I was just listening to Roger Hillís broadcast, and he said to watch out for snow tomorrow night; heís expecting some accumulation in the higher elevations, with flakes reaching the valleys as well.

2-maybe 6" for Jay local up-slope on track Friday AM


It was nice to hear about this in your WDEV broadcast this morning Roger, thanks for keeping us updated here at American Weather; the skis are ready if things work out.

Mountain snow is on the way...the Lamoille County Zone Forecast looks nice:


I just looked at the point forecast for the higher elevations of Mt. Mansfield, and it also looks appealing:


Tonight: Snow showers. Low around 29. Breezy, with a south wind 17 to 22 mph becoming west. Chance of precipitation is 90%. Total nighttime snow accumulation of 2 to 4 inches possible.

Friday: Snow showers likely, mainly before 5pm. Cloudy, with a high near 30. Windy, with a northwest wind between 29 and 32 mph. Chance of precipitation is 70%. New snow accumulation of 3 to 5 inches possible.

I canít see an obvious snow line from here at the house, but itís down to at least the 2,000í because accumulation and falling snow is visible on the Bolton Valley Live Web Cam:



The temperature reported by the weather station at the resort base is 31.4 F, so itís below freezing there.† It will be interesting to see whatís gone on atop Mt. Mansfield so far, as the temperature hit 32 F there around 3:00 A.M., and thereís already been a decent shot of precipitation.† As of this morningís 6:00 A.M. CoCoRaHS report thereís 0.43Ē of liquid in the gauge here at the house, and the weather station at the base of Stowe (1,640í) reports 0.34Ē of liquid and a temperature of 34.7 F.



I can pass along a few observations from my transit out of the land of upslope into the Champlain Valley this morning.† It was pouring rain at the house (495í) in Waterbury when I left, and temperatures were in the upper 30s F through the Winooski Valley, but there were crystals in the drops of rain hitting the carís windshield.† The heavy rainfall continued until the center of Jonesville (320í), and then it began to taper off.† The intensity of the precipitation was just showery in Richmond (300í), but cold air was definitely working in, because it was actually snowing at times.† That intermittent rain or snow continued up toward the high point of I-89 there in Williston (620í), and then that gradually tapered away as I approached Burlington.† In Burlington itís actually partly cloudy with a pleasant strip of blue off to the west across the lake, but even here (380í) there have been a few spits of frozen precipitation.† Not surprisingly, the view from here at UVM is one of a wall of precipitation hiding the Green Mountains off to the east.



Event totals: 0.2Ē Snow/0.68Ē L.E.


It was in the upper 30s F when I left Burlington this afternoon, and while weíd seen some spits of frozen precipitation there earlier today, nothing was falling when I left.† Temperatures remained in that upper 30s F range through the Winooski Valley and into Waterbury Center; and it snowed continuously in the mountain valleys, although it wasnít accumulating.† Finally, as I headed through the Moscow area near Stowe, I saw that the temperature had dropped into the mid 30s F, but there was still no visible snow accumulation.† It was right around 1,000í near the Matterhorn that I first started seeing accumulations of snow, and by the time Iíd reached the base of Mt. Mansfield at around 1,500í, the temperature was near freezing and the snow was accumulating easily.† I found an inch or two of new snow outside the Mansfield Base Lodge, and even down at that elevation it was quite dry.† I skinned up to near 3,500í just a bit below the top of the Fourrunner Quad, and it was a little tough to get an accurate measurement of the snow depth due to drifting, but Iíll go with 5 inches as my best guess.† I did find areas where accumulations were as deep as 7 inches, but those seemed to be spots where snow had collected efficiently with help from the wind.† As of 5:20 P.M., the depth of snow at the Mt. Mansfield Stake had gone up by 4 inches, so that certainly seems to be in the range of what I found up in the higher elevations.† Anyway, the snow was nice medium-weight powder, and although this storm hasnít delivered as much as that last one a couple weeks ago, the powder is of much higher quality.† Itís not totally bottomless powder skiing everywhere, but in many areas it is, and with the nice base snow below, it makes for some smooth and effortless turns.† I added a couple of shots from today below:




It snowed the whole time I was on the mountain, and it was definitely accumulating, but the snowfall was generally light in intensity.† Temperatures were dropping when I left the resort around 6:30 P.M. or so, and I saw accumulating snow all the way down to The Gables Inn on the Mountain Road, which is around 750í.† I had dinner with the family at Fridaís, and when we were done, snow was accumulating right in the center of Stowe at around 700í as the temperatures continued to drop.† It snowed on and off all the way back to our house in Waterbury (495í), and I found a couple of tenths of accumulation on the snowboard as of 8:00 P.M.† Itís continued to snow all evening, itís still been light, but thereís another tenth of an inch or two on the board now.


