When winter arrives the High Knob Massif can
be simply wicked, but there is no denying the awesome majesty that also comes with this
season of snow, ice, water, and wind!

Getting to the heart of this barbaric air mass was rather dramatic with evening rain January 5 giving way to ROARING gusts of tree limb breaking wind just after Midnight, into January 6, as the first cold front reached the mountains.
Wind gusts from around 30 mph to 50+ mph were reported
across the region as this initial cold front pushed into the
western Appalachians.
Rain turned to snow around 12:28 AM January 6 on Eagle Knob of the High Knob Massif with a rapid drop in snow levels down to Clintwood 1 W
by 1:40 AM ( a vertical drop of 2629 feet in the snow level in just over 1 hour ).
Much like during the first arctic blast, of January 2-3, a period of system snow gave way to a brief lull in activity in advance of the Arctic Front and heavier upslope snowfall.

While highest elevations were coldest during the advection periods of the arctic blasts ( when cold air was being transported into the mountains ), coldest mean conditions have been in mid-upper elevation mountain valleys and places with northern exposures and snow cover.
The City of Norton Water Plant exemplified this with a Mean Daily MAX during January 1-9 of 28.8 degrees [ when calculating the MEAN temperature through the first 12 days of January there is only a 0.6 degree Fahrenheit difference between Norton WP & Norton AWS, with Norton WP cooler by day and Norton AWS cooler by night ( as has always been observed in the mean )].

Although portions of the Great Valley did get 0.5" to 1" of snow during this event, it was again short-lived in the Tri-Cities with another large contrast between windward and leeward locations
across the mountains.

While highest elevations were coldest during the advection periods of the arctic blasts ( when cold air was being transported into the mountains ), coldest mean conditions have been in mid-upper elevation mountain valleys and places with northern exposures and snow cover.
The City of Norton Water Plant exemplified this with a Mean Daily MAX during January 1-9 of 28.8 degrees [ when calculating the MEAN temperature through the first 12 days of January there is only a 0.6 degree Fahrenheit difference between Norton WP & Norton AWS, with Norton WP cooler by day and Norton AWS cooler by night ( as has always been observed in the mean )].
