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

Green Bay/Straub, WI (KGRB), launched 12:00Z, 10.7 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.

.DISCUSSION...FCST FOCUS ON UPR LOW AND PCPN LOCATION AND AMOUNTS

ONCE AGAIN A BUSY AFTERNOON IN CWA AS INVERTED SFC LOW POKING INTO
SRN CWA AND ASSOCIATED LOW-LVL MOISTURE CONVERGENCE COMBINING WITH
CVA FROM APPROACHING SHRT WV TO TRIGGER CONVECTION. STORMS ALIGNING
ALONG AXIS OF BEST 1000-850MB THETA-E CONVERGENCE. WEAK SHEAR...
WINDS BLO 20K FT ARE UNDER 20 KTS...ARE PREVENTING MORE WIDESPREAD
OR SUSTAINED ORGANIZATION TO STORMS...BUT INDIVIDUAL CELLS STILL
ABLE TO PULSE UP AND PRODUCE SVR HAIL AND GUSTY WINDS.

HEAVY RAINS WITH SLOW MOVING STORMS ON NORTHERN PERIPHERY OF

UPPER LEVEL TROUGH WILL BE THE MAIN WX FEATURE FOR THE FIRST PART OF
THE WEEK. COOL 500 MB TEMPS IN THE -14 TO -16C RANGE WILL PROVIDE
STEEP MID LVL LAPSE RATES...DAYTIME HEATING AND UPPER LEVEL DCVA
FROM VARIOUS VORTICITY MAXIMA ROTATING AROUND MAIN CIRCULATION
CENTER WILL BRING SCT SHRA THRU THE DAY MONDAY.

MODELS AGREE THAT SECOND TROUGH WILL DROP INTO WRN GRT LKS
