AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
240 AM CDT SUN OCT 18 1998

UPPER LEVEL TROF OVER CENTRAL U.S. TO CONTINUE LIFTING NORTHEAST AND
FILLING TODAY...WITH WEST SOUTHWEST FLOW TO CONTINUE ACROSS THE REGION
THROUGH THE END OF THE PERIOD (HOWEVER THE ETA WANTS TO MAKE THE UPPER
WINDS MORE WESTERLY AND DRY OUT THE THE COLUMN MORE...MUCH AS THE LAST
LAST SYSTEM DID...HOWEVER PROBABLY SOMETHING IN BETWEEN WILL ACTUALLY
HAPPEN). AT ANY RATE RAIN WILL CONTINUE ALONG AND AHEAD OF A SLOW MOVING
COLD FRONT THAT EXTENDS THIS MORNING FROM NORTHWEST AR TO NEAR ACT ON
INTO SOUTHWEST TX. EXPECT FRONT TO EXTEND FROM NEAR MLU TO LFK BY 19/00Z
AND GOING STATIONARY SOMEWHERE FROM NEAR JAN TO NEAR HOU BY END OF THE
PERIOD. UPPER LEVEL DIVIGERENCE ALSO TO CONTINUE ACROSS THE CWA TODAY
AND TONIGHT AS RRQ OF JET MOVES SLOWLY ACROSS. MID AND UPPER LEVEL
TROPICAL MOISTURE CONTINUES TO FLOW INTO THE AREA FROM THE TROPICAL
PACIFIC. AS FRONT CONTINUES TO MOVE ON THE EAST END OVER RUNNING
SHOULD SET UP AT LEAST TONIGHT AND EARLY MONDAY FOR A COUPLE
HUNDRED MILES BEHIND THE FRONT. MAY NEED TO MENTION HEAVY RAIN
TODAY OVER PORITONS OF TX AND LA...BUT THE TORRENTIAL RAINS SHOULD
REMAIN OVER SOUTH AND SOUTHEAST TX. WITH RAIN AND CLOUDS TODAY
TEMPS WILL NOT CLIMB VERY FAR...THEREFORE WILL STICK CLOSE TO
QUIDANCE TEMPS. WILL GO ALONG WITH THE WETTER NGM/AVN AND CARRY
SOME POPS INTO MONDAY AND MONDAY NIGHT. BAND OF HEAVY RAIN FROM
SOUTH OF PALESTINE TO SOUTH OF WACO CONTINUES TO MOVE EAST
NORTHEAST AND SHOULD MOVE ACROSS THE SOUTHERN PORTIONS OF NORTHEAST
TX AND INTO NORTH LA THIS MORNING. SO WILL NEED TO MENTION A CHANCE
OF HEAVY RAIN AT LEAST THIS MORNING IN THOSE AREAS.
