I checked outside around 5:30 A.M. this morning and very light snow was falling at the house.  The air temperature was right around the freezing mark, but there was no accumulation on any surfaces at that point.  When I checked out again at 6:00 A.M. the precipitation was a mix of snow and sleet, and the sleet was coming down quite vigorously.  About a tenth of an inch had accumulated on the snowboard at that point, and I saw accumulations starting to appear along the sides of roads in Waterbury.  The precipitation gradually waned as I headed west toward Burlington, where it’s just cloudy with no signs of precipitation.

 

 

Event totals: 1.4” Snow/0.87” L.E.

 

It sounds like Burlington saw some frozen precipitation today, but I couldn’t tell for sure if we got any on the UVM campus from my checks out the window – it seemed like mostly rain.

 

Leaving Burlington at around 5:00 P.M. the precipitation was definitely just rain, with no obvious signs that there had been anything frozen.  I couldn’t really see what was going on in the darkness outside from my interior seat near the back of the bus, but at some point I started to hear pinging on the roof and it was clear that we’d gone far enough east to get into the frozen precipitation.  Looking at the windshield of the bus I, the huge blobs of wet crystals indicated there was also snow coming down out there along with the sleet.  Even farther east, the pinging had mostly subsided and the precipitation seemed to be mostly snow for a time, but there was also some rain.  It was quite a mixed bag west to east.

 

My first real sense of accumulations was as we approached the Waterbury Park and Ride and I saw that there were actually small snowbanks along the road.  Outside, the mixed precipitation was literally pouring down as an impressive combination of snow, sleet, and rain, and there were a couple good inches of slush in the parking area.  There was an inch or so of accumulation on the car, but as the temperature was in the 33 F range, most of it wasn’t bonded to the windshield and the wipers cleared it off.

 

Back at the house we had a solid coating of dense sleet and snow, which turned out to be 1.3 inches once I measured off the snowboard.  I took a core sample and found 0.84 inches of liquid in there.  After melting down the contents of the rain gauge I found 0.87 inches of liquid for the storm total, so essentially everything that had fallen was still tied up in the frozen accumulation on the board.  The precipitation continued pretty steadily at that point as mostly sleet, and another tenth of an inch of accumulation was put down before it shut off.  As of 8:00 P.M. the sky here is just cloudy and the temperature is hovering around 33 F.

Event totals: 1.4” Snow/0.91” L.E.

 

The extra bit of sleet from yesterday evening and whatever else fell after the 6:00 P.M. observations added an additional 0.04” of liquid. to the event as of this morning, bringing the current total liquid total to 0.91”.  The snow depth at our back yard stake was still at ~1.5 inches this morning, and represents the first time this season that we’ve had more than a trace of snow on the ground at the 6:00 A.M. CoCoRaHS reporting time.  Our temperature was around 34 F, and since temperatures have not really risen since the storm in our area, there’s really been little change in the snow on the ground.  Based on the forecast for the upcoming week, it doesn’t look like this snow will be the start of the winter snowpack, which is good considering we’ve still got several things in the yard to button up for the season.  Since there’s more light available in the morning now due to the recent time change, I was able to get a look at the snow on the ground along the Winooski corridor into Burlington.  The amount of snow on the ground generally falls off as one heads west from Waterbury, but there seemed to be a bit of resurgence in the Richmond area before it finally tapered off altogether at some point a bit past that high point of I-89 in Williston.  There’s no sign of snow in the Burlington area, but paved surfaces are still wet.
