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.

430 AM CDT SAT AUG 30 2003

CHANCES OF RAIN WILL REMAIN HIGH AS LONG AS SURFACE BOUNDARY LINGERS
AROUND THE AREA. ALSO...THE SYSTEM COMING UP FROM THE SOUTH WILL
KEEP POPS UP. MUCH MOISTURE WILL BE IN PLACE TO PRODUCE HEAVY
RAIN...ESPECIALLY OVER NORTHWEST ARKANSAS TODAY AND NORTHERN
ARKANSAS TONIGHT. HEAVY RAINS WILL CONTINUE TO BE A POSSIBILITY FOR
THE LATTER HALF OF THE WEEKEND...AND IT WILL HAVE TO BE MONITORED
FOR POSSIBLE FLASH FLOOD WATCH. CLOUDS AND RAINS WILL MAKE TEMPS
DIFFICULT TO PEG. ANY BREAK IN THE CLOUDS WILL ALLOW TEMPS TO BOOM
AS WAS THE CASE YESTERDAY.

AFTERNOON AND EVENING. THE PRIME SEVERE WEATHER THREATS WOULD BE
STRONG AND DAMAGING WINDS...AND POSSIBLY ISOLATED TORNADOES.

NORTHERN ARKANSAS MAY CAUSE PROBLEMS ALONG SOME RIVERS IN NORTHERN
ARKANSAS.
