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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
328 PM CDT WED 04 JUN 2003

SEVERAL BOUNDARIES WERE OBSERVED ACROSS THE PANHANDLE REGION AND
AIDING WITH CONVECTIVE INITIATION...ESPECIALLY OVER THE WESTERN
AREAS. SHEAR PROFILES SUGGEST THE LIKELIHOOD OF SUPERCELLS. IN
ADDITION...LOW LEVEL CONVERENCE AND DEEPER MOISTURE WILL CONTRIBUTE
TO HEAVY RAINFALL. AS SHORTWAVE ENERGY CONTINUES TO STREAM FROM THE
NORTHWEST...THUNDERSTORMS WILL PERSIST INTO THE NIGHTTIME. FLASH
FLOOD WATCH IS IN EFFECT FOR ALL THE AREA TONIGHT...AND A TORNADO
WATCH WILL BE ISSUED FOR THE WESTERN PORTIONS THROUGH THIS EVENING.

WITH THIS PATTERN FIXED THROUGH AT LEAST THE WEEKEND...HEAVY RAIN
POTENTIAL WILL ALSO BE A CONCERN.
