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 21, 6:59 PM CST, 1 hour 21 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 759 PM CDT MON JUN 21 2010 .MESOSCALE DISCUSSION... 134 PM CDT THIS MORNING'S MCV CONTINUES TO MOVE EASTWARD EARLY THIS AFTERNOON WITH SKIES CLEARING OUT AND ATMOSPHERE GRADUALLY RECOVERING. SPC OBJECTIVE ANALYSIS DATA...VISIBLE SATELLITE IMAGERY...AND RECENT ACARS SOUNDINGS SUGGEST THAT THE ATMOSPHERE HAS NOT YET RECOVERED FROM THE MORNING CONVECTION WITH CONSIDERABLE CIN FOR BOUNDARY LAYER BASED CONVECTION. TEMPERATURES ARE WARMING QUICKLY AND THE RECOVERY PROCESS IS WELL UNDERWAY OVER SOUTHERN PORTIONS OF THE CWA...CIN FOR BOUNDARY LAYER BASED PARCELS SOUTH OF THE KANKAKEE RIVER LIKELY TO BE NEGLIGIBLE SOON. STRONG...LIKELY SLIGHTLY ELEVATED STILL...CONVECTION FROM PIA SOUTHWESTWARD WILL LIKELY INTENSIFY FURTHER AS IT PUSHES EASTWARD THIS AFTERNOON. VERY HIGH REFLECTIVITY/LOW CENTROID STORMS ARE LIKELY EXTREMELY EFFICIENT RAIN PRODUCERS WITH FAIRLY LOW HAIL THREAT GIVEN WARM/MOIST ENVIRONMENT. DCAPE VALUES ARE SUFFICIENT FOR STORMS TO BEGIN TO FORM A COLD POOL AND ACCELERATE EASTWARD WITH AN INCREASING THREAT FOR DAMAGING WINDS AS THE AFTERNOON WEARS ON. IT IS UNCLEAR WHETHER THE ATMOSPHERE OVER THE CENTRAL AND NORTHERN PORTIONS OF THE CWA WILL HAVE TIME TO RECOVER SUFFICIENTLY FOR STRONG/SEVERE STORMS TO DEVELOP IN ASSOCIATION WITH ACTIVITY CURRENTLY OVER EASTERN IA. CONFIDENCE IS LOWER ON THIS SCENARIO AND IT WILL CERTAINLY BARE WATCHING AS THE AFTERNOON WEARS ON. IZZI && .DISCUSSION... 246 PM CDT SHORT TERM (TONIGHT THROUGH THURSDAY)... FORECAST REASONING HAS CHANGED VERY LITTLE FROM PREVIOUS COUPLE OF AFD'S WITH RING OF FIRE PATTERN CONTINUING. MCV MOVING TOWARD THE AREA THIS AFTERNOON WILL LIKELY CONTINUE TO LIGHT UP THIS AFTERNOON WITH CONVECTION BECOMING MORE ORGANIZED AND CONGEALING INTO ANOTHER MCS THAT SHOULD BE EXITING THE CWA EARLY THIS EVENING. WATER VAPOR IMAGERY WOULD THEN SUGGEST WE COULD SEE A RATHER SIZABLE BREAK IN THE PRECIPITATION AWAITING THE NEXT MCS TO ORGANIZE OVER THE PLAINS AND PEEL EASTWARD...WHICH MAY BE DELAYED UNTIL SOMETIME TUESDAY IF MODEL GUIDANCE IS ANYWHERE NEAR CORRECT. WILL LIKELY MAKE SOME LAST MINUTE TWEAKS TO POP/WX GRIDS BASED ON NEAR TERM TRENDS BUT THINKING THAT WE MAY BE ABLE TO LOWER POPS CONSIDERABLY OVERNIGHT. ASSUMING THAT TONIGHT'S MCS OVER THE PLAINS DOESNT ARRIVE UNTIL THE AFTERNOON ON TUESDAY...THEN IT IS LIKELY THAT THE FRONT WILL HAVE HAD TIME TO MEANDER FARTHER NORTHWARD AND IN ALL LIKELIHOOD WE SHOULD BECOME MODERATELY TO STRONGLY UNSTABLE. REGENERATION OF CONVECTION WOULD THEN BE LIKELY QUITE LIKELY WITH AN ENHANCED THREAT OF DAMAGING WINDS TUESDAY AFTERNOON. THIS ALL HINGES OF COURSE ON THE TIMING OF THE MCS TONIGHT INTO TUESDAY WHICH WE (AND