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.
