Areas affected...West Virginia...eastern Virginia...and southern
Pennsylvania
Concerning...Severe potential...Watch possible=20
Valid 231937Z - 232130Z
Probability of Watch Issuance...60 percent
SUMMARY...The potential for damaging wind continues across West
Virginia into southern Pennsylvania and eastern Virginia. A watch is
possible if current trends continue.
DISCUSSION...A loosely organized squall line continues to shift
eastward towards the Appalachians with several wind damaging
reports, including a couple of severe wind gusts, noted over the
past hour. IR and lightning trends have intensified over the past
hour as the line encounters a more unstable air mass. A similar
thermodynamic environment is noted downstream into the Appalachians,
which suggests that the potential for damaging winds may continue
for the next couple of hours despite meager deep-layer shear
overall. Trends will continue to be monitored, and watch issuance is
possible for parts of the Appalachians if ongoing convection
continues to support damaging wind gusts.
