Areas affected...portions of far northern Ohio into extreme
northwestern Pennsylvania and extreme southwestern New York

Concerning...Severe Thunderstorm Watch 659...

Valid 280039Z - 280215Z

The severe weather threat for Severe Thunderstorm Watch 659
continues.

SUMMARY...Some severe threat will persist for a few more hours in
and immediately surrounding Severe Thunderstorm Watch 659. Damaging
gusts remain the primary concern.

DISCUSSION...A pronounced cold pool, originating from a mature
persistent elongated convective system, has surged southeastward
across Lake Erie over the past couple of hours. At least a few
severe gusts have been observed, and some convective rejuvenation
has occurred along the cold pool leading edge. Buoyancy
decreases/MLCINH increases with eastward and southward extent ahead
of the ongoing storms/cold pool. However, the fast pace of the cold
pool suggests that continued cellular regeneration and acco*panying
damaging wind gust potential will continue for at least a couple
more hours.
