The episode as NWS LOT wrote it up.
A line of thunderstorms sank south across far northern Illinois overnight June 21st into the 22nd. Thunderstorms redeveloped over east central Illinois later in the morning causing strong winds and flooding.
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 22, 12:03 AM CST, 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 103 AM CDT SAT JUN 22 2013 .DISCUSSION... 927 PM CDT SHOWERS HAVE FINALLY EXITED THE CWA WHILE NEW SHOWERS ARE SPROUTING OVER WISCONSIN. UPSTREAM THERE ARE TWO CONVECTIVE COMPLEXES...ONE OVER SOUTHERN MINNESOTA AND THE OTHER OVER SOUTHERN SOUTH DAKOTA/WESTERN NEBRASKA. LOCALLY...THE ATMOSPHERE HAS STABILIZED BEHIND THE LINE OF STORMS. THE 00Z DVN SOUNDING AND AMDAR SOUNDINGS ALL INDICATE A SIGNIFICANT CAP BETWEEN 850 AND 700 MB. HOWEVER THEY ALSO FEATURE 1000+ J/KG OF MIXED LAYER CAPE. PWAT VALUES ARE ALSO AROUND 1.5 INCHES SO THE ATMOSPHERE REMAINS JUICY THIS EVENING. DID NOT ADJUST LOW TEMPERATURES OR DEWPOINTS FOR TONIGHT BY MUCH...WITH A MUGGY EVENING STILL ON TAP. NOW TO THE TRICKY PART...PRECIP CHANCES TONIGHT. THE GENERAL PATTERN IS FOR THE LOW LEVEL JET TO STRENGTHEN WITH THE NOSE OF THE JET OVER SE IA/W CEN IL/SW WI. NEW CONVECTION IS PROGGED TO FIRE OVER ALONG THE NOSE OF THE JET...AND GIVEN THE ENVIRONMENT EXPECTING ELEVATED CONVECTION. FOR TIMING...THINKING THE CHANCES WILL BE BEST ALONG AND NORTH OF I-88 AFTER 06Z THROUGH THE MORNING. UPDATED THE POP/WX FORECAST TO REFLECT THE TREND OF INCREASING PRECIP CHANCES THROUGH THE LATE EVENING AND OVERNIGHT. BUT OVERALL CONFIDENCE IS STILL LOW TO MEDIUM WITH HOW/IF CONVECTION WILL EVOLVE THROUGH THE MORNING. JEE //PREV DISCUSSION... 329 PM CDT SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT... THE MAIN FORECAST CONCERNS DEAL WITH CHANCES FOR CONVECTIVE ACTIVITY AND TEMPERATURES/HEAT INDICES OVER THE NEXT FEW DAYS. SCATTERED THUNDERSTORMS CONTINUE THIS AFTERNOON...BUT THE STRONGEST STORMS HAVE NOW SHIFTED ACROSS SOUTHERN SECTIONS OF THE AREA. DEEP LAYER SHEAR IS FAIRLY WEAK TO THE SOUTH...SO NO BIG SEVERE WEATHER ISSUES ARE EXPECTED WITH THIS ACTIVITY. THE THREATS FOR VERY HEAVY RAINFALL ARE TURNING OUT TO BE THE MAIN THREAT WITH THIS ACTIVITY. THE VERY WARM AND HUMID AIRMASS IS PRODUCING PWATS IN EXCESS OF 1.6 INCHES ACROSS THE AREA. ALTHOUGH THE STORMS HAVE BEEN FAIRLY PROGRESSIVE...THERE HAVE BEEN SEVERAL REPORTS OF 1 TO 1.5 INCH PER HOUR REPORTS OUT OF THIS ACTIVITY. IT APPEARS THAT AFTER THE TRAILING STRATIFORM