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

Nashville Metro, TN (KBNA), launched 12:00Z, 11.6 hours before the alert went out and 220 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 LOUISVILLE KY
711 PM EDT MON SEP 21 2009

.UPDATED FOR 00Z TAFS...

.SHORT TERM (TONIGHT AND TUESDAY)...

THE FORECAST SETUP REMAINS SIMILAR TONIGHT AND THROUGH MOST OF
TUESDAY AS IT HAS BEEN THE LAST DAY OR TWO. A MID LEVEL TROUGH
CONTINUES TO SIT OVER THE UPPER MIDWEST INTO THE LOWER MISSISSIPPI
VALLEY. WAVES OF ENERGY WILL CONTINUE TO ROTATE THROUGH THE FLOW AND
WITH SOUTHERLY FLOW GULF MOISTURE WILL CONTINUE TO STREAM INTO THE
REGION. THE TROUGH HAS PROGRESSED EASTWARD SOMEWHAT FROM YESTERDAY
SO THE BULK OF PRECIPITATION TODAY HAS STAYED MAINLY ACROSS EASTERN
PORTIONS OF THE FORECAST AREA KEEPING SOUTHERN INDIANA AND WEST
CENTRAL KY MAINLY DRY. SHOWERS WERE INCREASING ACROSS THE REGION
THIS AFTERNOON HOWEVER IN RESPONSE TO SOME INCREASING INSTABILITY
AND A STRENGTHENING UPPER LEVEL JET OVER THE REGION.

EXPECT THAT AT LEAST SCATTERED SHOWERS WILL STICK AROUND OVERNIGHT
GIVEN THE MOIST AIRMASS WITH OHX MORNING SOUNDING SHOWING PWAT
VALUES OF AROUND 1.80 INCHES...HOWEVER SOME DRIER AIR AND SUBSIDENCE
WILL NOSE INTO CENTRAL KENTUCKY TONIGHT..AS NOTED BY WV IMAGERY...AS
THIS SYSTEM BEGINS TO LIFT OUT OF THE REGION AN UPPER LEVEL RIDGE
BEGINS TO BUILD WESTWARD ACROSS THE SOUTHEAST STATES AND INTO THE
GREAT LAKES BY TUESDAY MORNING AND THROUGH THE AFTERNOON BRING A
BREAK IN PRECIPITATION TOWARD TUESDAY NIGHT AHEAD OF THE CLOSED LOW
SYSTEM OVER THE CENTRAL PLAINS. THEREFORE...LOWERED POPS...KEEPING
ONLY SCATTERED SHOWERS AND ISOLATED THUNDER IN THE FORECAST
THROUGH TUESDAY AFTERNOON. AS WITH THE LAST FEW DAYS SOME SHOWERS
WILL CAUSE LOCALLY HEAVY RAINFALL AND AREAS EAST OF INTERSTATE 65
WILL BE MONITORED CLOSELY TONIGHT FOR ANY FLOODING POTENTIAL.

OVERNIGHT LOWS AGAIN BE WARM WITH MID TO UPPER 60S EXPECTED. HIGHS
TOMORROW WILL RANGE FROM THE MID 70S TO LOW 80S.

.LONG TERM (TUESDAY NIGHT THROUGH MONDAY)...

TUESDAY NIGHT THROUGH THURSDAY...

THE GFS HAS COME MORE IN LINE WITH THE ECMWF FOR THIS FORECAST
PERIOD WITH A DEEP UPPER LEVEL CUTOFF LOW OVER THE CENTRAL PLAINS.
THIS COMBINED WITH A RIDGE OFF THE EAST COAST WILL CONTINUE TO PUMP
WARM AND MOIST AIR INTO THE LOWER OHIO VALLEY. A NUMBER OF WEAK
FRONTS WILL MOVE FROM THE MID MISSISSIPPI VALLEY INTO THE LOWER OHIO
VALLEY AND DISSIPATE. WE WILL KEEP PRECIPITATION IN ALL THE FORECAST
PERIODS BUT IT LOOS AS IF THE BEST CHANCE FOR RAIN WILL BE WEDNESDAY
AND THURSDAY AFTERNOON AND EVENING. HEAVY RAIN WILL AGAIN BE THE
MAIN CONCERN AS BUFKIT FORECAST SOUNDINGS INDICATE PERCEPTIBLE WATER
VALUES ABOVE 1.75 INCHES AND EVEN OVER 2 INCHES THURSDAY AFTERNOON.

