The episode as NWS LOT wrote it up.
Multiple rounds of heavy rain producing storms moved across the region during the day and evening of June 15th, with an especially intense area of extreme rainfall rates during the mid-afternoon through early evening centered on the I-88 and I-290 corridors from the IL/IA state line through Chicago. This rain resulted in widespread flash flooding, including the closure of a portion of I-290 (Eisenhower Expressway). Across the metro area, there were reports and photos of cars stranded, though no injuries were reported to the NWS. The heavy rainfall and widespread storm coverage resulted in the cancellation or delays of hundreds of commercial flights in and out of Chicago. A downburst occurred in Mendota, Illinois with winds estimated to be around 80 mph resulting in mainly tree damage. While the environment was not conducive for long-lived or powerful tornadoes, a tornado threat existed with a few supercells. This included two storms in central Cook County, primarily west of downtown Chicago. Each of these had funnel cloud reports. There was also a tornado reported near the Will/Kanakakee County border, not far from I-57. An EF-1 tornado was confirmed near Symerton Illinois. The highest rainfall amounts reported were two and a half to five inches in parts of Cook, DuPage, Kane, and Will Counties, which include a large majority of Chicago and the metropolitan area.
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 Jun 15, 8:13 AM CST, 1 hour 32 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
913 AM CDT MON JUN 15 2015
.SHORT TERM...
348 AM CDT
TODAY AND TONIGHT...
HAVE ELECTED TO ISSUE A FLASH FLOOD ADVISORY FOR THE ENTIRE CWA
THROUGH THIS EVENING...AND FOR AREAS ALONG/SOUTH OF I-80 CORRIDOR
INTO EARLY TUESDAY MORNING.
SURFACE LOW PRESSURE OVER THE UPPER MISSISSIPPI VALLEY WILL MOVE
SLOWLY TO THE EAST TODAY...IN RESPONSE TO PARTIAL PHASING OF
SHEARED MID-LEVEL TROUGH OVER THE REGION AND A STRONGER SHORT WAVE
PROPAGATING ACROSS SOUTHERN CANADA AND THE UPPER MIDWEST. VERY
MOISTURE RICH LOW-MID TROPOSPHERIC AIR MASS REMAINS IN PLACE
BETWEEN HIGH PRESSURE RIDGE OVER THE SOUTHEASTERN STATES AND SLOW
MOVING COLD FRONT TRAILING THE SURFACE LOW...SETTING THE STAGE FOR
ADDITIONAL HEAVY-RAIN PRODUCING THUNDERSTORMS ACROSS THE FORECAST
AREA TODAY INTO TONIGHT. FORECAST SOUNDINGS DEPICT PRECIPITABLE
WATER VALUES OF 1.80-2.00"...WITH CORFIDI VECTORS SUGGESTING
POTENTIAL FOR SLOW FORWARD MOVING AND TRAINING/BACK-BUILDING CELLS
ESPECIALLY LATER TODAY/THIS EVENING. RELATIVELY WARM TEMPS ALOFT
AND POOR MID-LEVEL LAPSE RATES SUGGEST MINIMAL SEVERE THREAT
DESPITE 25-40 KT OF 0-6 KM BULK SHEAR THIS AFTERNOON...MAINLY IN
THE FORM OF ISOLATED DAMAGING WIND GUSTS FROM MULTI-CELL CLUSTERS.
BUT HEAVY RAINFALL IS THE MAIN THREAT...PARTICULARLY THE GROUND
PRETTY MUCH SATURATED FROM REPEATED RAINS OVER THE PAST WEEK OR
SO. AREAS SOUTH OF I-80 ARE ESPECIALLY WATER-LOGGED...WITH 5-8" OF
RAIN IN SOME SPOTS PER 7 DAY RADAR RAINFALL ESTIMATES ACROSS THE
CWA. EVEN AREAS FARTHER NORTH HAVE SEEN 1.5-2.0" FOR THE MOST
PART...WITH THE POTENTIAL FOR FLOODING TO DEVELOP QUICKLY JUST
ABOUT ANYWHERE WITH HIGH-RAINFALL EFFICIENCY STORMS.
