   VALID 180639Z - 180845Z
   
   AN ISOLATED TORNADO THREAT WILL EXIST IN THE COASTAL PLAINS OF THE

   ACROSS MD...DE AND NJ. WITHIN THE BANDS...SOME CELLULAR ACTIVITY IS
   PRESENT AND THESE STORMS WILL HAVE POTENTIAL TO ROTATE AS THEY MOVE
   NWD ACROSS THE REGION. FORECAST SOUNDINGS SHOW LOOPED HODOGRAPHS
   WITH MODERATE LOW-LEVEL VEERING. IN ADDITION SFC DEWPOINTS IN THE

   LOW LCLS AND STRONG DIRECTIONAL SHEAR ALONG AND SOUTHEAST OF A
   QUASI-STATIONARY BOUNDARY OVER FAR ERN PA WILL BE FAVORABLE FOR
   MINI-SUPERCELLS. AN ISOLATED TORNADO THREAT WILL ACCOMPANY ANY
   ROTATING STORMS OVER THE NEXT FEW HOURS. HOWEVER...THE THREAT SHOULD
   REMAIN VERY ISOLATED AND SHOULD DIMINISH SOME AS INSTABILITY
   DECREASES ACROSS THE REGION THROUGH DAYBREAK.
