Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

Area forecast discussion, Apr 24, 4:48 PM CDT, 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
548 PM EDT SAT APR 24 2010

...MESOSCALE UPDATE...

SEVERE SQUALL LINE HAS DEVELOPED FROM HAWESVILLE KY TO EAST OF
MEMPHIS. THIS SQUALL LINE WILL CONTINUE TO PLOW TO THE NORTHEAST AND
SHOULD MAINTAIN ITS INTENSITY THROUGH AT LEAST 00Z. DESPITE THE
FORMATION OF A LINE...WE MUST NOT RULE OUT THE CONTINUING
POSSIBILITY OF TORNADOES. INDEED...SEVERAL STRONGLY ROTATING STORMS
HAVE ALREADY BEEN NOTED ALONG THE LEADING EDGE OF THE LINE.

THE ATMOSPHERE IS MOST UNSTABLE IN THE BOWLING GREEN AREA. WHILE
INSTABILITY IN CENTRAL KENTUCKY IS NOT NEARLY AS ROBUST AS TO THE
SOUTHWEST...SHEAR IS STILL VERY STRONG AS SEEN ON LVX VWP. ALL
INTERESTS IN CENTRAL KENTUCKY MUST CONTINUE TO BE ON GUARD FOR
POSSIBLE ADDITIONAL TORNADOES EARLY THIS EVENING.

SEVERE THREAT WILL SHIFT EASTWARD THIS EVENING AS LOW LEVEL JET
INCREASES TO 60KT AND PROGRESSES TO THE EAST OVER CENTRAL KENTUCKY.
SHEAR WILL REMAIN HIGH AS WELL. INSTABILITY WILL DECREASE AFTER
00Z...BUT ROTATING STORMS WILL STILL BE POSSIBLE ACROSS CENTRAL
KENTUCKY AND FAR SOUTHERN INDIANA.

THE SEVERE THREAT SHOULD END FROM WEST TO EAST BETWEEN 03Z AND 06Z.

.SHORT TERM (TONIGHT AND SUNDAY)...

FOCUS CONTINUES ON SEVERE WEATHER THREAT. EXPECT MULTIPLE MESOSCALE
DISCUSSIONS TO COME UP FOR THE REST OF THE AFTERNOON AND EVENING.
EXPECT THE SEVERE THREAT TO END BY MID EVENING...BUT SHOWER CHANCES
WILL CONTINUE OVERNIGHT AS MID LEVEL DRY AIR WILL LIMIT DEEP
CONVECTION. BY SUNDAY...FRONT WILL NOT COME THROUGH UNTIL LATER
SUNDAY. SO COULD SEE SOME LOW TOPPED CONVECTION DEVELOP WITH STEEP
LOW LEVEL LAPSE RATES. HAVE WORDING FOR STORMS IN THE AFTERNOON IN
THE GRIDS.

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

JUST A BROAD-BRUSH DISCUSSION FOR THE EXTENDED THIS ISSUANCE DUE TO
SIGNIFICANCE OF INCOMING SEVERE THREAT.

LARGE VERTICALLY STACKED LOW OVER INDIANA AT THE START OF THE PERIOD
WILL DRIFT EAST TOWARD THE ATLANTIC COAST BY 00Z TUESDAY.  BROAD
UPPER TROF ASSOCIATED WITH SURFACE LOW MAINTAINS AXIS OVER EASTERN
U.S. THROUGH WEDNESDAY...KEEPING COOLER NORTHERLY FLOW FOR THE
AREA...RESULTING IN TEMPS AT OR BELOW NORMS FOR THE FIRST HALF OF
THE WEEK.  BY THURSDAY...UPPER RIDGE MOVES INTO THE OHIO VALLEY
ALLOWING FOR RETURN OF SOUTHERLY FLOW AND TEMPS WARMING BACK INTO
THE 70S FOR HIGHS AND 50S FOR LOWS....UP FROM 40-MID 60 RANGE FOR
MIN/MAX RANGE IN THE FIRST HALF OF WEEK.

ANOTHER BROAD UPPER TROF DEVELOPS OVER THE WESTERN U.S. BY
FRIDAY...WITH THE CAHNCE FOR THUNDERSTORMS RETURNING FOR NEXT
WEEKEND.

