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 SHREVEPORT LA
448 AM CDT TUE JUL 5 2005

.DISCUSSION...
EARLY THIS MORNING A FRONTAL SYSTEM EXTENDED ACROSS W AR INTO SE OK
AND NORTH TX AND SHOWERS AND THUNDERSTORMS CONTINUED TO FIRE ALONG
AND NEAR THE SYSTEM OVER N TX...SE OK...AND SW AR. THIS FRONT WILL
CONTINUE A SLOW DRIFT SOUTH AS UPPER DISTURBANCES MOVE THROUGH THE
NW FLOW ALOFT AROUND UPPER HIGH TO THE SW AND TROUGH OVER THE CENTRAL
SECTIONS OF THE COUNTRY. THIS UPPER PATTERN WILL HOLD THROUGH
MUCH OF THE WEEK AND CONTINUE TO PROVIDE A CHANCE OF SHOWERS AND
THUNDERSTORMS EACH DAY BUT WITH LOWER CHANCES DUE TO TROPICAL
SYSTEM MOVING INTO SE LA AND THEN INTO THE TN VALLEY KEEPING
MOISTURE OFF TO THE EAST. THE UPPER RIDGE OF HIGH PRESSURE OUT
TO THE WEST AMPLIFIES INTO THE CENTRAL AND N SECTIONS OF THE
NATION TOWARD THE WEEKEND AND PROVIDES THE FOUR STATE REGION WITH
A DRY PERIOD. BY LATE WEEKEND AND INTO EARLY NEXT WEEK...MODEL DATA
INDICATES THE NEXT TROPICAL SYSTEM MOVING INTO THE EASTERN GULF AND
WEST TOWARD THE CENTRAL GULF COAST. HAVE MADE CHANGE TO THE EXTENDED
TO ACCOUNT FOR THIS POSSIBILITY.
