An infant died of heat stroke after being left in a vehicle.
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.
An infant died of heat stroke after being left in a vehicle.
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 Chicago, IL wrote its last area forecast discussion before the first event at Aug 30, 12:27 PM CST, 1 hour 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 127 PM CDT FRI AUG 30 2013 .MESOSCALE DISCUSSION... 126 PM CDT COOL FRONTAL BOUNDARY EXTENDING FROM NEAR SHEBOYGAN BACK TO NEAR WATERLOO CONTINUES TO MOVE SOUTHEASTWARD. A SUBTLE SHIFT TO WEST- SOUTHWEST WINDS IS NOTED JUST AHEAD OF THE FRONTAL BOUNDARY AS WELL. VISIBLE SATELLITE SHOWS A BAND OF WELL DEVELOPED CU EXTENDING ALONG THE FRONT FROM THE LAKE MICHIGAN/WI SHORELINE WITH LESSOR ORGANIZED DEVELOPMENT AS YOU GU FURTHER WEST. RADAR MOSAIC SHOWS SCATTERED/CLUSTERED CONVECTION FROM SHEBOYGAN WEST- SOUTHWEST...WITH LATEST DEVELOPMENT AT 1815Z STILL EAST OF DELLS. EXPECT THAT THERE WILL BE GRADUAL WESTWARD DEVELOPMENT OVER THE NEXT SEVERAL HOURS AS THE BOUNDARY PUSHES SOUTHWARD. THIS WILL PUT STORMS INTO THE ROCKFORD-WAUKEGAN CORRIDOR TOWARD 21/22Z AND INTO THE CHICAGO/I-88 CORRIDOR TOWARDS 22/23Z WITH A CONTINUED SOUTHWARD MOVEMENT INTO THE EARLY EVENING. COVERAGE STILL LOOKS TO BE SCATTERED WITH SOME CLUSTERING POSSIBLE. LIMITED DEEP LAYER SHEAR REMAINS THE NEGATIVE FACTOR IN TERMS OF ORGANIZATION OR MAINTENANCE OF CELLS BUT THE 2000-3000 J/KG MLCAPE IN PLACE AHEAD OF THE FRONT WILL ALLOW FOR STRONG/PULSEY UPDRAFTS. LARGE HAIL AND DAMAGING WIND GUSTS WILL BE THE MAIN SEVERE THREATS...WITH OCCURRENCE LIKELY ISOLATED. MDB && .DISCUSSION... 351 AM CDT MAIN CONCERNS THIS FORECAST PERIOD ARE WITH HEAT AND THUNDERSTORMS TODAY WITH A HEAT ADVISORY ISSUED THIS MORNING FOR THE FAR WESTERN TIER OF COUNTIES...WINNEBAGO SOUTH TO LA SALLE COUNTY WITH HEAT INDICES REACHING 100-105 TODAY. ACTIVITY ACROSS THE CWA EARLY THIS MORNING REMAINS QUIET WITH MOSTLY CLEAR SKIES AND LIGHT WIND FIELD IN PLACE...AS HIGH PRESSURE DOMINATING. CONTINUE TO MONITOR FOG POTENTIAL ACROSS THE CWA AS WELL AS ANY LINGERING FOG/LOW CEILINGS STILL LINGERING ACROSS THE NEARSHORE WATERS. LATEST SATELLITE IMAGERY REALLY NOT DEPICTING MUCH IN TERMS OF FOG...BUT OBSERVATIONS INDICATING SOME REDUCED VIS IN FOG WITH VIS RANGING FROM 2SM TO 5SM. AM NOT TOO CONCERNED WITH ANY FURTHER WIDESPREAD REDUCTION IN VISIBILITY THIS MORNING...BUT CANNOT RULE ANY ISOLATED AREAS FALLING TO AROUND 1SM BRIEFLY BEFORE THE SUN COMES UP. SO WILL JUST MAKE MENTION OF AREAS OF FOG IN THE ZONES THIS MORNING...MAINLY FOR THE SOUTH/SOUTHEAST CWA. AREAS NEAR THE NEARSHORE HAD BRIEFLY COME DOWN TO AROUND 1SM OVERNIGHT BUT