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

Lincoln, IL (KILX), launched 12:00Z, 11.7 hours before the alert went out and 316 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
NATIONAL WEATHER SERVICE WILMINGTON OH
725 PM EDT TUE JUL 4 2006

.AVIATION /00Z-24Z/...
SCATTERED SHOWERS AND THUNDERSTORMS CONTINUING ACROSS MUCH OF THE FA
THIS EVENING. STORMS ACROSS THE SOUTHERN PORTIONS OF FA HAVE
GENERALLY EXHIBITED A WEAKENING TREND DURING THE PAST COUPLE OF
HOURS...WITH THE MORE ORGANIZED ACTIVITY NOW ACROSS NORTHERN
PORTIONS OF FA...CLOSER TO THE FRONT. THINK WE WILL CONTINUE TO SEE
THIS TRANSITION THROUGH THE REST OF THE EVENING WITH THE FRONTAL
BOUNDARY BECOMING THE MAIN FOCUS FOR ANY PCPN. EXPECT PCPN WITH THE
FRONT TO PUSH SLOWLY SOUTH THROUGH THE OVERNIGHT HOURS SO WILL
GRADUALLY TAPER OFF ANY PCPN IN THE TAFS FROM NORTH TO SOUTH
OVERNIGHT.  WILL ALLOW FOR SOME LINGERING MID VFR CLOUDS LATE
TONIGHT INTO WEDNESDAY MORNING ON BACK SIDE OF FRONT. THEN...BEHIND
THE FRONT DURING THE DAY ON WEDNESDAY...EXPECT MAINLY JUST SOME SCT
CU.

.PREV DISCUSSIONS...

THE FOLLOWING WAS ORIGINALLY ISSUED AT 348 PM EDT TUE JUL 4 2006

SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/...
COLD FRONT NOTED JUST N OF FCST AREA WILL CONTINUE TO MOVE SLOWLY S
TONIGHT. SHOWERS AND THUNDERSTORMS ALONG AND AHEAD OF THE FRONT WILL
PERSIST IN SW-NE ORIENTED BANDS THIS EVENING AND BE ON THE DECREASE
AS MORE STABLE AIR GETS ADVECTED IN ON N WINDS WITH THE PASSAGE OF
THE FRONT TONIGHT.

AREAS ALONG AND S OF OHRIVER COULD SEE ACTIVITY ON WED...ESPECIALLY
IN THE MORNING AS THE FRONT IS EXPECTED TO BE LOCATED ALONG OR JUST
S OF IT. THIS SFC FRONT WILL OUTPACE THE MID LEVEL FORCING OF A H5
L/W WHICH WILL HELP IN KEEPING SOME LEFTOVER ACTIVITY IN THE SE.

SFC HIGH BUILDS FROM NW TO SE ON WED AND WED NIGHT. NW FLOW WITH
SIGNIFICANTLY MORE STABLE AND DRIER AIR WILL ALLOW FOR COOLER
NIGHTTIME TEMPS AND A BREAK IN THE HOT AND HUMID CONDITIONS TOMORROW
FOR MUCH OF THE REGION.

FRANKS

THE FOLLOWING WAS ORIGINALLY ISSUED AT 348 PM EDT TUE JUL 4 2006

LONG TERM /THURSDAY THROUGH TUESDAY/...
MAJORITY OF THE EXTENDED PERIOD WILL BE DRY AS SURFACE HIGH PRESSURE
WILL BE THE DOMINANT FEATURE.  PERIOD WILL BEGIN WITH SLIGHTLY BELOW
NORMAL TEMPERATURES FOR THE END OF THE WORK WEEK AS REGION WILL BE
UNDER THE INFLUENCE OF MID LEVEL TROUGH.  SURFACE HIGH PRESSURE WILL
SLOWLY DRIFT EAST AND MID LEVEL RIDGE WILL BUILD IN FOR THE UPCOMING
WEEKEND.  THIS WILL ALLOW FOR AN INCREASE IN TEMPERATURES AND
HUMIDITY WITH RETURN FLOW.  NEXT CHANCE FOR PRECIPITATION LOOKS TO
BE MONDAY AND TUESDAY AS A COLD FRONT MOVES ACROSS THE REGION.  HAVE
JUST INSERTED A SLIGHT CHANCE FOR NOW.  RLG &&
