On the UVM campus in Burlington today we had light snow until ~11:30 A.M., then I noticed some ticks on the window and the precipitation was light sleet, and finally a bit after noon the precipitation was over to a few spits of rain. There didn’t appear to be much going on during the early afternoon, but as time went on light rain began to fall again. I left Burlington at around 5:00 P.M., and as I walked over to the UVM parking garage the precipitation was light rain. I couldn’t tell if it was freezing rain or not during my walk, because the temperature felt borderline, but a light glaze had formed on untreated paved surfaces, and there was a notable crust on the snow. Treated surfaces were just wet. I got to my car and the temperature read 32 F, right at the freezing point.
I pulled out of the parking garage and the rain immediately began to freeze on my windshield and obstruct my vision, and it was touch and go for a moment there as to whether I’d have to pull over and let the car warm up as I kicked all my defrosting elements into high gear. The defrosters kicked in within a few moments, so I was on my way down I-89. Through the Burlington area the precipitation was just light rain, and the car thermometer stayed at 32 F. Interestingly, as I approached Williston the temperature rose to 33 F and then 34 F, but the precipitation (presumably following temperatures higher in the atmosphere) seemed to simultaneously be going in the other direction as it started turning to sleet with what looked like an occasional flake of snow. The temperature remained at 34 F through Richmond, Jonesville, and even Bolton, and the precipitation seemed to fluctuate between the light rain, or the light sleet with occasional flecks of snow. I was amazed that the temperature had stayed at 34 F all the way into the mountains, but finally as I approached Waterbury and the Washington/Chittenden county line, things began to change again. The precipitation changed over to all sleet, then snow began to mix in, and finally about a mile before I got the house, the precipitation was entirely over to moderate snowfall. In that same span the temperature dropped from 34 F down to 33 F and 32 F, and finally when I got to the house at around 5:30 P.M. the house thermometer was reading 30.7 F. I was once again amazed at the ability of the Green Mountains to separate the weather.
On the snowboard I found 1.6 inches of accumulation, which was snow on the bottom, and then some sleet, and then a trace of the new snow that was falling on top. I’d cleared the snowboard at 6:00 A.M., and my wife indicated that we’d had an additional 0.9 inches of snow as of 10:00 P.M., but she’d also said that there was some sleet falling at that point. The 0.9 inches of snow didn’t seem to be squashed down too hard by the sleet, and it fact it didn’t seem like there was all that much sleet in there, but there clearly was a good dose of it because the 0.52 inches of liquid equivalent in there spoke of some serious density in just 1.6 inches of accumulation. Assuming the local mountains did at least as well as we did, the 0.68 inches plus of liquid are going to be good for building the snowpack.
The moderate snowfall continued while I worked on my observations and ate dinner, so I took a couple of intermediate depth measurements off the snowboard:
5:30 P.M.: 0” snow total
6:00 P.M.: 0.3” snow total
6:30 P.M.: 0.5” snow total
So the snowfall seemed to be in the range of ~0.5”/hr during that period, but since then it has let up to somewhere between light snow and flurries.