BY EARLY SUNDAY...THE STRONG STORM SYSTEM RESPONSIBLE FOR SATURDAY'S
STORMS WILL MORPH INTO A VERTICALLY STACKED...FILLING...OCCLUDED
CYCLONE JUST SOUTH OF CHICAGO. ALTHOUGH BEGINNING TO WEAKEN...THE
PRESSURE ASSOCIATED WITH THE SURFACE LOW IS STILL FORECAST TO BE A
QUITE DEEP 885MB OR SO. DRY MID LEVEL AIR WILL HAVE OVERSPREAD THE
COMMONWEALTH DURING THE PREDAWN HOURS IN THE WAKE OF A COLD FRONT.
HOWEVER...SEASONABLY COLD AIR WILL STILL LIE WELL NORTH OF THE OHIO
RIVER THROUGH MID AFTERNOON SUNDAY. THIS COOLER AIR WILL SAG
SOUTHWARD BEHIND A SECONDARY COLD FRONT ASSOCIATED WITH THE ARRIVAL
OF THE BY NOW ELONGATED 500MB TROUGH.

AFTER A PARTLY CLOUDY...BREEZY BUT STILL MILD SUNDAY
MORNING...STEEPENING LAPSE RATES COUPLED WITH HEIGHT FALLS
ASSOCIATED WITH THE APPROACHING 500MB TROUGH WILL LIKELY SPARK
SCATTERED FAST MOVING LOW-TOPPED SHOWERS AND THUNDERSTORMS DURING
THE AFTERNOON AND EVENING HOURS. THESE STORMS WILL HAVE TO POTENTIAL
TO BRING GUSTY WINDS AND PERHAPS SOME SMALL HAIL. INITIALLY...THE
BEST COVERAGE WILL LIE ACROSS SOUTHERN INDIANA. BY EVENING...THIS
CONVECTION WILL SAG SOUTH TOWARDS CENTRAL KENTUCKY.

WILL CONTINUE A CHANCE FOR SHOWERS SUNDAY NIGHT ACROSS THE ENTIRE
AREA AS THE 500MB TROUGH AXIS MOVES OVERHEAD. COLDER AIR WILL ARRIVE
AND WILL KEEP MONDAY QUITE CLOUDY WITH AFTERNOON HIGHS STRUGGLING TO
EXCEED 60 ALONG AND NORTH OF INTERSTATE 64.

LATE MONDAY AS A LONGWAVE TROUGH DEVELOPS ACROSS NEW ENGLAND...AS
SECONDARY 500MB TROUGH WILL SLIDE SOUTHEAST TOWARDS THE LOWER OHIO
VALLEY. THIS WILL CROSS THE AREA TUESDAY AFTERNOON AND WILL LIKELY
BRING A SECOND CLOUDY COOL DAY WITH A CHANCE OF SOME LIGHT SHOWERS.

.WEDNESDAY THROUGH FRIDAY...

A SUBSTANTIAL WARMING TREND WILL BEGIN WEDNESDAY THAT WILL LIKELY
BRING HIGH TEMPERATURES WELL BACK UP INTO THE MID TO UPPER 70S
THURSDAY THROUGH SATURDAY. THE UPPER AIR PATTERN WILL AMPLIFY
WEDNESDAY AS THE FIRST OF A SERIES OF STRONG STORMS MOVE ACROSS THE
PACIFIC NORTHWEST. EVENTUALLY...A TROUGH WILL DEVELOP ACROSS THE
ROCKIES BY THE EARLY PART OF NEXT WEEKEND. CORRESPONDING...RIDGING
ACROSS THE WESTERN PLAINS WILL GRADUALLY TRANSLATE EAST AND BRING
RISING HEIGHTS ACROSS THE LOWER OHIO VALLEY. AT THE SURFACE...HIGH
PRESSURE WILL MOVE ACROSS THE COMMONWEALTH WEDNESDAY AND BECOME
ESTABLISHED ACROSS THE SOUTHEASTERN STATES BY LATE FRIDAY.

EXPECT MOSTLY SUNNY SKIES AND LIGHT WINDS WEDNESDAY. SOUTHERLY FLOW
WILL BEGIN THURSDAY...BRINGING PARTLY CLOUDY SKIES AND THE START OF
A NICE WARMUP.

&&

.AVIATION (18Z TAF ISSUANCE)...

WIDESPREAD SHOWER AND THUNDERSTORM ACTIVITY EXPECTED INTO THE EARLY
EVENING HOURS AT THE TAF SITES. GIVEN HIGH POTENTIAL FOR SEVERE
WEATHER...NOT EXPECTING THE BEST FLYING CONDITIONS DURING THIS
PERIOD. FOR NOW HAVE MVFR TO IFR CONDITIONS IN THE TAFS AS WELL AS
30-35 KNOT WINDS...THOUGH WINDS CERTAINLY COULD BE STRONGER. EXPECT
SEVERE ACTIVITY TO WIND DOWN BY MID EVENING...BUT SHOWERS ARE
POSSIBLE AS THE DRIVING LOW WILL STALL OVER ILLINOIS. COULD BE
ANOTHER ROUND OF STORMS SUNDAY LATE MORNING AND AFTERNOON.
