.DISCUSSION...
SFC ANALYSIS SHOWS OUR WARM FRONT CREEPING NWD ACROSS THE NRN 1/2
OF THE AREA ATTM...WHILE WATER VAPOR IMAGERY SHOWS A PAIR OF
SHORTWAVES IMPACTING THE REGIONAL WEATHER THIS AFTERNOON. 1ST ONE
IS CROSSING THE FORECAST AREA ATTM...WHICH IS HELPING SPARK THE
CURRENT HAIL-PRODUCING CONVECTION OVER PARTS OF SWRN LA...WHILE
THE 2ND ONE IS CROSSING CNTL TX WHICH IS FIRING OFF MORE
CONVECTION OVER SRN/SERN TX.

MAIN CONCERNS THIS PACKAGE CENTER AROUND POPS IN THE EARLY PERIODS
AND TEMPS IN THE LATER PERIODS. RAIN CHANCES REMAIN IN THE
FORECAST THROUGH AT LEAST MONDAY AS A SERIES OF DISTURBANCES
ALOFT CONTINUE TO PASS THE REGION...HELPING FIRE SCATTERED
CONVECTION THROUGH THE PERIOD. AGAIN BEST POPS GENERALLY REMAIN
ACROSS THE SERN ZONES WHERE LIFT/MOISTURE ARE PROGGED TO BE BEST.
THE PRECIP/CLOUD COVER SHOULD KEEP TEMPS SOMEWHAT AT BAY WITH MAX
READINGS GENERALLY PUSHING 90 AT BEST INTO MONDAY.

DRY WEATHER IS THEN EXPECTED THROUGH THE REMAINDER OF THE COMING
WEEK AS RIDGING ALOFT BUILDS OVER THE REGION. THIS IN TURN WILL
LEAD TO A WARMING TREND WITH AFTERNOON HIGHS WELL INTO THE 90S BY
