SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
257 PM CDT FRI SEP 21 2001

SO FAR...ISOLATED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS
SOUTHEAST TEXAS. EXPECT MORE ACTIVITY TO FORM DURING THE REMAINDER
OF THE AFTERNOON AND EVENING HOURS. SLOW STORM MOTION FAVORS LOCALLY
HEAVY RAINFALL (2 TO 4 INCHES IN THE STRONGER STORMS) AND DYNAMICS
ARE STILL STRONG ENOUGH FOR SOME SEVERE THUNDERSTORMS (DAMAGING
WINDS STILL GREATEST RISK). AFTER THIS EVENING...OUR BIG PROBLEM IS
TRYING TO TIME IMPULSES AND ASSOCIATED RAINS. SHORTWAVE ENERGY
LINGERS ACROSS EAST TEXAS THIS WEEKEND...AND THIS SHOULD ALLOW MORE
SHOWERS AND THUNDERSTORMS TO DEVELOP THROUGH THE PERIOD. WILL
GENERALLY CALL FOR 40% POPS THROUGH SUNDAY NIGHT. WILL NEED TO
EVALUATE SITUATION THROUGH THE WEEKEND FOR POSSIBLE CONTINUATION OF
SEVERE THUNDERSTORM RISK AND LOCALLY HEAVY RAINFALL THREAT.

STRONG COLD FRONT WILL SWEEP THROUGH SOUTHEAST TEXAS LATE SUNDAY
NIGHT AND EARLY MONDAY MORNING. MUCH DRIER AND COOLER FALL AIR WILL
SWEEP INTO SOUTHEAST TEXAS BEHIND THE FRONT ON MONDAY AS A GREAT
LAKES TROF DEEPENS SHARPLY AND EVENTUALLY BECOMES A CUTOFF LOW.
EXPECT SUNNY MILD DAYS AND CLEAR COOL NIGHTS FOR TUESDAY THROUGH
FRIDAY WITH LOWS GENERALLY IN THE 50S TO AROUND 60 AND HIGHS AROUND
80. FMR DATA IS FLIRTING WITH RECORD LOWS ON TUESDAY AND WEDNESDAY
MORNING. FOR NOW...WILL NOT GO THAT COLD (RECORD LOW AT IAH FOR
TUESDAY THE 25TH IS 50 AND FOR WEDNESDAY THE 26TH IS 49). THE COOL
AIR IS COMING

42/47/DO/30/38

.HGX...NONE.
