...Straight-Line Wind Damage Confirmed in Hampshire County WV and
Frederick County VA From a Thunderstorm on Sunday April 30...

The National Weather Service Baltimore/Washington Forecast Office
conducted a storm survey to assess damage from a thunderstorm
that occurred from 4:30pm to 4:45pm on Sunday April 30 across the
border of Hampshire County WV and Frederick County VA. The survey
covered a triangle roughly bounded by Capon Bridge, WV, High View,
WV, and Gore, VA. About two dozen trees were observed down across
this area. This damage was then compared to doppler radar data
from NWS Sterling and FAA Dulles. It has been determined that the
trees fell from straight-line winds rather than tornadic winds.

Large hardwood and softwood trees were sporadically downed in the
Capon Bridge, WV area, including north along Cold Stream Rd, in
town along Hwy 50, and south of town on Christian Church Rd. The
trees south of Capon Bridge generally fell west to east as the
rear flank downdraft of the thunderstorm moved through as
identified by radar from 4:30pm to 4:35pm. The trees in Capon
Bridge and north generally fell northwest to southeast as the
forward flank of the thunderstorm moved through according to both
radars from 4:34pm to 4:40pm.

A separate area of multiple trees downed was identified between
Gore, VA and the VA/WV border. According to radar these fell from
4:35pm to 4:40pm. Several hardwood and softwood trees were downed
along a quarter mile stretch near the intersection of Hollow Rd and
Parishville Rd. These trees generally fell southwest to northeast as
the rear flank downdraft moved through the area. A few hardwood
trees were found downed south of Hollow Rd across a large orchard to
Carpers Pike. These trees fell in a divergent pattern and were on
the south end of the rear flank downdraft according to both radars.

Finally, two trees (one on either side of Highway 50 at Gore)
were downed. These trees fell roughly northwest to southeast as
the rear flank downdraft occluded as indicated by both radars
around 4:44pm.