RAIN/THUNDERSTORMS SHOULD SLOWLY DIMINISH FROM THE NORTHWEST
TONIGHT AS THE FRONT SLOWLY SAGS SOUTHEAST...BUT MAY CONTINUE IN
LIGHTER FASHION SOUTH OF I-80 AT TIMES INTO TUESDAY AS FRONT
STALLS ACROSS CENTRAL IL/IN AND WEAK SHORT WAVES CONTINUE TO
RIPPLE ALONG THE BAROCLINIC ZONE.
WARM AND HUMID CONDITIONS TODAY DESPITE CLOUD COVER AND PRECIP.
DAYTIME HIGHS EXPECTED TO RANGE FROM AROUND 80 NORTH...TO THE MID
80S IN THE SOUTHEAST ESPECIALLY WITH ANY APPRECIABLE SUN.
RATZER
&&
.LONG TERM...
401 AM CDT
TUESDAY THROUGH SUNDAY...
COLD FRONT CONTINUES TO SAG ACROSS CENTRAL IL/IN TUESDAY...WHILE
SURFACE HIGH PRESSURE SPREADS FROM THE UPPER MISSISSIPPI VALLEY TO
THE NORTHERN AND WESTERN GREAT LAKES. INDICATIONS ARE THAT A FEW
MINOR AMPLITUDE SHORT WAVES WILL CONTINUE TO RIPPLE ALONG THE
BAROCLINIC ZONE AND PRODUCING PRECIPITATION PERHAPS AS FAR NORTH
AS OUR SOUTHERN CWA COUNTIES GENERALLY SOUTH OF THE KANKAKEE AND
ILLINOIS RIVER VALLEYS. ANOTHER SHORT WAVE IS NOTED PROPAGATING
EASTWARD THROUGH ZONAL FLOW ACROSS THE NORTHERN PLAINS TUESDAY
NIGHT WHICH RESULTS IN DEVELOPMENT OF A SURFACE LOW INTO SOUTHWEST
MINNESOTA 12Z WED. BACKING LOW LEVEL FLOW ACROSS THE
SOUTHERN/CENTRAL PLAINS AND MISSISSIPPI VALLEY BEGINS TO LIFT THE
STALLED FROM BACK NORTH AS A WARM FRONT LATE TUESDAY NIGHT AND
WEDNESDAY...WITH THE POTENTIAL FOR SHOWERS/THUNDERSTORMS TO SPREAD
BACK NORTH ACROSS THE CWA BY EARLY WEDNESDAY.
IN SHORT...THE REMAINDER OF THE WEEK AND WEEKEND APPEAR TO OFFER
MORE POTENTIAL FOR PERIODIC RAINS AS THE FRONT CONTINUES TO WOBBLE
NORTH AND SOUTH ACROSS THE AREA. REMNANTS OF TROPICAL DEPRESSION
#1 CURRENTLY OVER THE GULF OF MEXICO MAY WELL MAKE ITS WAY INTO
THE OHIO VALLEY AND MIDWEST LATE IN THE WEEK. WARM AND HUMID
CONDITIONS WILL ALTERNATE WITH BRIEF PERIODS OF FLOW OFF LAKE
MICHIGAN...WITH TUESDAY AND FRIDAY MOST LIKELY TO FEATURE ONSHORE
FLOW AND COOLER TEMPS ESPECIALLY NEAR THE LAKE AS SURFACE HIGH
PRESSURE SYSTEMS PASS ACROSS THE NORTHERN LAKES. OTHERWISE...MUGGY
80S ARE EXPECTED BY DAY WITH 60S BY NIGHT AWAY FROM LAKE MICHIGAN.

.AVIATION...
//ORD AND MDW CONCERNS...UPDATED 14Z...
* A SECOND PERIOD OF SOME SHRA WITH SOME NEAR BY OR TEMPORARY TSRA
AFTER 1530 UTC.
* MULTI-HOUR TSRA WITH TEMPORARY IFR CONDITIONS LIKELY LATE
AFTERNOON INTO THE EVENING. NUMEROUS TO WIDESPREAD COVERAGE OF
STORMS IN THE TRACON AREA FAVORED DURING THAT TIME.
