   AREAS AFFECTED...SOUTHERN/EASTERN LA INTO SOUTHERN MS

   CONCERNING...TORNADO WATCH 219...

   VALID 260457Z - 260630Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 219 CONTINUES.

   SUMMARY...ISOLATED DAMAGING WIND/TORNADO POTENTIAL CONTINUES ACROSS
   SOUTHERN/EASTERN LA INTO PORTIONS OF SOUTHERN MS THROUGH THE EARLY
   PART OF THE OVERNIGHT. TORNADO WATCH 219 CONTINUES UNTIL 10Z.

   DISCUSSION...A SQUALL LINE CONTINUES TO STEADILY PROGRESS
   EAST-SOUTHEASTWARD ACROSS NORTHEAST/EAST-CENTRAL/SOUTHWEST LA AS OF
   1145 PM CDT...WITH OTHER STRONG STORMS PRECEDING THE SQUALL LINE IN
   VICINITY OF A PRIOR OUTFLOW BOUNDARY/NORTHWEST-SOUTHEASTWARD ARCING
   EFFECTIVE WARM FRONT. THE MOST INTENSE STORMS CAPABLE OF WIND
   DAMAGE/SOME TORNADO RISK WILL LIKELY CONTINUE ESPECIALLY AS THE
   SQUALL LINE INTERACTS WITH THE AFOREMENTIONED EFFECTIVE WARM FRONT
   ACROSS FAR NORTHEAST LA/SOUTHWEST MS SOUTHWARD INTO THE VERY
   MOIST/UNSTABLE AIR MASS ACROSS FAR SOUTHERN MS. THE SQUALL LINE MAY
   ESPECIALLY BEGIN TO WEAKEN INTO SOUTH-CENTRAL MS AS IT ENCOUNTERS A
   MORE STABLE BOUNDARY LAYER...ALTHOUGH SOME AIR MASS RECOVERY IS
   OCCURRING JUST ABOVE THE SURFACE VIA A SOUTH-SOUTHWESTERLY INFLUX OF
   VERY MOIST/UNSTABLE AIR.
