Mesoscale Precipitation Discussion 0378
NWS Weather Prediction Center College Park MD
952 AM EDT Wed Jun 10 2026

Areas affected...Southeastern Ohio Valley into portions of the
Central Appalachians

Concerning...Heavy rainfall...Flash flooding possible

Valid 101351Z - 101851Z

SUMMARY...Complex of thunderstorms will continue to push through
Southern West Virginia into southwest Virginia leading to
potential for flash flooding next several hours.

DISCUSSION...Organized area of convection from a mature complex of
thunderstorms continues to maneuver through the southern third of
WV this morning. Complex will continue to work east-southeastward
with a trailing band of heavy rainfall materializing along an
outflow boundary brought about by the current complex. Recent CAMs
have the next 2-4 hours as the main period for additional heavy
rain prospects before encountering a less favorable environment
with dry air likely to occur via down-sloping off the Central
Appalachians. MU CAPE between 750-1500 J/kg has allow for
sufficient buoyancy for the complex to maintain prevalence, so
expectations are for the thunderstorms to sustain character and
produce locally heavy amounts of rainfall.

Flash flood warnings are already in effect for parts of
southwestern WV, and the expectation is for a few more to
potentially be added as the complex encounters steep terrain and
areas that have a history of complex drainage and local flash
flood concerns. Additional rainfall totals between 1-3" are
expected within the path of the complex as it moves through the
area, exceeding the 3-hr FFG threshold in place over the area.
Flash flooding will be possible over the next several hours as a
result.
