jspin/p.freak how does up slope look verbatim for 12z friday on euro in greens....potential....too dry?

 

PF usually likes to see 80-90%+ in terms of humidity as I recall – I see some humidity up toward that level on the GFS and ECMWF, but it also moves out pretty quickly.  PF is the expert on that stuff, so we’ll see what he thinks, but the ECMWF snowfall plot on the WunderMap® certainly has that upslope look for the second half of Thursday.

 

BTV NWS says the following in their discussion:

 

SYSTEM EXPECTED TO IMPACT THE REGION ON WEDNESDAY BEGINS TO EXIT NEW ENGLAND THURSDAY. MAINTAINED CHANCE PRECIPITATION PROBABILITIES FOR THURSDAY AFTERNOON...THOUGH HAVE GONE WITH SLIGHT CHANCE PRECIPITATION PROBABILITIES FOR THURSDAY AFTERNOON/EVENING ALONG EASTERN-FACING SLOPES WHERE UPSLOPE SHOWERS MAY CONTINUE TO LINGER. NORTHERLY FLOW THURSDAY NIGHT ALLOWS 850MB TEMPERATURES TO FALL INTO THE -8 TO -10C RANGE. HIGHS ON THURSDAY REACH INTO THE 40S WITH LOWS IN THE 20S TO AROUND 30 IN THE CHAMPLAIN AND SAINT LAWRENCE VALLEYS. WEAK HIGH PRESSURE THEN BUILDS IN FOR FRIDAY WITH TEMPERATURES A COUPLE OF DEGREES COOLER THAN THURSDAY.

Event totals: 0.2” Snow/Trace L.E.

 

At some point last night we picked up a couple tenths of an inch of snow, which appears to be the first salvo from the low pressure moving to the southeast out of Canada.  Additional precipitation is expected from this system through tomorrow.

 

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

 

New Snow: 0.2 inches

New Liquid: Trace

Temperature: 30.2 F

Sky:  Cloudy

Snow at the stake: Trace

There was no snow accumulation to report from the house this morning, but I just noticed that it’s actually snowing lightly here in Burlington at the moment.

 

 

I was down at the Burlington Waterfront all morning, and it snowed the whole time, although there was no accumulation due to marginal temperatures.  The snow let up during the middle of the day, but then picked up again toward evening.  Here at the house we’ve had continued snowfall through the evening as well.  It hadn’t been accumulating earlier, but the flakes are pretty large now (up to ~3/4” diameter) and the temperature has dropped enough that it’s starting to get white on some surfaces.  I checked the snowboard and it had 0.2” of slush snow on it as of ~8:00 P.M.

Event totals: 0.8” Snow/0.16” L.E.

 

The overnight snow totaled 0.6” at the house, and 0.03” of liquid was pulled out of the core, but it was one of those situations where rain/slush had frozen on the snowboard – not the easiest cores to produce with perfect accuracy.  The rain gauge in winter mode collected 0.06” of total liquid from the rain and snow, so the core is probably in the ballpark for the portion of the precipitation that didn’t melt on contact.  It looks like the next snow threat affecting this area would be on Sunday, with some potential during the midweek period next week as well.

 

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

 

New Snow: 0.6 inches

New Liquid: 0.03 inches

Snow/Water Ratio: 20.0

Snow Density: 5.0% H2O

Temperature: 28.0 F

Sky: Partly Cloudy

Snow at the stake: Trace

 

 

The views of the fresh snow in the mountains today are fantastic, especially with the mostly sunny skies.  The visible snow line is at ~2,000’ from what I can see here in my office.  The president flew in today, so it’s great to have the mountains looking picturesque:

Pictures of the president’s arrival/snow in the Greens are available at the above link.

 

We had a nice round of snow last night that whitened up the Green Mountains from about the 2,000' level on up, so it was a picturesque backdrop for the president's arrival today.  The attached link has some cool images.

We headed out to Stowe with the boys for a couple hours of skiing yesterday afternoon – the morning seemed somewhat gray with the snowstorm passing to the south, so we weren’t sure if surfaces were going to soften, but the sky cleared out to blue and the weather was excellent.  Temperatures were probably similar to when we were last there on Sunday, in the 40s F, but it was the polar opposite in terms of cloud cover.  The clear weather and the fact that it was the last lift-serviced Saturday, really brought out the visitors and the main parking lot was pretty full.  The recent snow from the end of the week was certainly around – we spotted it in the alpine on our way to the resort, you could get into it when you popped off the beaten path while skiing, and you could even see it preserved in shady spots all the way down to the village elevations.  We may head out this afternoon for a few more runs, but we’re playing it by ear to see if the temperatures rise sufficiently – with the incoming snow for tonight, it doesn’t look like it’s going to clear out the way it did yesterday.  I added a couple of shots from yesterday below, and the full report is at our website.

 

 

 

 

 

Collection of my March snowfall data is complete, so I’ve updated the ‘11-‘12 monthly snowfall graph for this location and added it below:

 

 

I’ve left the vertical axis on the graph at a scale that more typically accommodates the monthly snowfall values I’ve seen here (often at least one of the midwinter months hits that 50 to 70-inch range) so it provides some perspective on where the season sits relative to some of the previous ones out of these last six.  With March coming in well below average for snowfall, it slides in with all the other below average monthly totals for the season, except October and November, which actually were about average.  The plot does have a nice symmetrical, pyramidal shape at this point though, topping out when the climatology says it should be coldest.  As of April 1st, snowfall here for this season is at 69.7% of the mean calculated from my past five seasons worth of data, and is outside the one standard deviation mark at -1.113 S.D.  The snowfall of 114.8” through April 1st is still holding fairly close to the ‘09-‘10 season total, which was only 119.6” as of this date.

Nice pics J.

 

Thanks for the comments guys, glad you enjoyed the shots – I’ve added a couple more from Sunday below.  Mom and the boys wisely opted out, but I decided to tag on a quick afternoon visit to the mountain with some grocery shopping and do a couple runs.  The snow softened only marginally in the lowest elevations, so it was nothing like the previous few days; one definitely needed edges on the skis, which is generally not a good sign.  Although not uncommon for a cool, cloudy spring day, the heinous snow surfaces led to an inauspicious ending to Stowe’s lift-served season, and folks that had purchased tickets were certainly going for vouchers/refunds to some degree.  A sign about returning tickets was prominently displayed at the outside ticket area at the Mansfield Base Lodge, also a tip off about the snow surfaces.  Although conditions were generally crummy, it did snow a bit and that was nice to see.  I noticed that some snow is finally shown wrapping back into the area on the latest ECMWF though for the start of next week, so we’ll have to see what that does.  The full report from Sunday is at our website.
