SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON TX
330 AM CDT TUE MAY 30 1995

SE TX ATMOSPHERE CONTINUES MOIST (BUT NOT AS MOIST AS YESTERDAY) AND
UNSTABLE AS WEAK STATIONARY FRONT REMAINS NEAR THE AREA.  LATEST 88D
AND SATELLITE PICTURES SHOW A LARGE RW/TRW COMPLEX APPROACHING FROM
THE W AND ISOLATED RW/TRW POPPING S OF IAH.  THINKING IS THAT RW/TRW
WILL INCREASE ACROSS SE TX THROUGH MID MORNING THEN DECREASE (MOVE TO
THE E) AS THE DAY PROGRESSES.  WITH SPOTTY VERY HEAVY RAINFALL TOTALS
FROM YESTERDAY AND COORDINATION WITH SAT AND LCH OFFICES...WILL HAVE
A FLASH FLOOD WATCH IN EFFECT TODAY GENERALLY NORTH OF INTERSTATE 10
WHERE FFG VALUES APPEAR TO BE REACHABLE.  COASTAL COUNTIES HAVE THE
HIGHEST FFG NUMBERS (NEAR 5 INCHES) SO WILL LEAVE THEM OUT OF THE
WATCH.  WITH FRONT REMAINING NEAR SE TX THROUGH WED...WILL LEAVE RAIN
CHANCES IN THE FORECAST.  WILL NOT STRAY TOO FAR FROM MOS TEMPS.

HEAVY RAIN OUTLOOK
NATIONAL WEATHER SERVICE HOUSTON TX
330 AM CDT TUE MAY 30 1995

THERE IS A RISK OF ADDITIONAL HEAVY RAINFALL TODAY FOR ALL OF SOUTHEAST
TEXAS.

HEAVY RAIN IS EXPECTED TO REDEVELOP OVER MUCH OF SOUTHEAST TEXAS TODAY.  AS
OF 3 AM...THE LEADING EDGE OF A LARGE AREA OF SHOWERS AND THUNDERSTORMS WAS
LOCATED FROM NEAR A COLLEGE STATION TO COLUMBUS LINE...WHILE OTHER
THUNDERSTORMS HAD DEVELOPED FROM NEAR SEALY TO FREEPORT.  ABUNDANT LOW
LEVEL MOISTURE...A SERIES OF UPPER LEVEL DISTURBANCES AND A WEAK STATIONARY
FRONT JUST NORTH OF THE AREA WILL INTERACT TO PRODUCE WIDESPREAD SHOWER AND
THUNDERSTORM ACTIVITY TODAY.

MID LEVELS OF THE ATMOSPHERE ARE SATURATED...SO THE POTENTIAL FOR HEAVY
RAIN EXISTS.  UPPER LEVEL WINDS ARE WEAK PRODUCING SLOW MOVING STORMS.  IN
ADDITION...WEAK WINDS ALOFT ALLOW STORMS TO REDEVELOP OVER THE SAME AREA
FOR AN EXTENDED PERIOD OF TIME WHICH WHICH LIKELY YIELD VERY HEAVY RAINFALL
TOTALS.  RAINFALL AMOUNTS OF 1 TO 3 INCHES ARE EXPECTED WITH TODAYS
THUNDERSTORM ACTIVITY.

THE GROUND IS ALREADY SATURATED FROM PREVIOUS RAINS.  ADDITIONAL RAINS
TODAY WILL CAUSE RIVERS AND STREAMS TO RISE...POSSIBLY FLOODING LOW LYING
AREAS.

EMERGENCY MANAGEMENT OFFICIALS AND STORM SPOTTERS SHOULD MONITOR THIS
WEATHER SITUATION CLOSELY.  STAY TUNED TO NOAA WEATHER RADIO OR OTHER NEWS
SOURCES FOR FURTHER UPDATES.
