The radar

The Cincinnati radar (KILN), 125 km from the middle of the area, began a volume at 00:16 UTC, the scan nearest the moment this went out.

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

Cncnati-Daytn, OH (KILN), launched 00:00Z, 0.3 hours before the alert went out and 123 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, Jul 14, 7:41 PM EDT, 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
741 PM EDT MON JUL 14 2014

.SYNOPSIS...
A COLD FRONT WILL CROSS THE REGION TONIGHT. SHOWERS AND
THUNDERSTORMS WILL BE LIKELY AHEAD OF THIS FRONT THIS EVENING INTO
EARLY MORNING TUESDAY. AN UNSEASONABLY COOL AIRMASS WILL MOVE INTO
THE REGION BEHIND THIS FRONT THROUGH MID WEEK.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
OUR FORECAST AREA RESIDES BETWEEN TWO COLD FRONTS THIS AFTERNOON WITH
CONVECTION MAINLY CONFINED TO OUR SOUTHEAST AND WEST. ORGANIZED
CONVECTION TO OUR WEST IS ASSOCIATED WITH THE LEADING EDGE OF AN
UNSEASONABLY COOL AIRMASS THAT IS SURGING SOUTHEASTWARD TOWARD OUR
REGION. THIS UPSTREAM CONVECTION IS BEING AIDED BY 45 KT OF 0-6 KM
SHEAR AND 1500 J/KG OF M/L CAPE ACROSS ILLINOIS AND WESTERN INDIANA.
LOW LEVEL MOISTURE IS TRYING TO INCREASE AHEAD OF THIS LINE OF
CONVECTION TO OUR WEST. HOWEVER...A SHORTWAVE THAT PASSED ACROSS THE
REGION EARLIER THIS AFTERNOON CONTAINED DRY AIR IN THE MID LEVELS.
THERE APPEARS TO NOW BE A POOL OF STABLE AIR BETWEEN THIS LINE OF
CONVECTION AND OUR AREA...WITH THE RAP SPC ANALYSIS INDICATING ONLY
500 J/KG OF M/L CAPE AT BEST ACROSS EASTERN INDIANA.
THEREFORE...ALTHOUGH THE NEAR SURFACE DEWPOINTS ARE ON THE RISE DUE
TO WARM ADVECTION AHEAD OF THE FRONT...THERE IS SOME DOUBT THAT THAT
MID LEVELS WILL SUFFICIENTLY MOISTEN AHEAD OF THIS LINE BEFORE IT
CROSSES EASTERN INDIANA INTO OUR AREA LATE THIS AFTERNOON AND THIS
EVENING. CURRENT THINKING FROM THIS FORECASTER IS THAT CONVECTION
WILL BE ON A WEAKENING TREND AS IT ENTERS OUR AREA...WITH SUFFICIENT
FORCING TO PRODUCE MAINLY SUB SEVERE SHOWERS AND THUNDERSTORMS IN
OUR AREA AS THE FRONT CROSSES THE REGION LATER THIS EVENING. THE
BEST CHANCE FOR ANY SEVERE CELLS WILL BE ACROSS OUR WEST...WHERE
CONVECTION WILL ARRIVE DURING THE DAYLIGHT HOURS...WITH UNLIKELY
SEVERE WEATHER ACROSS THE EASTERN PORTIONS OF THE ILN CWA.

LINGERING PRECIPITATION WILL EXIT TO THE EAST TUESDAY MORNING AS THE
COLD FRONT PUSHES THROUGH. TEMPERATURES BEHIND THE FRONT TONIGHT
WILL DROP INTO THE 60S. TEMPERATURES ACROSS THE NORTHWESTERN ZONES
WILL LIKELY DROP INTO THE 50S BEFORE SUNRISE...DEEPER INTO THE
COLDER AIRMASS. THE SOUTHEASTERN ZONES MAY ONLY DROP INTO THE UPPER
60S AS THE FRONT MAY BE JUST CROSSING THOSE ZONES AROUND SUNRISE.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
NORTHWESTERLY FLOW WILL BRING IN A CANADIAN AIRMASS THROUGH THE
DAY TUESDAY. THIS COLD ADVECTION WILL PROBABLY KEEP TEMPERATURES
FROM RISING OUT OF THE LOWER 70S DURING THE DAY TUESDAY...WHICH
COULD RESULT IN RECORD LOW MAXIMUMS FOR THE DATE.

