Area forecast discussion, Nov 8, 3:06 PM CST, 21 minutes before

SOUTHEAST TEXAS AND SOUTHWEST LOUISIANA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
154 PM CST WED NOV 8 2000

AT 18Z....SFC LOW WAS LOCATED NEAR THE SABINE RIVER BETWEEN KLCH AND
KLFK WITH A TROF EXTENDING NORTH ALONG THE SABINE RIVER AND A WARM
FRONT EXTENDING FROM KPOE TO NORTHEAST LOUISIANA. THIS LOW AND
ATTENDANT FRONTS WILL SLOWLY MOVE TO THE EAST-NORTHEAST AS TIME
WEARS ON. THE MOVEMENT OF THE SFC FRONT IS HIGHLY DEPENDENT ON THE
500 MB LOW CURRENTLY LOCATED OVER SW TX. LOOKS LIKE THE ETA MODEL HAS
A GOOD HANDLE ON THIS SITUATION AND WILL GO WITH IT. THE 500 MB LOW
WILL LIFT SWIFTLY TO THE NORTHEAST AND WILL BE NEAR KSTL BY 18Z
THURSDAY. THE COLD FRONT IS ALREADY EAST OF THE TEXAS PART OF THE LCH
CWA. THE COLD FRONT SHOULD BE EAST OF THE LCH CWA BY 06Z THURSDAY.
EXTENSIVE CLOUD COVER AND PATCHY LIGHT RAIN CAN BE EXPECTED BEHIND
THE COLD FRONT DUE TO THE MOISTURE WRAPPING AROUND THE SFC LOW. SKIES
WILL CLEAR OUT ON THURSDAY AS THE SFC LOW WHISKS RAPIDLY OFF TO THE
NORTHEAST PULLING THE MOISTURE WITH IT.

TORNADO WATCH CONTINUES ACROSS MOST OF THE LA PORTION OF THE CWA
UNTIL 600 PM.

WILL GO AHEAD AND LET THE FLOOD WATCH EXPIRE NATURALLY. WHILE
THERE IS SOME TRAINING OF CELLS...THERE IS ENOUGH PROGRESS TO THE
EAST IN THE LINE TO PREVENT ANY FLOODING OF A SIGNIFICANT AREA. ONE
HOUR RAINFALL RATES ARE RANGING FROM AROUND .50 OF AN INCH TO 3
INCHES. THERE HAVE BEEN NO REPORTS OF FLOODING AT THIS TIME.

THE NEXT FORECAST PROBLEM IS THE TEMPERATURES. COLDER TEMPERATURES
WILL SPILL INTO THE AREA IN THE WAKE OF THE LOW PRESSURE SYSTEM AND
THE COLD FRONT. WILL GO WITH A BLEND OF NGM AND AVN TEMPS.
