Snow started just before
06z, and the evaporative cooling dropped it to 23F by then which was the day 3
high. As expected, a secondary surge of colder air dropped it to 12F this morning
with a maximum wind of 16-17 kt. Unfortunately, it seems like the sensor is undercatching
precipitation, recording only 0.11” so far despite 3-4” of snow. There is a
lull in precipitation but it remains overcast. The second round of snow will
move in this evening, but only a few snow showers will be left after 06z. It
temporarily warms up early tomorrow with some sunshine and the northeasterly
winds shift to a downslope northwesterly wind and strengthen, especially with
daytime heating mixing down stronger winds from aloft, but that wind will eventually
push an even colder air mass in for tomorrow night, with the low at the end (Saturday
06z). Skies will clear by tomorrow evening, though the downsloping wind will
prevent ideal radiational cooling.
