   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 276
   CONTINUES.
   
   LINE OF STORMS OVER CENTRAL OH CONTINUES TO TRACK EASTWARD AND
   APPEARS TO HAVE WEAKENED SOMEWHAT.  ISOLATED SEVERE THREAT MAY
   PERSIST EASTWARD FOR ANOTHER HOUR OR SO.  HOWEVER...PRESENT
   INDICATIONS ARE THAT ADDITIONAL WATCHES MAY NOT BE NECESSARY.
   
   N-S LINE OF THUNDERSTORMS JUST EAST OF CMH CONTINUES TO MOVE
   EASTWARD AT OVER 40 KNOTS.  IR CLOUD TOP TEMPERATURES AND RADAR
   SIGNATURES SUGGEST THESE STORMS HAVE WEAKENED SOMEWHAT IN THE LAST
   30 MINUTES.  FURTHER WEAKENING IS EXPECTED AS STORMS MOVE EASTWARD
   INTO AN INCREASINGLY MORE STABLE AIR MASS.  LOCALLY GUSTY/DAMAGING
   WINDS ARE STILL POSSIBLE FOR ANOTHER HOUR OR SO.  HOWEVER...OVERALL
   THREAT APPEARS TO HAVE LESSENED.  NEVERTHELESS...THIS REGION WILL BE
   CLOSELY MONITORED FOR RE-INTENSIFICATION.