UNDER THE MOIST AIR MASS AND CLOUD COVER WE WILL SEE TEMPERATURES
FROM THE MID AND UPPER 60S IN THE MORNING TO AROUND 80 DEGREES
DURING THE AFTERNOON.

FRIDAY THROUGH MONDAY...

DURING THE LAST HALF OF THE WEEK THE AFOREMENTIONED CLOSED LOW WILL
BEGIN TO SHIFT EAST AND OPEN UP. IN THE MEANTIME A NORTHEAST TROUGH
WILL SHARPEN UP. SURFACE LOW PRESSURE WILL MOVE ACROSS THE EASTERN
GREAT LAKES AND INTO NEW ENGLAND. THE RESULTING COOL FRONT WILL DROP
INTO THE REGION AND STALL. THIS WILL CREATE AN ADDITIONAL BOUNDARY
FOR STORM DEVELOPMENT FRIDAY AND SATURDAY. AN APPROACHING STRONG
COLD FRONT WILL KEEP THE POSSIBILITY OF STORMS OVER THE REGION
SUNDAY AND EARLY MONDAY. SO AGAIN WILL WILL CONTINUE TO MENTION POPS
IN ALL PERIODS OF THE FORECAST UNTIL MONDAY AFTERNOON.

TEMPERATURES UPPER 70S AND LOWER 80S WILL BEGIN TO COOL OVER THE
WEEKEND WITH HIGHS ONLY IN THE LOW AND MID 70S BY MONDAY.

&&

.AVIATION (22/00Z TAFS)...

SCATTERED SHRA/TSRA WILL AGAIN RULE THE FIRST 12 HOURS OF THIS TAF
PERIOD. THERE ARE MORE BREAKS IN THE CLOUDS PRESENT...AND SOME
CLEARING OFF TO THE WEST...MORE SO THAN YESTERDAY. THIS COULD ALLOW
FOR FOG TO DEVELOP TOWARDS MORNING...THOUGH BUFKIT SOUNDINGS
INDICATE THAT TERMINALS WILL BE SOCKED IN WITH STRATUS AS OPPOSED TO
FOG...MUCH LIKE THIS MORNING. IF ANY TERMINAL SEES FOG INSTEAD OF
STRATUS IT WOULD BE BWG TOWARDS 12Z SINCE THEY ARE CLOSER TO THE
CLEARING WEST OF OUR REGION. OTHERWISE BKN-OVC CIGS...SOMETIMES MVFR
WILL DOMINATE LEX...THOUGH IT WILL VARY FROM MVFR-VFR CIGS AT SDF.
BWG WILL SEE SCT CLOUDS THROUGH 12Z. ANY SHRA/TSRA WILL MAINLY
AFFECT LEX THROUGH 12Z TUESDAY (THOUGH THROUGH 01Z BWG)...SO IFR
VSBYS WILL BE POSSIBLE WITH THE HEAVIER CELLS.

AFTER ROUGHLY 14Z TUESDAY...MODELS INDICATE ANOTHER SHORTWAVE
HELPING TO FORCE MORE SHRA/TSRA. TIME-HEIGHT CROSS SECTIONS FOR BWG
SHOW GOOD LIFT AND AMPLE CLOUDS/PRECIP FROM 15-20Z...SO BETTER
COVERAGE OF SHRA/TSRA EXPECTED TOMORROW ACROSS ALL TERMINALS. ANY
SHOWERS AND STORMS AGAIN TOMORROW WILL CAUSE IFR VSBYS AND MVFR CIGS
ON AVERAGE.
