What was reported inside it

Time	Report	Where	Remark
Jul 27, 4:23 PM EDT	HEAVY RAIN 5.25	Elizabethtown, KY	A TRAINED SPOTTER NEAR MILE MARKER 94 OFF OF 1-65 REPORTED 5.25 INCHES OF RAIN HAD FALLEN OVER THE PAST 3 HOURS.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Nashville Metro, TN (KBNA), launched 12:00Z, 8.1 hours before the alert went out and 198 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.

What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Louisville, KY wrote its last area forecast discussion before this flash flood warning went out at Jul 27, 3:08 PM EDT, 55 minutes earlier.

Area forecast discussion, Jul 27, 3:08 PM EDT, 55 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
308 PM EDT TUE JUL 27 2010

.SHORT TERM (TONIGHT AND WEDNESDAY)...

A VERY MOIST (PW VALUES AROUND 2.2 INCHES) SOUTHWEST FLOW WILL
CONTINUE ACROSS THE LOWER OHIO VALLEY FOR THIS FORECAST PERIOD. SO
IT WILL NOT TAKE MUCH TO SET OFF THUNDERSTORMS WITH THE LATEST ROUND
OCCURING AT 19Z ACROSS CENTRAL KENTUCKY AND EXTENDING NORTHWEST INTO
SOUTHWEST INDIANA. THIS IS BASICALLY ALONG A WEAK AND DISSIPATING
DEW POINT BOUNDARY. THE LATEST SATELLITE PICTURES ALSO INDICATE
COOLING TOPS SO WE WILL NEED TO MENTION A PRE-FIRST PERIOD IN THE
FORECAST WITH STORMS LIKELY ACROSS MUCH OF THE EASTERN FORECAST
AREA.

I DO THINK THERE WILL BE A LULL IN PRECIPITATION OVERNIGHT WITH THE
LOSS OF HEATING. HOWEVER IF BOUNDARIES REMAIN FROM THE LATE
AFTERNOON STORMS OVERNIGHT THUNDERSTORMS WILL BE POSSIBLE. BUT FOR
NOW WE WILL DROP POPS OVERNIGHT INTO THE SLIGHT CHANCE CATEGORY.

WE WILL MENTION HIGH CHANCE POPS WEDNESDAY AFTERNOON WITH THE SAME
AIRMASS IN PLACE AND HEAVY RAIN AGAIN THE MAIN CONCERN.

IN THIS WARM AND MOIST AIRMASS TEMPERATURES TONIGHT WILL ONLY FALL
INTO THE LOW AND MID 70S AND WARM AGAIN INTO THE UPPER 80S AND LOWER
90S.

.LONG TERM (WEDNESDAY NIGHT - TUESDAY)...

THE FASTER GFS SEEMS TO BE VERIFYING BETTER THAN THE SLOWER
EURO/CANADIAN MODELS OVER THE PAST FEW DAYS SO WILL TREND CURRENT
FORECAST TOWARDS A FASTER GFS/GFS ENSEMBLE SOLUTION.

WEDNESDAY NIGHT-SATURDAY NIGHT...

SHORT-TERM MODELS AGREE THAT A FRONT APPROACHING FROM THE NW WILL
LIKELY DRIFT TO OR JUST SOUTH OF THE OHIO RIVER BY EARLY THURSDAY
MORNING. FOR WEDNESDAY NIGHT...MOST OF THE ACTIVITY SHOULD
CONCENTRATE ALONG THE FRONT SO ANY DIURNAL ACTIVITY WILL LIKELY
WEAKEN OR DISSIPATE...AND FOCUS NORTH TOWARDS THURSDAY MORNING. THE
FRONT WILL PUSH SE OF THE CWA BY THURSDAY EVENING...SO TREND THE
POPS SEWD THURSDAY DURING THE DAY WITH THE BLUEGRASS REGION HAVING
THE HIGHEST POPS. BECAUSE OF THIS...TRENDED BACK ON HIGHS THRS.

LOWER DEWPOINTS WILL FILTER IN FOR A SHORT-TIME ON FRIDAY LEAVING US
WITH PLEASANT DRY DAY WITH HIGHS IN THE MID 80S NE TO THE VERY LOW
90S SOUTH. BY SATURDAY THOUGH WITH NW FLOW ALOFT...ANOTHER
DISTURBANCE QUICKLY PUSHES IN AND AFFECTS US LATE FRIDAY NIGHT
ACROSS THE NW BUT MOSTLY ON SATURDAY. AGAIN...THIS QUICKLY MOVES
SOUTHEAST OF THE CWA SATURDAY NIGHT...BUT KEPT IN SLIGHT CHC POPS
OVER THE SE SAT NIGHT.

GIVEN A BIT OF ADDED DYNAMICS WITH THE SYSTEMS THURSDAY AND
SATURDAY...A FEW MORE ORGANIZED CELLS WILL BE POSSIBLE WITH STRONG
GUSTY WINDS/ISOLATED DMG WINDS POSSIBLE WITH THE VERY STRONGEST
CELLS. MOST IF NOT ALL WILL REMAIN BELOW SEVERE LIMITS.

SUNDAY-TUESDAY...

FOR THIS PERIOD...THE RIDGE OVER THE SRN PLAINS WILL SCOOT EASTWARD
DURING THIS PERIOD. ALTHOUGH HEIGHT VALUES ARE DISPLACED AND
DIFFERENT BETWEEN THE EURO AND GFS...BOTH MODELS HAVE A DISTURBANCE
UNDER THE RING OF FIRE APPROACH US TUESDAY FROM THE NORTHWEST. HAVE
INSERTED POPS TUESDAY OVER THE NW AND TUESDAY NIGHT
EVERYWHERE...SMALL POPS THIS FAR OUT. ALSO GIVEN THE HEIGHTS
INCREASING TOWARDS TUESDAY...TRENDED TOWARDS THE HOT MEX BUT NOT
NEARLY AS HOT SINCE EVERY TIME THAT MOS GUIDANCE HAS SHOWN 98
DEGREES FOR SDF FOR EXAMPLE...WE WERE ABOUT 2 DEGREES OR MORE
COOLER.

&&

.AVIATION (18Z TAF ISSUANCE)...

A VERY MOIST SOUTHWEST FLOW WILL KEEP THUNDERSTORMS SCATTERED ACROSS
CENTRAL KENTUCKY THIS AFTERNOON AND EVENING. THE LATEST SHORT RANGE
MODELS KEEP MOST OF THE PRECIPITATION SOUTH OF SDF BUT NOT LEX OR
BWG. SO BASED ON CURRENT SATELLITE AND RADAR TRENDS WE WILL JUST
MENTION VCTS AT THE SDF AND BWG TAF LOCATIONS THIS AFTERNOON BUT TRY
TO TIME CURRENT CONVECTION OVER CENTRAL KENTUCKY INTO LEX LATE THIS
AFTERNOON. BECAUSE OF THE EARLIER AND EXPECTED PRECIPITATION AT LEX
WE WILL ALSO DROP THEM INTO THE IFR RANGE FOR VSBYS OVERNIGHT.

SCATTERED THUNDERSTORMS ARE EXPECTED AGAIN WEDNESDAY.
