The episode as NWS ILX wrote it up.
An upper-level disturbance interacting with a nearly stationary frontal boundary triggered scattered thunderstorms across central Illinois during the afternoon and evening of June 13th. Some of the storms produced gusty winds of around 60 mph and minor wind damage, as well as locally heavy rainfall. A brief, but heavy downpour in west central Marshall County produced isolated flash flood from Henry through Lacon to Camp Grove.
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 Lincoln, IL wrote its last area forecast discussion before the first event at Jun 13, 11:24 AM CST, 57 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 1224 PM CDT SAT JUN 13 2015 .UPDATE... ISSUED AT 1025 AM CDT SAT JUN 13 2015 HAVE MADE SOME MINOR CHANGES TO REFLECT COOLER TEMPS AND MORE SKY COVER NORTHWEST OF ILLINOIS RIVER. STRATUS ALONG AND NORTHWEST OF THE ILLINOIS RIVER HAS SET-UP A NICE THERMAL BOUNDARY FOR LATER STORM DEVELOPMENT THIS AFTERNOON. 12Z KILX SOUNDING IS A LITTLE DRIER THIS MORNING THAN YESTERDAY AND INSTABILITY AND SHEAR REMAIN MARGINAL...BUT COLUMN IS STILL 80 PERCENTILE COMPARED TO PRECIP WATER CLIMATOLOGY WHICH SUGGESTS THAT THERE REMAINS SOME POTENTIAL FOR DOWNBURST WINDS IN ANY THUNDERSTORMS THAT DEVELOP THIS AFTERNOON. BIGGEST CONCERN WILL BE EFFICIENT PRECIP PRODUCING STORMS MOVING ACROSS SATURATED GROUND. IT APPEARS THAT STORMS SHOULD BE PROGRESSIVE ENOUGH TO LIMIT PRECIP SOMEWHAT BUT IT WONT TAKE MUCH TO EXASPERATE CURRENT WATER PROBLEMS. CURRENT PACKAGE PLACES LIKELY POPS NEAR AND WEST OF THIS THERMAL BOUNDARY BY LATE AFTERNOON AND THIS SEEMS TO MATCH UP WITH 14Z HRRR AND 12Z NAM. && .SHORT TERM...(TODAY) ISSUED AT 316 AM CDT SAT JUN 13 2015 07Z/2AM SURFACE ANALYSIS SHOWS STATIONARY FRONTAL BOUNDARY ACROSS NORTH-CENTRAL ILLINOIS...EXTENDING FROM NEAR KIKK TO JUST NORTH OF KMQB. MOST OF THE KILX CWA IS IN THE WARM SECTOR...WITH SOUTHERLY WINDS AND DEWPOINTS WELL INTO THE 60S TO AROUND 70 DEGREES. THE EXCEPTION IS THE FAR NORTH FROM THE PEORIA AREA NORTHWARD WHERE WINDS HAVE SWITCHED TO THE NORTHEAST AND SLIGHTLY COOLER/DRIER AIR IS TRYING TO FILTER IN FROM THE GREAT LAKES REGION. FRONT WILL WAVER SLIGHTLY NORTHWARD TODAY...BUT WILL REMAIN CLOSE ENOUGH TO BE THE PRIMARY FOCUS FOR ADDITIONAL CONVECTION AS THE DAY PROGRESSES. MOST HIGH-RES MODEL SOLUTIONS SUGGEST A PERIOD OF DRY WEATHER THROUGH MUCH OF THE MORNING BEFORE SCATTERED THUNDERSTORMS ONCE AGAIN DEVELOP IN THE WARM/HUMID AIRMASS THIS AFTERNOON. WILL FOCUS HIGHEST POPS IN CLOSER PROXIMITY TO THE FRONTAL BOUNDARY...GENERALLY WEST OF THE I-55 CORRIDOR. FURTHER SOUTHEAST...WILL ONLY MENTION LOW CHANCE POPS ALONG/SOUTH OF THE I-70 CORRIDOR. ANY STORMS THAT OCCUR WILL BE CAPABLE OF PRODUCING LOCALLY HEAVY RAINFALL IN A SHORT AMOUNT OF TIME...AS MODEL SOUNDINGS SHOW PRECIPITABLE WATER VALUES INCREASING TO AROUND 2 INCHES. .LONG TERM...(TONIGHT THROUGH FRIDAY) ISSUED AT 316 AM CDT SAT JUN 13 2015 FRONTAL BOUNDARY WILL WAVER BACK AND FORTH ACROSS CENTRAL ILLINOIS FOR THE NEXT FEW DAYS...AS UPPER-LEVEL RIDGE REMAINS ANCHORED OVER THE SOUTHEAST CONUS AND PREVAILING WESTERLIES STAY WELL TO THE NORTH ALONG THE US/CANADIAN BORDER. WITH AMPLE DEEP-LAYER MOISTURE IN PLACE AND THE FRONT ACTING AS A FORCING MECHANISM...PERIODS OF SHOWERS AND THUNDERSTORMS ARE EXPECTED TONIGHT THROUGH AT LEAST WEDNESDAY. A FEW BOUTS OF SEVERE WEATHER WILL BE POSSIBLE FROM TIME TO TIME...HOWEVER THE BIGGEST CONCERN WILL BE HEAVY RAINFALL. THERE ARE STILL PLENTY OF