Event totals: 0.8” Snow/0.08” L.E.

Friday 1/21/2011 6:00 A.M. update:  At our location along the
Waterbury/Bolton line we had 0.8 inches of new snow this morning as of 6:00 A.M. observation time.  The snowflakes were all very small, ~1 mm or less, and the snow came in right at 10% H2O (10 to 1 ratio).  I can’t tell how much snow they’ve picked up in Burlington, but I would guess not quite as much because the snowfall, while coming down, is notably less intense than what I saw at home.


Of interest for our area in terms of snowfall is that we are now very close to hitting 100 inches of snow for the season, and since we are only an inch and half away it’s possible we could make it there with this system.  I just ran the numbers, and based on my data, the average date for reaching 100 inches here is February 7th.  We are still 17 days ahead of that date, so certainly ahead of average for snowfall.  For comparison with other La Niña seasons, in the ‘07-‘08 season we reached 100 inches on January 14th, and in ‘08-‘09 it was January 11th, so we are actually not too far off the pace of those two respectable seasons considering we’ve not yet had a big synoptic storm really hit this area.


On that note, in his morning broadcast, Roger Hill indicated that there is the chance for another synoptic storm in the middle of next week after the cold spell, and I see that the guys are talking about it in the pattern thread.


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

New Snow: 0.8 inches
New Liquid: 0.08 inches
Snow/Water Ratio: 10.0
Snow Density: 10.0%
Temperature: 17.2 F
Sky: Light Snow (1 mm flakes)
Snow at the stake: 18.5 inches

Yeah the synoptic portion of these events always gets old quickly, haha. As of 8am here in Stowe it looks like we've got around an inch.

I already know what'll happen... we'll get 1-2" on .1-.2" of QPF, then this afternoon or tonight out of nowhere we'll pull 3" of upslope on a trace amount of liquid. We may end up with similar amounts to some people further south and east when all is said and done, but the actual liquid added to the snowpack will be like a third.

I'm getting antsy for a 1"+ QPF event up here, lol. Still, I shouldn't complain because we seem to be doing quite well for a lack of synoptic storm hits.


Whoops, I just noticed when you quoted my obs that I had heavy snow in there, looks like I just forgot to change it when I pasted it in from precious obs.  It would have been nice if there was a burst this morning, but in actuality the intensity of the snowfall was only light; I changed it in the original post for the records.


But you totally nailed it Scott in terms of how things have gone; snowfall numbers may end up similar thanks to upslope, but liquid will be less.  No complaints of course with the way the skiing has been, we'll just want synoptic snow to keep building that base for the spring.  Roger Hill was optimistic this morning about the potential to get something a little more substantial in terms of synoptic snow out of next week's system, but we'll just have to see how it goes.


In terms of snowfall with this event, here in Burlington it snowed enough this morning subsequent to my arrival that it actually produced a decent coating on the cars (perhaps an additional inch?) so I’m anxious to see if we got enough at home to hit the 100-inch mark.  Either way, we’re doing pretty well and have the potential to end up with a big season depending on how the rest of this month and February through May play out.  I just checked, and amazingly, we’re only about 6 to 7 inches behind our “record” ‘07-‘08 pace for snowfall.  We hit 100 inches earlier in that season, but January ‘08 was actually pretty weak for snowfall (and we have been gaining on it hard this season, even without getting nailed by synoptic storms).  We are actually less than 2 inches away from having the snowiest January in my records; I was totally stunned to see that based on where the big snows have been.  To a large degree, the ‘07-‘08 season was really set up by a big November-December combo (86.0 inches) and was solid, but not outrageous beyond that.  We had hardly any snow in April that season either (the last three have sort of gone that way) so a decent April would help out too.  If November hadn’t been such a dud for snowfall this season, we would be close to record pace for snowfall in terms of what I’ve seen at my location over the past 4 seasons.



Event totals: 1.5” Snow/0.16” L.E.

Friday 1/21/2011 6:00 P.M. update:  There was another 0.7 inches of snow on the board as of 6:00 P.M. today, still fairly dense stuff comprised of small flakes.  I was out clearing the driveway of this week’s snow and we had that same stuff that Allenson reported – snowing with the stars out.  It was intense enough that there were another couple of tenths when I checked the board about an hour or so ago, but activity generally looks pretty light out there.


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

New Snow: 0.7 inches
New Liquid: 0.06 inches
Snow/Water Ratio: 11.7
Snow Density: 8.6%
Temperature: 15.8 F
Sky: Light Snow (1 - 4 mm flakes)
Snow at the stake: 18.5 inches