PRECIPITATION PUSHES OUT OF THE AREA WITHIN THE NEXT COUPLE HOURS...THE CONVECTIVE THREAT WILL COME TO AN END...AT LEAST FOR THE NEXT FEW HOURS INTO THIS EVENING. THE OUTFLOW BOUNDARY...NOW PUSHING ACROSS MY FAR SOUTHERN COUNTIES...SHOULD WASH OUT AND LIFT BACK NORTHWARD THROUGH THE EVENING. THIS WILL ALLOW THE WARM AND HUMIDITY AIRMASS TO REBOUND NORTHWARD ACROSS THE AREA. THE MAIN BELT OF WESTERLIES REMAIN ACROSS THE PLAINS AND UPPER MIDWEST...WHERE ENHANCED MID LEVEL SOUTHWESTERLY FLOW RESIDES ALONG THE EASTERN PERIPHERY OF AN UPPER LOW/TROUGH ACROSS THE NORTHWESTERN CONUS. SEVERAL SMALLER SCALE PERTURBATIONS WITHIN THIS FLOW PATTERN CONTINUE TO SPARK OFF CONVECTION ACROSS THE DAKOTAS. THIS ACTIVITY SHOULD CONTINUE TO MOVE/DEVELOP EASTWARD INTO MINNESOTA THROUGH THIS EVENING. IT ALSO APPEARS THAT ADDITIONAL CONVECTION WILL DEVELOP SOUTHEASTWARD ACROSS WESTERN WISCONSIN AND POSSIBLY AS FAR SOUTH AS NORTHERN ILLINOIS LATER THIS EVENING AND OVERNIGHT AS ISENTROPIC ASCENT INCREASES ALONG THE NOSE OF A LOW LEVEL JET. IT APPEARS THE CHANCES WOULD BE NORTH OF THE AREA...BUT I FELL THAT SOME LOW END POPS ARE JUSTIFIED FOR AREAS NORTH OF INTERSTATE 80. THE MAIN THREAT FROM THESE STORMS WOULD BE VERY HEAVY RAINFALL. PWATS LOOK TO REMAIN IN EXCESS OF 1.6 INCHES THROUGH THE NIGHT...AND THE STEERING LAYER FLOW SUGGESTS THAT ANY STORMS THAT DEVELOP WILL BE SLOW MOVERS. HOWEVER...OVERALL CONFIDENCE ON THE STORMS REACHING AS FAR SOUTH AS NORTHERN ILLINOIS REMAIN LOW. BUT CONSIDERING THAT HEAVY RAINFALL OVER AN INCH OCCURRED ACROSS NORTHERN ILLINOIS TODAY...IF ANY MORE HEAVY RAINFALL OCCURS OVER THESE AREAS...THERE COULD BE SOME HYDRO ISSUES. SOME MORNING CONVECTION MAY CONTINUE ACROSS PORTIONS OF NORTHERN ILLINOIS EARLY SATURDAY MORNING. THERE WILL BE A THREAT FOR MORE WIDELY SCATTERED THUNDERSTORMS SATURDAY AFTERNOON...BUT WITH NO REAL LARGE SCALE FORCING MECHANISM...IT APPEARS THAT THE AERIAL COVERAGE SHOULD REMAIN FAIRLY LOW...AND THEREFORE I AM ONLY MENTIONING LOW END CHANCES. THE OTHER MAIN ISSUES WILL BE THE HEAT AND HUMIDITY THROUGH THE WEEKEND. TEMPERATURES WILL LIKELY TOP OUT NEAR OR JUST ABOVE THE 90 DEGREE MARK FOR THE NEXT FEW DAYS. AT THE SAME TIME...DEW POINTS WILL LIKELY BE NEAR 70...AND THIS SHOULD PRODUCE HEAT INDICES IN THE MID TO UPPER 90S. I WILL CONTINUE THE MENTION OF THESE HIGH HEAT INDICES IN THE HWO...BUT NO HEADLINES ARE PLANED AT THIS TIME. KJB LONG TERM...MON THROUGH FRI... 433 PM CDT WHILE ASTRONOMICAL SUMMER JUST BEGAN A DAY AND A HALF