Mesoscale Discussion 1649
NWS Storm Prediction Center Norman OK
1158 AM CDT Thu Aug 04 2022

Areas affected...Parts of central/eastern OH...western PA...northern
WV Panhandle

Concerning...Severe potential...Watch unlikely 

Valid 041658Z - 041900Z

Probability of Watch Issuance...5 percent

SUMMARY...Thunderstorms capable of isolated damaging wind gusts are
possible this afternoon.

DISCUSSION...c*nvection is gradually increasing in coverage and
intensity early this afternoon, along and ahead of a weak surface
boundary draped from northern OH into northwest PA. With deep-layer
shear expected to remain weak, convection is expected to remain
relatively disorganized. However, as MLCAPE increases into the
1500-2000 J/kg range and low-level lapse rates steepen with time,
the strongest cells/clusters may be capable of producing isolated
damaging wind as they spread northeastward this afternoon. Watch
issuance is not expected at this time.
