ALERT For Accumulating Snowfall Beginning Wednesday Afternoon Into Thursday Morning Within NW Flow Upslope Zones Along And Northwest Of The High Knob Massif & Tennessee Valley Divide

Flurries and snow showers will begin developing during Wednesday afternoon and continue into the mid-morning hours of Thursday.  Caution for slick sections on roadways, with accumulations varying from a dusting up to 2″+ .

ALERT For Strong WNW to NW Winds And Bitter Wind Chills Wednesday Into Thursday – Especially Middle To Upper Elevations.  Caution is advised. 

Strong SSE-SW winds will develop Monday into Monday Night well in advance of a strong cold front.  Wind gusts of 25-40+ mph will be common in upper elevations & exposed mid elevation ridges-plateaus.

A strong and steady temperature decline will begin Tuesday Night and continue into Thursday Morning, with steady to falling temperatures expected during Wednesday as low-level moisture begins increasing.  Strong & gusty WNW-NW winds will make conditions feel much colder with dropping wind chill values.

ALERT for a blast of bitter cold with temperatures falling slowly through the 20s Wednesday at the middle to lower elevations along and northwest of the High Knob Massif, through the lower 20s into the 10s at upper elevations.

Expect much colder wind chill values.

NW flow snow showers and flurries are expected by Wednesday PM into Thursday AM on upslope flow.  Accumulations are expected to be light, with greater Great Lake moisture transport farther northeast in central-northern West Virginia into Pennsylvania.

The potential for a more widespread and significant winter storm system is being monitored for January 12-13.  Stay tuned for later updates.
