THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 132
CONTINUES.

SUMMARY...A THREAT FOR LARGE HAIL AND DAMAGING GUSTS WILL CONTINUE
FOR THE NEXT 1-2 HOURS BEFORE DIMINISHING.  AN ADDITIONAL SEVERE
THUNDERSTORM WATCH WILL NOT BE NEEDED BUT PERHAPS EXTENSIONS-IN-TIME
MAY BE NEEDED IN LOCALIZED AREAS FOR AN ADDITIONAL HOUR.

NERN MO/W-CNTRL IL SWWD INTO N-CNTRL AR.  STEEP H7-H5 LAPSE RATES
LOCATED OVER THE AREA /8 DEG PER KM AT SGF/ PER 00Z RAOB DATA AND
ADEQUATE DEEP-LAYER SHEAR SUPPORTIVE OF MULTICELLS AND SUPERCELLS
WILL FAVOR A CONTINUED RISK FOR LARGE HAIL/LOCALLY DAMAGING GUSTS
FOR THE NEXT 1-2 HOURS.  AFTER 02Z /SEVERE THUNDERSTORM WATCH 132
EXPIRATION TIME/...DIURNAL COOLING EXPECTED TO OCCUR BETWEEN NOW AND
02Z WILL ACT TO LESSEN BUOYANCY AND RESULT IN A GRADUAL DIMINISHING
OF STORM INTENSITY THIS EVENING.  HOWEVER...A FEW STRONGER STORMS
MAY CONTINUE TO POSE AN ISOLD SEVERE THREAT NEAR OR AFTER 02Z AND A
LOCAL EXTENSION-IN-TIME AND/OR EXTENSION-IN-AREA WILL BEST HANDLE
THIS SCENARIO.
