Mesoscale Discussion 1935
NWS Storm Prediction Center Norman OK
0457 PM CDT Sat Aug 17 2024
Areas affected...Southeast KY and extreme western VA
Concerning...Severe potential...Watch possible
Valid 172157Z - 172330Z
Probability of Watch Issuance...40 percent
SUMMARY...Damaging-wind threat will persist across southeast
Kentucky and far western Virginia through 00-01z.
DISCUSSION...A band of thunderstorms is spreading southeastward
across eastern KY on an aggregate convective outflow, in association
with the southern extent of a midlevel shortwave trough. Surface
temperatures remain in the mid-upper 80s to the south of the ongoing
storms, where MLCAPE is near 2000 J/kg. The combination of the
moderate-strong buoyancy and lingering/steep low-level lapse rates,
along with 30-40 kt midlevel flow per regional VWPs, will support a
continued threat for occasional wind damage with embedded
downbursts. Gradual cooling of the boundary layer will result in a
slow decrease in the severe threat near and after sunset.
