGGESTS AMOUNTS OF 0.75 TO 1 INCH WILL BE COMMON. WITHRATIOS OF AT LEAST 15:1 EXPECTED...THIS SUPPORTS WIDESPREAD SNOWAMOUNTS OF 8-14 INCHES. LOWEST AMOUNTS MAY WIND UP BEING INNORTHEAST VERMONT DUE SHADOWING.

For for the influx of posts, but here is my latest thinking for all of northern VT, NH, and SW ME:

 

In Vermont-

BTV: 8-12"

Stowe: 12-16"

Rutland: 12-16"

Montpelier: 10-14"

St. Johnsbury: 8-12"

 

In New Hampshire-

Littleton: 6-10"

Berlin: 8-12"

Lebanon:12-16"

Plymouth: 14-18"

 

In Maine-

Fryeburg: 14-18"

Lewiston: 18-24"

Portland: 24-30"

Jackman: 6-10"

 

I will update these throughout the next few days. I can really see these totals going either way (up or down) so stay tuned!

I love the 15Z SREF plumes for St. J.

Mean is 19.6 with a Max of 51.96.  Once you take out the 3 highest the mean is still int he 14/ 15 inch range.

Thanks for sticking your neck out with those details.

 

MBY is about 1/3 the distance from LEW to Jackman, so I'll interpolate accordingly (and hope for one of those killer bands noted in GYX's AFD.)  +SN at 10F with strong winds would make for an interesting Friday evening.

Oh and 4" fell today at 1500ft with 6" at 3000ft+.

There's an inch or less in town and then you drive up to advisory level snow in the parking lot of the ski area haha.

 

Hey pf

 

Im heading up to Stowe for the weekend from penn state with our ski club.  I imagine conditions have dramatically improved over the last week with todays snow and the surprise 4-7 a couple days ago.  Hopefully we make it up fine on friday lol.  I'm absolutely pumped to ski on what looks like 14 or so inches of powder on saturday!

Not thrilled with the 18z gfs. Seems to weaken the northern system quite a bit.

Ummmm...its the 18z GFS.

 

I'm going with a widespread 8-14 in the ADK and Nor. VT.  A few higher elevations prob. 12-16 range is reasonable. Fluff compacts so ratios of 15 or so to 1 don't mean a ton for me when it all verifies out. It helps, yes. But like PF I don't bank on it.

 

The interesting zone is going to be the Nor. ADK where some places - Lyon Mtn maybe- could pop into the 20 range.

Well, I keep seeing people in the other threads getting pounded for keeping alive the idea that the off runs are the garbage they once were. Anyway...it was just one comment on one run...

Nice! Yeah conditions are much better than they were at the start of the week. This recent snow is our upslope cold smoke fluff, so it doesn't pack down as well as synoptic snow would, but that should change on Saturday. The groomed runs are getting real nice with the new snow but its dust on crust (albeit deeper than dusting) on ungroomed trails.

It's certainly a concern but I think most models have that northern stream wave a little juicier. We aren't getting touched by the coastal but that northern stream seems robust. But that's why I'm hesitant to go big up here. If everything goes to the coast too early we could be in a screw zone...while some models keep a better moisture connection across NNY and NVT.

We are getting touched by the coastal though. Without the dynamics and extreme lift associated with the phase there's nothing to wring the moisture out and expand the coastals precip shield.

Saw that on the GFS too--I'm sure we'll do just fine unless the coastal heads futher east than current thinking.

 

Crazy to watch these model runs though for SNE.  It's going to be a pretty wild day one way or another.

 

One thing I would say for sure is that tomorrow's gon' be a banner day for grocery stores and gas stations from Maine to NJ.

Yeah I guess I phrased that wrong...maybe the CCB and comma head is what I meant. I mean on all RH and lift plots, once that coastal really gets going we are sort of done with the real accumulating snows.

Event totals: 0.4” Snow/0.01” L.E.

 

There was 0.4” of snow on the board when I got home today – it had definitely settled and/or some sublimed, but either way it was still quite dry at 2.5% H2O.

 

Details from the 5:00 P.M. Waterbury observations:

 

New Snow: 0.4 inches

New Liquid: 0.01 inches

Snow/Water Ratio: 40.0

Snow Density: 2.5% H2O

Temperature: 19.9 F

Sky: Clear

Snow at the stake: 3.0 inches
