NVT is looking good no matter which model you look at. BTV afternoon AFD mentioned potential for widespread 12+ just from the synoptic snows, then the upslope machine kicks in through late week.

 

I saw that:

 

STILL A LITTLE FAR OUT IN TIME TO HASH OUT ALL THE FINER MESOSCALE DETAILS OF THE STORM IN REGARDS TO QPF/SNOW AND EAST/SOUTHEAST UPSLOPE/DOWNSLOPE POTENTIAL ALONG THE GREEN MOUNTAIN SPINE AND WHITE MOUNTAINS...BUT EARLY INDICATIONS ARE THAT THE NORTH COUNTRY WILL SEE A SIGNIFICANT LATE SEASON STORM WITH UPWARDS OF A FOOT OR MORE OF SNOW POSSIBLE THROUGH TUESDAY NIGHT. STAY TUNED.

 

Let’s hope that potential persists.

BTV's map... winter storm watch out.

 

I generally try to archive the BTV Storm Total Snow Forecast maps here and for my weather pages, and after a quick look back, I haven’t seen one this year with that much 14-18” color spread up in this area:

 

 

Winter Storm Watches are up everywhere on the BTV advisories map except the far west out toward the lakes:

I checked our point forecast and it’s pretty impressive – with that 10-20” summed through Tuesday night followed by more periods of snow:

 

 

 

Snowfall is current 32 inches behind average here, but this week could really help move it along if the forecast is correct.

 

 

Monday, March 18th, 2013

 

 

The updated maps from BTV are out – most Winter Storm Watches were converted to Winter Storm Warnings, there’s a bit more emphasis on higher snow totals in a stripe down the center of the state proximal to the spine of the Greens, and some of that 18-24” shading has appeared in parts of North-Central Vermont:

 

 

 

 

I was checking out our BTV NWS point forecast earlier, and these may be overdone of course based on some of the discussion I’m hearing, but impressive numbers nonetheless summing to 14-26”.  I’m pretty sure that’s the highest potential I’ve seen for a 36-hour period here this season.  The upslope is always a wild card, but a low sitting and spinning like that seems to play out well along the spine.

 

 

 

Copies of the latest BTV NWS maps – Winter Storm Warnings expanded a bit and accumulations were adjusted some as well:

 

 

 

 

Tuesday, March 19th, 2013

 

 

Event totals: 3.8” Snow/0.35” L.E.

 

I looked out around 5:30 A.M. and estimated 3-4” of snow on the snowboard, and that was in the ballpark because at 6:00 A.M. CoCoRaHS observations time the depth was at 3.8”.  I could tell immediately from my cores that this stuff was fairly dense, and indeed it came in at a synoptic-style 9.2% H2O.  There was actually some graupel in among the flakes falling at the time, and I’d describe the snowfall rate as somewhere in the ½ to 1 inch per hour range, so it went down as snow, but not heavy snow.  As of 6:30 A.M. there’s another 0.3” on the board, and the rate of snowfall has definitely slowed down since the earlier observations.

 

There’s no change that I can see in the BTV weather advisories map relative to the last version, but on the storm total snow forecast map they’ve got a more general 10-14” for the mountain areas in the northern half of Vermont, with any spots of 14-18” pushed to the south.

 

 

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

 

New Snow: 3.8 inches

New Liquid: 0.35 inches

Snow/Water Ratio: 10.9

Snow Density: 9.2% H2O

Temperature: 27.3 F

Sky: Snow/Graupel (2-6 mm flakes)

Snow at the stake: 5.0 inches

 

 

I looked at the early reports of accumulations for the Vermont ski areas – a few resorts have yet to report in, but it looks like numbers are currently topping out in the 6” range up north, and the 8-9” range down south where things started up a bit quicker.  North to south listing is below:

 

Jay Peak: 6”

Burke: 5”

Smuggler’s Notch: 2”

Stowe: 4”

Bolton Valley: 6”

Mad River Glen: 6”

Sugarbush: 4”

Bromley: 8”

Stratton: 8”

Mount Snow: 9”

 

 

I took a 7:00 A.M reading off the snowboard and there was 0.5” down, so snowfall is right around that ½”/hr range.

 

 

Event totals: 9.7” Snow/0.83” L.E.

