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 00:00Z, 10.5 hours before the alert went out and 164 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.

Area forecast discussion, Jun 24, 3:03 PM CDT, 14 hours 26 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
203 PM MDT SAT JUN 24 2006

.SHORT TERM... (TONIGHT - TUESDAY)
FORECAST PROBLEM WILL BE CONVECTION ASSOCIATED WITH WEAK COLD FRONT
WHICH WILL PUSH THROUGH TONIGHT AND SUNDAY. BEST UPPER SUPPORT FOR
THE FRONT WILL BE OVER IOWA...BUT APPEARS CWA WILL GET BRUSHED BY
SOME PVA AS TROUGH AXIS APPROACHES/WEAK 500MB HEIGHT FALLS FORECAST
BETWEEN 06Z TONIGHT AND 18Z ON SUNDAY. MODELS BRING IN SOME LIGHT
QPF AND INCREASE 700-500MB RH DURING THAT TIME FRAME. RIGHT REAR
QUADRANT OF 250MB JET ALSO OVER THE AREA BETWEEN 12Z-18Z SUNDAY
MORNING. BEST CHANCES APPEAR TO BE IN COLORADO ZONES AS CONVECTION
MIGRATES SOUTH SOUTHEASTWARD FROM NORTHERN COLORADO/CHEYENNE RIDGE
OVERNIGHT AND INTO EARLY SUNDAY MORNING. PRECIPITATION WILL END FROM
NORTH TO SOUTH SUNDAY AFTERNOON AS TROUGH AXIS CONTINUES SOUTH AND
500MB HEIGHTS BEGIN TO RISE.

NEARLY MERIDIONAL UPPER FLOW WILL SET UP ON MONDAY...WITH HINTS OF A
SHORTWAVE RIDGE. PROFILES QUITE DRY THROUGH THE COLUMN...WILL KEEP
IT DRY. CONVECTION DURING THE DAY ON TUESDAY APPEARS TO BE DIURNALLY
DRIVEN AND RESTRICTED TO EASTERN COLORADO. WEAK 0-6KM MEAN WINDS
SUGGESTS THEY WILL NOT REACH KANSAS BEFORE DISSIPATING AFTER DARK.
WILL ALSO NEED TO WATCH FRONTAL BOUNDARY APPROACHING FROM NEBRASKA
ON TUESDAY. OPERATIONAL GFS CONSIDERABLY FASTER THAN NAM/WRF.
CONSIDERING STRENGTH OF UPPER RIDGE TO THE SOUTHWEST...PREFER SLOWER
TIMING. THIS WOULD SUPPORT SLIGHT CHANCE POPS TUESDAY NIGHT.

.LONG TERM... (WEDNESDAY - SATURDAY)
UPPER RIDGE WILL GRADUALLY BUILD NORTH AND EASTWARD THIS PERIOD FROM
THE DESERT SOUTHWEST...AND BE CENTERED NEAR THE CENTRAL ROCKIES BY
THE END OF THE WEEK. ECMWF A LITTLE FASTER WITH THIS THAN THE
OPERATIONAL GFS...BUT BOTH MODELS SHOWING THE SAME TREND. THE
TEMPERATURE FORECAST WILL THEREFORE REFLECT A GRADUAL WARMING
TREND...ENDING UP ABOVE NORMAL AT THE END OF THE PERIOD. AS FOR
PRECIPITATION...UNTIL THE RIDGE AXIS GETS CLOSER THE CWA WILL
CONTINUE TO BE OPEN TO SHORTWAVES COMING THROUGH IN THE NORTHWEST
FLOW ALOFT...EJECTING FROM A LARGE UPPER LOW NEAR THE GREAT LAKES.
COLD FRONT COMING DOWN THE PLAINS SHOULD REINFORCE UPSLOPE FLOW
EARLY IN THE EXTENDED PERIOD...BUT THEN LOW LEVEL FLOW WILL
GRADUALLY TRANSITION TO DOWNSLOPE BY LATE IN THE PERIOD AS UPPER
RIDGE BUILDS. SO WILL HAVE SOME SLIGHT/LOW CHANCE POPS EARLY...THEN
ONLY SLIGHT CHANCES IN COLORADO LATE AS WEAK 0-6KM MEAN WINDS UNDER
THE RIDGE SHOULD LIMIT CONVECTION TO DIURNAL/HIGH TERRAIN TYPE STUFF.
