My Forecast For Today ( January 28 )
Overnight Into This Morning
Partly cloudy ( some high clouds ). Patchy fog possible along major rivers. Winds becoming S-SW at generally less than 10 mph along mid elevation ridges and plateaus. SW to WSW winds 10-20 mph, with higher gusts, along upper elevation mountain ridges. Temperatures varying from the 10s to lower 20s in colder locations verses rising readings into upper 20s to lower 30s on exposed ridges at mid-upper elevations ( mostly above 2700 feet ). Wind chills in the 10s and 20s ( coldest at highest elevations ).
Partly to mostly sunny. A period of mid-high altitude clouds. SSW-SW winds at 5-15 mph, with higher gusts, below 2700 feet. Winds SW-WSW 10-20 mph, with higher gusts, above 2700 feet. Temps varying from the lower 30s to the lower 40s ( coldest at highest elevations ), with mid 40s possible in downslope sites ( e.g., Pound, Clintwood ). Wind chills in 20s & 30s.
Tonight Into Friday Morning
Lowering cloud bases with flurries and snow showers developing overnight into morning. Turning blustery. Winds SW shifting WNW-NW at 10-20 mph, with higher gusts on middle to upper elevation ridges and plateaus. Temperatures dropping into upper 10s to upper 20s by sunrise to mid-morning. Wind chill factors in the single digits and teens ( coldest at highest elevations ).
Snowfall Forecast For Friday
Upslope Side of Mountains
0.5″ to 2.5″
Downslope Side of Mountains
Dusting to 0.5″
Target snowfall of 1.0″ at Wise, ( +/- ) 0.5″ Error Potential. This implies 0.5-1.5″ possible in the Norton-Wise area. Extremes of a dusting up to 2-3″ will be possible across the area, with greatest snow amounts expected along upslope side of mountains with respect to WNW-NW air flow ( i.e., least snowfall to the ESE-SE from the High Knob Massif and Tennessee Valley Divide ).