 

We headed to Stowe today, and not surprisingly, the turns were great.  When we left at the end of the day, I was generally getting consistent measurements of 12-13” for snow depth on the terrain of the Mountain Triple – although that sounds a bit higher than what PF reported.  A great day to be out on the mountain; of course there’s nothing like midweek at Stowe, especially when it’s dumping.  A few shots from today are below:

 

 

 

 

We arrived home to find 5.9” of snow from today’s activity, so at least around here it doesn’t look like there were too many issues with the valleys being able to accumulate snow during the day.  In the latest BTV advisories, I see that some warnings have disappeared from off to the south, and indeed there are some notable differences in the latest storm total snow forecast map – the numbers seem to have gone down in the Adirondacks:

 

 

 

I don’t think there’s going to be any trouble reaching the 10-14” total that they’ve got for us on the latest map, especially since we’re passing a foot as of 9:00 P.M. and there’s still a steady snow out there.  This event has definitely been very helpful in making up on the dearth of season snowfall, bringing the season total back up above 85% of average.

 

North to south listing of available snowfall totals from the Vermont ski areas with afternoon updates are below – generally 10-12” at the northern areas and 12-15” at the southern areas as of closing:

 

Jay Peak: 10”

Smuggler’s Notch: 12”

Stowe: 10”

Bolton Valley: 10”

Mad River Glen: 12”

Sugarbush: 7”

Pico: 11”

Killington: 11”

Okemo: 12”

Magic Mountain: 15”

Stratton: 13”

Mount Snow: 14”

 

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

 

New Snow: 5.9 inches

New Liquid: 0.48 inches

Snow/Water Ratio: 12.3

Snow Density: 8.1% H2O

Temperature: 32.4 F

Sky: Moderate Snow (1-5 mm flakes)

Snow at the stake: 9.0 inches

 

 

Event totals: 12.9” Snow/0.93” L.E.

 

The snowfall has been running at a bit more than ½”/hr over the 6 hours leading up to 11:00 P.M., with another 0.4” down as of midnight.  The snow has definitely dried out to a more upslope-style consistency.

 

Details from the 11:00 P.M. Waterbury observations are below:

 

New Snow: 3.2 inches

New Liquid: 0.10 inches

Snow/Water Ratio: 32.0

Snow Density: 3.1% H2O

Temperature: 28.9 F

Sky: Moderate Snow (2-12 mm flakes)

Snow at the stake: 12.0 inches

 

 

Wednesday, March 20th, 1013

 

 

Event totals: 13.9” Snow/0.98” L.E.

 

Another inch of snow fell overnight, and there were still flurries falling during this morning’s observations.  The point forecast here suggests that “Powder Week” continues:

 

 

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

 

New Snow: 1.0 inches

New Liquid: 0.05 inches

Snow/Water Ratio: 20.0

Snow Density: 5.0% H2O

Temperature: 24.1 F

Sky: Mostly Cloudy, Flurries (1-2 mm flakes)

Snow at the stake: 12.5 inches

 

 

Mountain storm totals as of this morning - north to south listing of available snowfall totals from the Vermont ski areas are below.  Numbers seem to generally be in the 14-16” range with a few standouts:

 

Jay Peak: 26”

Burke: 15”

Smuggler’s Notch: 16”

Stowe: 14”

Bolton Valley: 15”

Mad River Glen: 19”

Sugarbush: 15”

Pico: 16”

Killington: 16”

Okemo: 16”

Bromley: 16”

Magic Mountain: 15”

Stratton: 16”

Mount Snow: 18”

on and off strong snow showers in BTV. Big wet flakes. Stunningly pretty snow.

 

Boy, it’s really come on in the past few minutes here at UVM with visibilities dropping down around 1/3 of a mile – looks like a few 35 db echoes popping up:

 

 

I’ve got the web cam running at the house, and I’ve been occasionally checking on snowfall there, but it’s been just flurries with no accumulation so it almost felt like this snow was hitting a wall at the Greens.  It seems like the greater intensity of the snowfall has finally started to push eastward a bit though because I’m starting to see the first signs of accumulation on the deck.  It’s definitely snowing on the Bolton Valley Live Web Cam – looks pretty vigorous up there.

 

 

As of this afternoon’s Co-op data, snowpack at the Mt. Mansfield Stake has gone above average for the first time in about a month:

What a freakin' day... It is absolutely dumping out right now too as the upslope machine gets turned on.

