The episode as NWS PAH wrote it up.
Clusters of strong thunderstorms moved southeast across southern Illinois. A cluster briefly evolved into a bowing line of storms that produced isolated damaging winds. The storms occurred ahead of a cold front as it moved east across eastern Missouri and into western Illinois.
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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
1147 PM CDT SAT AUG 14 2010
.UPDATE...
UPDATED FOR 06Z AVIATION FORECAST DISCUSSION.
&&
.DISCUSSION...
PRIMARY FORECAST CONCERNS REMAIN THE HEAT AND THUNDERSTORM
CHANCES/INTENSITY AS WE TRANSITION TOWARD THE MUCH ADVERTISED
COOLER/LESS HUMID AIR MASS.
IN THE NEAR TERM....THERE IS A SLIGHT RISK OF SEVERE STORMS OVER
MAINLY W KY INTO TONIGHT AS A RESULT OF CONVECTIVE INSTABILITY AND A
MCV MOVING ACROSS IL AND IN. LOCALLY HEAVY RAINFALL IS POSSIBLE
GIVEN THE MOIST BOUNDARY LAYER.
THE ADVERTISED SURFACE COLD FRONT...OVER NORTHERN MO/NW IL THIS
AFTERNOON IS STILL ON TRACK TO MOVE SOUTHEAST ACROSS OUR FA ON
SUNDAY...NEARING THE OH RIVER SUN AM AND PUSHING ACROSS W KY IN
THE AFTERNOON. A COUPLE OF 500MB SHORTWAVES PROGRESSING ESE WILL
HELP TO SUPPORT CONVECTIVE CHANCES THROUGH TONIGHT AND THEREFORE
WILL MAINTAIN CHANCE POPS TONIGHT. WILL ALSO MAINTAIN SMALL POPS
SUNDAY BUT DECREASE FROM MORNING TO AFTERNOON FROM NW TO SE. WILL
KEEP SMALL POPS OVER THE CWA SE CORNER/SOUTHERN PENNYRILE ONLY FOR
MONDAY GIVEN FRONTAL PROXIMITY TO OUR SOUTH.
REGARDING THE HEAT ISSUE...AM VERY DOUBTFUL THAT WE WILL BE OUT OF
THE WOODS AS FAR AS MEETING CRITERIA FOR AT LEAST A HEAT ADVISORY
(100 TO 105 HEAT INDICES WHEN AT LEAST 4 CONSECUTIVE DAYS) AND IT
IS VERY POSSIBLE THAT WE COULD AGAIN MEET EXCESSIVE HEAT WARNING
CRITERIA SUNDAY ACROSS THE SOUTH. ALSO THE INTRUSION OF DRIER AIR
WILL BE MORE OF A GRADUAL PROCESS SUNDAY WITH DEWPOINT PROJECTIONS
STILL IN THE LOWER TO MID 70S FOR MUCH OF THE DAY. GIVEN THE
TRANSITIONING AIR MASS AND UNKNOWNS AT THIS TIME ABOUT MCS
DEVELOPMENTS ETC. IT WILL LIKELY UNFOLD SOMEWHAT DIFFERENTLY THAN
EXPECTED. THAT SAID WILL ISSUE A HEAT ADVISORY ACROSS THE SOUTHERN
2/3 OF THE FA SINCE EXPECT TO EASILY MEET ADVISORY CRITERIA
THERE....AND TO AVOID POTENTIAL DOWNPLAYING OF A CONTINUED HEAT
THREAT FOR THIS MAJOR HEAT WAVE.
SURFACE HIGH PRESSURE MOVING FROM THE PLAINS EAST ACROSS IL/IN AND
EVENTUALLY THE EASTERN GREAT LAKES REGION WILL PROVIDE THE MUCH
ANTICIPATED COOLER LESS HUMID AIR THROUGH THE EARLY AND MIDDLE PART
OF THE WEEK. GIVEN THE RETURN FLOW AS THE HIGH MOVES OFF TO THE
EAST...WILL KEEP A SMALL POP INTO MID WEEK ACROSS THE SOUTH.
FOLLOWED GUIDANCE TEMPS FAIRLY CLOSELY WITH MAIN FORECAST PACKAGE
CHANGE BEING TO DECREASE MONDAY NIGHT MINS A COUPLE OF DEGREES.
EXTENDED...
SHRTWV ENERGY IN THE NEARLY ZONAL FLOW ALOFT WILL PASS QUICKLY MID
WEEK...RESULTING IN LITTLE PCPN FOR MOST OF THE PAH FCST AREA. IN
ITS WAKE...A WARM FRONT IS EXPECTED TO MOVE NORTH ACROSS THE REGION
AS THE MID LEVEL FLOW TURNS MORE NNW. HIGHEST MOISTURE WILL BE IN
THE SERN CORNER...THUS THE HIGHEST PROBABILITY OF PCPN WILL BE
THERE...ATTM A SMALL CHC THROUGH FRI. INTO THE WEEKEND...A MORE
SIGNIFICANT SHRTW MAY INCREASE MOISTURE ACROSS THE REGION AND DRIVE
A SFC COLD FRONT THROUGH...INCREASING PCPN CHCS. IT APPEARS ATTM THAT
TEMPS WILL REMAIN REASONABLE IN THE EXTENDED FCST.
&&
.AVIATION...
AS EXPECTED...SCATTERED SHOWERS AND STORMS ARE FINALLY DEVELOPING
AHEAD OF A COLD FRONT TO OUR NORTHWEST. UNTIL THIS FRONT MOVES ON
THROUGH...THERE WILL BE A THREAT FOR SHRA/TSRA...SO HAVE A CB IN
FOR A GOOD PORTION OF THE TAF...NOT BEING ABLE TO PINPOINT EXACT
TIMING AND ALSO DUE TO THE SCT NATURE OF THE CONVECTION. THE
FRONT WILL MOVE INTO THE AREA SUNDAY MORNING/AFTERNOON. WINDS WILL
SHIFT AROUND TO THE NW AS THIS OCCURS. WINDS JUST ABOVE THE SFC
SHOULD STAY UP OVNGT...PRECLUDING SIGNIFICANT FOG.