HAVE SINCE COME BACK UP TO THE 2-3SM RANGE. WHATEVER LINGERING DENSE FOG ACROSS IMMEDIATE SHORE HAS SINCE BECOME RATHER ISOLATED...AND EXPECT ANY REMAINING DENSE FOG TO QUICKLY ADVECT NORTH WITH INCREASING SOUTHERLY FLOW WHILE FURTHER ERODING. CONVECTION TO THE NORTH BEING DRIVEN BY TWO FAIRLY STOUT MID LEVEL WAVES WILL CONTINUE TO SHIFT EAST AS THESE FEATURES LIKEWISE SHIFT EAST...WITH ANY REMAINING CONVECTION MOVING ACROSS NORTH CENTRAL WISCONSIN DIMINISHING THIS MORNING. THIS WILL PAVE THE WAY FOR A DRY PERIOD THIS MORNING THROUGH EARLY AFTERNOON...WITH MOSTLY SUNNY SKIES IN PLACE. ANY MID/HIGH LEVEL CLOUD COVER CURRENTLY IN PLACE ACROSS CENTRAL WISCONSIN WILL DRIFT EAST/SOUTHEAST THROUGH LATE MORNING...WITH CURRENT SCATTERED MID DECK OVER NORTHWEST ILLINOIS SCATTERING OUT. WITH LACK OF PRECIP AND MOSTLY SUNNY SKIES...SHIFT GEARS TOWARDS HOT/HUMID CONDITIONS EXPECTED ACROSS MUCH OF THE REGION AS THERMAL AXIS SHIFTS OVERHEAD. ONGOING WAA WILL CONTINUE TODAY WITH 925/850MB TEMPS WELL SUPPORTIVE OF LOW TO 90S ACROSS THE ENTIRE CWA...WITH SLIGHTLY HIGHER TEMPS IN THE MID 90S EXPECTED ACROSS THE WESTERN CWA. MADE LITTLE CHANGES TO GOING HIGH TEMPS FOR TODAY AS RECENT GUIDANCE SUPPORTIVE OF CURRENT FORECAST. THE MAIN CHANGES I MADE FOR TODAY WERE WITH DEWPOINTS EXPECTED TODAY. DEW POINTS CURRENTLY IN THE 60S THIS MORNING ARE EXPECTED TO RISE TODAY WITH SOUTHERLY FLOW ADVECTING LOW 70 DEGREE DEWPOINTS TO THE WEST...AND DID RAISE DEWPOINTS TO REFLECT THIS. DID HAVE SOME CONCERNS WITH DAYTIME MIXING HELPING TO LOWER THESE DEWPOINTS...BUT FEEL THAT POOLING OUT AHEAD OF AN APPROACHING TROUGH/FRONT WILL HELP TO OFFSET THIS. SO HAVE MAINTAINED THE LOWER 70S DEWPOINTS THROUGH THE AFTERNOON AND WITH HIGH TEMPS EXPECTED...WAS GETTING HEAT INDICES RIGHT AROUND 100-103. WAS CONCERNED THAT THERE WAS EVEN POTENTIAL SLIGHTLY HIGHER DEWPOINTS TODAY...AND SO HAVE ISSUED AN ADVISORY FOR THE WESTERN CWA. IF THESE HIGHER DEWPOINTS COULD BE REALIZED TODAY...THERE IS EVEN A POSSIBILITY FOR THIS TO SPREAD FURTHER EAST. SO COULD POSSIBLY SEE ADVISORY EXPANDED FURTHER EAST THAN CURRENT ADVISORY. POTENTIAL FOR THUNDERSTORM DEVELOPMENT OUT AHEAD OF THIS TROUGH/FRONT REMAIN LATER THIS AFTERNOON. DESPITE GUIDANCE TRYING TO DEVELOP SCATTERED PRECIP WELL OUT AHEAD OF THESE FEATURES...HAVE KEPT POPS TIED TO FROPA LATE THIS AFTERNOON AND EARLY EVENING. WAA ADVECTION WILL NOT BE ENOUGH TO OVERCOME WARMER TEMPS ALOFT...WITH PRECIP ONCE AGAIN REMAINING ALONG FRONT. A VERY MOIST AND UNSTABLE ENVIRONMENT WITH CAPE IN UPWARDS OF 2000-2500J/KG WILL LIKELY BE IN PLACE OUT AHEAD OF THIS FRONT. ALTHOUGH I DO THINK SCATTERED DEVELOPMENT WILL BE POSSIBLE LATE THIS AFTERNOON...THINK IT