SOUTHEAST TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 215 PM CDT THU SEP 20 2001 EAST-WEST ORIENTED LINE OF STORMS FROM FWD AREA TO SHV AREA SAGGING SOUTHWARD. WEAKENING TREND HAS BEEN NOTED IN THE LAST SEVERAL RADAR SCANS. BIG SHORT TERM PROBLEM FOR OUR AREA IS THE DIFFICULTY IN TIMING THE SHORTWAVES (TONIGHT THROUGH THE WEEKEND) THAT WILL BE STARTING TO CARVE OUT A CENTRAL TO EASTERN U.S. TROF. WITH HIGH PRECIP WATER VALUES...LOW LIS...AND HIGH TOTAL TOTALS AND CAPES... WILL CALL FOR SLIGHTLY HIGHER POPS STARTING TOMORROW AND ON THROUGH THE WEEKEND. PRESENT THINKING IS THAT AREAS ALONG AND WEST OF HIGHWAY 59 (ALONG AND WEST OF A LIVINGSTON TO HOUSTON TO EDNA LINE) HAVE THE GREATEST RISK FOR SHOWERS AND THUNDERSTORMS DURING THE NEXT 3 DAYS. DEVELOPING EASTERN U.S. TROF AND WESTERN U.S RIDGE WILL HELP SWEEP A COLD FRONT THROUGH SOUTHEAST TEXAS LATE SUNDAY NIGHT AND ON INTO EARLY MONDAY MORNING. AT THIS TIME...IT APPEARS THAT SIGNIFICANT DRYING WILL DEVELOP LATE ON MONDAY AS THE FRONT MAKES IT WELL OFFSHORE (AVN PLUNGES IAHS PRECIP WATER VALUES TO UNDER .5 INCHES BY TUESDAY MORNING). NEXT WEEK LOOKS TO BE COOL AT NIGHT (INLAND LOWS FINALLY DROPPING INTO THE 50S) AND MILD DURING THE DAY (HIGHS IN THE UPPER 70S TO LOWER 80S). HAVE LEANED A LITTLE CLOSER TO THE WARMER OVERNIGHT LOWS OF THE MEX. ALSO...EXPECT BREEZY CONDITIONS ALONG THE COAST ON MONDAY AFTER FRONTAL PASSAGE. 42/47/DO .HGX...NONE. PRELIMS...
