Areas affected...Upper Ohio Valley

Concerning...Severe Thunderstorm Watch 80...83...

Valid 010158Z - 010400Z

The severe weather threat for Severe Thunderstorm Watch 80, 83
continues.

SUMMARY...Locally damaging winds will accompany squall line this
evening.

DISCUSSION...Surface front is gradually advancing southeast across
the Great Lakes this evening as a midlevel short-wave trough shifts
across LE/northern OH. An elongated, complex MCS has evolved ahead
of this feature with several clusters propagating east-southeast
across western PA into northern OH. In both cases a weak MCV is
likely evident within the broader precip shield which is indicative
of the maturity of this convection. Latest radar data suggests
damaging winds may be noted along the leading edge of these
arc-shaped squall lines. Although buoyancy is gradually decreasing
across this region, at least for the next few hours robust
convection will likely continue.
