Areas affected...Portions of southeastern OH...northern
WV...southwestern PA...western MD...and far northern VA
Concerning...Severe Thunderstorm Watch 85...
Valid 080552Z - 080715Z
The severe weather threat for Severe Thunderstorm Watch 85
continues.
SUMMARY...A line of strong to severe storms capable of producing
mainly damaging winds will continue east-southeastward. Downstream
watch issuance is possible.
DISCUSSION...Storms have grown upscale across parts of southeastern
OH into western PA, with mainly severe/damaging winds being
reported, including a gust to 75 mph at the Pittsburgh International
Airport. The airmass downstream of this ongoing convection is not
particularly unstable given cooler low-level temperatures and less
low-level moisture. With MUCAPE generally 500-1000 J/kg, storms may
have a tendency to become slightly elevated with time, particularly
with eastward extent. Still, given the well-organized nature of the
line and strong outbound velocities noted on KPBZ radar, there
appears to be a continued strong to damaging wind threat that may
extend to the south/southeast of ongoing Severe Thunderstorm Watch
85. Accordingly, another watch may be needed across parts of
southwestern PA into western MD and the eastern WV Panhandle.