AGO...MID TO LATE SUMMER DOG-DAY TYPE CONDITIONS WILL BE THE RULE ACROSS THE REGION INTO THE LATTER PART OF NEXT WEEK. A PREVAILING W TO SW UPPER FLOW PATTERN WILL CONTINUE TO SPREAD THE VERY WARM AIR CURRENTLY OVER THE DESERT SW...CENTRAL ROCKIES AND CENTRAL HIGH PLAINS ACROSS THE NORTHERN AND CENTRAL PLAINS TO THE MIDWEST AND GREAT LAKES. THIS AIRMASS WILL BE SUBJECT TO COMPRESSIONAL HEATING AS THE PREVAILING FLOW MOVES THE CORE OF THE VERY WARM AIRMASS E OF THE ROCKIES. COUPLED WITH THE INCREASINGLY WARM AIR AND THE STAGNANT UPPER FLOW PATTERN A FAIRLY STRONG S TO SW LOWER LEVEL FLOW WILL PERSIST BETWEEN THE SPRAWLING HIGH CENTERED OVER WESTERN ATLANTIC AND THE LOW PRESSURE TROUGH TO BE VERY SLOWLY MOVING E ACROSS THE PLAINS. THIS WILL MAINTAIN A FEED OF VERY MOIST LOW LEVEL AIR FROM THE GULF OF MEXICO TO THE UPPER MIDWEST AND NORTHERN GREAT LAKES WITH DEW POINTS ACROSS THE FORECAST AREA BEING MAINTAINED IN THE UPPER 60S AND LOWER 70S. COMBINED WITH THE WARMING AIRMASS BRINGING HIGH TEMPERATURES UP TO THE UPPER 80S AND LOWER 90S THE HIGH DEW POINTS WILL CREATE HEAT INDEX VALUES PEAKING IN THE MIX AND UPPER 90S. AS THESE CONDITIONS LOOK TO CONTINUE INTO THE SECOND HALF OF THE WORK WEEK HEAT STRESS/EXCESSIVE HEAT MAY BECOME A PROBLEM AS OVERNIGHT LOWS WILL BE HELD UP IN THE LOWER AND MID 70S DUE TO THE HIGH DEW POINTS AND THIS WILL BE THE FIRST STRING OF MULTIPLE DAYS OF HOT AND HUMID WX. A LITTLE RELIEF WILL ARRIVE WITH A COOL FRONT PROGGED TO DROP ACROSS THE UPPER MIDWEST AND WESTERN GREAT LAKES WED NIGHT AND THU BUT THE VERY HUMID AIR WILL NOT BE SWEPT AWAY UNTIL A SECONDARY COOL FRONT PASSES ACROSS THE REGION THU NIGHT AND FRI. BESIDES THE HEAT AND HUMIDITY AS IT TYPICAL MULTIPLE SHORT WAVES/DISTURBANCES WILL BE MOVING ALONG WITH THE MEAN UPPER FLOW. THIS WILL TAKE THEM MAINLY FROM THE CENTRAL AND NORTHERN PLAINS ITO THE UPPER MIDWEST BUT THE LOCAL FORECAST AREA WILL BE UNDER PERIODIC CHANCES OF SHOWERS AND THUNDERSTORMS THROUGH THE WORK WEEK. TRS && .AVIATION... //ORD AND MDW CONCERNS...UPDATED 06Z... * POSSIBLE THUNDERSTORMS ARRIVING ARND 8Z THRU 11Z. * THUNDERSTORMS MAY DEVELOP LATER TODAY...WITH MINIMAL COVERAGE. * SOUTH WINDS ARND 10KT...THEN GUSTS DEVELOPING LATE THIS MORNING THROUGH EARLY THIS EVENING TO 20-24KT. BEACHLER //DISCUSSION...UPDATED 06Z... CHALLENGEING AVIATION CONDITIONS OVER THE NEXT 6-9 HOURS. A LINE OF THUNDERSTORMS WAS DEVELOPING ACROSS SOUTHERN WISCONSIN...WITH SOME INDICATIONS THAT THIS LINE WAS BEGINNING TO SLIDE