Severe Thunderstorm Warning 23, NWS Shreveport, LA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
1025 AM CST FRI MAR 10 2000

WIND SHIFT/FRONTAL BOUNDARY ALONG AR...LA BORDER AND EXTENDS TO JUST
SOUTH OF TERRELL TEXAS. NEW THUNDERSTORM ACTIVITY IS DEVELOPING ALONG
THIS BOUNDARY AND AS AFTERNOON INSTABILITY BECOMES A FACTOR LOOK FOR
MORE STORM TO BECOME SEVERE. WIND PROFILES DO NOT SHOW MUCH
SHEAR...BUT STORM INTERACTION WITH THE FRONTAL BOUNDARY AS IT BEGINS
TO MOVE SOUTHEAST COULD PROVIDE ROTATION. FORECAST TIMING STILL LOOKS
GOOD WITH NEW ETA RUN SO CHANGES TO ZONES AT THIS TIME WILL BE
MAINLY FOR WORDING. MID 80S ACROSS SOUTHERN COUNTIES AND PARISHES
STILL POSSIBLE...BUT CONSIDERABLE CLOUDINESS SHOULD HOLD THEM AT
THAT LEVEL.

ZONE UPDATE SHOULD BE BE OUT BETWEEN 11 AND 1130.

.SHV...NONE.
