What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Houston/Galveston, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at May 1, 9:11 PM CDT, 5 hours 55 minutes earlier.
Area forecast discussion, May 1, 9:11 PM CDT, 5 hours 55 minutes before
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. PL-40 45
