Event totals: 1.1” Snow/0.43” L.E.


Monday 4/4/2011 6:00 P.M. update:  Snow started around 8:00 A.M. in Burlington this morning, and probably around 8:30 A.M. at the house based on what I saw on the web cam.  It was at times a driving snow in Burlington that was very impressive, and it even started to accumulate a bit in town.  The accumulation topped out at 1.1 inches here at the house, and when I took my 6:00 P.M. observations it had settled down to roughly the ½ to ¾-inch range.  Some rain fell after the snow, and while I pulled 0.24” of liquid out of the snow core, there was 0.43” in the rain gauge so apparently it wasn’t all held in the snow.  As Powderfreak said, the snowpack at the Mt. Mansfield Stake increased to 100” with this event, that’s always a nice benchmark to reach.  The Mt. Mansfield point forecast shows snow chances through Wednesday of this week, then a break, and then more chances at the end of the weekend heading into next week.


Some details from the 6:00 P.M. Waterbury observations are below:

New Snow: 1.1 inches
New Liquid: 0.43 inches
Temperature: 37.0 F
Sky: Cloudy
Snow at the stake: 17.0 inches

I only saw rain in Burlington today, although I could tell that the precipitation was changing over to snow in the mountains as the “wall of white” appeared off to the east.  In the evening around 6:00 P.M. as I was traveling in Waterbury and the precipitation was still mostly rain, but the ice crystals were clearly visible in the drops on the car windshield and I knew the snow line wasn’t too far above us.  I figured I’d see in the morning if things changed over to snow here at the house, but once I started hearing ticks on the window, I knew we’d already gone over.  I looked outside around 9:00 P.M. and we had quite a good graupel storm going on with a couple tenths of an inch of accumulation on the snowboard.  I peeked at the radar and saw that there could be a decent stream of moisture passing through the area, so we’ll see if anything else accumulates this evening.

Event totals: 2.3” Snow/1.48” L.E.


 4/6/2011 6:00 A.M. update:  I thought that the snow was coming down pretty heavily last night when I was able to stick my arm out the back door and watch it get coated within seconds.  We were sort of under the fire hose for a bit there, and I’ve added another shot that I grabbed from the radar before heading off to bed:


This morning the snowboards had 1.2 inches of snow on them, and a core sample revealed that the snow contained 0.29 inches of liquid.  Most surprising was the total liquid that I found in the rain gauge.  For the past couple of days when I’ve been measuring the liquid in the gauge, I keep wondering if I’d somehow forgotten to empty it, because the amount of liquid equivalent has been so substantial.  I brought out a half inch of hot water this morning to melt what was in the gauge, but the massive frozen conglomerate sort of laughed at that attempt and I had to bring the gauge back inside and add another whole inch of hot water to finally melt everything down.  The net result was 1.05 inches of liquid equivalent from the past 24 hours, with roughly an inch and a half of liquid from the event.  I was relieved to see that the 0.43 inches of liquid that I measured yesterday morning wasn’t out of line with what other CoCoRaHS observers had received in the area:


It is interesting to note how many of the observers don’t/didn’t measure snowfall though, so unfortunately the snowfall data become rather sparse:


I’ve been curious about today’s liquid as well, but I did see a 0.89-inch reading over the border in Chittenden County, so I guess about an inch of liquid did actually fall.  In the new snowfall map below, one can see the way the snowfall tapered off to the west with the warmer temperatures – someone ended up with quite a nice shot of snow off to the east in Caledonia County with 5 inches:


The mountain snowfall last night seemed to be in the northern part of the state; I’ve added some of the Vermont ski resort accumulations in the north to south list below:


Jay Peak: 3”

Smuggler’s Notch: 1”

Stowe: 7”

Bolton Valley: 4”

Mad River Glen: 6”

Sugarbush: 6”

Killington: 2”

Mount Snow: 1”


I have to think the Mt. Mansfield Stake will come in well above that 100” mark after last night’s round of snow.  We’ll have to see what the data say this afternoon, but winter just keeps rolling on and setting the spring ski season up for some good turns.


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

New Snow: 1.2 inches
New Liquid: 1.05 inches
Temperature: 29.7 F
Sky: Partly Cloudy
Snow at the stake: 17.0 inches

Thanks for the radar image, J.Spin! That fire-hose band of precipitation would explain what we are finding on the mountain this morning. The Mansfield stake has to be over 100" and I'm going up around 1pm to find out. We had 7" (!) on the 3,000ft snow board and about 3.5" on the 1,500ft board for 24 hour totals. The 7" is an incredible surprise as most of the mountain above Crossover trail (1,800ft-ish) has a smooth 6-7" on it.

I honestly have no idea how Smuggs is only reporting a dusting to 1" overnight. I can see their trail system two miles away. I've got pictures I'll try to post tonight, but needless to say this was a true powder day. There's absolutely no one here either... you'd think we were closed. That doesn't help convince management to stay open another week (everything is open and the base depths are incredible). I didn't cross a track my first 3 runs. It was like going heli or cat skiing but with a lift.

The skiing this morning has been off-the-freakin-hook with every trail covered in an even layer of boot deep snow. It was wet and dense snow yesterday afternoon and evening, then the final 3-4" were drier, upslope style snow.

I think there were more employees and management out there skiing today than actual customers... everyone saying, "this is why we work here."

This winter just will not go down without a fight. Incredible.


I would certainly have gone out for turns today if I hadn’t had stuff to do at work, this is one of those days that was likely to be very much under the radar.  It’s so great that the employees are out there making good use of it, just the way it should be.


Anyway, the stream is back on to some degree, we’ve had steady snow here in Burlington for the past couple of hours.  It’s not accumulating down here, but I have to think it could up in the high country.  Radar below:
