Mesoscale Discussion 1975
NWS Storm Prediction Center Norman OK
1246 PM CDT Sat Sep 14 2019
Areas affected...Parts of eastern West Virginia...far western
Virginia...Maryland Panhandle
Concerning...Severe potential...Watch unlikely
Valid 141746Z - 141945Z
Probability of Watch Issuance...5 percent
SUMMARY...Scattered thunderstorm development is expected in the next
few hours. Damaging gusts may accompany the stronger storms. A WW
issuance is not anticipated.
DISCUSSION...Owing to recent diurnal heating, towering cumulus have
recently become established across parts of the central Appalachians
ahead of an approaching cold front. Continued heating within breaks
of the low-level stratus will likely result in modest buoyancy, with
MLCAPE exceeding 1000 J/kg in several locales. While more
appreciable flow aloft will glance the region to the north, modest
low and mid-level flow will likely contribute to marginal deep-layer
and low-level speed shear to promote some organization with the more
intense updrafts over the next few hours. In turn, the more
sustained storms may produce a few damaging gusts, particularly in
areas of higher terrain. Nonetheless, severe gusts are expected to
be rather sparse in nature, precluding a WW issuance.
