High clouds, dimmed sun. A milder flow aloft, capping stagnant air and cooler air the the valleys.

Sooooooo close…..
The upcoming event later Friday through Saturday a.m with backend upslope…
Over the past 2 days models have trended north with the upper low to our west
Case in point, the modeled upper low on today’s ECMWF run vs the 18th. Minor, but significant …
that said, the transfer to the low to our east is slower, we remain jusssst mild enough for for mostly rain Friday/Friday night before we get the wrap around snows on the backside and Saturday afternoon through Monday. 3-6″ of upslope looks like a good bet for the upslope areas.
Areas near and above 4200- 4500′ and above tomorrow afternoon, tomorrow night, across the Wv high ground remain in the snow threat. A very close setup. Charleston has backed off some on the threat for Snowshoe Friday night and at the moment Charleston puts out a very ODD forecast on the point and click.. read
I’ll highlight Friday night. Rain and snowshowers, becoming all snowshowers after 2am. WIDESPREAD blowing snow, mainly before 8pm…but yet on Friday they say precip becomes all rain after 3pm. That makes 0 sense.
Modeled 850s, basically the Wv high ground off the 3km Nam are near +1 to +2 C, freezing levels come down to 5000-5500. That can be just cold enough to get snow at the surface across the high ground. Will try to post latest model trends today…a trend any milder, lowers snow threat across the highest areas, any trend colder and even a minor trend, increases the high ground snow threat.
Friday afternoon- rain for most. Possibly a trace of ice in eastern Garrett with temps briefly reaching the dewpoint and flirting with freezing. The high ground snow risk still in play in W .
Friday night, rain and a cold rain for most, mid 30s, high ground in Wv, the snow risk is still in play and whatever rain there that occurs transitions to snow predawn Saturday.
Saturday- main precip is gone, wrap around upslope begins during the day and that goes through Monday in a varied fashion, with 3-6″ a good bet across the upslope areas over the duration of approximately 48 hours.
Any changes will be posted.
