   CONCERNING...SEVERE THUNDERSTORM WATCH 59...
   
   VALID 240226Z - 240330Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 59
   CONTINUES.
   
   MUCH OF SEVERE THUNDERSTORM WATCH 59 HAS BEEN WORKED OVER BY EARLIER
   CONVECTION...BUT A FEW STRONGER CELLS HAVE MOVED INTO THE SRN PART
   OF THE WATCH FROM THE WEST...WHILE STORM INTENSITY HAS BEEN
   INCREASING SOMEWHAT ALONG AN OUTFLOW BOUNDARY MOVING INTO THE NERN
   PART OF THE WATCH. WHILE BUOYANCY IS WEAK ACROSS THE AREA... WITH MU
   CAPE 250-750 J/KG ACCORDING TO 01Z OBJECTIVE ANALYSIS...EFFECTIVE
   SHEAR AOA 40 KTS MAY SUPPORT SOME STORM ORGANIZATION FOR THE NEXT
   2-3 HRS...WITH AN ATTENDANT THREAT OF MARGINALLY SEVERE HAIL AND
   WIND. HOWEVER...INCREASING SFC-BASED CIN SHOULD DIMINISH THE WIND
   THREAT WITH TIME...WHILE WEAKENING MID-LEVEL LAPSE RATES WITH ERN
   EXTENT SHOULD LIMIT THE HAIL THREAT.
