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

Nashville Metro, TN (KBNA), launched 12:00Z, 9.6 hours before the alert went out and 77 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
325 PM EDT THU JUL 21 2011

.SHORT TERM (TONIGHT AND FRIDAY)...

THIS AFTERNOON AND EVENING...

THUNDERSTORMS HAVE FIRED ALONG DIFFERENTIAL HEATING BOUNDARY AND
OUTFLOW FROM MORNING MCS OVER EXTREME SOUTHEAST KENTUCKY. MCV FROM
THIS CONVECTION IS CLEARLY EVIDENT WITH RUC OVERLAYED ON WATER VAPOR
IMAGERY. THE LAKE CUMBERLAND REGION IS CURRENTLY BEING IMPACTED AND
STORMS SHOULD SLOWLY PROGRESS SOUTHWESTWARD TOWARD THE BOWLING GREEN
REGION THROUGH THE REST OF THE AFTERNOON AND EVENING. ALTHOUGH SHEAR
IS VIRTUALLY NON-EXISTENT...SURFACE BASED INSTABILITY RANGING FROM
3000 TO 4000 J/KG WILL ALLOW FOR ISOLATED DAMAGING WIND GUSTS WITH
WET MICROBURSTS/COLLAPSING STORMS. PERHAPS THE GREATER THREAT WILL
BE FLASH FLOODING POTENTIAL AS PWATS ACROSS SOUTH CENTRAL KENTUCKY
ARE RANGING FROM 2 TO 2.25 INCHES THROUGH THE COLUMN. COMBINE VERY
MOIST COLUMN WITH SLOW STORM MOVEMENT AND POTENTIAL FOR TRAINING AND
HEAVY RAINFALL RATES ARE EXPECTED. SO FAR...BASED ON OBS FROM THE
KENTUCKY MESONET IN CUMBERLAND COUNTY...RAINFALL RATES WITH THE
STRONGEST PORTIONS OF STORMS WILL RANGE BETWEEN 1.5 AND 2 INCHES PER
HOUR...ALONG WITH EXCESSIVE CLOUD TO GROUND LIGHTNING. EXPECT THE
SEVERE THREAT TO BEGIN TO DIMINISH THIS EVENING WITH THE LOSS OF
DIURNAL HEATING...HOWEVER REMNANT OUTFLOW BOUNDARIES COULD YIELD
ISOLATED TO SCATTERED CONVECTION THROUGH MIDNIGHT.

TONIGHT AND FRIDAY...

LEFT OVER CONVECTIVE DEBRIS SHOULD GRADUALLY CLEAR TONIGHT...
ALTHOUGH COULD SEE LOWER CLOUD DEVELOPMENT FROM SOUTHWEST TO
NORTHEAST ACROSS CWA AS MOISTURE ADVECTS IN FROM THE SOUTHWEST.
CONFIDENCE IS NOT HIGH IN THIS SCENARIO AND HAVE SKIES BECOMING
MOSTLY CLEAR BY DAWN. AS HAS BEEN THE CASE...EXPECT HAZE AND SOME
PATCHY FOG TO DEVELOP TOWARD MORNING. THE VERY MILD LOW TREND WILL
CONTINUE AGAIN WITH THE MERCURY ONLY DIPPING INTO THE MID AND UPPER
70S IN MOST SPOTS. HOWEVER...ACROSS SOUTH CENTRAL KENTUCKY WHERE
OUTFLOW FROM CURRENT CONVECTION IS SWEEPING WESTWARD...EXPECT LOWS
IN THE LOWER 70S. THESE LOWS MAY OCCUR VERY CLOSE TO MIDNIGHT.

EXCESSIVE HEAT WARNING WILL CONTINUE AGAIN ON FRIDAY AS HEAT INDICES
RANGE FROM AROUND 105 IN THE EASTERN CWA TO AS HIGH AS 115 WEST OF I
65. ALTHOUGH THE LOWER END OF THIS RANGE DOES NOT QUITE MEET
EXCESSIVE HEAT WARNING CRITERIA...WILL CONTINUE EHW DUE TO PROLONGED
NATURE OF AT LEAST ADVISORY CRITERIA. HIGH TEMPERATURES ARE EXPECTED
TO BE SLIGHTLY LOW THAN TODAY/S HIGHS AS SCATTERED TO BROKEN DIURNAL
CU IS EXPECTED TO DEVELOP FAIRLY EARLY...ALONG WITH SCATTERED
CONVECTIVE DEBRIS.

HAVE LEFT CONVECTIVE COVERAGE FORECAST GENERAL ACROSS THE CWA FOR
TOMORROW AS LIMITED CAPPING SHOULD ALLOW FOR THUNDERSTORMS TO
DEVELOP WITHOUT MUCH OF A TRIGGER. AS HAS BEEN THE CASE...VERY HEAVY
RAINFALL...EXCESSIVE LIGHTNING AND ISOLATED DAMAGING WIND THREATS
WILL BE POSSIBLE WITH PULSE STORMS.

.LONG TERM (FRIDAY NIGHT - THURSDAY)...

