First storm of the winter season in the Greens

An image from the Burlington National Weather Service showing projected snow accumulations for our first October snowstorm of the season
The projected accumulations of roughly a foot of snow in the higher elevations of the Green Mountains came to fruition today.

We’ve had several days to watch the forecasts building up to a potential first snowfall of the 2016-2017 winter season for the Green Mountains of Vermont.  The storm was projected to move along the coast and up into the Canadian Maritimes, which, as usual, would put it at the point where cold, moist air could wrap around and hit the spine of the Greens from the northwest.  Yesterday afternoon the snow levels began to drop toward the summits, and as daylight began to fade we were able to see that snow was starting to accumulate up near 4,000’ via the new Lincoln Peak Snow Cam.  At around 10:30 P.M. I looked outside and saw that snow had made it all the way down to our house at just 500’ in the Winooski Valley, which meant that the mountains were well into the snow.  We’d accumulated a couple of tenths of an inch of snow at the house before I headed off to bed.

As of this morning we’d picked up about a half inch of snow down at the house, and accumulations reports began to come in from around the area.  One of the more surprising results the storm was just how much snow had accumulated at relatively low elevations on the western slopes of the GreensThere were reports of up to 6 inches of dense snow in areas that still had substantial leaves on their trees, and combined with some aggressive winds that meant downed trees, travel difficulties, and some power outages.

In the higher elevations, Powderfreak reported finding 5.5 inches at 1,500’ the base of Stowe Mountain Resort, a foot at 2,000’ – 2,500’, and accumulations seemed to generally top out in that range up and down the Central and Northern Green MountainsBolton Valley reporting 9 inches, 11 inches were found at the Mount Mansfield Stake, and there were images of waist-deep drifts at Jay Peak.  I didn’t get a chance to get out on the slopes because we were down at a New England Revolution match at Gillette Stadium, but it looked like the dense snow did a decent job of covering up surfaces to enable some fun October turns.  The weather looks relatively cool this week, so the snow shouldn’t be going anywhere immediately, and I heard Killington even plans to open on Tuesday to start the lift-served ski season.

Bolton Valley and Backcountry, VT 16FEB2013

Although the recent midweek storm gave a decent shot of snow to the Northern Greens, with Stowe picking up a foot of snow, and Jay Peak picking up a foot and a half, it’s still been fairly dry in general.  Because of the rather high Froude Numbers for that storm, the more west-side locations of Smuggler’s Notch and Bolton Valley saw them picking up just a half foot of snow during that event, and that’s what Bolton was reporting for their seven-day total as of today.  The dearth of snow and a holiday weekend had me thinking a tour on the Nordic/backcountry network was in order, because there’s some excellent snow out there, but there’s been enough time since if fell for lift-served traffic to pack it down pretty well by this point.

“Depths of powder above whatever
firmer subsurface lay below were in
the 8-12” range, with a bit of that melt
layer in there in the lower elevations
or on south facing terrain.”

I devised a somewhat ambitious tour for today, at least with respect to what the boys might be willing to accommodate.  It would be an opportunity to show E and the boys the two glades that I discovered last month on the 19th and the 27th.  The plan was to skin up Bryant to the Bryant Cabin, descend through the first glade, then connect over to the alpine trail network, catch an assist from the Wilderness Lift to the Wilderness Summit, traverse out on Heavenly Highway, ski the second glade, and return to the car via the Nordic/backcountry network.  If we couldn’t complete the whole tour we’d have some opportunities to truncate it as needed.  The forecast called for some sun and temperatures in the 20s F today, so it looked like we wouldn’t have to worry about anyone getting cold too quickly.

We arrived up in the Bolton Valley Village in the late morning period, and the main parking lots were getting pretty full, but we were able to get a trailside spot right on World Cup in the lower tennis court lot.  There were plenty of people about as we began our ascent, including a number participating in the “Bolton to the Barns” event.  We ran into Alex, one of my former students on his descent with the event group, and learned that he is now at Tufts Medical School, although he seemed very happy to be back in Vermont visiting Bolton Valley. Dylan asked for just one break on the ascent, and we pulled over into the sunshine along the top section of World Cup and had a snack.

Near the start of our tour when we’d passed by the Courtside 1 Condos on Broadway, we ran into a Nordic skier who was pausing there.  She inquired about the substantial width of E’s fat skis, and E indicated that they were for powder skiing.  The woman seemed puzzled because as far as she could tell there was no powder around.  She wished us luck on finding powder, but you could tell she figured it was a lost cause.  It was very interesting to hear her speak that way when just a few feet away from her off the side of the trail, you could see the powder sitting there.  People certainly have some unique perspectives on snow conditions.  As a Nordic skier, perhaps she’s got a totally different idea of what powder snow actually is, or she may have just been oblivious to what conditions were like off the groomed runs of the Nordic trails.  Anyway, in terms of the actual snow conditions, out near the car a bit above the 2,000’ mark there were 2 to 3 inches of fluffy snow above a bit of a melt/sun crust, but I suspected that crust would disappear as we got out of exposed areas and headed up in elevation.  Indeed, pretty quickly in shaded areas I found that the powder was deeper and the melt crust underneath was disappearing, and after a few hundred feet of ascent it was essentially gone.  Depths of powder above whatever firmer subsurface lay below were in the 8-12” range, with a bit of that melt layer in there in the lower elevations or on south facing terrain.

Our first descent was in the North Slope and Gardiner’s Lane areas, and the powder was very good in the upper elevations.  On our first pitch dropping from North Slope, conditions were just right so that both Ty and Dylan made some nice Telemark turns.  Later, Ty dropped a nice Telemark-style jump turn launching off one of the steeper pitches, and he was very proud of that.  The boys threw in a good amount of alpine turns, especially when they wanted to go faster, but it was all around great practice for them.  Like I’d noticed on our ascent, the last couple hundred vertical of the descent featured some of that melt crust below the powder.  We were on a south-facing slope, so that certainly wasn’t surprising.  I found my fat AMPerages to be really helpful in that terrain, and E had some nice turns on her Elements, but she’s still finding them hard to get up on edge in packed snow due to their width.  We’re wondering if the play in her boots is just too much and it’s ruining the ability to convey the necessary pressure into the ski.

We connected over to the Wilderness Double Chair and took it to the Wilderness Summit as planned, but Ty was pretty insistent on a quick descent without additional skinning.  So instead of heading across on Heavenly Highway to drop through the second glade I’d chosen for the day, we opted to descend on Peggy Dow’s to quickly get to Snow Hole.  There was decent powder in Snow Hole, although it was certainly more tracked and packed than what we’d seen in the backcountry glades.  I got off to the sides of the main route a good deal though and got a number of fresh lines, and at times the boys would follow me.  We did make a good connection back onto the Nordic network and caught a few final turns on the Telemark Practice Slope and other lower mountain glade areas before heading back to the car.  We’ll be planning another tour at some point to catch that second glade; I still want to show it to E and the boys.

Our next shot at snow appears to be coming into the area in the Tuesday timeframe.  It looks like it’s going to be a pretty standard frontal passage at face value without much fanfare in terms of snowfall, but there is definitely the potential for some upslope snow.  The crew at the National Weather Service Office in Burlington has had their eyes on the potential, and Powderfreak has been watching as well.  We’re hoping for that snowfall boost from the upslope snow, because there isn’t much forecast in terms of synoptic snowstorms in the immediate future.

Widespread frost and freeze potential in Vermont

Freeze Warnings and Frost Advisories are up throughout much of the state of Vermont tonight.

Parts of the Northeast have had bouts of sub-freezing temperatures since the end of August, but tonight looks like the first widespread occurrence of the season throughout Vermont.  We’ve got a frost advisory here in Washington County, but it sounds like some of the colder areas of the state up in the Northeast Kingdom could get down into the middle 20s F, and freeze warnings are in place.  It’s certainly time to cover up those gardens in the usual cold spots.

Frost and Freeze alerts posted for Vermont

The frost and freeze warnings map from the National Weather Service Office in Burlington Vermont for September 16th, 2011
Freeze Warnings and Frost Advisories have been posted for the entire state of Vermont.

The National Weather Service office in Burlington has posted a freeze warning for our area, and indeed the entire state of Vermont is under either freeze warnings or frost advisories, so cover up vegetation as necessary.  Though the first frost for valley locations in the Central and Northern Green Mountains does typically happen in September, the average date for the occurrence is toward the end of the month (September 27th for Morrisville and September 30th for Montpelier) so this is a bit on the earlier side.  Yesterday in the Northern New England thread at Americanwx.com, Powderfreak posted the chart from the National Weather Service that shows the average dates and ranges for first frost at some of our Vermont climate locations – mid September is in the 10th – 25th percentile.  Take a look at that post for more information about average dates of 32 F temperatures around the state.
