My Forecast For Today ( January 18 )
ALERT For Dangerously Cold Conditions Monday & Tuesday With Bitter Temperatures and Wind Chills Amid The Coldest Air Mass Since Last February
Once Air Temperatures Drop Below 20 degrees In Norton-Wise tonight, they may not rise above 20 degrees ( for any length of time ) until Wednesday. They will certainly not rise above 20 degrees for those living on northern slopes. Snow cover of 1-3″, or more in spots, will make conditions colder within locations having snow on the ground.
***Remember to dress warmly and to plan not to be outdoors longer than necessary. Check on our elderly residents, take measures to protect pets ( e.g., horses, dogs, cats etc…need shelter from the cold & wind as well as ice free water ).
Temperatures at the High Knob Lookout will drop below zero tonight, rise only into single digits Monday and go below zero again into Tuesday Morning. Wind Chills will be EXTREME. Travel & visitation to there is not recommended.
High country lakes will freeze over during this event, as will many ponds & slow running creeks. Caution Is Advised as ice may not become thick enough to walk across safely.
Overnight Into This Morning
Turning bitterly cold. Scattered snow showers & flurries diminishing overnight into the predawn. Temperatures plunging to -4 to 8 above zero into the overnight-morning hours ( somewhat “milder” in valleys leeward of the High Knob Massif and Cumberland range ). Wind chills varying from 5 above to -10 below zero across mid elevation ridges & plateaus, with -10 to -25 degree below zero wind chills in upper elevations above 3000 feet.
*Note that the air will become so bitter than any passing cloud can still generate flurries today; although, I will call for mostly sunny skies after any morning clouds evaporate amid drying air.
Mostly sunny & bitter. WNW winds 5-15 mph, with higher gusts ( especially at higher elevations ). Temperatures in the single digits and teens ( topping 20 degrees officially only in “milder” snow-free valleys amid river basins of the Clinch, Powell, and Holston ). Bitter wind chill factors of from 0 to 12 degrees at elevations below 2700 feet, and from 0 to -15 below zero across upper elevations.
Tonight Into Tuesday Morning
Mostly clear in the evening with some increasing clouds overnight into morning ( especially in upslope locales ). Bitter cold. WNW-NW winds 5-15 mph, with higher gusts along mid-upper elevation mountain ridges. Temperatures in the single digits above and below zero ( coldest at the highest elevations ). Wind chills 0 to -15 below zero along middle elevation ridges and plateaus below 2700 feet, with chill factors of -10 to -25 below zero on ridges above 2700 ft.
Two important systems are being watched for wintry potential this coming week. The weaker first system is currently timed to arrive Wednesday ( January 20 ).
A second, potentially Major Winter Storm system, is currently timed to impact the region during the period from Thursday into Saturday ( January 21-23 ).
A third system, in a series, of potential concern may develop during the January 25-27 period.
Stay tuned for updates.
