Mesoscale Discussion 1792
NWS Storm Prediction Center Norman OK
0801 PM CDT Thu Aug 01 2024

Areas affected...Eastern KY/TN into western VA and extreme southwest
WV

Concerning...Severe Thunderstorm Watch 589...

Valid 020101Z - 020230Z

The severe weather threat for Severe Thunderstorm Watch 589
continues.

SUMMARY...Some threat for damaging wind will continue eastward
through the evening.

DISCUSSION...While the northern portion of the long-lived MCS moving
across KY has weakened, some intensification has been noted along
the southern portion of the gust front, as the attendant cold pool
has overtaken a preceding band of convection that developed from
northeast TN into southeast KY. This portion of the MCS produced a
49 kt gust near London, KY, and will pose the greatest relative
threat for damaging wind. A gradual weakening trend is expected
later tonight, as MLCINH begins to increase and downstream buoyancy
decreases, but in the short term, warm/moist conditions and MLCAPE
of greater than 1500 J/kg will support at least isolated
damaging-wind potential through much of the evening.
