   AREAS AFFECTED...SRN AND CNTRL MS...SE LA
   
   CONCERNING...TORNADO WATCH 2...
   
   VALID 050456Z - 050630Z
   
   THE TORNADO THREAT WILL CONTINUE ACROSS TORNADO WATCH 2 OVER THE
   NEXT SEVERAL HOURS. ALSO...THE TORNADO THREAT SHOULD EXPAND ENEWD
   CNTRL MS.
   
   A LINE OF THUNDERSTORMS IS INCREASING IN INTENSITY AND IS LOCATED
   ALONG THE INTERSTATE 55 CORRIDOR FROM NEAR LAKE PONTCHARTRAIN IN SE
   LA NWD INTO SWRN MS. LATEST SFC ANALYSIS SHOWS THAT DEWPOINTS AHEAD
   OF THE LINE HAVE RISEN OVER THE LAST HOUR WITH JACKSON MS AND
   MERIDIAN MS BOTH AT 66 F.  THIS IS A RESULT OF SSELY FLOW NEAR THE
   SFC WHICH IS TRANSPORTING LOW-LEVEL MOISTURE NWD ACROSS SCNTRL MS.
   IN ADDITION...A 45 KT LOW-LEVEL JET IS LOCATED ACROSS SCNTRL MS
   WHICH IS CREATING VERY STRONG LOW-LEVEL SHEAR PROFILES. ALTHOUGH
   INSTABILITY IS RELATIVELY WEAK...THE SHEAR PROFILES COMBINED WITH
   LCL HEIGHTS BELOW 500 METERS WILL BE FAVORABLE FOR ROTATING STORMS
   AND TORNADOES AS THE CONVECTIVE LINE MOVES EWD TONIGHT. WIND DAMAGE
   WILL ALSO BE POSSIBLE WITH THE BETTER ORGANIZED STORMS EMBEDDED IN
   THE LINE.
