Yesterday was the end of the last storm cycle, so here’s the local snowfall/liquid summary.  Down in Waterbury (495’) we wound up with 15.2 inches of snow comprised of 0.66 inches of liquid and up in the summit area at Bolton (3,150’) they finished off with 36 inches.  Yesterday was certainly the break between systems, with blue skies in the afternoon and mild temperatures.  This upcoming system looks to be another substantial one, with our current NWS point forecast for the valley calling for 3 to 7 inches today, 5 to 9 inches tonight, 3 to 5 inches Monday, and perhaps some more on Monday night.  That sums to 11-21 for this area.  So far the snow from this system has been in the form of small flakes in the 1-2 mm range, so it’s come in quite dense (10.8% H2O) compared to our recent upslope snowfall.

After I cleared the overnight accumulation off the snowboard this morning at 7:00 A.M., there were 1.3 additional inches on it when we headed off to Stowe late this morning.  At that point the snowfall had tapered off to very light in intensity, our temperatures were right around freezing, and one could feel the heat of the sun as the clouds seemed thin.  On Mt. Mansfield and Spruce Peak today we were in the ~1,500’ to ~3,700 elevation range.  It snowed all day, but the flakes were really pretty small in the 1-3 mm diameter range, and we never got into those big upslope-style flakes.  I’m sure the snow still added several inches throughout the day though, and the skiing was excellent.  The temperatures at the base elevations (~1,500’) were around 30 F when we left the mountain this afternoon at around 4:30 P.M., and a couple degrees higher at the house (495’).  The snowfall wasn’t all the impressive at the house when we initially arrived home around 5:00 P.M., but it quickly jumped up this evening.  At times we’ve had a few bouts of larger flakes, but for the most part we’ve been getting those same 1-3 mm diameter flakes that seem typical for this event so far.  There must be a ton of moisture coming down out of the sky right now though, because even with those small flakes, we’re still getting snowfall in the inch per hour range at times.  We’ve also started to get some wind down here at the house over the past hour, so there may be some serious winds in the higher elevations at this point.  Here are some intermediate snowfall observations from this evening:

 

Time – Snow on board

5:00 P.M. – 0.0”

6:00 P.M. – 0.7”

7:00 P.M. – 1.8”

The density of the snow we received between 5:00 P.M. and 11:00 P.M. was exactly the same as the previous batch that fell today at 8.4% H2O.  The snow is certainly quite dry, but the flakes are still relatively small so there aren’t any incredible accumulation rates.  The event has put an additional 0.76 inches of liquid into the snowpack so far however.

It appears as though we got more wind than snow last night, so based on my measurements that would suggest at least 1.1 inches of wind at our location.  In all seriousness though, it did blow much of the night, based on what I heard and what I saw this morning.  We’re quite sheltered at our location, and even we had a little drifting, so I suspect the mountains got a bit of a blast.  At 10.9% H2O, the overnight round of snow was even a little denser than the stuff we received throughout the day yesterday (8.4% H2O), and the wind may have contributed to that.  With this more substantial density snow (vs. the Champlain Powder™ upslope variety) we’ve now attained our highest measurement of the season at our back yard stake (29 inches).  The snow depth in the yard has been slow to increase throughout this system, since I suspect the new dense snow has simply been crushing the 2-4% H2O snow from the last storm cycle that lies underneath it.  I think that the underlying snow is pretty compressed now though, because the snowpack seems to be rising.  My standard snow gauge only goes up to 30 inches, so this evening I’ll probably install my longer four foot one.  If we get some upslope on the back of this event as the NWS suggests, it will probably overtop my regular gauge.

 

In terms of the mountain totals at the resorts, it’s getting a little tough to separate out this system’s snowfall from that of the previous one, since for many places there was only a brief lull and their reports are by the day, not the storm.  It looks like most of the resorts in the northern half of the state are past the 1-foot mark for this individual event at least.  Bolton Valley is indicating 52 inches from the two events so far, so with the first event at 36 inches, that would suggest 16 inches from this one for now.  I only had time to estimate the storm totals for some of the Northern Vermont resorts, but here’s what the totals appear to be, based on the information from their websites.  The list is north to south along the Green Mountain spine:

 

Jay Peak:  14”

Smugg’s:  13”

Stowe: 16”

