Partly cloudy start, an amazing sunrise…a brief morning shower. Trace is all. A day that featured more clouds than sun, but a pleasant day overall.

Pics today
Amongst the weather group last night, there was some discussion of the possibility of flakes at Spruce Knob this morning. It doesn’t appear that panned out. Models were showing 850s around 1°C/33.8F with pockets of precip through daybreak today.
Temp falls this evening- Northern Canaan site dropping rapidly from 8 pm through 10pm. A 9 degree drop in a half hour, 10.6 in 40 minutes after 8pm. The 3km parameters strongly hinted at the possibility of the light winds remaining up on the high ground. The model also modeled these blips of very low dew points. A tipoff that valleys may drop and hold cold before the return flow eventually scours it out. Which, i believe as you’ll see in tomorrow’s post, cloud cover was the main temp moderation from 1:30am the 15th till daybreak. As temps did not jump to match the high ground
3km Parameters
David Carroll from Virginia Tech and his class out in Colorado, high on the Rockies on the continental divide. Reporting many feet of snow remaining and up to 30′ drifts remain
Cloudy, morning showers, some briefly heavy. Then a 3 hour or so break before a return of showers, and increasing winds. Some thunder, lightning and few reports of hail.
