Mesoscale Discussion 1156
NWS Storm Prediction Center Norman OK
0431 PM CDT Fri Jun 06 2025

Areas affected...portions of eastern West Virginia to southeast
Virginia

Concerning...Severe potential...Watch unlikely=20

Valid 062131Z - 062300Z

Probability of Watch Issuance...20 percent

SUMMARY...An isolated severe threat will persist across southern
portions of the Mid-Atlantic through the remainder of the afternoon.
Strong wind gusts are the main threat, though an instance of large
hail could occur.

DISCUSSION...Multiple multicellular storm clusters have developed in
a nebulously forced regime, and have been driven primarily by strong
surface heating/mixing of the boundary layer, as well as orographic
lift. Given robust boundary layer mixing, 7-8 C/km 0-3 km lapse
rates are boosting MLCAPE to 1500 J/kg in spots. With up to 35 kts
of effective bulk shear in place, the aforementioned buoyancy is
promoting occasionally organized, strong storms with a history of
damaging gusts. Strong wind gust potential should continue through
the remainder of the afternoon, until nocturnal cooling dampens the
steep low-level lapse rates in place. Given organized multicellular
modes, an instance or two of hail also cannot be ruled out. However,
the overall severe threat should remain isolated.
