What was reported inside it

Time	Report	Where	Remark

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 severe thunderstorm 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, 5.0 hours before the alert went out and 151 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, Aug 13, 11:02 PM EDT, 1 hour 55 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
1102 PM EDT SAT AUG 13 2011

...FORECAST UPDATE...

ANOTHER WILD WEATHER NIGHT HERE IN THE OHIO VALLEY WITH SEVERE
STORMS HITTING MUCH OF NORTH-CENTRAL KENTUCKY AND PORTIONS OF
SOUTH-CENTRAL INDIANA.  WORST HIT AREAS APPEAR TO BE ALONG THE AND
GENERALLY NORTH OF THE I-64 CORRIDOR FROM SOUTHERN INDIANA EAST INTO
THE BLUEGRASS REGION OF EASTERN KENTUCKY.  HARD HIT AREAS INCLUDE
LOUISVILLE/LEXINGTON METRO AREAS...FRANKFORT AND SCOTT COUNTY KY.
THUNDERSTORM COMPLEX THAT CONTAINED ALL THE WILD WEATHER CONTINUES
TO MOVE EAST INTO THE EASTERN KENTUCKY COALFIELDS.  ADDITIONAL
CONVECTION IS OCCURING UPSTREAM OVER CENTRAL INDIANA ALONG THE
ACTUAL COLD FRONT.

LATEST SUITE OF HIGH RESOLUTION MODEL GUIDANCE SHOWS THIS BOUNDARY
PASSING THROUGH THE REGION LATE TONIGHT.  SHOWERS AND STORMS WILL
CONTINUE ACROSS THE REGION...WITH THE MOST LIKELY AREA TO SEE
RAINFALL BEING SOUTHERN INDIANA AND THE NORTHERN PORTIONS OF
KENTUCKY.  FOR THAT REASON HAVE LEFT HIGH CHANCE POPS IN THE
FORECAST FOR THE OVERNIGHT PERIOD.  THOUGH..MOST OF THE CONVECTION
SHOULD START TO WANE DURING THE WEE HOURS AS UPPER LEVEL FORCING/JET
DYNAMICS LIFT AWAY FROM THE REGION AND WE START TO SEE A STABILIZING
ATMOSPHERE.

.SHORT TERM (TONIGHT AND SUNDAY)...

SCATTERED THUNDERSTORMS HAVE DEVELOPED OVER SOUTHEAST ILLINOIS THIS
AFTERNOON AND WILL HEAD EAST ACROSS THE WABASH RIVER INTO SOUTHERN
INDIANA. ENOUGH INSTABILITY STILL AROUND FOR SCATTERED STORMS TO POP
IN THE LMK CWFA LATE THIS AFTERNOON INTO THIS EVENING SO WILL
CONTINUE WITH SCT POPS IN THE GRIDS. A FEW OF THE STORMS COULD
BECOME STRONG TO SEVERE WITH GUSTY WINDS...LOCALLY HEAVY RAIN...AND
POSSIBLY SOME SMALL HAIL THOUGH BETTER CHANCES OF SEVERE WILL BE TO
OUR NORTH WHERE INSTABILITY IS GREATER.

SURFACE FRONT STILL ON TRACK TO PASS THROUGH THIS EVENING BUT THE
UPPER TROF AXIS WILL WAIT UNTIL SUNDAY AFTERNOON. SCATTERED SHOWERS
AND A FEW THUNDERSTORMS WILL CONTINUE TO BE POSSIBLE AS A RESULT
INTO SUNDAY MORNING.

LOWS TONIGHT WILL DIP INTO THE MID AND UPPER 60S...WITH HIGHS
TOMORROW IN THE LOWER TO MIDDLE 80S.

.LONG TERM (SUNDAY NIGHT - SATURDAY)...

