Ty to appear in Bolton Valley ad in Kids Vermont
An image of Ty in the powder that we took back on our December 20th, 2008 ski outing at Bolton Valley will be appearing in an advertisement for the resort in an upcoming issue of the Kids Vermont newspaper. I’ve attached a copy of the ad below; congratulations Ty!
Ty also appears in one of the interior shots in this year’s brochure from Bolton Valley, promoting powder skiing & kids, so when Powderfreak commented over in the Ski Thread in the New England Regional Forum at American Weather, I added a response and posted a scanned copy of that material. That image is below:
June upslope rain, with some snow for the mountains
After drying out to amazing low humidity on Wednesday, temperatures got really cool on Thursday and we got into a classic Northern Vermont upslope flow. There was actually some snow falling in the highest elevations of the Greens, and certainly over in the Whites. There were just a few spits of rain in Burlington when I left yesterday afternoon, but of course I got to the house and it was a steady light rain with a tenth or two of an inch already in the gauge. This morning the gauge contained 0.27” of liquid in it and I thought, heck, that’s a half foot of upslope snow right there when the temperatures are appropriate. I was looking at the radar image posted by Powderfreak at Americanwx.com and could see how at one point it exploded with 35 db and even a few 40 db echoes over our area at the junction of I-89 and the Chittenden/Washington county line, and then dissipated on the east side of the mountains once it dropped its payload:
When I submitted my report to CoCoRaHS this morning, I took a quick look at what some of the other stations had reported. I sorted the list below from around 7:00 A.M. by total precipitation, but even without that, it was pretty easy to see the locations that got the liquid:
I haven’t been able to check out the local peaks to see if they have any white on them because they’ve been socked in, but Mt. Washington got some new snow and they must have been whitened. It’s 26 F up there now with freezing fog and 50+ MPH winds. With such a good-looking forecast for tomorrow, we may head over for some turns, but these past couple of days certainly should have been good for snow preservation.
Thunderstorms and some heavy rains overnight
It didn’t seem like it rained a lot last night, but I found 1.63” in the gauge this morning, so it obviously added up. We had some losses of power similar to what Powderfreak noted – a couple short ones in the evening, and then it went back out again around 8:00 P.M. and it was gone for the night. It came back on early this morning at some point. I didn’t stay awake for it, but apparently we had thunder and lightning pretty continuously through about 2:00 A.M. This morning I was surprised to see the Winooski way back up to a level even with our local V.A.S.T. bridge and hogging almost the entire valley in our area, just like back in mid April when the snowpack was starting to melt. I think it may have even been a bit higher this time, as the typically flooded residences and farmland west of the Cider House seemed quite inundated with water. The water was probably the closest I’ve seen it to washing over Route 2 in that area – I think another foot of depth and there would have been water on the road. I was surprised it got so high relative to the amount of water I recorded in the gauge, but then I checked the CoCoRaHS maps and saw that one observer over in Caledonia County reported 3.66” of water with this event. I don’t think they are actually in our drainage, but clearly someone out to our east got a load of water from these storms overnight. Our bus was late this morning due to road closures in the Montpelier area, so things have certainly been disrupted by the water. I added an image of the VT CoCoRaHS table of Daily Precipitations Reports as of ~7:30 A.M. this morning, and it indicates that someone over in Danville got over 4 inches of liquid from these storms, so there are reports of some large amounts of liquid coming in from Caledonia County.

I headed up to Mt. Mansfield this morning to get in a workout and take advantage of the fresh snow that had fallen since Wednesday. Once I got out of the fog that had settled around our house in the Winooski Valley, there were fantastic views of the fresh snow on the Green Mountains, and Mt. Mansfield’s alpine terrain was especially scenic. I started my skin up the gondola side of Mansfield at around 7:00 A.M., and found the following new snow accumulations with respect to elevation:
1,600′: ~1/4″
2,000′: 1-2″
2,500′: ~4″
3,000′: ~6″
3,600′: ~10″
It was a little tough to get the depths on what had fallen because the new snow was so well integrated onto the old base, but those were my best estimates and I’d say they’re pretty decent. In terms of the skiing, the new snow was certainly more akin to dense Sierra Cement than Northern Vermont’s famous Champlain Powder™ fluff, but the turns were really nice; the dense snow did a great job of keeping one up off the old base.

