PARIS TX TO TYLER TO COLLEGE STATION AND PROGRESSING STEADILY
EAST. AN OUTFLOW BOUNDARY PROCEDED SOUTHWARD THROUGH THE FOUR
STATE AREA AHEAD OF THIS FRONT...WHICH MAY STABILIZE THE AIR

QUITE A BIT OF SUNSHINE...SO THE ATMOSPHERE MAY DESTABILIZE AGAIN

LINE OF THUNDERSTORMS HAS FORMED ALONG THE COLD FRONT FROM
LONGVIEW TX...SOUTH TO JACKSONVILLE TX THIS AFTERNOON. WILL
INCLUDE THE MENTION OF SEVERE STORMS IN THE FORECAST FOR THIS
EVENING OVER THE EAST TEXAS AND NORTH LOUISIANA ZONES. WILL HAVE

MAIN THREAT FROM THE STORMS ALONG THE FRONT TONIGHT WILL BE LARGE
HAIL...WITH A MORE REMOTE CHANCE OF DAMAGING WINDS. THE RAIN WILL
MOVE EAST OF THE FOUR STATE AREA WEDNESDAY...WITH THURSDAY AND
FRIDAY BEING MOSTLY DRY. A STRONG UPPER LEVEL LOW IS PROGGED TO
