The episode as NWS PAH wrote it up.
Thunderstorms developed along and ahead of a cold front as it pushed southeast across southern Illinois. A 500 mb shortwave trough moving southeast across the Middle Missouri Valley enhanced the storms. While the steering winds were rather weak, high moisture and instability contributed to multicell storms with torrential rain.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Paducah, KY wrote its last area forecast discussion before the first event at Jul 3, 2:49 PM CST, 1 hour 16 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
349 PM CDT SUN JUL 3 2011
.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT...
THE STORMS OVER SOUTHERN ILLINOIS HAVE BROUGHT AN END TO THE
EXTREME HEAT OVER THE NORTHERN HALF OF THE HEAT ADVISORY
AREA...AND IT HAS NOT BEEN AS BAD AS FORECAST OVER THE SOUTHERN
HALF. COULD HAVE KILLED THE ENTIRE AREA...BUT DECIDED TO LET IT
RIDE OUTSIDE OF THE CONVECTIVE OUTFLOW DEBRIS.
A CLUSTER OF STORMS APPROACHING THE ST LOUIS METRO AREA AT THIS
TIME IS ASSOCIATED WITH AN MCV. THIS DISTURBANCE SHOULD KEEP
THINGS QUITE ACTIVE ALONG THE BOUNDARY IN THE NORTHERN HALF OF THE
AREA WELL INTO THE EVENING...AND COULD PLAY HAVOC WITH FIREWORKS
DISPLAYS IN THE KEVV TRI STATE AREA. THE MID-LEVEL CAP HAS BEEN
HOLDING STRONG OVER THE SOUTHERN HALF OF THE AREA...SO AM NOT
TERRIBLY EXCITED ABOUT DEVELOPMENT INTO THE KCGI AND KPAH AREAS
THIS EVENING. THIS WILL HAVE TO BE WATCHED CLOSELY THOUGH.
SUSPECT THAT MUCH OF THE OVERNIGHT PERIOD WILL BE QUIET...BEFORE
A SIGNIFICANT MID/UPPER LEVEL TROUGH DESCENDS SOUTHEAST INTO THE
AREA MONDAY MORNING IN RESPONSE TO RISING MID/UPPER-LEVEL HEIGHTS
TO OUR WEST. THIS DISTURBANCE WILL FORCE NUMEROUS SHOWERS AND
THUNDERSTORMS ACROSS THE AREA...GENERALLY ALONG AND NORTH OF THE
PRIMARY SURFACE BOUNDARY...WHEREVER IT ENDS UP AFTER THIS EVENINGS
CONVECTION. NOT SURE IF IT WILL IMPACT THE FAR SOUTHERN BORDER
AREAS OR NOT...BUT WILL HAVE TO WATCH THIS CLOSELY AS WELL.
THE MODELS HAVE TRENDED SLOWER IN PUSHING THE MID/UPPER-LEVEL
TROUGHINESS OUT OF THE AREA MONDAY NIGHT AND TUESDAY. THE GFS
INDICATES PLENTY OF 850MB MOISTURE REMAINING OVER THE
AREA...LEADING TO ELEVATED INSTABILITY. KEPT CHANCY POPS GOING
OVER AT LEAST THE SOUTHERN HALF OF THE AREA INTO TUESDAY EVENING.
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
MOST SIGNIFICANT ADJUSTMENT IS THE SLOWER ONSET OF WEATHER FEATURES
THROUGH THE PERIOD /ADVANCED 12-18 HOURS FROM THE SATURDAY AFTERNOON
PACKAGE/.
THIS PART OF THE FORECAST WILL BE INFLUENCED BY THE POSITION AND
INTENSITY OF THE MIDDLE-UPPER LEVEL RIDGE TO THE WEST OF THE WFO PAH
FORECAST AREA.
INITIALLY /ON WEDNESDAY/...THE UPPER LEVEL RIDGE AXIS WILL BE
EXTENDING WEST TO EAST ACROSS THE WFO. THIS RIDGE AXIS WILL PROCEED
A SURFACE FRONTAL BOUNDARY DEVELOPING IN THE FASTER W-NWLY MODIFIED
ZONAL FLOW OF THE WESTERLIES FURTHER TO THE NORTH. AS THIS RIDGE
AXIS MOVES SOUTH AND RETROGRADES WEDNESDAY AFTERNOON...SCATTERED
CONVECTION SHOULD DEVELOP IN THE SLIGHTLY HIGHER SHEAR AND
INSTABILITY /DUE TO SHARPER LAPSE RATES ALOFT/ AND WORK SOUTH DURING
THE REMAINDER OF THE DAY ON WEDNESDAY AND INTO WEDNESDAY NIGHT.
AIDED BY DIURNAL EFFECTS AND CHANNELED VORTICITY ALONG THE BASE OF
THE WESTERLIES...CONVECTION SHOULD REFIRE THURSDAY
MORNING...EFFECTIVELY MOVING THE FRONTAL BOUNDARY TO THE PENNYRILE
REGION OF WEST KENTUCKY AND SOUTHWEST INDIANA BY THURSDAY AFTERNOON.
