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

Topeka, KS (KTOP), launched 00:00Z, 9.6 hours before the alert went out and 110 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...

CIRCULATION CENTER ASSCD WITH THE REMNANTS OF DOLLY HAS SHIFTED INTO
SERN KS WITH AN ELONGATED SHEAR AXIS EXTENDING NE INTO CENTRAL/NORTH
CENTRAL MISSOURI. LATEST GFS/RUC APPEAR TO HAVE A MUCH BETTER HANDLE
ON THE SITUATION AS THE NAM QPF HAS BEEN MUCH TOO FAR NORTH

A RATHER SHARP H7/H5 DEFORMATION ZONE HAS LIMITED THE NWD EXTENT OF
THE HEAVY PRECIP SHIELD...FM KC AREA ENE TO NR MACON. THIS IS WELL
HANDLE BY THE GFS WITH THE GFS TO SHIFT THIS AXIS SLOWLY SE THROUGH
THE DAY. A VERY IMPRESSIVE H8/H7 THETAE RIDGE WAS POSITION NR THE
DEFORMATION ZONE WITH COPIOUS AMOUNT OF TROPICAL MOISTURE...2-2.5
PRECIPITABLE WATER...RESULTING IN VERY HEAVY RAINFALL AMOUNTS. CLOUD
TOPS HAVE WARMED THE LAST FEW HOURS AS THE LLJ HAS VEERED.
HOWEVER...EXCESSIVE RAINFALL AMOUNTS ARE STILL LIKELY THIS MORNING
BEFORE SYSTEM BEGINS TO WEAKEN AND BEGIN ITS DIURNAL DECREASE IN THE
AFTN.

SINCE RADAR TRENDS VERIFY THE LATEST GFS...HAVE REMOVED THE XTRM NRN
EXTENT OF THE FFA.

OTHERWISE...HAVE CONCERN ABOUT LOW CLOUDS AND FOG TNGT. MORE
CONFIDENT IN AREAS OF FOG AFTER MIDNIGHT IN AREAS WHICH HAVE RECEIVED
THE HEAVY RAIN TODAY.

UPPER RIDGE OF HIGH PRESSURE TO BUILD INTO THE REGION THURSDAY AND
FRIDAY WITH VERY WARM TEMPERATURES RETURNING.
