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, 5.4 hours before the alert went out and 196 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 JACKSON KY
1035 AM EDT SUN JUL 13 2003

MAIN SFC FEATURE TO CONTEND WITH TODAY IS INVERTED TROUGH STRETCHED
ACROSS THE MIDDLE OF THE CWA THIS MORNING. THIS HAS BEEN VERY SLOWLY
SAGGING SOUTH OVER THE PAST FEW HOURS ACCORDING TO MSAS. WITH THIS
FEATURE...COMBINED WITH EMBEDDED S/W CURRENTLY NOSING INTO S. IL AND
IN...WILL BREAK OFF A SOUTHERN ZONE GROUP WITH 30 POPS AS
AFOREMENTIONED INVERTED TROUGH SAGS SOUTH THROUGH TIME. WIND PROFILE
NOT AS STRONG AS YESTERDAY...ESPECIALLY BELOW 500 MB...HOWEVER
ENVIRONMENT...ESPECIALLY SOUTH...STILL SUPPORTIVE OF SOME GUSTY
WINDS AND SMALL HAIL. WILL HIGHLIGHT THIS IN THE HWO. ALL OTHER
ELEMENTS OF THE FORECAST LOOK ON TARGET.

.JKL...NONE.

GEOGERIAN
---------------------------------------------------------------------
515 AM EDT SUN JUL 13 2003

TSRA ACTIVITY HAS DIED DOWN FINALLY WITH AREAS OF FOG FORMING AROUND
THE CWA.  NOT MUCH OF THE FRONT LEFT WHICH SAGGED SOUTH.  ENOUGH LOW
LEVEL MOISTURE CENTRAL AND SOUTHERN CWA TO THROW IN A 20 POP FOR
AFTERNOON AND EVENING ISOLATED SHALLOW CONVECTION AS WE WILL BE
CLOSE TO THE UPPER TROUGH AXIS.  SOME RIDGING IS TAKING PLACE TO THE
WEST...BUT LOOKS AS IF WE WILL REMAIN JUST CLOSE ENOUGH TO THE
TROUGH AXIS TO NOT BE COMPLETELY OUT OF THE REALM FOR CHANCE OF
PRECIP FOR THE NEXT COUPLE OF AFTERNOONS/EVENINGS.  THE CAP GETS
WEAKER TOWARD THIS LATE AFTERNOON AND A VORT LOOKS TO SWING AROUND
THE BASE OF THE THE MID/UPPER LEVEL TROUGH ORIENTED NEAR OUR
AREA...ALTHOUGH THERE WILL BE SOME WEAK SUBSIDENCE GOING ON AND
SURFACE HIGH PRESSURE WILL WORK AGAINST RAIN PRODUCTION...SO WILL
NOT GO ABOVE 20 POPS AND KEEP NORTH DRY.  PRETTY MUCH THE SAME FOR
TOMORROW AS WE WILL REMAIN NEAR THE UPPER TROUGH AXIS ANOTHER
POSSIBLE VORT COMING DOWN THE PIKE.  A BIT BETTER LIFT...BUT LOW
LEVEL MOISTURE NOT AS GOOD.  A FRONT LOOKS LIKE IT COULD APPROACH ON
TUESDAY SO WILL HAVE ANOTHER 20 POP WITH SOME DECENT LIFT IN THE
AFTERNOON FROM DESTABILIZATION AND THE FRONT APPROACHING.  KEPT POPS
SMALL. KEPT IN SMALL POPS WED NIGHT AS FRONT NEARS.  TEMPS IN MODELS
LOOK PRETTY REASONABLE...SO DID NOT STRAY FAR FROM MINOR TWEAKS.

HEINLEIN
--------------------------------------------------------------------
1220 AM EDT SUN JUL 13 2003

SECOND UPDATE TONIGHT.  FIRST WAS TO REMOVE WATCH AND EITHER REMOVE
OR LOWER CHANCES OF PRECIP.  SINCE THEN ANOTHER SMALL E-W ORIENTED
LINE OF SHOWERS AND STORMS HAVE DEVELOPED.  DEBATING ON WHETHER OR
NOT TO INCLUDE POPS IN THIS SECOND UPDATE.  03Z SFC ANALYSIS SHOWS
WIND SHIFT LINE FROM NE KY FAINTLY BACK INTO WESTERN PARTS OF KY.
LOOKING AT WV...CAN STILL SEE A BIT OF A S/W AXIS MOVING THROUGH.
THESE TSRA WILL NOT BE AROUND FOR MUCH LONGER TONIGHT...BUT WE WILL
KEEP A 20 POP IN OUR SOUTHERN MOST TIER OF COUNTIES.

UPDATE OUT SOON.

--------------------------------------------------------------------
515 PM EDT SAT JUL 12 2003

ISOLATED TO SCATTERED SEVERE THUNDERSTORMS CONTINUE THROUGH EAST
KENTUCKY WITH ADDITIONAL THUNDERSTORMS NOW DEVELOPING FURTHER
NORTHWEST. LOW LEVEL MOISTURE AND COLD AIR ALOFT ARE COMBINING WITH
A STREAM OF SHORTWAVE ENERGY TO GENERATE AND MAINTAIN THESE STORMS.
ANTICIPATING A NEW WATCH BOX SO WILL ADJUST ZONES AS NEEDED.

THE REST OF THE FORECAST REMAINS NEARLY THE SAME AS THE MORNING
PACKAGE ASIDE FROM BEEFING UP POPS/CLOUDS AND QPF THIS EVENING. OUR
STEADY STATE PATTERN OF A LARGE SOUTHWEST RIDGE AND OHIO VALLEY
TROUGH CONTINUES THROUGH THE EXTENDED PERIOD INTO NEXT WEEKEND.
MONDAY AND TUESDAY LOOK DRY AS A HINT OF RIDGING EASES EASTWARD FROM
THE SOUTHWEST ALONG WITH SOME DRIER AIR. BY WEDNESDAY AFTERNOON MORE
MOISTURE SEEPS IN FROM THE SOUTH AND ANOTHER TROUGH BEGINS TO HEAD
FOR THE OHIO VALLEY AND SHIFTS THROUGH BY FRIDAY EVENING. WILL GO
DRY MONDAY AND TUESDAY WITH A BETTER CHANCE OF LATE DAY STORMS
WEDNESDAY AND THURSDAY...THEN ONLY SLIGHT CHANCE FOR FRIDAY
AFTERNOON AND A QUIET SATURDAY.

NO 12Z MOS AVAILABLE TO COMPARE SO MINORLY TWEAKED CURRENT TEMP
GRIDS BASED ON THE LIMITED MODEL SUITE AND CURRENT CONDITIONS.

THE GRIDS WERE IN GOOD SHAPE AND LACKING THE MESOETA DID NOT
REPOPULATE WITH ANYTHING...JUST TWEAKED EXISTING GRIDS.
