Areas affected...northwest MO...southern IL...far southern
IN...northern and central KY

Concerning...Severe Thunderstorm Watch 331...332...

Valid 060044Z - 060215Z

The severe weather threat for Severe Thunderstorm Watch 331, 332
continues.

SUMMARY...A gradual weakening trend is expected with ongoing storms
across WW 331 and WW 332. A few strong to severe gusts remain
possible in the short-term, but additional watch issuance is not
expected.

DISCUSSION...A band of convection from northwest MO into southern IL
has generally shown a gradual weakening trend over the last hour.
The strongest measured wind gusts recently have been near St. Louis,
where 40 kt was observed. Another band of storms was arcing across
southern IN into north-central KY this evening and also was
producing sub-severe gusts. Storms will continue to shift southward
this evening, and more southeasterly across KY and continue to
gradually weaken as boundary layer CINH increases with loss of
daytime heating. A few strong gusts could persist outside of WW 331
across MO, but with the overall threat diminishing, a new
watch/aerial extension of the current watch are not expected.
Stronger convection may tend to persist a bit longer across eastern
portions of WW 332 where deep layer flow is stronger than further
west, but the threat should remain contained by the current bounds
of WW 332 or move into WW 334.