SOUTHEAST INTO NORTHERN ILLINOIS. HI-RES GUIDANCE INDICATES THAT A CLUSTER OF SHOWERS/THUNDERSTORMS WOULD SLIDE SOUTHEAST TOWARDS ORD/MDW ARND 8-9Z AND CONTINUE TO PROGRESS SOUTHEAST TO GYY. AT THIS TIME THIS IS FAIRLY GOOD HANDLE ON CURRENT CONDITIONS...AND WILL SIDE WITH THIS THINKING. THUS IT APPEARS THE BACK EDGE OF THE THUNDERSTORMS WOULD CLEAR RFD ARND 10Z...ORD/MDW ARND 11Z. SOME LINGERING SHRA MAY OCCUR...BUT A STEADY DRYING TREND IS EXPECTED. OVERALL EXPECT CIGS TO REMAIN VFR...HOWEVER IF THE TSRA ARE STRONGER THEN CIGS COULD BRIEFLY DROP TO MVFR CONDS AS WELL AS VSBYS FROM BRIEF DOWNPOURS. ANOTHER COMPLICATION FOR LATER THIS MORNING WILL BE A LINE OF THUNDERSTORMS THAT WAS SLIDING EAST ACROSS NEBRASKA. AT THIS TIME FEEL HIGHER CONFIDENCE THAT THIS WILL NOT ARRIVE OR AT LEAST WILL NOT HAVE ANY DIRECT IMPACT ON THE TAF SITES. SOUTHERLY WINDS WILL DOMINATE THE DAY...WITH SOME TURNING TO THE SOUTHWEST AT 190-210 DEG RANGE. IN ADDITION IT APPEARS THAT GUSTS COULD EASILY TOUCH 20-22KT THIS AFTN...THE LARGEST CHALLENGE HERE IS THAT WITH THE POTENTIAL FOR A CIRRUS SHIELD OVERHEAD THAT WIND GUSTS MAY NOT BE AS STRONG. AT THIS TIME HAVE OPTED TO LEAVE IN THE GUSTS. AFTERNOON CONVECTION IS ALSO POSSIBLE AGAIN TODAY...HOWEVER TRYING TO DETERMINE THE LOCATION/TIMING/COVERAGE IS A CHALLENGE. AT THIS TIME HAVE HELD ONTO A DRY TAF FOR THIS AFTN/EVE...BUT IF CONVECTION DOES DEVELOP THIS WILL NEED TO BE ADJUSTED TO REFLECT. BEACHLER //ORD AND MDW CONFIDENCE...UPDATED 06Z... * HIGH CONFIDENCE IN WIND DIR/SPEED...MEDIUM CONFIDENCE IN GUSTS. * MEDIUM CONFIDENCE IN TSRA ARRIVAL TIME. * LOW CONFIDENCE IN DURATION OF TSRA. * LOW/MEDIUM CONFIDENCE IN REDEVELOPMENT OF TSRA AND COVERAGE.

THIS PREVAILING S TO SW WIND WILL CONTINUE TO SPREAD VERY WARM AND MOIST AIR ACROSS THE REGION TONIGHT...AND MAINTAIN IT THROUGH THE WEEKEND AND INTO NEXT WEEK. AS THIS WARM MOIST AIR MOVES OUT OVER THE COOL OPEN WATERS OF LAKE MI FOG WILL FORM AND MAY BECOME DENSE AT TIMES. DISTURBANCES MOVING E FROM THE NORTHERN PLAINS AND ACROSS THE UPPER GREAT LAKES DURING THE NEXT SEVERAL DAYS WILL MAINTAIN PERIODIC CHANCES FOR SHOWERS AND THUNDERSTORMS.

PERIODIC CHANCES FOR THUNDERSTORMS. THE MORE LIKELY LOCATIONS TO
SEE THUNDERSTORMS WILL BE ADJACENT TO THE WISCONSIN BORDER. IF
ANY THUNDERSTORMS DO OCCUR...THE POTENTIAL EXISTS FOR HEAVY RAIN
AND DAMAGING WINDS.
AN EXTENDED PERIOD OF VERY WARM AND HUMID CONDITIONS IS EXPECTED
FROM SATURDAY THROUGH WEDNESDAY WITH HEAT INDICES IN THE MIDDLE
