The episode as NWS HGX wrote it up.
A severe thunderstorm developed in the evening and produced large hail.
The local office's own words before the first event, 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 the first event at May 30, 5:24 PM CST, 1 hour 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 624 PM CDT SUN MAY 30 2010 .AVIATION... SHRA/TSRA DEVELOPMENT WILL REMAIN POSSIBLE FOR SEVERAL MORE HOURS ALONG OUTFLOW BOUNDARIES GENERATED FOR EARLIER ACTIVITY. COULD SEE SOME PATCHY FOG TOWARD MORNING AT CXO AND LBX. QUIET TOMORROW UNTIL DAYTIME HEATING HELPS TO GENERATE SHRA/TSRA ONCE AGAIN. NOT SURE HOW MUCH COVERAGE WE'LL SEE...SO WILL JUST MENTION CB IN AREA TAFS FOR THE AFTERNOON HOURS. BEGINNING AROUND JUNE 2ND...THERE WILL BE A PLANNED OUTAGE AT LBX. TAF NIL WILL BE ISSUED WHEN THE OUTAGE BEGINS...AND THE LBX TAF WILL REMAIN NIL UNTIL ASOS SERVICE IS RESTORED.

SOUTHEAST TEXAS BEING PINCHED BY AN MISSISSIPPI UPPER LOW AND A SOUTHERN TEXAS SHORTWAVE DISTURBANCE. THIS HAS INCREASED CONVECTIVE ACTIVITY WITHIN THE PERSISTENT 7H STEERING FLOW. A FEW OF THESE STORMS ARE STRONG PULSERS AND WILL SPIT OUT PLUS-40 MPH DOWNDRAFTS AND PENNY (TO QUARTER) SIZE HAIL ON THEIR SOUTHERN TREK. ONCE DAYTIME HEATING IS LOST...EXPECT ANY LINGERING ACTIVITY TO DWINDLE OUT BY 9 OR 10 PM INTERIOR...POSSIBLY HANGING ON A BIT LONGER OVER MARITIME AREAS. THERE IS NO REASON TO BELIEVE THAT WE WILL NOT EXPERIENCE ANOTHER DAY OF THIS ISOLATED CONVECTION ON MEMORIAL DAY. THUS...IF PLANNING ANY OUTDOOR ACTIVITIES...IT BE BEST TO CHECK OUT TOMORROW MORNING'S AFD/HWO/ZFP BEFORE SETTING OUT. AS THE MS LOW DISSOLVES INTO AN OPEN WAVE LATE TOMORROW AND TUESDAY...TRANSITORY RIDGING WILL MOVE OVER THE STATE. DOESN'T MEAN MUCH OTHER THAN THE FACT THAT THE MESOSCALE BREEZE MAY BE MORE OF A PLAYER IN THE LOCATION OF THOSE HEAT-OF-THE-DAY THUNDERHEADS. ANY CONVECTION THAT FIRES ALONG THE BREEZE MAY FALL BACK TOWARDS THE COAST...OR CONCENTRIC OUTFLOW FROM MAIN CORES MAY INITIATE DOWNSTREAM STORMS OVER OUR LOCAL LAKES/BAYS/NEAR SHORE GULF WATERS.
