Areas affected...portions of eastern OH into western WV and western
PA

Concerning...Severe potential...Severe Thunderstorm Watch likely=20

Valid 182348Z - 190045Z

Probability of Watch Issuance...80 percent

SUMMARY...A mature squall line continues to advance eastward with
severe gust potential. This line is expected to advance east of
ongoing Severe Thunderstorm Watches 436-437, necessitating a
downstream Severe Thunderstorm Watch issuance.

DISCUSSION...A mature QLCS continues to propagate eastward, with
recent reports of measured gusts in the 50-68 mph range in the past
hour or so. This line will continue advancing eastward into a
moderately unstable airmass, which will support additional strong to potentially severe gusts. As such, a downstream Severe Thunderstorm
Watch will be needed soon.
