A man died from heat stroke after three days with highs in the low to mid 90s.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS LOT wrote it up.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
503 PM CDT WED SEP 11 2013
.DISCUSSION...
249 PM CDT
SYNOPSIS...A COUPLE OF COLD FRONTS PASS THROUGH THE REGION BRINGING
SCATTERED SHOWERS AND MUCH COOLER AIR TO THE REGION.
TODAY AND TONIGHT...
A COLD FRONT IS OVER NORTHERN IL AND STRETCHES INTO CENTRAL MI.
SHOWERS AND A FEW STORMS ARE FIRING ALONG THE FRONT...WITH THE
STRONGER STORMS ASSOCIATED WITH VARIOUS BOUNDARIES OVER NORTHERN
IL. THE TWO MAIN BOUNDARIES APPEAR TO BE THE LAKE BREEZE OVER
NORTHERN COOK COUNTY AND AN OUTFLOW BOUNDARY FROM THE NORTHERN
SHOWERS THAT STRETCHES FROM PAW PAW TO ELMHURST. EXPECTING MUCH OF
THE SAME THIS AFTERNOON WITH SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS. THE STRONGER STORMS WILL BE ASSOCIATED WITH BETTER
AREAS OF FORCING. LATEST RAP ANALYSIS INDICATE CAPE VALUES UP TO
2000 J/KG OVER THE REGION. THE BEST 0-6 KM SHEAR IS NORTH OF I-88
WHERE SHOWERS HAVE STABILIZED THE ENVIRONMENT. AREAS SOUTH OF I-88
AND THE COLD FRONT REMAIN RELATIVELY CLEAR WITH LOW LEVEL LAPSE
RATES AT OR ABOVE 9C/KM BUT UPPER LEVEL LAPSE RATES REMAIN WEAK
AROUND 6C/KM. SHEAR IS ALSO LESS THAN DESIRABLE SO EXPECTING
SHOWERS AND STORMS TO DEVELOP AS THE FRONT SINKS SOUTH...BUT NOT
ANTICIPATING ANY WELL ORGANIZED STORMS. MAIN THREAT REMAINS
ISOLATED DAMAGING WINDS OR A DOWNBURST GIVEN PWAT VALUES 1.5+ WHICH
IS +2SD ABOVE NORMAL FOR SEPTEMBER. SOUNDINGS ALSO FEATURE INVERTED
VS BELOW 700MB. WIDESPREAD SEVERE WEATHER IS NOT LIKELY GIVEN THE
MARGINAL CONDITIONS AND WEAK FORCING.
EXPECTING THE FRONT AND ASSOCIATED PRECIP TO MOVE SOUTH OF I-88 LATE
THIS AFTERNOON INTO THIS EVENING AND CONTINUE TO THE SOUTH
OVERNIGHT. EXPECTING SKIES TO THIN OVERNIGHT AND TEMPS TO DROP TO
AROUND 60 NORTH OF I-88 AND THEN INTO THE MID TO UPPER 60S ALONG AND
SOUTH OF I-80...AND DOWNTOWN.
THURSDAY THROUGH FRIDAY...
THE TROUGH AXIS OF THE UPPER LEVEL TROUGH PASSES OVER THE REGION
TOMORROW ALONG WITH A SECONDARY COLD FRONT. NOT EXPECTING ANY
PRECIP WITH THE SECONDARY FRONT...BUT TEMPS WILL FALL. GUIDANCE
SUGGESTS 850MB TEMPS WILL BE -2 TO 6 DEGREES C BY FRIDAY MORNING.
GIVEN THAT LAKE WATER TEMPS ARE AROUND 21 DEGREES C LAKE EFFECT RAIN
BECOMES A CONCERN THURSDAY NIGHT THROUGH FRIDAY. WINDS TURN OUT OF
THE NORTHEAST AHEAD OF THE BUILDING HIGH PRESSURE...WHICH CREATE AN
ELONGATED FETCH DOWN THE LAKE. AS SUCH HAVE A SLIGHT CHANCE TO
CHANCE OF LIGHT SHOWERS OVER LAKE AND COOK COUNTIES IN IL THURSDAY
NIGHT. WINDS SHIFT TO THE NORTH FRIDAY...THEREFORE SHIFTED THE
CHANCE OF SHOWERS OVER WESTERN COOK COUNTY AND NORTHERN IN FRIDAY.
