It turns out that we likely get a substantial May snowstorm here in the Northern Greens about every other year on average. It probably feels like May snowstorms are rarer than that, maybe because, well… it’s May. By this point in the season it typically hasn’t snowed in a few weeks, we’ve had some warm weather, Memorial Day is approaching, and people are well along into thinking about spring and summer. But I felt as though I’d been out on fresh snow several times in May since we’ve been back in Vermont over the past decade or so, and being curious about the actual numbers during the lead up to our current storm, I checked my ski report archives to see. Indeed, with today’s storm that makes at least five significant May snowstorms in the past decade. Here in the Northern Greens we also don’t catch the brunt of every May snowstorm that hits the Northeast, especially with the Presidentials in the mix, so I suspect that for the region as a whole the frequency of May snowstorms averages out to somewhere around a storm each season.
“…we likely get a substantial May snowstorm here in the Northern Greens about every other year on average.”
Whatever the actual frequency is for these May snowstorms, we’ve got one going on now. We’ve been monitoring the potential of this current storm for several days in the New England forum at American Weather, and the mountain snowfall was well under way last night. That meant that this morning was time to get a sense for what happened where and decide on a good location for some turns. After checking out the accumulations on the various mountain webcams this morning, I decided to head to Mt. Mansfield for a ski tour. I hadn’t seen any obvious differences in accumulations at the various resorts from the webcams, so I opted for Stowe because they seemed to have the most substantial existing snowpack right down to the base elevations.
As expected, it was a cool, borderline wintry morning as I made my way to the mountain. Temperatures were in the upper-30s F in the mountain valleys, and mid-30s F at the resort base. I’d seen on Stowe’s web cams that the North Slope area had its typical late season residual snowpack, so I chose that for my ascent route. By the time I got out on my tour, the snow level was certainly rising relative to its lowest point overnight or this morning when there were more optimal temperatures and snowfall rates. New snow accumulations varied considerably depending on the underlying surface, with the best accumulations and retention found atop the existing snowpack.
“The amount of dense snow up high meant that you had plenty of cushion for some nice powder turns.”
Continuing up from the North Slope area, I headed through the Fourrunner Quad Summit and up the Toll Road past the Mt. Mansfield Stake to the Mansfield Summit Station at around 3,850’. Precipitation was snow at all elevations on my ascent, and it was fairly light for the most part until I got to the Summit Station along the Mansfield ridgeline. While I was hanging out there refueling and changing over for the descent, the intensity of the snowfall ramped up somewhat, with lots of tiny flakes at first. Eventually though, the snowfall picked up to a pounding of much larger flakes. There was definitely a lot of liquid coming out of the sky at that point, and my Gore-Tex® was getting a workout.
Observing the new snow accumulations along my ascent, the big jump in depths really seemed to happen between 2,000’ and 3,000’. Above 3,000’ I didn’t really see too much with respect to additional accumulation, so presumably temperatures were sufficient down to 3,000’ to maximize the snow from the available moisture right from the get go yesterday.
Here’s the elevation profile for the accumulations I found this morning:
500’: 0”
1,000’: 0”
1,300’: T
1,500’: ½”
2,000’: 1”
2,300’: 3-4”
2,500’: 5”
2,700’: 6”
3,000’: 7-8”
3,500’: 8”
3,850’: 8”
The amount of dense snow up high meant that you had plenty of cushion for some nice powder turns. Of course, the density also meant that the snow was Sierra Cement/Cascade Concrete and you had your work cut out for you with respect to getting those powder turns. I had my midfat Telemark skis, and let’s just say that the Tele turns in today’s snow were a lot of work. It is mid-May though, so even dense powder turns this time of year are always a treat, and getting the workout is a big part of the experience anyway.

In some cases it wasn’t just the descent that added an extra challenge due to the dense snow. I followed a pair of skin tracks on my ascent and noticed that in some spots the new snow had stuck to their skins. I wasn’t having that issue with my skins, but I eventually caught up to the gentlemen who were making the skin tracks, and they said for them it was an issue when they traveled over areas without an existing snowpack. I was able to pay them back for their helpful skin track by setting the track for the second half of the ascent, and while I didn’t see them on the descent, I saw them back at my car and at Edelweiss Deli where I grabbed a sub for lunch (great minds think alike) and it sounds like they had a great tour.
Wintry conditions in May are typically quite ephemeral, so I guess we’ll be back to spring skiing soon, but these late season powder days are always a treat. There’s a certain mystique with these late season elevation snow event because it feels like you were in another world when you get back to the strong sun, spring warmth, and rapidly emerging greenery in the valleys.
