West Virginia...far southwestern Pennsylvania

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

Valid 281814Z - 281945Z

Probability of Watch Issuance...5 percent

SUMMARY...A couple of strong/damaging wind gusts may occur with the
stronger storms this afternoon. A WW issuance is unlikely given the
sparse nature of the overall severe threat.

DISCUSSION...Scattered thunderstorms have developed ahead of a weak
frontal boundary, amid a modifying airmass behind an earlier MCS.
Here, surface temperatures are rising into the upper 80s F, that
combined with low 70s F dewpoints and 8 C/km 0-3 km lapse rates, are
boosting MLCAPE to 2500 J/kg. However, modest deep-layer westerly
flow is resulting in weak vertical wind shear, and with buoyancy
constrained to tall/narrow profiles, the main concern is for
damaging gusts originating from the stronger storm cores. The severe
threat should remain quite isolated, so a WW issuance is not
expected.
