...Summary...
The National Weather Service in Charleston WV has confirmed a
Microburst 2 miles SSW of Birch River in Nicholas County
West Virginia on 6/23/2016.

A storm moved across the state of West Virginia during the pre-
dawn hours of Thursday June 23rd. It moved through the Birch River
area just before 6 am causing a localized, but significant, patch
of damage. A National Weather Service survey team found the damage
consistent with 80 to 100 mph winds. Many trees were snapped and
uprooted. Four wooden electrical transmission line poles were
snapped. A single family residence received roof damage consisting
of shingle removal and tree debris impaled into the roofing deck.
Several small yard items were also blown, including a dog kennel
which struck the resident`s car and a kayak blown to another
property 500 ft away. All damage and debris was scattered toward
the NNW and exhibited a slightly divergent pattern consistent with
a microburst.

For reference...
A microburst is a convective downdraft with an affected outflow
area of less than 2 1/2 miles wide and peak winds lasting less
than 5 minutes. Microbursts may induce dangerous horizontal and
vertical wind shears...which can adversely affect aircraft
performance and cause property damage. Straight-line winds are
generally any wind that is not associated with rotation...used
mainly to differentiate them from tornadic winds.
