   ISOLATED SEVERE STORMS MAY OCCUR LATER THIS AFTERNOON OVER CNTRL AND
   ERN LA AS WELL AS CNTRL/SRN MS. A WATCH IS NOT EXPECTED TO BE
   NECESSARY AT THIS TIME.
   
   A LINE OF STORMS CONTINUES TO PUSH SLOWLY EWD ACROSS LA...ASSOCIATED
   WITH A WEAK COLD FRONT. THESE STORMS ARE NOT CURRENTLY SEVERE...BUT
   MAY EVOLVE OVER THE NEXT SEVERAL HOURS.
   
   SWLY LOW LEVEL FLOW WILL CONTINUE THROUGHOUT THE DAY...AS THE
   PRIMARY UPPER TROUGH AND SURFACE LOW MOVE NEWD ACROSS OK/AR/MO. AS
   THE LATEST SURFACE ANALYSIS SHOWS...RICHER LOW LEVEL MOISTURE IS
   GRADUALLY MOVING INLAND ACROSS LA AND SRN MS...WITH SOLID 64 TO 67 F
   DEWPOINTS NOTED AT 17Z. FURTHER...VISIBLE IMAGERY SHOWS CLEARING NOW
   TAKING PLACE...WITH TEMPERATURES RISING INTO THE MIDDLE 70S F.
   
   ALTHOUGH LAPSE RATE PROFILES FROM THE LOW TO MID LEVELS ARE
   RELATIVELY POOR...CONTINUED HEATING WILL YIELD SOME FURTHER
   DESTABILIZATION. WITH FAVORABLE DEEP LAYER SHEAR IN PLACE...THIS
   WILL LIKELY HAVE THE EFFECT OF STRENGTHENING A FEW STORMS...WITH A
   POSSIBILITY OF A WIND AND ISOLATED TORNADO THREAT DEVELOPING. ANY
   TORNADO THAT MAY OCCUR WOULD LIKELY BE BRIEF AND WEAK.