SPRAWLING RIDGE OF HIGH PRESSURE ALOFT WILL CONTINUE THE HEAT AND
HUMIDITY THROUGH SUNDAY ACROSS OUR FORECAST AREA. HEAT INDEX VALUES
SHOULD CONTINUE TO PEAK FROM ABOUT 105 TO 110 SATURDAY SO THE
EXCESSIVE HEAT WARNING CONTINUES THROUGH THAT TIME. IN FACT...WITH
HOT AND HUMID CONDITIONS CONTINUING SUNDAY...THE WARNING MAY HAVE TO
BE EXTENDED THROUGH SUNDAY EVENING. THERE IS A HINT THAT THERE MAY
BE A FEW MORE STORMS AROUND IN THE AFTERNOON AND EVENING SATURDAY
AND SUNDAY AFTERNOONS...WHICH WOULD AFFECT TEMPS. THUS WILL LEAVE
WARNING THROUGH SATURDAY AT THIS TIME...BUT MAY NEED TO BE EXTENDED
IN LATER FORECASTS.

SCATTERED THUNDERSTORMS SHOULD BE THE RULE IN THE AFTERNOON AND
THROUGH THE EVENING HOURS OVER THE WEEKEND...MOST LIKELY WITH A
NOCTURNAL MINIMUM OVERNIGHT AND EARLY MORNING. PRECIP WATER VALUES
IN THE ATMOSPHERE AROUND 2 INCHES...MARGINAL STEERING WINDS ALOFT...
AND STEEP LOW-LEVEL LAPSE RATES WILL CONTINUE TO RESULT IN PULSE
TYPE STORMS...WITH LOCALLY TORRENTIAL RAINS (LOCAL FLOODING
POSSIBLE) AND STRONG WIND GUSTS...POSSIBLY A FEW MICROBURSTS.

ON MONDAY...A SHORTWAVE TROUGH IS PREDICTED BY MODEL GUIDANCE TO
MOVE SOUTHEAST ACROSS THE OH VALLEY. THE 12Z GFS IS SLOWEST WITH
THIS SYSTEM...WHILE THE 12Z ECMWF AND GEM ARE FASTER. THE SHORTWAVE
WILL TEMPORARILY FLATTEN THE RIDGE ALOFT AND SEND A SURFACE COOL
FRONT FROM NW TO SE ACROSS THE OH VALLEY. THIS WILL SPARK
THUNDERSTORMS ALONG AND AHEAD OF THE FRONT ON MONDAY (MAYBE EVEN
LATE SUNDAY NIGHT IF THE FASTER SOLUTION VERIFIES). THE STORMS AGAIN
WILL PRODUCE HEAVY RAIN...AND EVEN ISOLATED WIND DAMAGE ESPECIALLY
IF A LINE OF STORMS FORMS IN THE NW FLOW ALOFT AND SURGES SE.

AFTER THE FRONT PASSES LATE MONDAY OR TUESDAY (DEPENDING ON SYSTEM
SPEED)...A WELCOME BREAK IN THE HUMIDITY SHOULD OCCUR LATER TUESDAY
AND ESPECIALLY MID PART OF NEXT WEEK). IT WILL BE SLIGHTLY
COOLER...BUT LOWER HUMIDITY VALUES WILL BE THE MAIN DIFFERENCE
BEHIND THE FRONT.

NEVERTHELESS...ANY RELIEF TO THE HEAT AND HUMIDITY MID NEXT WEEK
WILL BE SHORT-LIVED AS EXTENDED MODEL GUIDANCE SUGGESTS THE UPPER
RIDGE WILL BUILD RIGHT BACK INTO THE OH VALLEY BRINGING MORE HEAT
AND HUMIDITY BACK TO THE AREA LATE NEXT WEEK.

&&

.AVIATION (18Z TAF ISSUANCE)...

EXPECT VFR CONDITIONS TO PREVAIL THROUGH THE FORECAST PERIOD OUTSIDE
OF ANY BRIEF THUNDERSTORM AT BWG AND BRIEF VISIBILITY RESTRICTIONS
TOWARD DAWN. SCATTERED CU AROUND 3 K FEET ARE EXPECTED TO DEVELOP
THIS AFTERNOON ALONG WITH SCATTERED THUNDERSTORMS ACROSS SOUTH
CENTRAL KENTUCKY. BWG WILL HAVE THE BEST SHOT AT A STRAY
THUNDERSTORM THIS AFTERNOON AROUND 4 PM OR AFTER. SURFACE WINDS
SHOULD GENERALLY BE OUT OF THE WEST BETWEEN 5 AND 10 MPH WITH
VARIABLE WINDS POSSIBLE AT BWG LATER THIS AFTERNOON DUE TO
THUNDERSTORM OUTFLOW.

GRADUALLY CLEARING SKIES THIS EVENING WILL ALLOW FOR HZ/BR TO FORM
AGAIN TOWARD DAWN AT ALL THE TAF SITES. CANNOT RULE OUT IFR
CONDITIONS AT BWG OR LEX AT THIS POINT...HOWEVER WILL LET LATER
FORECASTS NAIL DOWN DETAILS. EXPECT SCATTERED THUNDERSTORMS TO
DEVELOP AGAIN ON FRIDAY.

LIGHTNING AND BRIEF TORRENTIAL RAINFALL. ISOLATED WIND DAMAGE ALSO
CANNOT BE RULED OUT...PARTICULARLY ON MONDAY AS THE COOL FRONT
APPROACHES.