THE SFC-850 MB FRONTAL BOUNDARY WILL REMAIN ALONG THE SOUTHERN EDGE
OF THE WFO PAH FORECAST AREA ON FRIDAY AND ISOLATED CONVECTION MAY
REFIRE ALONG THIS BOUNDARY UNTIL THE UPPER RIDGE OUT IN THE CENTRAL
PLAINS MOVES IN AND WORKS EAST-SOUTHEAST INTO THE REGION LATE FRIDAY
NIGHT INTO SATURDAY. THE CAPPING EFFECTS OF THIS RIDGE...COMBINED
WITH DRIER NORTHERLY FLOW SHOULD INHIBIT ANY CONVECTIVE ACTIVITY FOR
THE WEEKEND.
THIS RIDGE IS EXPECTED TO RETROGRADE BACK TO THE WEST AGAIN /PER THE
ECMWF/ AND BRING ANOTHER CHANCE OF RAIN TO THE FORECAST AREA EARLY
NEXT WEEK /BEYOND THE END OF THIS CURRENT FORECAST PACKAGE.
FOR POPS/WEATHER/TEMPERATURE/DEWPOINT/WIND...ETC...UTILIZED A BLEND
OF THE ECMWF AND HPC GUIDANCE AND ADJUSTED CURRENT FORECAST TOWARD
THAT SOLUTION.
&&
.AVIATION...
WILL NEED TO RE-INTRODUCE VCTS TO KEVV AND EVEN KOWB THROUGH
00Z...AS STORMS DEVELOP ALONG A BOUNDARY STRUNG OUT ALONG THE OHIO
RIVER.
CONVECTION LIKELY TO PERSIST WELL INTO THE EVENING OVER THE
EVANSVILLE TRI STATE...WITH A QUIET PERIOD POSSIBLE OVERNIGHT. NOT
SURE IF THE STORMS WILL DEVELOP FAR ENOUGH SOUTH TO IMPACT KCGI
AND KPAH THIS EVENING.
STILL EXPECTING NUMEROUS SHOWERS AND THUNDERSTORMS SPREADING
SOUTH AND EAST THROUGH THE AREA MONDAY MORNING. MENTIONED MVFR
CONDITIONS WITH TS IN A PROB GROUP AT ALL SITES.
LIGHT SOUTHWEST WINDS WILL PREVAIL THIS AFTERNOON AHEAD OF THE
THUNDERSTORMS...THEN LIGHT AND VARIABLE WINDS WILL BE THE RULE.
CANNOT RULE OUT SOME FOG DEVELOPMENT TONIGHT...BUT NOT CONFIDENT
ENOUGH TO MENTION NOW...GIVEN UNCERTAINTIES IN TIMING STORMS AND ANY
SUBSEQUENT CLEARING.

HEAT INDEX VALUES WILL HOVER AROUND 105 DEGREES FOR MUCH OF THE AFTERNOON. SCATTERED TO NUMEROUS THUNDERSTORMS NEAR A WEAK COLD FRONT WILL MOVE EAST SOUTHEAST ACROSS THE EVANSVILLE TRI STATE AREA THROUGH THE EARLY AFTERNOON. OTHER SCATTERED STORMS MAY DEVELOP SOUTHWARD THROUGH THE PENNYRILE EARLY THIS AFTERNOON. LATER THIS AFTERNOON AND THIS EVENING...THUNDERSTORMS ARE EXPECTED TO SPREAD EASTWARD INTO PORTIONS OF SOUTHEAST MISSOURI AND SOUTHERN ILLINOIS. THESE STORMS MAY EVENTUALLY MOVE INTO WEST KENTUCKY AND SOUTHWEST INDIANA AS WELL. DUE TO THE DEGREE OF INSTABILITY OVER THE REGION...ANY STORM THAT DEVELOPS THIS AFTERNOON OR THIS EVENING COULD BRIEFLY BECOME SEVERE WITH DAMAGING WINDS AND LARGE HAIL THE PRIMARY THREATS. AFTER MIDNIGHT TONIGHT...A COMPLEX OF THUNDERSTORMS MAY MOVE INTO SOUTHERN ILLINOIS...SOUTHEAST MISSOURI AND SOUTHWEST INDIANA. AN ISOLATED DAMAGING WIND THREAT CANNOT BE RULED OUT WITH THESE STORMS...IF THEY REACH THE AREA. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY SCATTERED THUNDERSTORMS WILL BE POSSIBLE ON THE 4TH OF JULY...AND POSSIBLY LINGER INTO THE EVENING HOURS. ISOLATED STORMS OR CLUSTERS OF STORMS COULD PULSE UP AND REACH SEVERE LEVELS FOR BRIEF PERIODS OF TIME...ESPECIALLY IN THE AFTERNOON AND EARLY EVENING. ANOTHER CHANCE OF THUNDERSTORMS WILL ENTER THE FORECAST...MAINLY WEDNESDAY THROUGH FRIDAY. THE HIGHEST CHANCE OF ANY SEVERE STORM POTENTIAL RIGHT NOW LOOKS TO BE FROM WEDNESDAY INTO WEDNESDAY NIGHT AS ANOTHER WEAK COLD FRONT PUSHES INTO THE REGION. MINOR TO MODERATE FLOODING WILL CONTINUE ON SOME RIVERS ACROSS THE REGION...ESPECIALLY ALONG THE MISSISSIPPI RIVER. REFER TO THE LATEST RIVER FLOOD WARNINGS AND STATEMENTS FOR THE LATEST RIVER FLOOD INFORMATION. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION CANNOT BE RULED OUT OVER PORTIONS OF THE AREA TODAY...TONIGHT AND MONDAY. DRS