Best storm up here since December 27th.

 

 

Event totals: 14.8” Snow/1.01” L.E.

 

There was 0.9” of additional snow on the snowboard when I got home today, and the 0.03” of liquid in the core brings that parameter past the one inch mark.  There are another couple tenths of an inch of snow on the board as of the 6:00 P.M. clearing, and with the dearth of larger storms this season, this one is actually within a half inch of topping the storm list.

 

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

 

New Snow: 0.9 inches

New Liquid: 0.03 inches

Snow/Water Ratio: 30.0

Snow Density: 3.3% H2O

Temperature: 31.3 F

Sky: Light Snow (1-8 mm flakes)

Snow at the stake: 11.5 inches

 

 

Thursday, March 21st, 2013

 

 

Event totals: 15.0” Snow/1.01” L.E.

 

Yesterday evening’s additional 0.2” is all to report for the overnight accumulation.  It was interesting to hear Roger Hill talk about the snow showers persisting through the weekend in his early broadcast – he didn’t seems as heartened by that thought, but from a snow perspective, more clouds are generally helpful in preserving the powder.  Apparently there is a convective aspect to the snowfall we’re getting so afternoons can snow an uptick in precipitation.

 

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

 

New Snow: 0.2 inches

New Liquid: Trace

Temperature: 18.3 F

Sky: Partly Cloudy

Snow at the stake: 10.5 inches

In general, a very solid 12< snowfall across the board.

 

Thanks for alerting me to the map – indeed I noticed a very tight clustering of snow totals for the northwest section of Washington County near me.  There are a couple of reports visible on the map off to the east of my 13.9” on the county line, and in the text listing below, the four highest Washington County reports are all from Waterbury and right in the at 13-14” range.

Event totals: 15.3” Snow/1.01” L.E.

 

Light snow was falling this morning with 0.3” of accumulation on the snowboard.  I could see that the sky was mostly clear off to the east, but overhead and to the west there seemed to be a bank of fairly dark clouds.  The snow was very fluffy and I couldn’t even measure a hundredth of an inch of liquid from the core, so that will have to go down as a trace.  Based on the BTV forecast discussion, this activity continues to be derived from the low that has been sitting in the area all week, so totals will continue to be added to that event.

 

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

 

New Snow: 0.3 inches

New Liquid: Trace

Temperature: 15.6 F

Sky: Partly Cloudy/Light Snow (~10 mm flakes)

Snow at the stake: 9.0 inches

WRF is really cranking out the upslope, especially over the 24 hour period from 8am SAT - 8AM SUN:

 

I know the BTV WRF is often overzealous with the QPF, but hey, that’s pretty cool.  Down at our place in the valley the point forecast sums to 2-6+”, but whatever happens, these events are fun to watch, experience, and document… oh and ski of course.  It looks like powder week could continue even in valleys:

 

 

 

Event totals: 15.6” Snow/1.02” L.E.

 

We picked up a transient tenth of an inch of snow today, which melted in the afternoon, but there’s a new round of activity this evening with snowfall banked up against the spine clearly visible on the radar:

 

 

There’s been 0.2” of accumulation here as of 8:00 P.M. from this round of snow, which has actually made this protracted event the largest of the season.

 

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

 

New Snow: 0.2 inches

New Liquid: 0.01 inches

Snow/Water Ratio: 20.0

Snow Density: 5.0% H2O

Temperature: 27.5 F

Sky: Partly Cloudy/Light Snow (1-4 mm flakes)

Snow at the stake: 8.5 inches

25f and snowing. .5" maybe otg.

 

Yeah, definitely snowing – I just checked around 10:30 P.M. and found 1.2” on the snowboard since the 8:00 P.M. clearing, so snowfall is in the ½”/hr range.  That snow continues to be banked up against the spine per the radar:

 

 

I haven’t really paid too much attention to the forecast, but I just checked and there’s 2-4” in there for tonight; the snowfall I’m seeing out there seems consistent with that:

 

·         Snow showers. Low around 22. West wind around 8 mph. Chance of precipitation is 90%. Total nighttime snow accumulation of 2 to 4 inches possible.

 

The forecast discussion doesn’t seem to play the potential up as much as the point forecast, but I’d say we’ll do better than the valley D-1” if we’ve already had 1.4” here:

 

.NEAR TERM /UNTIL 8 AM SATURDAY MORNING/...