Snow line around 1,500′ this morning
It was ~41 F at the house this morning, so I suspected that the snow level was still a bit high for new powder in the easily accessible elevations, but I checked in at Bolton on the way in to Burlington this morning to get a handle on where things were at in terms of base and new snow. I could tell that it wasn’t yet a huge hit below 2,500’ yet because the cars coming down the road didn’t have snow on them, but the precipitation certainly looked like snow up high. Here’s the vertical temperature profile I observed on the Bolton Valley access road around 7:00 A.M. with comments on the precipitation/accumulation; hopefully it will be useful for other mountain recreationalists:
340’: 41F (light rain)
950’: 40F (light/moderate rain)
1,100’: 39F (moderate rain)
1,500’: 38F (moderate rain/snow)
1,800’: 37F (moderate snow)
2,000’: 36F (moderate snow)
2,100’: 35F (moderate snow, accumulating)
As you can see from the above list, snow wasn’t accumulating until I reached the village at 2,100’, but it seemed to be accumulating on most surfaces other than the pavement, and there was probably ¼ inch down when I was there. Skier’s left of Beech Seal showed a couple of breaks in coverage, as I suspected it would based on my Sunday observations, but it was still pretty close to continuous.
Even back down in the valley, there were some bouts of moderate precipitation, so hopefully that continues to hit the mountains. Roger Hill was thinking that the snow level would rise a bit during the day today, so that may have to be factored in as well.

It was a busy weekend culminating with Ty’s first communion and the ensuing party today, but once things had wound down by the afternoon, I had a chance to head up to the mountain and make some turns. There was fresh snow on April 23rd, but the snowpack has certainly crept upward in elevation since April 17th, which was the last sunny day I was out on the mountain. At that point the first signs of natural snow appeared at around 900’, but today the natural snow didn’t appear until roughly 1,750’. Timberline had just a couple patches of snow remaining, but up at the main base the snowpack was quite substantial. There is continuous snow coverage on Sherman’s Pass to Beech Seal, and possibly other routes as well, and I caught a sunset run through the corn to finish off the amazing sunny weekend that we were given. For more details and pictures, click through to my Bolton Valley trip report from May 1st, 2011.
Heavy rainfall and more high water today
I haven’t seen any snow with this system, but last night’s precipitation seems worthy of note because we had 2.30 inches of liquid and the Winooski is back up even with our local VAST bridge as it was on the 11th, despite the fact that most of the snow has already melted in the lower elevations. Some area schools are closed due to road access issues with this event. I just summed my CoCoRaHS numbers for April and with this latest event the total liquid is right at 8.00 inches for the month thus far. While I had that open I grabbed a few additional liquid numbers. For the 2011 calendar year up to this point at my reporting location the liquid precipitation is at 20.46 inches, for the 2010 calendar year the total was 54.17 inches, and for the ’10-’11 snowfall season as it currently stands (October 15th, 2010 – April 16th, 2011), the total was 28.09 inches.
The snow in the yard has melted
The last of the snow in the yard melted today, so I can finish off that portion of my seasonal snowfall numbers. The data for the last of the snow melting out in the yard (as of this season the mean date is April 15th ± 10 days) is actually something I’ve recorded all the way back since our first winter here (2006-2007) and April 24th is one day later than the previous record I had down (April 23rd, 2007). This puts the continuous snowpack season in the yard at 141 days, which is exactly the same number recorded for ’06-’07. Both of those seasons had slow starts with poor November snowfall, and snowpack that did not become established until early December, so they are well behind the highest value of 152 days recorded for the 2007-2008 season. The next benchmark I’ll monitor will be when the last of the snow melts out in our neighborhood, which tends to be about a week beyond when the snow melts out at the house.
As I was skiing at Bolton yesterday I was reminded of some outings in April ’07, and realized that while the snowpack is in excellent shape this spring, the skiing this month has really paled in comparison to the equivalent period back in ’07. Even down at this elevation we had almost two feet of snowfall in April ’07, and this season we’ve had just 4.4 inches. I’m not sure what the mountains have had this April, but in ’07 it was measured in feet; I skied one day mid month on the mountain where I found up to 19 inches of new snow, and that was for just one of the storms. The reading from the Mansfield stake on Friday was certainly respectable at 82 inches, but for the same date in ’07 it was actually at 84 inches. It’s really been just an issue of the storm track this April; the moisture has been there, but the track has been too far to the north/west to get into the appropriate combination of precipitation and temperature. With a good track over the past few weeks we probably would have had another April 2007 on our hands. I think that the past couple of springs have been so poor in the snowfall department that some perspective has been lost on April’s potential, this one is good in terms of base/snowpack, but I’d say subpar for snowfall (we’re still below average by a few inches at the house).
Bolton Valley, VT 23APR2011
While the weather was full-blown spring with sunshine and corn snow yesterday at Sugarbush, today it was back to winter with a bit of fresh powder in the mountains. I headed up to Bolton for some turns and found snow that was dense enough to keep me from touching down to the old subsurface much of the time. The base snow provided wall to wall coverage, so with the powder on top it was a great ride. For all the details and pictures, go to my April 23rd trip report from Bolton Valley.
