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.
