Blackberry Winter - Chilly Spell In May 2014

Air temperatures were in the 30s, with wind chills in the 20s, atop the High Knob Massif at the time of this view of jagged clouds and faint sun beams illuminating mountain slopes adorned by light green of late spring in the high country.


Airplane pilot Harless Greear recorded an awesome flight video during the morning of this day when the high country was mostly clear, above a morning inversion layer that still had patches of fog trapped in Powell Valley, the Clinch River Valley, and just northwest of the massif.

Cruising To High Knob On May 16, 2014

The flight begins near Powell Valley Overlook, and U.S. Route 23 in Wise County, Va., and the Limestone Rock Quarry of Vulcan Materials Company ( visible at lower right at start of video ).

Harless climbs the ridge rising above the Head of Powell Valley, the same long ridge line visible from the High Knob Massif Webcam that plunges downward from the main crest zone.

The southeastern side of Powell Valley and ruggedly majestic slopes of Powell Mountain are visible to the right of Harless's ascent up this ridge, with fog patches beneath a lingering morning inversion layer extending outward from cliff laden mountain slopes ( the awesome belt of calcareous cliffs being mostly hidden by trees but identified by vertical plunges of the mountain ).

[ Observe both this belt of cliffs and steepness of this mountain flank ( SE limb of the Powell Valley Anticline ) are revealed by shadows that plunge nearly vertically downward from the Greenbrier Limestone Belt of jagged rocks ].

Rocky Hollow becomes visible 35-40 seconds into the flight, adjacent to great Grindstone Ridge with its 2000 vertical feet of plunge in only 0.8 air mile ( the front as viewed from Powell Valley having a distinct dome shape while the crest, as seen from this perspective has a rather even, upward sloping appearance ).

[ Rocky Hollow features a long boulder field and creek that
goes subterranean amid various places and conditions ].

Just beyond 1:00 minute into the flight video the sprawling nature of the mountain mass becomes increasingly apparent as the head of Rocky Hollow is approached with the main peak of High Knob visible at top left.  A forest clearing at 3800 feet above sea level is reached by 1:33 just above Rocky Hollow Gap, beyond which the airplane crosses the portion of Big Cherry Lake Basin that includes the High Knob peak.

The front edge of the mountain flank visible during 
this upward flight, from the head of Rocky Hollow and Grindstone Ridge southwest, marks the northwest rim 
of Big Cherry Lake Basin while the high crestline seen stretching from High Knob and Little Mountain Knob southwest marks the southeast rim of Big Cherry Basin 
( the upper basin plunging from Grindstone Ridge, High Knob, and Little Mountain Knob to lofty valley floors resting around 3200 feet above sea level ).

[ Observe how tree leaves remain immature and far from summer
maturity amid these upper elevations, with some trees still bare ].

Harless is over State Route 619 by 2:03 and it becomes possible to see through the gap between High Knob ( to the left ) and Little Mountain Knob ( in front ) into 
lofty High Knob Lake Basin.

[ Little Mountain Knob is the site of a new trail head for
the Chief Benge Hiking-Horseback Riding Trail System,
with 33 miles officially designated during Summer 2012 ].

The other side of the mountain top becomes visible by 2:10 as an upward bow shaped crestline at far left, with the loop on Little Mountain Knob subsequently crossed to reveal the massive size of this sprawling mountain 
( only a small part being visible here ). 

[ Large base-to-base and crestal widths are what separate
the High Knob Massif from most other mountains in the
Appalachians, making it topographically unique ].

A portion of Big Cherry Basin, with its lofty wetland valleys, is also visible across right side of view at 2:28 as the head of long, rugged Straight Fork Basin is in front of Harless as he begins a steep, leftward turn.

[ Big Cherry Lake Basin gives birth to South Fork of Powell River, part of the famed headwaters of the Upper Tennessee River Basin, and has the highest annual precipitation average ever observed in Virginia. This is truly a unique section of the Old Dominion ].

During the steep, left turn the other side of the top becomes clearly visible at 2:36 as the upward bowed or boomer-rang shaped crestline locally called Osborne Ridge, rising south-southeast of Bark Camp Lake.

Lofty High Knob Lake Basin is in center of view at 2:42 as the steep, leftward bank continues to bring the airplane back around to where the summit of Eagle Knob ( with visible towers ) comes into view by flight minute 2:48 .

[ The Eagle Knob Communications Area has a summit elevation of 4189 feet and is the second highest summit in the Cumberland Mountain range behind the High Knob peak at 4223 feet ].

Harless had the airplane aligned once again with 
the peaks of Little Mountain Knob, High Knob, and Grindstone Ridge by 2:58 and heads back across 
Little Mountain to High Knob Meadow by 3:32, site 
of the new High Knob Lookout Tower construction.

[ During this portion of the flight the head of Big Cherry Lake Basin was nicely framed by Grindstone Ridge, Little Mountain Knob, and High Knob ( i.e., the area now visible to left of view ) ].

Upon crossing the High Knob peak expansive northern slopes become visible by 3:36, with Benges Basin amid center of view hiding the dual Reservoirs 
of the City of Norton.

[ A separation in the trees reveals the course of State Route 619 as it crosses Chestnut Flats ( at 3800 feet ) to begin a long, downward descent into the City of Norton at 2141 feet ].

A traditional spell of Blackberry Winter, for which the Appalachians are famous, was felt during May 15-19 as unseasonably warm, summery conditions gave way to much needed rainfall and plunging temperatures!

An impressive change in weather conditions was associated with this plunge into Blackberry Winter via more than 50 degrees of air temperature drop between May 13 and May 17.

A brief preview of upcoming attractions was presented by Mother Nature on May 10 via a general 0.50" to 1.00" of rain and MAX temps in the 50s to middle 60s.  

Lingering moisture generated widespread dense fog, below 3000 feet elevation, into morning hours of May 11.

Observe how the high country of the High Knob Massif 
is ringed by dense fog, standing out as the clear section along the borders of Wise, Scott, and northeastern Lee counties in southwestern Virginia.

A wave of unseasonable heat sent temps soaring 
by May 13 when the climax of heat produced max readings of 75 degrees on High Knob, 83 degrees in the City of Norton, and 87 degrees in Clintwood to contrast with frosty cold nights ahead.

Colder mountain valleys, above 2500 feet, dropped into the upper 20s to around 30 degrees during morning hours of May 17-19.  Three consecutive mornings with frost were also observed in some lower valleys across Dickenson-Wise counties during this period.

May 16-17 featured the coolest days.

The Chill of Blackberry Winter
Breaks Interstate Park to High Knob Massif
May 17, 2014

A period of clearing allowed air temps to reach upper 20s to lower 30s in mid-upper elevation mountain valleys from the City of Norton across the High Knob Massif into early hours of May 17.

The High Knob Massif area was at the epi-center of this chilly May air mass as seen by overlaying air temperatures onto these NASA visible images.

Temperatures struggled to stay around 50 degrees in Norton-Wise and around 40 degrees atop the high country surrounding High Knob amid 
"peak" afternoon heating!

Although temps remained cool, with middle 50s 
to lower 60s atop the High Knob Massif for MAXS during May 18-19, more sunshine made the crisp air more tolerable by day prior to frosty coldness at night amid drainage into high mountain valleys.
