Wintry Scene In Wise County
Much more snow and cold air have occurred before, of course, at this time of year, but this blast was notable for a transition which drove pleasant 50-60+ degree temps on November 11 into the 10s and 20s during November 12 ( producing the first 0 to 10 degree wind chills of the season - Ouch! ).

While up to 35 degrees of temperature difference was noted on the automated thermometer, which tends to run 1-2 degrees above the official NWS MMTS system, actual feels-like conditions were 40-50 degrees colder during the afternoon of November 12
verses November 11 when factoring in wind gusts!

While 1" or less of snow depth was reported across much of the area, especially below 2000 feet, 1-2" occurred along the corridor from Kingdom Come State Park to Breaks Interstate Park on
Pine Mountain ( along the VA-KY border ).

NASA visible images were interesting as the cold air began to
push into the southern Appalachians, with vertically raised clouds highlighting both the mountains and eroded calcareous cores of the Powell Valley Anticline, along the High Knob Landform, and the Sequatchie Valley Anticline in southern Tennessee.

The bottom of this temperature slide was reached with 10-15 degree MINS being reported at highest elevations into November 13 and across mid-upper elevation valleys during AM hours of November 14 ( valley mins often tend to be a day or so later than ridges following strong cold air advection ).
Valley temperatures dropped into the 10s to lower 20s again
into early hours of November 15 ( with increasing high clouds ).

Long Ridge of Sandy Ridge
Late Season Colors Linger Around Mountain Pond
Although subject to tough conditions during the orographic forcing season of November-April ( or October-May in some seasons ), Long Ridge is like many places along the Tennessee Valley Divide and rests amid the thermal belt zone where night-time temperatures tend to be milder than both valleys below and ridges above this elevation zone.
**The Thermal Belt being a favored elevation zone
for Orchards, Wineries, and any frost sensitive crops.
