NWS STORM PREDICTION CENTER NORMAN OK
0159 AM CDT WED MAR 11 2026
AREAS AFFECTED...PORTIONS OF CENTRAL ILLINOIS
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 110659Z - 110830Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...NUMEROUS THUNDERSTORMS MAY REMAIN CAPABLE OF ISOLATED
SEVERE GUSTS OR MARGINALLY SEVERE HAIL FOR A COUPLE MORE HOURS. A
NEW WW IS UNLIKELY.
DISCUSSION...SCATTERED TO NUMEROUS THUNDERSTORMS REMAIN ONGOING
ACROSS PORTIONS OF CENTRAL IL AS OF 0655 UTC. SEVERAL MULTICELLS
WITHIN AN EAST-WEST ORIENTED CLUSTER HAVE SHOWN OCCASIONAL STRONGER
UPDRAFTS AND REFLECTIVELY CORES OVER THE LAST HOUR. THIS COULD
CONTINUE FOR A FEW MORE HOURS THIS EVENING AS THE ENVIRONMENT
REMAINS GENERALLY UNSTABLE AND MODERATELY SHEARED, FAVORING SOME
ORGANIZED STORM POTENTIAL. ADDITIONAL LOOSELY ORGANIZED LINEAR
STORMS ARE APPROACHING FROM WESTERN MO. THIS COULD SUPPORT ISOLATED
SEVERE GUSTS AND PERHAPS MARGINALLY SEVERE HAIL FOR A COUPLE HOURS
ACROSS CENTRAL IL. HOWEVER, INCREASING NOCTURNAL INHIBITION AND
GENERAL ORGANIZATION TRENDS SUGGEST A SLOW WEAKENING IS LIKELY.
THUS, WHILE ISOLATED SEVERE REMAINS POSSIBLE, A NEW WW IS NOT
EXPECTED.