THE SHOWERS SHOULD DISSIPATE FRIDAY AFTERNOON AS TEMPS WARM ALOFT
DUE TO THE BUILDING HIGH PRESSURE.
TEMPS LATE THIS WEEK WILL BE MUCH MORE FALL LIKE...AND BELOW
NORMAL. THURSDAYS HIGHS WILL BE IN THE MID 70S TO MID 80S...AND
FRIDAYS HIGHS WILL BE IN THE MID TO UPPER 60S. OVERNIGHT LOWS WILL
BE IN THE 50S THURSDAY AND 40S ON FRIDAY.
EXTENDED...SATURDAY THROUGH TUESDAY...
THE UPPER LEVEL RIDGE REMAINS OVER TEXAS WHILE THE NOW MOBILE UPPER
LEVEL LOW WEAKENS AND DISSIPATES SATURDAY NIGHT. A SHORTWAVE TROUGH
PASSES OVER SOUTHERN WI/NORTHERN IL SATURDAY NIGHT THEN THE TROUGH
AXIS OF A LOW OVER HUDSON BAY ROTATES OVER THE REGION SUNDAY.
RIDGING FOLLOWS BEHIND THE TROUGH INTO MID NEXT WEEK.
AT THE SURFACE THE EXTENDED BEGINS WITH HIGH PRESSURE DEPARTING TO
THE SOUTHEAST. A WEAK SURFACE TROUGH PASSES OVER THE REGION SUNDAY
BRINGING A CHANCE OF RAIN AND THUNDERSTORMS. HIGH PRESSURE MOVES IN
BEHIND THE TROUGH MONDAY WITH A RETURN TO DRY CONDITIONS. THE HIGH
SHIFTS EAST AND A SHORTWAVE TROUGH MAY BRING ANOTHER ROUND OF
SHOWERS AND STORMS TUESDAY NIGHT INTO WEDNESDAY. OVERALL NOT SEEING
A GOOD CHANCE FOR THE SOAKING RAIN WE NEED.
BELOW NORMAL TEMPS ARE EXPECTED OVER THE WEEKEND WITH HIGH TEMPS IN
THE LOW 70S AND OVERNIGHT LOWS IN THE 50S. A WARM UP TO MORE
SEASONAL TEMPS IS EXPECTED TUESDAY INTO WEDNESDAY.

//ORD AND MDW CONCERNS...UPDATED 22Z...
* WIND DIRECTION THROUGH THIS EVENING. CMS
//DISCUSSION...UPDATED 22Z...
WINDS ARE RETURNING TO A WEST/NORTHWEST DIRECTION AFTER VARIOUS
BOUNDARIES/WIND SHIFTS ALONG WITH A FEW TSRA MOVED THROUGH THE
AREA. CONFIDENCE REGARDING SOME FORM OF WESTERLY WINDS IS MEDIUM
INTO THIS EVENING...BUT THE ACTUAL DIRECTIONS COULD BE QUITE
VARIABLE AT TIMES. WIND SPEEDS SHOULD REMAIN UNDER 10 KTS. ANY
ADDITIONAL SHRA/TSRA WILL REMAIN SOUTH AND EAST OF ORD/MDW. CMS
PREVIOUS 18Z DISCUSSION...
MAIN FORECAST CONCERNS THIS AFTERNOON REVOLVE AROUND THE DETAILS OF
A COLD FRONT THAT IS CURRENTLY VERY DIFFUSE AND UNORGANIZED...
