   AREAS AFFECTED...WRN AND CNTRL NC/NRN SC
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 261804Z - 262000Z
   
   ISOLATED LARGE HAIL WILL BE POSSIBLE THROUGH THE REMAINDER OF THE
   AFTERNOON WITH THE STRONGEST STORMS. WW NOT ANTICIPATED ATTM.
   
   TSTMS CONTINUE TO DEVELOP ACROSS WRN NC INTO NRN SC THIS AFTERNOON
   BENEATH MID-LEVEL COLD POOL ASSOCIATED WITH SHORTWAVE TROUGH MOVING
   ACROSS THE AREA. RESIDUAL DEWPOINTS IN THE MID TO UPPER 50S AND
   RELATIVELY STEEP MID-LEVEL LAPSE RATES ARE CONTRIBUTING TO SBCAPES
   OF 1000-1500 J/KG. DUE TO THE CLOSE PROXIMITY OF THE MID-LEVEL
   TROUGH AXIS...DEEP-LAYER SHEAR REMAINS RATHER WEAK ACROSS AREA.
   THEREFORE...THE MAJORITY OF ACTIVITY IS EXPECTED TO REMAIN
   DISORGANIZED. HOWEVER...GIVEN THE DEGREE OF INSTABILITY AND
   CONVERGENCE INVOF SURFACE LOW...ISOLATED STRONG STORMS ARE POSSIBLE
   WITH THE POTENTIAL FOR LARGE HAIL.
   
   DUE TO THE EXPECTED LIMITED COVERAGE...A WW IS NOT ANTICIPATED AT
   THIS TIME.
