SW-WSW winds 15-25 mph, with higher gusts, along upper elevation mountain ridges. Temps in the 50s to lower 60s, except dropping into the 40s to low 50s in mountain valleys that remain sheltered from gusty winds.

Weather Discussion ( March 15-16 )
Tuesday was a simply delightful day in the mountains, with large day to night temperature spreads now being observed amid mountains valleys ( from a MAX of 76 degrees temps have fallen to 45 degrees, as of 2:00 AM, here in Clintwood ).
Following showers & thunderstorms, which produced 0.54″ of rain during the past couple of days in Clintwood, the drying of air aloft was evident this afternoon with nice blue skies amid the Beeches.
Climb upward out of the deep mountain hollows and it is a mild and gusty night ( windy ) along mid-upper elevation mountain ridges & plateaus.
This is a rare March night when 20-30+ mph winds across high ridges are not accompanied by any substantial wind chill factors.
Even our highest resolution models can not pick up on the large vertical temperature differences occurring across our complex terrain, with large temp differences over short distances and within the lower 1000-2000 vertical feet of the atmosphere tonight ( as of 1:00 to 2:00 AM ).
Following another fast moving morning cold front, with a chance for hit-miss showers and perhaps local thunder in a thin line along-ahead of the boundary, yet another very nice afternoon is expected today.
Mountain valleys are likely to turn frosty into Thursday morning, especially amid the colder locations, as winds calm and another inversion develops amid lower dewpoint air tonight.
Focus then shifts to a cooling trend and the Palm Sunday weekend system, which is looking a little weaker & a little farther east on its track.
The Ensemble MEAN snowfall forecast was still in the 2-3″ range for the Wise gridpoint, with variations from 0″ up to more than 6″ on the 51-Member group Tuesday ( 12z run ).
As always, check back for updates on this late winter-early spring weather system.