* VARIABLE CIGS THIS MORNING WITH TEMPORARY IFR
POSSIBLE...MAINLY OUTSIDE OF HEAVIER SHRA/TSRA.
* VARIABLE WINDS NEAR TSRA.
* WINDS BECOMING NORTHEAST NEAR SUNRISE TUESDAY WITH POSSIBLE LOW
CLOUDS.
//DISCUSSION...UPDATED 12Z...
NUMEROUS SHOWERS WITH SCATTERED STORMS WILL CONTINUE TO TRACK
NORTHEAST OVER/NEAR THE TAF SITES THROUGH MID-MORNING. THE SUBTLE
UPPER LEVEL DISTURBANCE HELPING TO AID IN THE COVERAGE OF THESE
WILL MOVE NORTH OF THE AREA BY LATER THIS MORNING AND AN EXPECTED
LULL IN COVERAGE IN SHRA/TSRA IS EXPECTED INTO EARLY AFTERNOON.
THERE STILL WILL LIKELY BE ISOLATED SHRA IN THE AREA...BUT THE
BETTER FOCUS ARRIVES LATER IN THE AFTERNOON.
AREAS OF MVFR AND IFR CIGS ARE SEEN EARLY THIS MORNING BASICALLY
FROM MLI TO ORD AND NORTH. INDIVIDUAL AIRPORTS SEE IMPROVEMENT
WITH THE RAIN SHOWERS...BUT THEN DROP BACK DOWN AFTER THE SHOWERS
BRIEFLY END. SO OVERALL CONFIDENCE ON ANY IFR DURATION IS LOW
ESPECIALLY AT MDW...BUT TEMPORARY IFR CONDITIONS ARE STILL LIKELY
AT ORD FOR AT LEAST ANOTHER HOUR OR TWO AFTER 12Z.
THE WEATHER REGIME FROM MID-AFTERNOON INTO MID-EVENING CONTINUES
TO SUPPORT A MULTI-HOUR TSRA EPISODE DUE TO A SLOW MOVING COLD
FRONT AND UPPER DISTURBANCE SHIFTING INTO A RICHLY TROPICAL AIR
MASS. WHILE SPECIFICS ON EXACT HOURS STILL REMAIN SOMEWHAT LOW
CONFIDENCE...THE MAXIMA IN COVERAGE ACROSS THE ORD/MDW AREA AND
ARRIVAL GATES LOOK TO BE JUST AFTER PEAK HEATING...SO LATE
AFTERNOON INTO EARLY EVENING.
WINDS TURN NORTHWEST BEHIND THE COLD FRONT WHICH LOOKS TO PASS
MID-EVENING OR SO. WINDS WILL THEN TURN OFF OF LAKE MICHIGAN ON
TUESDAY MORNING. A LAGGING DRY AIR PUSH MAY KEEP SOME LOW
VISIBILITY OR CLOUDS AROUND TONIGHT AND INTO EARLY TUESDAY
MORNING.
//ORD AND MDW CONFIDENCE...UPDATED 14Z...
* MED TO HIGH IN ANOTHER PERIOD OF SHRA WITH SOME POSSIBLE TS
AFTER 1530 UTC THROUGH AROUND 17 UTC.
* HIGH THAT TSRA WILL OCCUR AGAIN AT THE AIRFIELDS SOMETIME
BETWEEN MID- AFTERNOON AND MID-EVE. MEDIUM-HIGH IN TSRA BEING A
SEVERAL HOUR DURATION. LOW-MEDIUM ON SPECIFIC WINDOW OF TIME.
* LOW ON SPECIFIC TIMING AND DURATION OF ANY IFR CIGS OUTSIDE OF
SHRA/TSRA.
* MEDIUM-HIGH ON WINDS REMAINING FROM THE WEST THROUGH THIS
EVENING APART FROM NEAR STORMS.
* MEDIUM-HIGH IN WIND SHIFT TIMING TO NORTH-NORTHEAST.
//OUTLOOK FOR ORD/MDW FOR 00Z WEDNESDAY-12Z MONDAY...UPDATED 12Z...
