   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 309 CONTINUES.
   
   SEVERE/ISOLATED TORNADO THREAT CONTINUES ACROSS CENTRAL AND ERN
   INDIANA AND INTO WRN OH -- ACROSS VALID PORTIONS OF WW 309.
   
   LATEST RADAR LOOP SHOWS A BAND OF STRONG/LOCALLY-SEVERE STORMS
   MOVING ACROSS CENTRAL INDIANA ATTM.  STORMS HAVE SHOWN SOME DECREASE
   IN INTENSITY OVER THE PAST COUPLE OF HOURS -- LIKELY IN RESPONSE TO
   A SLOW DIURNAL STABILIZATION OF THE PRE-CONVECTIVE ENVIRONMENT. 
   HOWEVER...WITH LATEST IND VWP REVEALING SHEAR SUFFICIENT FOR
   CONTINUED STORM ORGANIZATION...THREAT FOR LOCALLY GUSTY/DAMAGING
   WINDS AND/OR HAIL -- OR AN ISOLATED BRIEF TORNADO -- WILL
   CONTINUE...LIKELY FOR THE NEXT COUPLE OF HOURS.
