NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

SOUTHWEST TO WEST WINDS ALOFT WERE BRINGING IN DRIER AIR OVER
REGION. IN ADDITION SUBSIDENCE CONDITIONS WERE MOVING INTO TO THE
REGION BEHIND UPPER LEVEL SHORTWAVE...AS INDICATED IN THE WATER
VAPOR LOOP.

RAIN CHANCES QUITE LOW TONIGHT WITH ABOVE CONDITIONS. CAN NOT REALLY
RULE OUT AN ISOLATED SHOWER OR THUNDERSTORM HOWEVER. CAPES WILL
RANGE FROM ZERO OVER WESTERN HALF TO AROUND 1500 J/KG OVER EXTREME
EASTERN SECTIONS. THINKING AT THIS TIME...IS TO HAVE A 10 PERCENT
CHANCE OF STORMS ONLY IN EASTERN ZONES.

BE LIMITED IN SOUTHERN ZONES WITH FRONT COMING IN THE AFTERNOON.
WILL INCLUDE A SLIGHT CHANCE OF THUNDERSTORMS IN THE NORTHWEST HILL

THE AFTERNOON AT TIME OF MAXIMUM HEATING.

THURSDAY EVENING AND FRIDAY....MOIST AIR RETURNS WITH WARM FRONT...
AND WEAK SHORTWAVES...SMALL POPS WARRANTED.

ACROSS THE EASTERN COUNTIES.  ONE OR TWO OF THE STORMS COULD
APPROACH SEVERE LIMITS.  AREAS WEST OF A