WILL REMAIN MORE SCATTERED IN NATURE AS THIS FRONT WILL LIKELY BE THE BEST FORCING MECHANISM...WITH STRONGER MID LEVEL FEATURES REMAINING JUST TO THE NORTH. LIKEWISE...OVERALL BULK SHEAR NOT TOO IMPRESSIVE WITH STRONGER MID LEVEL FLOW ALSO REMAINING TO THE NORTH. DESPITE THIS LIMITING FACTORS...WOULD NOT BE OUT OF THE QUESTION FOR A FEW STORMS TO QUICKLY DEVELOP AND THEN POSSIBLY QUICKLY COME BACK DOWN...WITH ISOLATED DAMAGING WIND GUSTS POSSIBLE. DO THINK BEST TIMING FOR THUNDERSTORMS WILL BE LATE THIS AFTERNOON INTO THE EARLY EVENING...WITH BEST DEVELOPMENT THEN DIMINISHING. ALTHOUGH AM KEEPING CHANCE POPS THROUGH THE MIDNIGHT TIME FRAME AND THEN A SLIGHT CHANCE ACROSS THE SOUTHERN CWA OVERNIGHT. IT APPEARS AS IF THIS TROUGH/FRONT WILL STALL RIGHT AROUND THE SOUTHERN CWA...WITH FURTHER DEVELOPMENT POSSIBLE TONIGHT. DID EVEN KEEP CHANCE POPS ACROSS THE FAR SOUTHEAST CWA INTO SATURDAY AS THIS SYSTEM WILL BE SLOW TO EXIT. SLIGHTLY COOLER TEMPS IN THE 80S EXPECTED ON SATURDAY AND SUNDAY...WITH THUNDERSTORM CHANCES EXPECTED ONCE AGAIN ON SUNDAY. THIS SYSTEM MOVING THROUGH LATE IN THE WEEKEND AND EARLY NEXT WEEK WILL BRING MUCH COOLER TEMPS WITH 70 DEGREE TEMPS STILL EXPECTED. RODRIGUEZ && .AVIATION... //ORD AND MDW CONCERNS...UPDATED 18Z... * SCATTERED TSRA EXPECTED TO BE NEAR BY STARTING 22 OR 23Z. * WINDS TURNING NORTH-NORTHWEST THEN NORTH-NORTHEAST BEHIND THUNDERSTORMS/COOL FRONT TOWARD 00/01Z. * LOWER END MVFR CIGS EXPECTED BY MID EVENING...WITH IFR POSSIBLE EARLY SATURDAY MORNING. MDB //DISCUSSION...UPDATED 18Z... MAIN FOCUS IS SCATTERED TSRA DEVELOPMENT TO THE NORTHWEST AFFECTING THE AREA LATE THIS AFTERNOON/EARLY THIS EVENING...AS WELL AS A SHIFT TO NORTH-NORTHEAST WINDS BY MID EVENING OR SO. SURFACE ANALYSIS SHOWS A COOL FRONTAL BOUNDARY FROM JUST SOUTH OF KSBM TO NEAR KDLL TO JUST SOUTH OF KPDC. VISIBLE SATELLITE SHOWS SOME INCREASE IN CUMULUS DEVELOPMENT JUST AHEAD OF THE FRONT ACROSS SOUTHERN WISCONSIN WITH RADAR IMAGERY SHOWING SOME SCATTERED STORMS JUST WEST OF LAKE MICHIGAN. WITH BUILDING INSTABILITY THE COVERAGE OF SCATTERED STORMS SHOULD INCREASE TO THE WEST ALONG THE FRONT AND PUSH SOUTHWARD THROUGH LATE AFTERNOON. HAVE MADE LITTLE CHANGE TO THE TAFS FOR 18Z IN TERMS OF TIMING OF TS...THOUGH AM A LITTLE CONCERNED THAT ARRIVAL IN THE AREA MAY NEED TO BE SLOWED SLIGHTLY. DURATION LOOKS TO BE ON THE ORDER OF A FEW HOURS AND COVERAGE MAY BE SUCH THAT NOT ALL TERMINALS ARE DIRECTLY AFFECTED...BUT HAVE GOOD CONFIDENCE IN ACTIVITY BEING IN THE AREA. THE OTHER CONCERN WILL BE WINDS SHIFTING TO THE WEST AS THE FRONT APPROACHES THEN TO THE NORTH-NORTHWEST AND THEN NORTH-NORTHEAST SOON AFTER. THIS SHIFT MAY OCCUR AS STORMS ARE CROSSING