Areas affected...southeast MO vicinity into western and Middle TN
and western into central KY

Concerning...Severe Thunderstorm Watch 430...431...

Valid 021942Z - 022145Z

The severe weather threat for Severe Thunderstorm Watch 430, 431
continues.

SUMMARY...Thunderstorm activity is expected to increase over the
next couple of hours across parts of western/central Kentucky into
western and Middle Tennessee. Damaging wind risk continues across WW
430 and 431.

DISCUSSION...Isolated thunderstorms are developing between two main
clusters of storms (one along the Ohio River to the MO/AR border to
the north, and the other across MS/AL to the south). In addition to
new development, ongoing thunderstorm clusters are expected to move
into parts of western/south-central KY and western/Middle TN with
time. Moderate instability and favorable shear amid a very moist
airmass will continue to support strong/damaging wind potential the
remainder of the afternoon into early evening.

Deepening cumulus are evident over eastern portions of the
Louisville forecast area (east-central KY). Depending on convective
trends across this area, a downstream watch may be needed across
parts of eastern KY by around 21-22z.