UNCERTAINTIES ABOUT THE EXACT POSITION OF THE FRONT AND THE RESULTING AXIS OF HEAVIEST QPF...SO CONFIDENCE IS NOT HIGH ENOUGH TO ISSUE A FLASH FLOOD WATCH AT THIS TIME. LATER SHIFTS WILL NEED TO CONSIDER THIS POSSIBILITY...AS REPEATED RAINS ON ALREADY SOGGY SOILS WILL LIKELY LEAD TO AN ENHANCED FLOODING RISK OVER THE NEXT COUPLE OF DAYS. AS FAR AS THE SEVERE WEATHER POTENTIAL IS CONCERNED...IT APPEARS THE GREATEST RISK WILL OCCUR SUNDAY AFTERNOON AND AGAIN ON MONDAY AS THE FRONT SAGS BACK SOUTHWARD INTO CENTRAL ILLINOIS. GIVEN SURFACE DEWPOINTS HOVERING IN THE LOWER 70S...INSTABILITY WILL BE SUFFICIENT BOTH DAYS WITH CAPE VALUES EXCEEDING 1500J/KG. LIMITING FACTORS FOR WIDESPREAD SEVERE WILL BE RELATIVELY WEAK 0-6KM SHEAR OF 20-30KT AND VERY HIGH FREEZING LEVELS OF OVER 14000FT. THINK MAIN SEVERE THREATS WILL BE ISOLATED DAMAGING WIND GUSTS AND FLASH FLOODING. LATEST SPC CONVECTIVE OUTLOOKS HIGHLIGHT LOCATIONS ALONG/NORTH OF A JACKSONVILLE TO DANVILLE LINE SUNDAY AFTERNOON/EVENING...THEN ALL OF CENTRAL AND SOUTHEAST ILLINOIS ON MONDAY. AFTER A PERIOD OF UNSETTLED/WET WEATHER THROUGH WEDNESDAY...THERE ARE SOME INDICATIONS THAT THE FRONT WILL FINALLY GET PUSHED FURTHER SOUTH AND EAST OUT OF THE AREA BY THE END OF THE WEEK. HAVE THEREFORE LOWERED POPS TO JUST LOW CHANCE BY FRIDAY INTO SATURDAY. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON) ISSUED AT 1224 PM CDT SAT JUN 13 2015 CONVECTION DEVELOPING EARLY THIS AFTERNOON NEAR I-72. WILL HAVE TO INTRODUCE SOME TEMPO TSTM INITIALLY AT KSPI/KDEC/KCMI. COVERAGE WILL LIKLEY REMAIN SCATTERED. 12Z MODELS INDICATE MORE WIDESPREAD DEVELOPMENT OVER EASTERN MISSOURI AND ADVECTING INTO WESTERN ILLINOIS DURING THE 20-24Z PERIOD. KPIA WILL LIKELY HAVE THE MOST SIGNIFICANT IMPACT WITH KSPI AND KBMI RETAINING SCATTERED COVERAGE. KILX SOUNDING FROM 12Z NOT QUITE AS MOIST AS YESTERDAY...BUT STILL WELL ABOVE CLIMATOLOGY. THIS MAY LEAD TO SOME DOWNBURST ACTIVITY OR EVEN MORE WIDESPREAD WIND IF A LINE CAN GET ORGANIZED. AIRCRAFT SHOULD BE CAUTIOUS THIS AFTERNOON AND EVENING. THE MOISTURE SHOULD ALSO LEAD TO EFFICIENT STORMS THAT WILL BE CAPABLE OF REDUCING VSBYS INTO MVFR OR EVEN BRIEFLY INTO IFR. ACTIVITY SHOULD DIMINISH OVERNIGHT. SOUTH WINDS SHOULD BE SUFFICIENT TO KEEP THE DEVELOPMENT OF STRATUS NORTH OF TERMINALS. && .ILX WATCHES/WARNINGS/ADVISORIES... NONE. && UPDATE...BARKER SHORT TERM...BARNES LONG TERM...BARNES AVIATION...BARKER

EJLThe Lincoln radar (KILX), 47 km away, was scanning. The volume nearest the first event began at 18:23 UTC.
6 thunderstorm wind, 1 flash flood. Local standard time, as filed.
Two power poles were blown down on Buckhart Road just east of Rochester.
Flash flooding was reported for the third time in a week across central and western Marshall County. Only 1.50 to 2.00 of rain was reported, but due to the water laden soil, flash flooding developed rapidly. Many streets in the city of Henry were flooded. Illinois Route 17 from Lacon to Sparland was closed. Illinois Route 26 four miles north of Lacon and Illinois Route 29 near Hopewell were closed due to water and mud flowing off of hillsides onto the road. Rural roads northeast of Camp Grove were also impassable.
A tree was broken off about 4 feet above ground.
A tree was blown down onto a powerline on Old Jacksonville Road.
A power pole was snapped near the prison complex just south of Lincoln.
A large tree was blown down off 1400E about 1/4 mile south of 1700N.
A power pole was snapped on 1500E about 1/4 mile south of 1700N.