THE UPPER AIR PATTERN IS EXPECTED TO AMPLIFY EARLY NEXT WEEK. BY
LATE SUNDAY...500MB TROUGHING IS EXPECTED TO MOVE ONSHORE OVER THE
PACIFIC NORTHWEST. DOWNSTREAM OF A BUILDING RIDGE ACROSS THE HIGH
PLAINS...AN UNSEASONABLY DEEP TROUGH WILL SLOWLY MOVE EAST ACROSS
THE SOUTHERN APPALACHIANS. ON MONDAY...LOW PRESSURE WILL MOVE OFF
THE MID ATLANTIC COAST AHEAD OF THIS APPALACHIAN 500MB TROUGH. HIGH
PRESSURE OF CANADIAN ORIGIN WILL BUILD SOUTH ACROSS THE UPPER
MIDWEST MONDAY. BY WEDNESDAY...THIS HIGH PRESSURE IS EXPECTED TO
SLOWLY MOVE EAST OVER OHIO.

WITH NORTHERLY FLOW BOTH AT THE SURFACE AND ALOFT...VERY PLEASANT
MID-AUGUST WEATHER IS EXPECTED MONDAY THROUGH WEDNESDAY WITH LOW
DEWPOINTS AND TEMPERATURES THAT WILL SLOWLY MODERATE FROM THE LOWER
80S MONDAY TO THE UPPER 80S BY WEDNESDAY. DEWPOINTS MAY FALL INTO THE
UPPER 50S BY MONDAY. THIS WILL BRING SEVERAL COMFORTABLE NIGHTS IN A
ROW THROUGH EARLY THURSDAY. ANY RESIDUAL CLOUDINESS ASSOCIATED WITH
TROUGHING TO THE EAST WILL CLEAR BY EARLY MONDAY. MOSTLY CLEAR SKIES
ARE THEN EXPECTED THROUGH WEDNESDAY.

BOTH THE ECMWF AND THE GFS FORECAST A SOMEWHAT COMPACT 500MB LOW TO
CROSS SOUTHERN CANADA NEAR MINNESOTA LATE WEDNESDAY. ALTHOUGH THE
STRONGEST FORCING AND DYNAMICS ARE EXPECTED TO STAY NORTH ACROSS THE
GREAT LAKES...THIS FEATURE WILL BRING A SLOW MOVING FRONT TOWARDS
THE OHIO RIVER BY THURSDAY. MOISTURE RETURN WILL NOT BE TOO ROBUST
UNTIL JUST AHEAD OF THE BOUNDARY. WILL CONTINUE WITH ONGOING
FORECAST OF SCATTERED SHOWERS AND THUNDERSTORMS THURSDAY. AFTER THIS
FRONT PASSES...EXPECT FRIDAY AND SATURDAY TO STAY DRY WITH
SEASONABLE TEMPERATURES

&&

.AVIATION (00Z TAF ISSUANCE)...

STORMS FROM EARLIER THIS EVENING HAVE CLEARED SDF AND WILL BE BEYOND
LEX BY 01Z. BWG SHOULD REMAIN UNAFFECTED. NEW LINE OF STORMS THAT
HAS BLOWN UP OVER ILLINOIS WILL HEAD TO THE SOUTHEAST. CURRENT
INDICATIONS ARE THAT THIS LINE WILL LOSE MUCH OF ITS PUNCH BY THE
TIME IT REACHES THE OHIO VALLEY. WILL TIME IT IN TO LOUISVILLE AND
WILL INCLUDE VCSH WITH CB AT SDF LATER THIS EVENING TO ACCOUNT FOR
THIS.

AS THE SYNOPTIC SCALE STORM SYSTEM RESPONSIBLE FOR THE CONVECTION
HEADS OFF TO THE EAST SUNDAY OUR WINDS WILL SWITCH AROUND TO THE
NORTHWEST. A FEW SHOWERS AND AN ISOLATED THUNDERSTORM WILL STILL BE
POSSIBLE ON SUNDAY...BUT SHOULD BE MINOR AND WIDESPREAD ENOUGH TO
OMIT FROM THE TAFS AT THIS TIME.
