SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
945 AM CST SUN NOV 12 2000

PARTLY CLOUDY OVER THE SRN HALF AND CLOUDY OVER THE NRN HALF OF SERN
TX AT MID MORNING. FOG SHOULD LIFT AT REMAINING LOCATIONS BY 11 AM.
THE MAIN UPDATE ISSUES ARE SEVERE THREAT... POPS...AND TEMPS. PER
COORD CALL WITH SPC...THE SEVERE THREAT SEEMS HIGHER THAT PREVIOUSLY
THOUGHT...ESPECIALLY WITH CLEARING SKIES AND STRONG MOIST ADVECTION
OCCURRING IN THE SRN HALF OF THE AREA. SO WILL UPDATE THE ZONES AND
SPS TO ADD SEVERE WORDING IN LINE WITH NEW SPC SWODY1.
SIMILARLY...EARLIER UPDATE FOR HIGHER POPS LOOKS GOOD... NO CHANGES
THERE. FINALLY...TEMPS WILL NEED UPDATING IN THE COASTAL AND CNTRL
ZONES AS GLS IS ALREADY ABOVE ITS FORECAST HIGH. THE NRN ZONES WILL
LIKELY HOLD ON TO ENOUGH CLOUDCOVER...AND PRECIP WILL START EARLY
ENOUGH...TO HOLD HIGHS AT CURRENT FORECAST.

THANKS FOR COORD SPC.

.KHGX...SCEC TODAY...SCA LIKELY TONIGHT FOR ALL BAYS AND GULF WATERS.

...SEVERE STORMS POSSIBLE FROM MID AFTERNOON THROUGH LATE EVENING...

MOIST GULF AIR...A STRONG JETSTREAM...AND A COLD FRONT WILL
COMBINE TO PRODUCE SHOWERS AND THUNDERSTORMS ACROSS SOUTHEAST
TEXAS LATE THIS AFTERNOON AND TONIGHT. THE STRONG WINDS ALOFT...
TURNING WIND DIRECTION AS ALTITUDE INCREASES...AND MODERATE TO HIGH
INSTABILITY INDICATE THE POTENTIAL FOR SOME STORMS TO BECOME SEVERE
AND PRODUCE DAMAGING WINDS OR ISOLATED TORNADOES. IN ADDITION...THE
SLOW MOVEMENT OF THE COLD FRONT INDICATES STORMS MAY PASS OVER THE
SAME AREA...PRODUCING HEAVY RAIN. HEAVY RAIN WILL RUNOFF QUICKLY SINCE
THE GROUND IS SATURATED FROM HEAVY RAIN OVER THE PAST TWO WEEKS.

THE MAIN THREAT AREA FOR SEVERE STORMS IS ALONG AND SOUTHWEST OF
INTERSTATE 45. THIS INCLUDES HUNTSVILLE...BRYAN...COLLEGE STATION...
CONROE...METRO HOUSTON...GALVESTON...BRENHAM...COLUMBUS AND WHARTON.

HEAVY RAIN IS POSSIBLE THROUGHOUT ALL OF SOUTHEAST TEXAS FROM LATE
AFTERNOON OVERNIGHT. RAINFALL TOTALS ARE FORECAST TO AVERAGE AROUND 1
INCH...WITH A FEW SPOTS RECEIVING 2 TO 3 INCHES.

AFTER THE SHOWERS AND THUNDERSTORMS END MONDAY MORNING...HIGH
PRESSURE WILL BRING COLD...DRY AIR INTO SOUTHEAST TEXAS. LOW
TEMPERATURES MONDAY AND TUESDAY NIGHTS WILL RANGE FROM THE LOWER TO
MID 30S NORTH OF INTERSTATE 10...WITH MID TO UPPER 30S TO THE SOUTH.
MAKE PLANS NOW TO COVER OR BRING IN DELICATE PLANTS.
