SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
315 AM CDT FRI SEP 27 1996

MASSIVE AFOS PROBLEMS AND VERY LIMITED DATA TO WORK WITH.

DUE TO DELAYS--WILL KEEP IT SHORT...VERY HEAVY RAINS HAVE OR ARE
STILL FALLING NORTH OF A MADISONVILLE-HUNTSVILLE-SHEPARD-LIVINGSTON
LINE.  NESDIS RAINFALL ESTIMATIONS RANGING FROM 3 TO 6 INCHES. 88D
ESTIMATES RUNNING SHY BASED ON PRELIM REPORTS.  APPEARS THAT
LIVINGSTON COUNTY MAY HAVE RECIEVED IN EXCESS OF 7 INCHES.  CXO ASOS
REPORTED 0.41 INCH OF RAIN IN 5 MINUTES AT 315 AM. FRONT APPEARS TO
HAVE SLOWED DRAMATICALLY IN RESPONSE TO DIGGING S/W OVER THE ROCKIES.
THIS HAS PROMPTED A FLASH FLOOD WATCH FOR ALL OF SETX.  SLUG OF
MOISTURE (PER WATER VAPOR) MOVING UP THE COAST TOWARD THE WATCH AREA
SO WOULD EXPECT REDEVELOPMENT/INTENSIFICATION TO THE SOUTH.  FOR
FURTHER MET REASONING SEE SAT SFD.  HIGH POPS WARRANTED FOR TODAY
WITH COOLER TEMPS DUE TO PRECIP AND CLOUD COVER.  FRONT SHOULD MOVE
OFF THE COAST LATE AFTERNOON/EARLY EVENING...BUT PREFRONTAL ACTIVITY
WILL LIKELY CONFUSE THIS ISSUE.  VERY STRONG OFFSHORE FLOW
TONIGHT/SATURDAY WILL REQUIRE A GALE WARNING FOR THE NEARSHORE WATERS.

THANKS SAT FOR THE BRIEFING AND ASSISTANCE...MUCH APPRECIATED!
