   AREAS AFFECTED...SRN AR...NRN LA
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 300330Z - 300430Z
   
   AN ISOLATED TORNADO THREAT AND/OR WIND DAMAGE THREAT WILL BE
   POSSIBLE WITH CELL ELEMENTS EMBEDDED IN THE LINE OF THUNDERSTORMS
   ACROSS SRN AR AND NRN LA. THE THREAT IS EXPECTED TO REMAIN TOO
   MARGINAL TO WARRANT WW ISSUANCE.
   
   A LINE OF THUNDERSTORMS ONGOING FROM EAST OF LITTLE ROCK SSWWD TO
   EAST OF SHREVEPORT IS LOCATED ABOUT 40 TO 70 STATUTE MILES EAST OF A
   COLD FRONT AND IS ALIGNED VERY CLOSELY WITH THE AXIS OF THE
   LOW-LEVEL JET. REGIONAL WSR-88D VWPS NEAR THE LINE SUGGEST LOW-LEVEL
   SHEAR PROFILES ARE VERY STRONG WITH 0-1 KM SHEAR VALUES IN THE 40 TO
   50 KT RANGE. THE LOW-LEVEL SHEAR COMBINED WITH STRONG VERTICAL SHEAR
   THROUGH A DEEP LAYER MAY SUPPORT BRIEF ROTATING CELL ELEMENTS
   EMBEDDED IN THE LINE. ALTHOUGH THE SEVERE THREAT SHOULD REMAIN VERY
   ISOLATED...ROTATING CELLS MAY HAVE POTENTIAL FOR A BRIEF TORNADO. A
   FEW DAMAGING WIND GUSTS WILL ALSO BE POSSIBLE ESPECIALLY WITH
   SHORT-BOWING LINE-SEGMENTS.
