[html]MD 1704 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF EASTERN OHIO INTO THENORTHERN WEST VIRGINIA PANHANDLE AND WESTERN PENNSYLVANIA
Mesoscale Discussion 1704
NWS Storm Prediction Center Norman OK
0449 PM CDT Sat Aug 20 2022
Areas affected...portions of eastern Ohio into thenorthern West
Virginia Panhandle and western Pennsylvania
Concerning...Severe potential...Watch unlikely
Valid 202149Z - 202315Z
Probability of Watch Issuance...20 percent
SUMMARY...A couple instances of damaging gusts or large hail are
possible this evening. A WW issuance is not expected since the
severe wind/hail threat is expected to be isolated.
DISCUSSION...MRMS mosaic radar imagery depicts mature multicellular
clusters in progress across OH, which are currently benefiting from
2000 J/kg MLCAPE. However, RAP forecast soundings suggest that the
vertical CAPE profiles are tall and skinny, driven primarily by the
upper 60s F dewpoints. In addition, tropospheric winds/shear remain
weak across the warm sector, and low-level moisture/buoyancy
decrease with eastern extent into western Pennsylvania. As such, an
isolated severe threat is expected to persist for a few more hours,
and should gradually beco*e even more sparse through the evening. A
WW issuance is not expected.