STRETCHING ROUGHLY FROM NEAR MKE SOUTHWEST TO MLI. LIGHT RETURNS
ARE SHOWING UP ON RADAR INDICATING A FEW SHOWERS ALONG THE
FRONT...AND SATELLITE IMAGERY INDICATES THAT THERE IS SOME VERTICAL
GROWTH...BUT THICK MID LEVEL CLOUD CANOPY ADVECTING OVER THE AREA
WILL ONLY INHIBIT FURTHER DESTABILIZATION THIS AFTERNOON...WHICH
ALREADY WAS A CONCERN LEADING UP TO THIS POINT. IN ADDITION TO THE
MEAGER INSTABILITY...FORCING IS VERY WEAK...MAINLY ASSOCIATED WITH
THE VERY MODEST CONVERGENCE ALONG THE FRONT ITSELF. LITTLE IF ANY
UPPER LEVEL SUPPORT IS NOTED THIS AFTERNOON. SEVERAL HI-RES
MODELS SEEM TO FALL IN TWO CAMPS...SHOWING THE CURRENT ACTIVITY TO
OUR WEST INCREASING IN INTENSITY AND COVERAGE OVER THE NEXT COUPLE
HOURS...OR THE CURRENT ACTIVITY TO OUR WEST STAYING AS IS OR
FADING. GIVEN THE AFOREMENTIONED LACK OF FORCING...LEANING TOWARDS
THE FRONT MORE OR LESS REMAINING QUIET AS IT IS NOW AS IT MOVES
OVER THE TERMINALS. IF THE FRONT WERE TO LIGHT UP LATER TODAY...IT
MAY BE SOUTH OF THE TERMINALS AS THE FRONT MOVES INTO MORE
UNSTABLE AIRMASS. WITH THAT IN MIND...REMOVED THUNDER MENTION FROM
THE TERMINALS...EXCEPT FOR GYY WHICH SEEM TO HAVE THE BEST CHANCE
FOR POSSIBLY SEEING SOMETHING MID TO LATE AFTERNOON. OVERALL
CONFIDENCE IN THE EVOLUTION THE NEXT FEW HOURS IS PRETTY LOW AND
WILL HAVE TO MONITOR RADAR TRENDS CLOSELY FOR FURTHER ADJUSTMENTS.

142 PM CDT
A STRONGER COLD FRONT IS EXPECTED TO PUSH DOWN THE LAKE TONIGHT AS
LOW PRESSURE TRACKS FROM ONTARIO INTO QUEBEC. THE WINDS BEHIND THIS
FRONT WILL BECOME NORTHERLY UP TO 25 KT INTO THURSDAY. THESE
NORTHERLY WINDS MAY INCREASE A BIT MORE CLOSER TO 30KT FOR A PERIOD
LATER THURSDAY AND INTO THURSDAY NIGHT AS A MUCH COOLER AIRMASS
DROPS ACROSS THE LAKE AHEAD OF A CANADIAN HIGH PRESSURE SYSTEM. THE
WINDS WILL LIKELY REMAIN ELEVATED OUT OF THE NORTH INTO FRIDAY
BEFORE THE SURFACE HIGH CENTERS ITSELF OVER THE LAKE BY FRIDAY
EVENING...LEADING TO A PERIOD OF LIGHT AND VARIABLE WINDS. FOLLOWING
THE PASSAGE OF THIS HIGH...THE WINDS SHOULD BECOME SOUTHERLY AGAIN
FOR SATURDAY...BEFORE YET ANOTHER COLD FRONT LIKELY DROPS SOUTH
ACROSS THE LAKE LATER IN THE WEEKEND SETTING UP ANOTHER PERIOD OF
STRONGER NORTHERLY FLOW.
THESE STRONG NORTHERLY WINDS WILL LEAD TO SOME HIGH WAVES OF 6 TO 10
FT ACROSS FAR SOUTHERN LAKE MICHIGAN THURSDAY NIGHT INTO
FRIDAY...INCLUDING THE NEAR SHORE WATERS. THEREFORE A SMALL CRAFT
ADVISORY WILL BE NEEDED FOR THE ILLINOIS AND INDIANA NEAR SHORES
FROM THURSDAY AFTERNOON THROUGH FRIDAY NIGHT.
THERE IS ALSO A SMALL THREAT FOR SOME WATER SPOUTS LATE THURSDAY AND
INTO FRIDAY. HOWEVER...IT APPEARS TO BE A SMALL WINDOW AS UPPER
LEVEL TEMPERATURES WILL BEGIN TO WARM QUICKLY EARLY
FRIDAY...LIMITING THE OVERALL DEPTH OF THE INSTABILITY. IN SPITE OF
THIS...WE WILL MAINTAIN THE CHANCES FOR SOME ISOLATED WATER SPOUTS.

A man died in his home from heat stroke. High temperatures at O'Hare Airport from September 9th to the 11th were 94, 95, and 91 degrees respectively.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
