The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

The nearest sounding before it

Dodge City, (KDDC), launched 12:00Z, 10.7 hours before the alert went out and 167 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Amarillo, TX wrote its last area forecast discussion before this flash flood warning went out at Aug 14, 3:04 PM CDT, 2 hours 38 minutes earlier.

Area forecast discussion, Aug 14, 3:04 PM CDT, 2 hours 38 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
304 PM CDT THU AUG 14 2008

.DISCUSSION...
SHORTWAVE TROUGH VISIBLE ON WATER VAPOR DROPPING SOUTHEAST OUT OF
COLORADO RIGHT NOW. STORMS BEGINNING TO DEVELOP ALONG AND HEAD OF THE
DISTURBANCE ALREADY. MINOR BOUNDARIES ACROSS THE CWA WILL ADD LOW
LEVEL CONVERGENCE AND ENHANCE LIFT FOR THUNDERSTORM DEVELOPMENT.
SEVERE THUNDERSTORM WATCH HAS JUST BEEN DROPPED FOR THE ENTIRE CWA
FOR TONIGHT AS STORMS SHOULD MOVE SOUTHEAST ACROSS THE AREA WITH A
DAMAGING WIND AND HAIL THREAT. HEAVY RAIN MAY ALSO BE A
CONCERN...ALTHOUGH STORMS SHOULD MOVE FAIRLY QUICKLY COMPARED TO
RECENT WEEKS. ANOTHER DISTURBANCE DROPS SOUTHEASTWARD BEHIND THE
INITIAL DISTURBANCE...AND THIS MAY BRING ANOTHER ROUND OF
THUNDERSTORMS AFTER MIDNIGHT TONIGHT.

LARGE UPPER LEVEL LOW IS STILL EXPECTED TO DROP SOUTH OR
SOUTHWESTWARD INTO COLORADO BY TOMORROW EVENING. PRETTY GOOD
AGREEMENT AMONG THE MODELS ON THIS SCENARIO...AND THE LOW IS EXPECTED
TO REMAIN IN THE SOUTHERN ROCKIES AND SOUTHERN PLAINS FOR SEVERAL
DAYS BEFORE FINALLY GETTING ABSORBED BY A LARGE UPPER TROUGH
APPROACHING THE WEST COAST LATER NEXT WEEK.

WITH THE UPPER LOW AROUND...TEMPERATURES WILL BE COOL AND
THUNDERSTORM CHANCES WILL BE IN THE FORECAST EVERY DAY. TEMPERATURES
MAY NOT GET OUT OF THE 70S FOR A FEW DAYS THIS WEEKEND DUE TO
EXTENSIVE CLOUD COVER AND COLD AIR ALOFT.

STAYED WITH THE 12Z MAV TEMPERATURES AND POPS...AND THE 00Z MEX
TEMPERATURES IN THE EXTENDED. NO MAJOR ADJUSTMENTS MADE.

KIMBLE

.FIRE WEATHER...
ONLY FIRE WEATHER CONCERNS WILL BE LIGHTNING FROM THUNDERSTORMS.
AMPLE MOISTURE AND SIGNIFICANT RAIN CHANCES SHOULD PRECLUDE ANY
SIGNIFICANT FIRE WEATHER SITUATIONS.
