Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
337 AM CDT SUN MAY 25 2003

CLUSTERS OF STRONG THUNDERSTORMS CONTINUE TO DEVELOP AS COLD FRONT
AND LARGE MCS INTERACT WITH MOIST AND UNSTABLE AIR ACROSS THE
REGION. APPEARS THAT THE MCS IS EVOLVING INTO MORE OF A HEAVY RAIN
EVENT...WITH SOME LOCAL FLOODING OF LOW SPOTS LIKELY. ETA FORECAST
SOUNDINGS SHOW OVER 1.5 INCHES OF PW INTO THIS AFTERNOON...BUT FEEL
A FLOOD WATCH MAY BE A BIT TOO AGGRESSIVE AS MANY AREAS STILL NEED
SOME GOOD RAIN. COLD FRONT WILL CONTINUE SLIDE SW INTO N TEXAS THIS
AFTERNOON AND STORMS WILL LIKELY REDEVELOP ALONG THE BOUNDARY AND
MOVE SOUTHEAST ACROSS MAINLY OUR SOUTHERN ZONES LATE THIS AFTERNOON
AND TONIGHT. STILL WILL BE A THREAT OF SEVERE STORMS THIS AFTERNOON
AND TONIGHT AS CAPE FORECAST REMAINS SOMEWHAT HIGH (1500-2000 J/KG
ACROSS THE SPC DAY ONE OUTLOOK AREA).

FRONT IS EXPECTED TO STALL AND WASH OUT ACROSS OUR EXTREME SOUTHERN
CWA MONDAY AFTERNOON...WITH SOME LIMITED ISENTROPIC LIFT AND WEAK
IMPULSES ALOFT PROVIDING SOME CHANCE OF LINGERING PRECIP INTO
TUESDAY. OTHERWISE...NEW GFS CONTINUES TO SHOW A RIDGE BUILDING INTO
THE CENTRAL PLAINS. THIS SHOULD WARM N TEXAS AND END THE PRECIP
CHANCES FOR SEVERAL DAYS. RIDGE LOOKS TO BREAK DOWN LATE IN THE
EXTENDED PERIOD AS FLOW BECOMES MORE PROGRESSIVE...FOLLOWED BY A
WEAK TROUGH ACROSS THE CENTRAL U.S..