THE COOLER AND DRIER AIRMASS WILL RESULT IN LOW TEMPERATURES
DROPPING INTO THE LOWER 50S TUESDAY NIGHT.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
AN UNSEASONABLY COOL SURFACE HIGH PRESSURE SYSTEM WILL SLIDE EAST
ACROSS THE AREA WEDNESDAY INTO THURSDAY. WITH SOME DAYTIME HEATING
ON WEDNESDAY AND LAGGING COLD AIR ALOFT...ENOUGH INSTABILITY MAY
DEVELOP THROUGH THE AFTERNOON TO SUPPORT A FEW SHOWERS. WEDNESDAY
WILL LIKELY BE THE COOLEST OVERALL DAY OF THE UPCOMING WEEK WITH
HIGHS IN THE LOW TO MID 70S ACROSS OUR AREA.

AS THE HIGH PUSHES OFF TO THE EAST AND THE AIRMASS BEGINS TO
MODIFY...EXPECT A GRADUAL WARM UP THROUGH THE END OF THE WEEK WITH
HIGHS EVENTUALLY PUSHING UP TO AROUND 80 DEGREES BY SATURDAY. SOME
UNCERTAINTY STILL EXISTS BETWEEN THE 12Z GFS AND 12Z ECMWF IN REGARD
TO THE SOUTHERN STREAM SYSTEM LIFTING OUT OF THE GULF STATES FRIDAY
INTO SATURDAY. IT DOES LOOK LIKE THE BEST FORCING WITH THIS WILL
GENERALLY REMAIN TO OUR SOUTH AND SOUTHEAST. WILL CONTINUE WITH
LOWER END POPS WITH THIS...ESPECIALLY ACROSS SOUTHEAST PORTIONS OF
OUR FA. THE GFS TRIES TO KEEP A MORE AMPLIFIED PATTERN IN PLACE
ACROSS THE REGION INTO EARLY NEXT WEEK WHILE THE ECMWF TRANSITIONS
TO SOMEWHAT MORE OF A ZONAL FLOW PATTERN. WILL MAINTAIN A DRY
FORECAST AT THIS TIME...BUT IF THE MORE AMPLIFIED GFS ENDS UP BEING
RIGHT...WE WOULD HAVE A BETTER CHANCE OF PCPN TOWARD THE END OF THE
PERIOD. TEMPERATURES WILL CONTINUE TO MODIFY SUNDAY INTO MONDAY WITH
HIGHS IN THE LOW TO MID 80S BOTH DAYS.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
LINE OF THUNDERSTORMS DEVELOPED IN MODERATELY UNSTBL AIRMASS AHEAD
OF AN APPROACHING COLD FRONT FROM THE WEST. THESE STORMS WILL PRODUCE
WIND GUSTS AS HIGH AS 40 KTS FROM THE NW IN NEXT COUPLE OF HOURS. HEAVY
RAIN WILL RESULT IN MVFR CIGS AND BRIEF IFR VSBYS. THESE STORMS
ARE EXPECTED TO WEAKEN AS THEY PUSH EAST ACRS OHIO.

ONCE THE LINE OF CONVECTION MOVES THRU...LIGHT SHOWERS MAY LINGER
FOR A FEW HOURS FROM A VFR CLOUD DECK. WITH WET GROUND SOME FOG
WILL BE POSSIBLE AT KLUK OVERNIGHT BUT WITH DRIER AIR ADVECTING IN
WILL LIMIT ANY MENTION TO MVFR RESTRICTION. IN THE WAKE OF THE FRONT
EXPECT VFR CIGS AROUND 4000 FEET ON TUESDAY. NORTHWEST WINDS WILL
GUST UP TO 22 KTS.

OUTLOOK...NO SIGNIFICANT WEATHER IS EXPECTED.