Details from the 8:00 P.M. Waterbury observations are below:


New Snow: 0.2 inches

New Liquid: 0.02 inches

Snow/Water Ratio: 10.0

Snow Density: 10.0% H2O

Temperature: 33.6 F

Sky:† Light Snow/Graupel

Snow at the stake: Trace



Saturday, April 28th, 2012



I grabbed a couple of images from the Bolton Valley Live Cam at different times yesterday, one around 6:00 A.M., and another at noon (time code is on the images) so one can see the progression of the snow accumulation during that part of the day around 2,000í:




Iíd say it looked like about 2-3 inches down at that elevation as of noontime, certainly skiable, but I opted to head out to Stowe for turns later in the afternoon based on some of Powderfreakís reports from the week.† Having a good base really escalates the skiing from a borderline rock ski/junkboard day, to a more bona fide winter-style powder day.† I know that thereís still base up in the higher elevations at Bolton, but Stowe has definitely got more offerings, so thanks PF for keeping us apprised of how the base snow has been doing on Mt. Mansfield.† I sent along a couple of shots and some comments about the skiing on Mt. Mansfield yesterday in a post in the NNE thread; Iíve added a couple more below, and the more thorough report is at our website.†






Event totals: 0.3Ē Snow/0.69Ē L.E.


It was snowing last night when I headed off to bed, and itís still snowing this morning, but thereís only been an additional tenth of an inch of snow beyond what was down last night because itís been so light in intensity here in the valley.† The precipitation was just flurries when I made my morning CoCoRaHS report at 6:00 A.M., but itís over to a steadier light snow now, and the radar still shows the precipitation coming in from the northwest and crashing into the spine of the Northern Greens.† Mt. Mansfield has certainly picked up at least a bit of additional accumulation if the radar has been like that all night:




Iím not sure if weíll see any additional accumulation down at this elevation, but itís been nice to get another event into the books, and this falls in as the 45th accumulating storm of the season for this location.† Prior to this, the last accumulating snow here was at the beginning of the month, so this could have gone down as the earliest end to the accumulating snowfall in my six seasons of records, but itís not going to claim that record.† The accumulating snowfall season now stands at 182 days with this event, so thatís in the half-year range, which is at least falls into the average zone. ††Itís still been the least snowy April in that span though with just 0.4 inches so far, and 2011-2012 is still the least snowy season by over a foot, so those dubious honors are still out there.


Details from the 6:00 A.M. Waterbury observations are below:


New Snow: 0.1 inches

New Liquid: 0.01 inches

Snow/Water Ratio: 10.0

Snow Density: 10.0% H2O

Temperature: 30.6 F

Sky:† Flurries

Snow at the stake: Trace



The fresh snow on Mt. Mansfield was really good on Friday when I checked it out, so the whole family headed out yesterday for some more turns.† We didnít kick off the tour until around midday, so the late April sun was certainly starting to have an effect on the consistency of the snow in the lower elevations.† But, itís still only April, and itís not like itís late May or June sunshine weíre dealing with, so the cold air and wind were definitely keeping the warming of the snow at bay above 2,000í and it remained generally wintry in consistency, even in mid afternoon when we were making our descent.† Even though itís been sunny this weekend, the cold air and stiff breezes around here havenít made it feel like itís almost May.† I added a few shots from yesterday below, and the full report is at our website:

Love the story. Thanks for posting all this! I'm thinking of hiking Algonquin again next week. Hoping to see some white stuff but not expecting it though.


Glad you enjoyed the report; the family joined me yesterday for another ski tour at Stowe, and with the sun out, there were some great images of the new snow in the mountains. When we caught our first glimpses of Mt. Mansfield yesterday in the late morning, it was so brilliantly white that everyone in the car was stunned and we had to pull over for some pictures.† I canít really do it justice in a photo, but I added one of those shots below.† I added a few more pictures from yesterday in a post the ski thread, and thereís a link there to some additional images in our website report.† I wouldnít be surprised if there was still snow in the area around Algonquin next week though, itís a big peak at over 5,000í, and Mt. Mansfield still has almost 2 Ĺ feet of natural snow at 3,700í.