TUESDAY NIGHT...SLIGHT CHANCE OF SHRA LATE. NORTHEAST WINDS.
WEDNESDAY...CHANCE OF TSRA. SOUTH WINDS.
THURSDAY...CHANCE OF TSRA. WEST WINDS.
FRIDAY...SLIGHT CHANCE OF TSRA. EAST WINDS.
SATURDAY-SUNDAY...CHANCE OF TSRA. SOUTHWEST WINDS.

.MARINE...
148 AM CDT
LIGHT AND VARIABLE WIND FLOW EARLY THIS MORNING SHOULD TURN MORE
SOUTH-SOUTHWEST BY MID-LATE MORNING WITH THE APPROACH OF A WEAK
LOW PRESSURE MOVING ACROSS CENTRAL WISCONSIN. THE CONTINUED MOIST
CONDITIONS SHOULD SUPPORT AREAS OF FOG OVER THE OPEN WATERS. WITH
THE LIGHT OFFSHORE COMPONENT...THINKING IMMEDIATE IL AND IN SHORE
AREAS WILL REMAIN FREE OF THE MOST DENSE FOG TODAY. A COLD FRONT
WILL EVOLVE SOUTHWARD BEHIND THE LOW THIS EVENING...GRADUALLY
TURNING WINDS NORTH. SOME FOG MAY LINGER BEHIND THIS FRONT DUE TO
LIMITED DRY ADVECTION AT FIRST...AND SOME OF THIS COULD SPILL
INTO THE IL AND IN NEARSHORES.
HIGH PRESSURE WILL QUICKLY SCOOT OVER THE LAKE TUESDAY AFTERNOON AND
NIGHT BEFORE ANOTHER LOW MOVES EASTWARD OVER THE LAKE LATER
WEDNESDAY. A WEAK FRONT ASSOCIATED WITH THIS WILL MOVE SOUTHWARD
OVER THE LAKE THURSDAY AND THURSDAY NIGHT. OVERALL THE WIND FLOW
LOOKS TO REMAIN LIGHT WITH POSSIBLE OCCASIONAL PERIODS OF 10-20 KT
FLOW OVER THE OPEN WATERS.

WDMThe Chicago radar (KLOT), 39 km away, was scanning. The volume nearest the first event began at 15:47 UTC.
6 flash flood, 1 flood, 1 thunderstorm wind, 1 tornado. Local standard time, as filed.
Several roads in Morris were flooded and closed. Nearby in Coal City, 1.49 inches of rain was measured in 35 minutes.
Several roads were flooded and closed including Route 53 at Kankakee Street and Main Street, as well as Main Street and River Street. An observer in nearby Manhattan measured 3.25 inches of rain.
Standing water one to two feet deep was reported near the intersection of Route 38 and Turkington Terrace.
Severe winds blew down around half a dozen trees on the southwest side of Mendota. One tree fell onto a home causing damage. A few utility poles were also blown down. Some homes had shingle damage.
Media reported that 25th Avenue between Belmont and Irving Park Road was flooded and closed.
Around three feet of standing water was reported on Ann Street west of Joliet Street near Community High School.
Both directions of I-290 were flooded and closed between Harlem Avenue and Desplaines Avenue.
Approximately a foot and a half of flowing water was reported near Illinois Avenue and Constitution Drive. A car was stranded in the high water.
The tornado touched down approximately 1.4 miles east of Symerton snapping large tree limbs west of Warner Bridge Road. The tornado moved east and downed trees and a power pole along Peotone-Wilmington Road just west of Gougar Road. The tornado turned southeast and impacted a Kennel and an adjacent residence where EF-1 damage was noted due to roof and tree damage. This included multiple snapped or uprooted trees. The tornado moved toward Tully Road and flipped multiple 320 lb grain bins over a garage and into a field across Tully Road. Damage was noted to metal outbuildings. The tornado continued southeast and impacted two farmsteads near Kennedy and Cedar Roads where EF-1 damage occurred to trees and a machine shed. Metal siding and additional debris from the shed was thrown a half mile downstream where the tornado dissipated in a field.
