SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
911 PM CDT MON MAY 1 2000

UPPER LOW WAS CURRENTLY OVER THE CENTRAL KS/OK BORDER.  SHORTWAVE
TROUGH WAS ALSO PUSHING AROUND THE SOUTHERN SIDE OF THE LOW...MOVING
INTO SOUTHERN TEXAS.  AREA SOUNDINGS...INCLUDING THE ACARS/MAPS
SOUNDING FOR IAH...ALL SHOW CAPES NEAR OR EXCEEDING 3000 FOR MUCH OF
SETX.  WITH THIS IN MIND FEEL THAT THE HIGH POPS FOR THE AREA ARE
WARRANTED...INCLUDING THE MENTION OF SEVERE AND HEAVY RAINFALL.
STRONG THUNDERSTORMS WERE DEVELOPING JUST WEST OF GRK AT THE MOMENT.
THESE STORMS WERE DEVELOPING ALONG A SURFACE TROUGH/OUTFLOW BOUNDARY.
SURFACE DEWPOINTS ALONG AND AHEAD OF THE BOUNDARY WERE IN THE MID 60S.
ALSO...SOUTHEASTERLY WINDS WERE FEEDING GULF MOISTURE INTO THE
DEVELOPING STORMS.  A SIDE NOTE...THE HGX VWP WAS SHOWING SOUTHWEST
WINDS NEAR THE SURFACE...MORE THAN LIKELY THE RESULT OF MIGRATING
BIRDS CONTAMINATING THE ALGORITHM RESULTS.

SO...THE CONCLUSION OF THE MATTER IS THAT ANOTHER ROUND OF
THUNDERSTORMS ARE EXPECTED.  WILL NOT GO WITH A FLASH FLOOD WATCH AT
THIS TIME...THOUGH RAINFALL AMOUNTS COULD REACH 1 INCH OR SO OVER A
WIDE AREA.  LOCATIONS THAT LOOK TO GET THE HEAVIER RAIN AMOUNTS WILL
BE THE FAR NORTHERN COUNTIES OF THE FORECAST AREA.

TEMPERATURES AND WINDS ARE THE MOST DIFFICULT OF THE VARIABLES TO
FORECAST TONIGHT.  GIVEN THE CURRENT DEWPOINTS FEEL THAT THE FORECAST
MINS ARE OKAY.  WINDS ARE ANOTHER MATTER.  VARIABLE TO SOUTHEAST WINDS
SHOULD OCCUR AHEAD OF THE THUNDERSTORMS...WITH NORTH WINDS IN ITS
WAKE.

WILL ONLY MAKE MINOR CHANGES TO THE COASTAL FORECAST.

.KHGX...NONE.
