Areas affected...Southeast MO...Southern IL

Concerning...Severe Thunderstorm Watch 222...

Valid 132309Z - 140115Z

The severe weather threat for Severe Thunderstorm Watch 222
continues.

SUMMARY...Gusty winds remain possible with convection this evening.
However, new watch is not currently anticipated.

DISCUSSION...Weak low-level warm advection persists across the
Midwest into the lower OH Valley early this evening, coincident with
a surface front draped from central IN-central IL-central IA.
Scattered convection persists along this corridor but updraft
intensity has waned over the last few hours amidst neutral/weak
height rises aloft. While modest instability resides immediately
downstream across southern MO into southern IN, convective trends do
not favor organized severe persisting beyond watch expiration time.
