The famed 30-day period of most explosive spring renewal has now arrived, with a blanket of snow! 

*The April 15 to May 15 period is climatologically the interval which generates the most dramatic landscape changes as winter gives way
to spring rebirth.  Only upper elevations, above 3000 feet, within the High Knob Massif require longer ( often to early June ) to complete
the transition to full summer conditions.

A huge temperature plunge during April 16 brought snow, strong winds and bitterly cold wind chills to the high country, with several inches accumulating at highest elevations in the High Knob Massif.

Maple trees are beginning to bud in the high country as a few spring ephemeral wildflowers emerge upon the open forest floor during what 
has been a chilly April in 2018.

Chilly April In High Country

The first 21 days of April featured numerous spells with temperatures dropping into the 10s to lower 20s within the high country of the High Knob Massif.  This included up to 9.0 inches of total snowfall at highest elevations.

Canada Mayflowers ( Maianthemum canadense ) were emerging across many acres on April 21; however, not a single flower was yet found to be blooming.  Dwarf Anemone and Halberd-leaved Violets are the most numerous species blooming above 3000 feet ( as of April 21 ).

*It is still early for Canada Mayflower to be blooming, 
with May typically being the month to feature blooms 
on this northern species.

A snow core generated 0.68" of water content to suggest at least 7" fell, if not a bit more given that snow density in these upper elevations had a snow-to-water ratio somewhat greater than 10:1 . 

*Most of the snow fell with air temperatures in the 10s to low-mid 20s.

Only part of the March 20-22 storm was snow, with a total water equivalent of around 2.00" or more in these upper elevations ( 1.28" measured at the base in the City of Norton ).

This continued a very wet pattern that had the 2018 precip tally up to approximately 25.00" at 
Big Cherry Lake Dam in advance of the nasty, water loaded snow-ice storm of March 24-25.

Another morning featuring 10s in high country valleys is upcoming into April 5.


Historic Snowstorm
April 2-5, 1987

Spring snow is common in the mountains, with historic events occasionally occurring as mT 
( maritime tropical ) and cP ( continental Polar ) 
air masses clash.

A historic late season winter storm generated a general 2 to 4 feet of snow depth in locations along and north of the High Knob Massif during the first days of April in 1987.

Carl Henderson, electrical engineer for the former Blue Ridge PBS transmitter station on Eagle Knob of the High Knob Massif, reported a general 2 to 6 feet of snow depth in wake of this major event.

Total snowfall was generally significantly more than total snow depths due to settlement, melting and sublimation amid higher spring solar angles than indicated below ( the exception being much higher drifts which locally formed along mountain ridges ).

Nearly 2000 vertical feet below, Gary Hampton reported 3 feet of snow depth at the City of Norton Water Plant on the northern base of the High Knob Massif.  These were the greatest depths reported in Virginia during this event.

U.S.G.S. Digital Elevation Model

Great storm events tend to accentuate the great orographic sections of the Appalachians, with this epic April 1987 snowstorm being no exception.

Snow Depth Differentials

*High Knob Massif-Kingsport
48" - 11" = 36"

**Pickens-Millgap
42" - 10" = 32"

*A total of 14.8" officially measured at TRI in northeastern Tennessee which, like Kingsport, was downstream of the High Knob Massif & Cumberland Front during much of 
this storm event.

**Difference between Pickens, Wv., and Millgap in Highland County, Va., which was downstream of the Allegheny Front during much of this event.  A total of 32.8" of snow was measured at Snowshoe Mountain.

Bigger events in the past have generated even larger differences along storm flow trajectories, of course, with this being a nice mid-spring example.


Slow Emergence In 2018

The first Rue Anemones began blooming in lower elevations of South Fork Gorge of the Powell River by the end of February-early March, in wake of record February wetness and unseasonable mildness during mid-late month.  Numerous snowy periods and cold followed in March.

A colder, more snowy March than February in 2018 has emergence of spring ephemeral wildflowers off to a slow start, at least within locations along and north of the High Knob Massif.

Some signs of spring are finally beginning to emerge in the high country, with Halberd-leaved Yellow Violets ( Viola hastata ) in bloom along with the first Dwarf Anemones ( Anemone quinquefolia var. minima ).  A vast array of Canada Mayflower 
( Maianthemum canadense ) is coming up but not yet blooming.

A total of 12.86" was hand-measured by superintendent Gary Hampton and his staff at 
the Big Stone Gap Water Plant, near the mouth 
of South Fork Gorge, during February to top the previous valley record established by the Big Stone Gap Wastewater Treatment Plant in 2003.

*The 11.81" measured by the Big Stone Gap WWTP during 2003 established a new record for February wetness in the state of Virginia ( a general 12.00" to 13.00" fell in the high country of the High Knob Massif in February 2003.

*Although snow core data was used to help make this total more accurate, it likely remains too low given significant wind induced rain gauge undercatches as air flows across 
the highly elevated Dam.

A huge contrast in precipitation amounts has been observed across southwestern Virginia, and the Old Dominion, during this winter season.



Amazingly, a large portion of Virginia is currently experiencing abnormally dry to drought conditions.

Observe that totals decrease both UP-basin along the Clinch River and eastward across southwestern Virginia.  A trend that shows up well in longer-term climatology during the orographic forcing season.

The Orographic Forcing Season is November-April, with May and October often being months of transitions between the Orographic and Convective seasons.

Spring 2018 Flood Outlook

Richlands recorded the most February precip in locations upstream of the High Knob Massif, within the Blacksburg NWS Forecast Office coverage area of the Clinch River Basin, with 7.63" .

A total of 8.48" was measured in the Town of Lebanon, but it is 
within the Morristown, Tn., NWS Forecast Office coverage area.

Although only a fraction of their original size, drifts remained notable along wind swept crest lines a couple 
days after this latest winter storm event ( one of a series 
of wintry systems to impact the high country in March ).

Large snow drifts lingered along high crest lines around High Knob in wake of the winter storm event of March 12-14, which dropped a foot or more of snow in the high country.