-- Changed Discussion --

AS OF 743 PM EDT FRIDAY...FAVORABLE SETUP FOR OROGRAPHIC SNOW SHOWERS OVERNIGHT. STEEP LOW-LEVEL LAPSE RATES AND ABUNDANT LOW- LEVEL MOISTURE ASSOCIATED WITH WNWLY FLOW AROUND CLOSED UPR LOW OVER THE GULF OF ST. LAWRENCE WILL MAINTAIN EPISODES OF SNOW SHOWERS...WHICH WILL BE MOST PERSISTENT ACROSS THE NRN ADIRONDACKS AND CENTRAL/NRN GREEN MTNS. EVEN THE VALLEY LOCATIONS SHOULD SEE A DUSTING TO AN INCH OVERNIGHT...WITH 1-3" IN THE HIGHER ELEVATIONS.

It looks like Mother Nature came in right around the top of the forecast, with 3.9” overnight here, with more in the forecast through tomorrow.  Up above us at Bolton they’re reporting 7” new, and the Bolton-Stowe stretch seems to be the local hot spot in the Northern Greens for last night’s accumulations.  The north to south listing of available overnight snowfall totals from the Vermont ski areas is below:

 

Jay Peak: 4”

Smuggler’s Notch: 4”

Stowe: 6”

Bolton Valley: 7”

Mad River Glen: 4”

Sugarbush: 6”

Pico: 4”

Killington: 4”

Okemo: 4”

Bromley: 7”

Stratton: 4”

Mount Snow: 4”

 

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

 

New Snow: 3.9 inches

New Liquid: 0.22 inches

Snow/Water Ratio: 18.6

Snow Density: 5.4% H2O

Temperature: 28.6 F

Sky: Cloudy/Flurries

Snow at the stake: 12.5 inches

This is some surprisingly dense snow... it’s cold powder but dense, and looks to have a decent bit of graupel in it or something. I bet we got a good shot of H2O with this overnight. Curious what J.Spin's liquid analysis finds.

 

There was a decent shot of liquid in it (0.22”) but it’s still quite dry at 5.4% H2O – so great quality stuff that should ski beautifully on top of everything that’s fallen this week.  I have to start using the weekly totals provided by the ski areas since we’re out beyond those 72-hour totals, but here’s a north to south list below as of this morning:

 

Jay Peak: 51”

Burke: 23”

Smuggler’s Notch: 28”

Stowe: 27”

Bolton Valley: 28”

Pico: 24”

Killington: 24”

Bromley: 23”

Stratton: 23”

Mount Snow: 24”

Boom. More snow.

 

Excellent – nice to see March making up for lost time earlier in the season – almost up to 90% of average snowfall here with the help of this latest storm.

Event totals: 20.8” Snow/1.27” L.E.

 

We picked up a transient 0.3” of snow yesterday during the day, and another 1.0” overnight.  We’re getting hit with another burst of snow right now though, with another half inch on the snowboard:

 

 

There’s been an additional several inches of snow at the resorts in the past 24-hours; 24-hr and 7-day totals are below listed north to south:

 

Jay Peak: 5”/51”

Burke: 1”/20”

Smuggler’s Notch: 5”/29”

Stowe: 4”/32”

Pico: 3”/27”

Killington: 3”/27”

Bromley: 0”/23”

Stratton: 0”/21”

Mount Snow: 0”/24”

 

 

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

Could we be looking at another powder day Thursday?
I might make the trip up to jay with ruler in hand.

 

Indeed, tomorrow into Thursday looks like the biggest snow potential this week – Mt. Mansfield point forecast for the upcoming days:

 

 

Thus far I haven’t seen that any big accumulations are expected, but when it comes to the Greens you never know.  The GFS, ECMWF, and NAM all show something on the WunderMap®, it probably just depends on whether the Greens make it go to town or not.

 

I’m certainly ready for the next round of snow, but the weekend skiing was fantastic.  I haven’t posted anything yet, but we’ve got full reports from Saturday at Bolton Valley and Sunday at Stowe; even down to the 2,000’ level at Bolton I was getting settled powder depths of around 22 inches above the subsurface in areas that hadn’t been visited since the recent snows.  I’ve added in a few weekend pictures below:
