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

Davenport, (KDVN), launched 12:00Z, 8.4 hours before the alert went out and 177 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.

THE WX PATTERN WILL BE DOMINATED BY AN UPPER LEVEL TROUGH FOR THE
FIRST PART OF THE WEEK. H5 TEMPS WILL BE ON THE COOL SIDE...MAINLY
IN THE MINUS 14-16C RANGE. DAYTIME HEATING WILL HELP TO GENERATE
THE SCT SHRA/TSRA. UPPER LEVEL DCVA WILL BE PLAYING A ROLE AS WELL FROM
TIME TO TIME DUE TO SPOKES OF VORT AND PROX OF UPPER LEVEL CIRC.

FOR TODAY THE WATER VAPOR/RUC ANIMATION SHOWS A VORT CENTER WEST
OF KGRB WITH TAIL OF SAID VORT PRODUCING THE SCT SHRA ACRS ERN
CWA. ANOTHER VORT MAX INTO WRN IA. THESE 2 COMBINE INTO ONE UPPER
LOW AND EVOLVE AN UPPER LOW CENTER ACRS ERN IA BY 00Z MON. THIS
PLACES THE WRN CWA WITHIN THE BEST ZONE OF DCVA...ALTHO ENTIRE CWA
IS WITHIN THE GRASP OF TROUGHINESS ALOFT AND THE ASSOC COOL POOL.
LI/S BECOME NEGATIVE AS WELL. CAPES AE QUITE SKINNY AND JUST A FEW
HUNDRED. WILL HAVE HIGHEST POPS IN WRN CWA.

MODELS SHOW THE MAIN UPR LOW CENTER DRIFTING FURTHER SE TNGT
ALTHO CWA REAMINS IN UPPER TROF AXIS. IN FACT GFS INDICATES A 23
UNIT VORT CENTER WRAPPING NWD INTO SRN WI TNGT. WILL HAVE HIGHEST
POPS IN SRN CWA.
