Event totals: 2.0” Snow/0.09" L.E.

 

We were up skiing at Bolton this afternoon and snow started up right about 2:00 P.M.  It moved in pretty quickly, especially since we were on the mountain.  There's nothing like riding the lift into the higher elevations just as a storm is ramping up, because it can really make the snowfall intensity jump up quite rapidly.  Visibility was certainly down to ¼ mile at times early on, and by the time we were leaving near 5:00 P.M., it was a steady, heavy snow.  The intensity of the snowfall certainly lightened up as we headed back down into the valley, but there was two inches on the snowboards at the house when I did a 5:00 P.M. analysis.

 

Details from the 5:00 P.M. Waterbury observations:

 

New Snow: 2.0 inches

New Liquid: 0.09 inches

Snow/Water Ratio: 22.2

Snow Density: 4.5% H2O

Temperature: 21.7 F

Sky: Snow (5-12 mm flakes)

Snow at the stake: 20.5"

 

It was definitely snowing hard up there at the mountain; I've added a couple of shots from today below:

Below I've added the updated advisories and total snowfall maps from the BTV NWS.  For changes in the advisories, there wasn't anything apparent in Vermont, but there are some Winter Storm Warnings added down in New York State and a Winter Weather Advisory filled in to the far west.  I don't think there will be any problem reaching the forecast 3-5" here, since there was already 5-6" out there as of 9:00 P.M. and the snow has been running close to the 1"/hr range.  Snow growth seems very good (5:00 P.M. analysis was 4.5% H2O) so that's presumably helping with the accumulation.

Yeah J.Spin... at least a solid 5" through 9pm and been snowing hard ever since.  The radar has only improved since then.  More rare SW upslope flow occurring...Spine making it happen.

These shots were from before the recent increase in radar echoes.  Its really coming down out there.

When the yellows show up on the radar, that's typically a good sign with regard to snowfall.  That's cool that it's SW upslope flow that has been helping along the spine, we'll definitely take it.  It's sort of about time though; eventually things are going to happen along the spine when you've got a permanent 4,000' lifting mechanism in your back yard.  If the mountains are doing better than us, then the slopes should be fantastic tomorrow.

 

I've got the J&E Productions Live Web Cam running:

I've got over 6" now.  Ripping over 1" per hour even down here.  When we get good orographic snows, and the composite radar has pockets of over 30dbz, that's my barometer for a good event.  Those radar levels can indicate 2-3" per hour in the high elevations, like the ski areas.  Time for bed.

Event totals: 7.2” Snow/0.28" L.E.

 

It's not too surprising with the way it's been snowing that the BTV NWS added some additional Winter Weather Advisories along the spine:

The additional snow was mentioned in the forecast discussion:

 

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...

CURRENT OBSERVATIONS AND RADAR PRESENTATION HOWEVER NOW INDICATING SOME UPSLOPE COMPONENT TO THE FLOW OCCURRING ALONG THE WESTERN SLOPES OF THE GREEN MOUNTAINS (FROUDE NUMBERS INDICATING BLOCKED FLOW). THUS DID INCREASE TOTAL AMOUNTS ALONG THE WESTERN SLOPES AND ALONG THE SPINE OF THE GREEN MOUNTAINS...AND ADDED THEM TO THE WINTER WEATHER ADVISORY. HEADING INTO THE NIGHT...WILL SEE A GRADUAL DECREASE IN SNOW COVERAGE AND INTENSITY FROM WEST TO EAST. TOTAL AMOUNTS OF 1-3" ACROSS NORTHERN NEW YORK...3-7" ALONG THE WESTERN SLOPES AND SPINE OF THE GREEN MOUNTAINS...AND 2-5" ACROSS THE REMAINDER OF VERMONT EXPECTED.

I was in Stowe last night for the Dark Side of the Mountain show at the Rusty Nail and I am convinced it is a different world over there! Wow what a scene and the snow was coming down hard when I arrived. The depths were of course impressive too. It was a Norman Rockwell scene.

Wow:  6.5" here with only 0.20" of water.  (no board clearing till this morning).

 

That's 32.5:1 stuff.  Unreal fluff.

 

I really didn't see that coming--both the snow amount or the ratios.  I was banking on 3" or so...

6.4" down here in the valley as well.  Finally made it up to 24" on the ground.

Haha that's awesome... you could've walked to my house. 

 

Great night to come to town, it was some of the most beautiful snowfall evenings this winter.  Just pouring big dendrites.

It was fantastic to see. Are the trees still covered? I was thinking of trying to get some pics today.

Nice!  I saw a report from Fairlee last night of 5"...but it was still coming down at that time.

 

Started the morning with 32" at the stake.  Should see a few inches of settling though.

 

Have to say, that may have been the easiest half-foot of snow I've ever plowed/snow-blowed/shoveled.  Light as a feather!  Makes me wish they were all like that.  ;)

3.2"/0.23" last night. Depth was up to 28"...back down to 26" now at my stake.

Monday into Tuesday looks brutally cold. Lots of -20s and -30s up north and well into the -10s here on MOS. I have a chance at my coldest of the season.

My avg min for the month is currently at -0.1F including the 17.5F from this morning. There's a pretty good bet I pull off my first month averaging a min below zero. I have a slight chance at a monthly avg below 10.0F as well.
