The first flakes of the season at our site in Waterbury were back on the 16th of the month with that last big snow event, but thanks to the system moving through yesterday into today, we accrued the first accumulations I’ve seen here. Temperatures were certainly above freezing here in the valley, but the intensity of the precipitation is what brought on the accumulation when one of the more active cells on the radar came through our area.

Accumulations finally started to take hold down at our elevation of 500 feet in the Winooski Valley in Waterbury when one of the more potent cells of precipitation crossed the spine of the Green Mountains in our area.

Based on posts that were showing up in the Northern New England thread at the American Weather Forum yesterday, it was clear that many valley locations were starting to see accumulations as the temperatures came down. Temperatures dropped well into the 20s F overnight, so by morning, CoCoRaHS reports revealed valley accumulations of anything from a trace to as much as a few inches in a stripe across Northern Vermont.

With this latest round of autumn snow culminating in over a foot of accumulation on Mt. Mansfield, the setup was calling for some early season turns. With the way the temperatures were expected to rise today, I think yesterday was the way to go for potentially the best overall snow quality for powder turns, but I was too busy to get out to the slopes. I did get out this morning though, and while snow preservation was undoubtedly better yesterday, the clouds totally disappeared today to reveal incredible snowliage in the sunshine.

I started my ascent from the Gondola base at 1,600’ and walked with my skis on my pack for a few minutes to get above the areas with the most melting, then I transitioned for touring and skinned up from there. The snow was already becoming spring-like down low in the sun, and areas in the shade featured refrozen snow. So even yesterday, the freezing level made it above the base elevations. I encountered my first real winter snow that had not seen a thaw-freeze cycle at about 2,800’ in the shade, and then at around 3,200’ I began finding some winter snow even in the sun. I made snow depth checks along the way, and here’s the depth profile I found in the late-morning to midday period:

1,600’: T-2”
2,000’: 4-5”
2,500’: 9-10”
3,000’: 12-13”
3,600’: 13-14”

Depths had consolidated a bit even up at 3,600’ based on Powderfreak’s pictures from yesterday, and the sun was really doing a number on the snow down low. The Gondola terrain gets hit by the sun, and the accumulations down near the Gondola base were just about gone by the time I finished my descent.

In terms of the skiing, I encountered just about every sort of condition that Mother Nature can throw at you, from dense, silky powder, to refrozen areas with unbreakable melt crust, to spring snow, to sticky, freshly melted snow. Once you were down below the driest snow up top, the best approach was to fucus on the snow that was in that happy medium between seeing the most sun on the skier’s left, and that which had seen no sun on the far skiers right in the shade of the trees. The snow on the skier’s left that had seen some hours of sun was getting sticky, and snow that was shaded by the trees was still frozen with either an unbreakable or breakable melt crust, but in between there was an area of quality snow that had seen just enough sun to soften up but not get sticky. Once you were down below roughly 2,000’, everything was melting, so you just sort of kept going until you felt the snow was too thin. You could still make it all the way to the base with the help of shaded areas depending on what level of rock skis you might be on, but I took off my skis for the last few hundred vertical because I didn’t want to beat them up too much.

That was a solid dump for the middle of October though, and with the bonus snowliage it was a great way to kick off the season.

Third round of early season snows for Vermont’s Green Mountains have been the most impactful yet

The Sugarbush Golf Course Webcam was starting to reveal the mountain snows on Tuesday as our latest round of winter weather hit the Greens.

We’re wrapping up our third round of early season snows here in the Green Mountains of Vermont, and this cycle has certainly raised the bar with respect to accumulations. For several days, the weather modeling has shown the potential for a solid shot of snow at elevation, and as of Sunday’s runs, it was becoming more obvious that the event was coming together.

Personal observations related to this latest cycle of snow began for me on Sunday – I was up at Bolton Valley around 2,500’ and was getting into some frozen precipitation even down at that elevation. Right around that time, Powderfreak reported in from the upper elevations of Stowe Mountain Resort at the Gondola with a picture of big flakes coming down. As of later that afternoon, the snow level was around 3,200’, but it was expected to potentially mix all the way down to the valley floors by Monday. Late that evening, the 3,000’ Lookout plot on Mt. Mansfield was showing about a half inch of snow, so accumulations were clearly beginning.

By midday Monday, the Mt. Mansfield Lookout plot was at 2 inches of accumulation, and later that evening, snow was mixing in down to the valley floors as expected.

As of Tuesday, snow accumulations were pushing farther down the mountainsides, and the evening update from Powderfreak was that the 3,000’ Lookout plot had seen 7 inches of snow up to that point in the event. Snow was even mixing in with the rain down at our house at the 500’ elevation in the Winooski Valley, and our site recorded its first trace of snow on the season.

By Tuesday, accumulations were starting to appear in the upper elevations of Mt. Mansfield, with snow levels continuing to drop and accumulations jumping as the event continued on into Wednesday.

Wednesday was the culmination of the event, with accumulations on Mt. Mansfield topping out around 15 inches. At Stowe Mountain Resort, the snowmobiles and snowcats were out trying to open the Gondola for summer/fall operations for the tourists. The snow depth at the famed Mt. Mansfield Stake came in at 12 inches, which is certainly solid for mid-October depths.  Powderfreak put together a great collection of photos from the upper elevations of Mt. Mansfield that nicely showed the accumulated results from this early season snowstorm.

This was a great early season event for the local mountains, and even at elevation, there were still enough leaves left on some of the trees to create excellent snowliage images.

Another round of Vermont snows: accumulations have begun

We had our first reported snow of the season here in Vermont over a month ago when flakes were spotted atop Jay Peak, but this latest round of winter weather has now brought us the first actual accumulations of the season. Our initial images of the accumulations came out yesterday morning when Powderfreak sent out some shots from the higher elevations of Mt. Mansfield during his usual Stowe Mountain Resort duties. Later in the day he sent along a nice image of the cloud ceiling and flakes falling on Spruce Peak while he was out on an afternoon hike. The snow was down to at least the 3,100’ elevation as of the afternoon, and with more moisture pushing into the spine of the Greens according to the radar, the potential for some additional overnight accumulations was looking good. The moisture seemed to be drifting a bit south though, and I saw a comment from Powderfreak that he felt the Central and Southern Greens would have the better chances for accumulations during the overnight period.

His thoughts were right on track, and by morning we were alerted with pictures from the Killington North Ridge Webcam of some more substantial accumulations. Up here in the Northern Greens, where the mid-level lifting mechanisms for precipitation weren’t as strong, the higher elevations of Mt. Mansfield picked up some ice accumulations and another coating of snow.

A shot from Killington’s North Ridge Webcam of today’s new snow during our period of first snow accumulations for the 2024-2025 winter season. Accumulations began in the area yesterday and the Central Green Mountain s picked up some of the best snows overnight.

Looking at the data for the average date of first accumulations on Mt. Mansfield, October 9th is right on track for first accumulating snow on Mt. Mansfield – the mean date is October 11th ± 14 days, and the median date is October 10th. Last year was a bit on the later side on October 22nd, but the year before was very similar to this one with snow coming on October 8th.

So, the 2024-2025 snowfall season has begun here in Vermont, and we may see more snow in the coming days. The snowfall maps from the weather models are starting to suggest accumulations next week, and the National Weather Service office in Burlington mentions that there is possibility for accumulations above 2,000’ in their most recent area forecast discussion.
