NWS Houston/Galveston, TX wrote its last area forecast discussion before this flash flood warning went out at Jul 14, 2:55 AM CDT, 6 hours 50 minutes earlier.

SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
255 AM CDT SUN JUL 14 2002

ATMOS HAS STABILIZED IN THE WAKE OF THE WIDESPREAD
CONVECTION DURING THE EVENING HOURS OVER SE TX. RECEIVED VERY
IMPRESSIVE RAINFALL RATES IN TROPICAL AIRMASS WHICH LED TO FLASH
FLOODING IN WHARTON COUNTY AND URBAN STREET FLOODING IN HARRIS
COUNTY.

MAIN ISSUE FOR THE UPCOMING PACKAGE IS HEAVY RAIN/FLOODING THREAT.
OVERALL SYNOPTIC SITUATION CHANGES LITTLE TODAY AND TONIGHT AND FOR
THAT REASON WILL FORECAST LIKELY POPS ALL AREAS TODAY. MESOSCALE
BOUNDARIES WILL DICTATE WHO RECEIVES THE MOST RAINFALL TODAY AND
TONIGHT. WILL THEREFORE NOT TRY TO SELECT ANY FAVORED AREAS WHEN PW
VALES ARE A LITTLE OVER 2 INCHES AREAWIDE. SHORT WAVE ENERGY WILL
CONTINUE TO ROTATE AROUND THE UPPER LOW AND MOVE ACROSS FA THROUGH
MONDAY. SO ONCE ATMOSPHERE RECOVERS...SHWRS AND TSTMS SHOULD
BEGIN TO DEVELOP OVER THE AREA. BELIEVE SCT SHWRS AND TSTMS WILL
DEVELOP SOMETIME THIS MORNING AND COVERAGE WILL INCREASE DURING THE
AFT/EVE HOURS. BELIEVE FLASH FLOOD WATCH IS A GOOD IDEA. HOWEVER...I
HAVE DECIDED TO INCLUDE ALL ZONES DUE TO THE POTENTIAL OF VERY HIGH
HOURLY RAINFALL RATES (4 INCHES/HR) AND THE POSSIBILITY OF
BACKBUILDING AND TRAINING AGAIN IN DIFFLUENT UPPER LEVEL FLOW.

TUE-FRI PERIOD OF THE FORECAST DOES NOT LOOK MUCH
DIFFERENT...ALTHOUGH I QUESTION HOW FAST TROPICAL MOISTURE WILL
ACTUALLY SHIFT NW OF REGION AS AVN IS ADVERTISING AND HAVE RAISED
TUES POPS ESPECIALLY FOR WESTERN ZONES. TEMPS ARE EXPECTED TO WARM
BACK INTO THE MID 90S ON WED.

THANKS LCH FOR COORD.