Bolton 16”

Mad River: 24”

Sugarbush: 18”

Summary:  17.4” snow total in Waterbury (495’) as of 10:00 P.M. EST

 

Monday, February 23rd, 2009:  8:00 P.M. update from Waterbury, VT

 

New Snow:  4.7 inches

Liquid Equivalent:  0.18 inches

It snowed some today in Burlington, but visibility wasn’t all that low and I could see that it was really cranking in the mountains.  We also picked up several inches during the day here in Waterbury, which brought us easily over a foot of accumulation for the event.  I haven’t run the snow thrower yet for this storm, so blasting through the 3 to 4-foot berm at the end of the driveway and getting up to the garage was even a challenge for the Subaru.  Having the snow cascading over the hood and up the windshield is always fun though.  Over the past few hours the snow has really come on at a rate of 1-2”/hr in the form of huge, fluffy, upslope flakes that are settling as that sub 4% H2O Champlain Powder™.  I’m surprised that there aren’t stronger echoes on the local radar with the snowfall rates we’re getting, but I’ve made some intermediate snowfall measurements from the board after the 8:00 P.M. clearing:

 

Time – Total snow on board

8:00 P.M. – 0.0”

8:30 P.M. – 0.8”

9:00 P.M. – 1.5”

9:30 P.M. – 2.0”

10:00 P.M. – 2.9”

 

I thought that the snowfall was slowing down a bit after 9:30 P.M., but then it seemed to go nuts again not long before I went out to check the snowboard at 10:00 P.M.  The 0.9 inches in that half hour period certainly suggests it came on strong.

 

As of earlier this evening, snow totals in the local mountains were already pushing past 5 feet over the last several days, so apparently February is trying to make up for its slow start.  With the way it’s currently snowing around here, I suspect totals could be close to 6 feet by tomorrow.  Here are some of the local resort snow totals for the two combined storms, listed north to south along the Green Mountain spine:

 

Jay Peak:  61”

Smugg’s:  49”

Stowe: 49”

Bolton 61”

Sugarbush: 62”

 

This storm has already reached 17.4 inches of accumulation down here in the valley and bumped the one before it (15.2 inches) into second place.  Our valley total for the two events is thus 32.6 inches and counting.  In terms of snowpack, this event has brought the snow at our stake to its deepest for this season at 33 inches, and as of this evening the snow depth at the stake on Mt. Mansfield has also reached its season high at 86 inches.  If the winds in the mountains have settled down and the snow is falling like it is down here, the skiing should once again be off the hook tomorrow.

Humidity:  78%

Dew Point:  5.7 F

Barometer:  29.91 in. Hg

Wind:  0-5 MPH

Storm snow total:  18.2 inches

Storm liquid equivalent total:  1.15 inches

Current snow at the stake:  33 inches

Season snowfall total:  164.5 inches

 

Our snowfall tapered off down here at around midnight after some fairly heavy upslope snowfall; here are some intermediate accumulations from last night at the house:

 

Time – Total snow on board

8:00 P.M. – 0.0”

8:30 P.M. – 0.8”

9:00 P.M. – 1.5”

9:30 P.M. – 2.0”

10:00 P.M. – 2.9”

11:00 P.M. – 3.6”

12:00 A.M. – 3.7”

 

That brings our total for this event to 18.2 inches, and our total for the back to back storms is 33.4 inches.  As I suspected, some of the mountains have now hit six feet of accumulation from the last six days of snow.  My daily email from Bolton Valley this morning had this to say:

 

Six Feet of Snow.

 

“Looking back at the log we keep of snowfall totals for the year I can hardly believe the last six days. It seems as if I am dreaming. We have measured snow of a foot or more on four of the last six days. We have a six day total of six feet. That's taller than most people. That's two yards of snow.”

 

Here are some of the two-storm totals for local areas on the Green Mountain spine, listed north to south:

 

Jay Peak:  68”

Smugg’s:  54”

Stowe: 52”

Bolton 72”

 

Our back yard stake is now at 33 inches as of this morning, and the Mt. Mansfield stake is at 86 inches as of yesterday evening.  It will be interesting to see if the Mansfield stake report goes up with last night’s accumulation or down due to settling when they check it this evening.  For now here’s the current snowpack plot for our stake and Mt. Mansfield’s:
