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.

Snow was heavy enough to make roads slick down to below the 3000 foot level by the early evening hours of April 16.

Although State Route 619 was already snow covered at highest elevations prior to 5:00 PM on April 16, the sticking snow level really dropped with heavy snow showers and squalls that developed prior to sunset ( with low visibility at times ).

A short video from the Computer Science-Mathematics building at UVA-Wise highlights these late afternoon-early evening snow showers and squalls; although, most of the daylight hours featured these conditions ( especially at upper elevations in the High Knob Massif which is 
rarely visible from Wise ).

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 have 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 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.