THE AREA SO TO THE SHIFT COULD OCCUR SLIGHTLY EARLY THAN INDICATED. ONCE STORMS EXIT...STRATUS IS EXPECTED TO SPREAD IN BY MID EVENING...WITH LOWER MVFR BASES LIKELY. A FURTHER LOWERING TO IFR IS POSSIBLE LATE TONIGHT/EARLY SATURDAY. THE INCOMING AIRMASS WILL NOT BE NOTABLY DRIER BUT WIND SPEEDS LOOK TO REMAIN SLIGHTLY ELEVATED SO FOG DEVELOPMENT LOOKS UNLIKELY BUT WILL NEED TO MONITOR IF WINDS DROP OFF...ESPECIALLY OVER AREAS THAT RECEIVE RAINFALL. NORTHEAST WINDS WILL CONTINUE SATURDAY. IMPROVEMENT TO VFR IS EXPECTED WITH SCATTERING CLOUDS EARLY SATURDAY AFTERNOON...THOUGH THIS MAY TAKE A BIT LONGER AT GYY. MDB //ORD AND MDW CONFIDENCE...UPDATED 18Z... * MEDIUM-HIGH CONFIDENCE IN TIMING AND OCCURRENCE OF TSRA. * HIGH CONFIDENCE IN WINDS SHIFTING TO THE NORTH-NORTHWEST THEN NORTH-NORTHEAST...MEDIUM-HIGH CONFIDENCE IN TIMING. * MEDIUM-HIGH CONFIDENCE IN LOWER END MVFR CIGS BY MID EVENING...MEDIUM CONFIDENCE IN TIMING. LOW-MEDIUM CONFIDENCE IN SOME IFR SATURDAY MORNING. MDB //OUTLOOK FOR ORD/MDW FOR 00Z SUNDAY-12Z FRIDAY...UPDATED 12Z... SATURDAY NIGHT...VFR. SUNDAY...VFR. CHANCE OF TSRA IN THE AFTN/NIGHT. COULD SEE LOCAL MVFR/IFR CIGS. MONDAY THROUGH THROUGH...VFR. BEACHLER && .MARINE... 321 AM CDT A SERIES OF FRONTAL BOUNDARIES WILL TRAVERSE LAKE MICHIGAN OVER THE NEXT FEW DAYS. PATCHY FOG WILL LINGER THROUGH EARLY THIS MORNING...AND SHOULD DISSIPATE BY MID MORNING. FOR TODAY A SOUTHWEST FLOW WILL INCREASE WITH WINDS PUSHING TO 15 TO 25 KT ACROSS THE NORTHERN HALF OF THE LAKE...WHICH WILL QUICKLY BUILD WAVES FOR THE NORTHERN PORTIONS. THEN A FRONTAL BOUNDARY WILL STEADILY PUSH SOUTH ACROSS THE LAKE...WITH WINDS VEERING TO NORTHWEST THEN NORTH. THIS WILL ALLOW A PERIOD OF BETTER FETCH FOR THE SOUTHERN HALF AND BUILDING WAVES FOR SATURDAY. THE GRADIENT WILL TIGHTEN BEHIND THE BOUNDARY AND WAVES SHOULD EASILY BUILD TO 4 TO 6 FT SATURDAY...HOWEVER THIS APPEARS TO BE A NARROW WINDOW AS HIGH PRESSURE WILL PUSH OVER THE LAKE AND LINGER UNTIL SUNDAY MORNING. WHICH WILL ALLOW WAVES TO SUBSIDE BRIEFLY SUNDAY. THEN ANOTHER COLD FRONT WILL ARRIVE SUNDAY NIGHT...WHICH WILL BRING COOLER AIR OF THE WARMER LAKE FOR MONDAY. THE RESULT WILL LIKELY BE A PERIOD OF GUSTY WINDS...WITH BUILDING WAVES FOR MONDAY. BASED ON THE CURRENT FORECAST...MONDAY COULD PRODUCE SMALL CRAFT HEADLINES FOR THE ILLINOIS/INDIANA NEARSHORE WATERS AS WINDS WILL BE NORTHERLY FOR A PROLONGED PERIOD AND GUSTY...ALONG WITH THE COOLER AIR FLOWING OVER THE WARMER LAKE.

1 heat. Local standard time, as filed.
An infant was left in a vehicle in Burbank for 2 1/2 hours and died of heat stroke. The high temperature at O'Hare Airport was 96.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
