Areas affected...Upper Ohio Valley Vicinity

Concerning...Severe potential...Watch unlikely

Valid 142152Z - 142315Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated damaging winds and perhaps a brief tornado are
possible into the next couple of hours in southwest Pennsylvania. A
watch is not expected.

DISCUSSION...A weak MCV continues to promote thunderstorm
development in southwest Pennsylvania into northern West Virginia.
The environment farther east is drier and should lead to a general
downtrend in intensity with time. That being said, storms closely
tied to the MCV could produce isolated damaging gusts. The low-level
wind shear near the MCV core is slightly enhanced per the KPBZ VAD.
A brief tornado, though unlikely, is possible in southwest
Pennsylvania immediately ahead of the MCV.
