AREAS AFFECTED...ERN TX...LA...SRN MS...SWRN AL

CONCERNING...SEVERE THUNDERSTORM WATCH 348...350...

VALID 292320Z - 300045Z

STRONG STORMS APPEAR TO BE SLOWLY INCREASING ACROSS WATCH 348 FROM
THE MS RIVER TO SCNTRL MS AS MOIST AND UNSTABLE GULF AIR MASS IS
LIFTED ATOP RESIDUAL COLD POOL IN THE WAKE OF EARLIER MCS. A FEW OF
THESE STORMS COULD PRODUCE SMALL HAIL IN THE NEXT HOUR OR SO.

OF GREATER CONCERN IN THE SHORT-TERM IS AN AREA OF VIGOROUS ACTIVITY
ACROSS WILKINSON...FRANKLIN AND AMITE COUNTIES IN SWRN MS. CELL IN
WILKINSON COUNTY HAS RECENTLY TURNED TO THE RIGHT AND APPEARS TO BE
NEAR BOUNDARY INTERSECTION WHERE A WEAK SFC LOW WAS ANALYZED. THE
BOUNDARY THE CELL APPEARS TO BE TRACKING ALONG COULD BE A SOURCE OF
STRONG LOW LEVEL BAROCLINICITY AND...GIVEN HIGH MOISTURE CONTENT IN
THE BOUNDARY LAYER...TORNADO POTENTIAL MAY BE GREATER WITH THIS
STORM AS IT TRACKS OVER SWRN AMITE COUNTY AND THEN INTO EAST
FELICIAN PARISH IN LA. ANOTHER ROTATING STORM IS NOTED IN RADAR DATA
ACROSS SRN FRANKLIN AND NRN AMITE COUNTY. THIS ACTIVITY MAY BE NORTH
OF THE SFC BOUNDARY WHERE INSTABILITY IS MORE LIMITED BUT COULD
STILL POSE A SEVERE THREAT AS IT MOVES EAST.

ACROSS WRN PARTS OF LA...ACTIVITY REMAINS LIMITED ATTM.
HOWEVER...MODEST CONVERGENCE ALONG GULF BREEZE/OUTFLOW BOUNDARY...
AND PRESENCE OF STRONG AND WEAKLY CAPPED INSTABILITY... WILL
CONTRIBUTE TO TSTM DEVELOPMENT POTENTIAL OVER THE NEXT 1-2 HOURS.
