THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 459
CONTINUES.

459 WILL BE ALLOWED TO EXPIRE DUE TO ANTICIPATED WEAKENING OF
STORMS. IN THE MEANTIME A MODEST THREAT FOR MAINLY ISOLATED DAMAGING
WIND WILL PERSIST FROM NRN MO INTO SERN IA.

MO. MOST OF THE STORMS ARE DEVELOPING ON COOL SIDE OF ASSOCIATED
CONVECTIVE OUTFLOW BOUNDARY. IN ADDITION...THE BOWING SEGMENT WITH
COMMA HEAD OVER SE IA HAS FINALLY BEGUN TO WEAKEN. THESE TRENDS ARE
INDICATIVE OF INCREASING CONVECTIVE INHIBITION...WHICH IN ADDITION
TO LIMITED FORCING ASSOCIATED WITH ONLY A WEAK WSWLY LLJ SUGGEST AN
