Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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.

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 Fort Worth, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at May 30, 9:13 PM CDT, 46 minutes earlier.

Area forecast discussion, May 30, 9:13 PM CDT, 46 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE FORT WORTH TX
913 PM CDT SUN MAY 30 2004

.UPDATED DISCUSSION...
HAVE UPDATED ZONES TO LOWER POPS MOST LOCATIONS...BUT KEPT THEM
FAIRLY HIGH ALONG AND SOUTHEAST OF THE SLOWING COLD FRONT.
CONVECTION HAS SHOWN A GENERAL DECREASE IN INTENSITY AND COVERAGE
THE LAST 30 MINUTES...AND THIS IS LIKELY DUE TO DECREASED
CONVERGENCE WITH THE SLOWING OF THE COLD FRONT AND DIMINISHED
INSOLATION. QUESTION REMAINS...WILL LLJ BE ENOUGH TO EXCITE NEW
DEVELOPMENT LATER TONIGHT...OR WILL IT KEEP CONVECTION GOING AFTER A
SHORT PAUSE. PALESTINE PROFILER AT 01Z ONLY HAD 25 KT WINDS AT
925MB...SO OUR INITIAL THOUGHTS ARE THAT THE CONVECTION WILL SLOWLY
DIMINISH AND THEN REFIRE TOMORROW AFTERNOON AS SURFACE FRONT
INTERACTS WITH A GOOD DEAL OF INSTABILITY AND A WEAK CAP. TEMPS LOOK
REASONABLE AND NO OTHER MAJOR ADJUSTMENTS HAVE BEEN MADE ATTM. 80

&&

.PREVIOUS DISCUSSION...
AS OF 20Z...THE COLD FRONT EXTENDED EAST OF A SHERMAN...TO MINERAL
WELLS...TO COLEMAN LINE. THE 18Z FWD RAOB INDICATED THAT A STUBBORN
CAP REMAINED IN PLACE. THUNDERSTORMS HAVE BEEN FIRING THIS AFTERNOON
TO THE NORTH AND NORTHEAST THE METROPLEX ALONG AND AHEAD OF THE
FRONT. GIVEN THE HIGH CAPES...THESE STORMS WILL HAVE THE POTENTIAL TO
BECOME SEVERE. THE THUNDERSTORM THREAT WILL CONTINUE INTO THE EAST
AHEAD OF  THE FRONT...WITH THE BEST CHANCES ACROSS THE NORTHEASTERN
ZONES. THE FRONT WILL CONTINUE TO SLOWLY MOVE SOUTHEAST TONIGHT...
AND SHOULD BECOME STATIONARY OVER OR JUST TO THE SOUTH OF THE
SOUTHERN ZONES MONDAY.  THIS FRONT WILL DRIFT BACK TO THE
NORTH ON TUESDAY. TEMPERATURE WISE...THIS FRONT WILL MAKE LITTLE
DIFFERENCE FOR THE HIGHS...WITH TEMPERATURES IN THE LOWER TO MID 90S
ACROSS MUCH OF THE FORECAST AREA MONDAY AND TUESDAY.  HAVE KEPT
LOW POPS IN THE EXTENDED PER THE PREVIOUS FORECAST.  #58