THE MODELS) REALLY HAVE VERY LITTLE SKILL IN FORECASTING. WAVE TRAIN OF MCS'S SHOULD CONTINUE TUESDAY NIGHT THROUGH WEDNESDAY NIGHT WITH ANOTHER COUPLE OF MCS'S PROBABLE DURING THAT TIME PERIOD. THESE THUNDERSTORMS WILL BE VERY EFFICIENT RAIN PRODUCERS AS WE FOUND OUT THIS MORNING WITH THE SWATH OF LOCALLY 3" OF RAIN IN OUR SOUTHERN CWA. NO REASON FOR RAINFALL OF AT LEAST THAT MAGNITUDE TO NOT OCCUR AGAIN A COUPLE MORE TIMES OVER THE NEXT COUPLE OF DAYS. GAVE VERY SERIOUS CONSIDERATION TO A FLASH FLOOD WATCH WITH THIS AFTERNOON'S FORECAST. HOWEVER FOR THE MOST PART WE MISSED SIGNIFICANT RAINFALL TOTALS WITH THIS MORNING'S MCS (EXCEPT FAR SOUTH) AND SINCE IT APPEARS THAT ANY FLOOD THREAT WOULD BE ISOLATED WITH THIS AFTERNOON/EVENING'S CONVECTION...INCLUDING A BREAK FOLLOWING. THERE AFTER I DECIDED TO HOLD OFF ON HEADLINES FOR NOW AND WILL RE-ISSUE THE ESF. STILL WOULD THINK THAT AT SOME POINT IN THE NOT TOO DISTANT FUTURE...WE WILL NEED A FLASH FLOOD WATCH. SHOULD THE WARM FRONT MAKE IT SOLIDLY NORTH AND WE NOT SIT UNDER CONVECTIVE DEBRIS OR OUTFLOW TUESDAY OR WEDNESDAY THEN IT WOULD LIKELY GET VERY HOT AND HUMID. COULD EVEN FLIRT WITH HEAT ADVISORY CRITERIA IN OUR SOUTHERN COUNTIES...HOWEVER WITH OUR AREA SEEMINGLY LOCKED ON THE MCS TRAIN TRACKS ITD BE SILLY TO EVEN PONDER THOSE KIND OF HEADLINES FOR 2ND PERIOD. CANADIAN HIGH SHOULD FINALLY BUILD SOUTHEASTWARD INTO THE REGION THURSDAY WITH MUCH DRIER AIRMASS USHERING INTO THE REGION AND FIRMLY CLAMPING OFF THE SPICKET IN THE SKY FOR A COUPLE DAYS AT LEAST. IZZI LONG TERM (FRIDAY THROUGH MONDAY)... RELATIVELY DRY END TO THE WEEK WILL SHIFT BACK TOWARDS WET THIS WEEKEND. HIGH PRESSURE WILL SHIFT EAST FROM THE PLAINS AND ACROSS THE GREAT LAKES BY FRIDAY MORNING BEFORE SHIFTING EAST ACROSS NEW ENGLAND BY THE START OF THE WEEKEND. A WARM FRONT SHOULD LIFT THROUGH EARLY IN THE WEEKEND ALLOWING FOR SOME OF THE HOTTEST TEMPERATURES OF THE YEAR TO TAKE HOLD. ENSEMBLE GUIDANCE IS SUGGESTING H85 TEMPERATURES AROUND 21-22 DEGREES C SATURDAY AFTERNOON OVER THE CHICAGO METRO...AND SIMILAR CONDITIONS SUNDAY. WINDS WILL BECOME SOUTHERLY AS THE FRONT PUSHES NORTH...BRINGING BACK MOISTURE FROM THE SOUTH. WHILE STILL EARLY...IT IS WORTH NOTING THAT HEAT INDICIES COULD EASILY FLIRT WITH 100S IF THIS PANS OUT. SOUTH TO SOUTHWEST WINDS IN THE OVERNIGHT HOURS DURING THE WEEKEND WILL LEAVE LITTLE IN RELIEF OVERNIGHT IN THE METRO AREA WHERE THE HEAT ISLAND WILL EFFECT WILL DOMINATE. ENSEMBLE RELATIVE MEASURE OF PREDICTABILITY FALLS OFF BEYOND MONDAY AS FLOW BECOMES ZONAL AND ENSEMBLE SPREAD BECOMES QUITE LARGE. SHEA && .AVIATION... //ORD AND MDW CONCERNS...UPDATED 01Z... LINE OF THUNDERSTORMS IS TRACKING SLOWER THAN ORIGINALLY PROJECTED...HAVE UPDATED TAFS TO REFLECT NEW TIMING. WILL HAVE TO CONTINUE TO MONITOR AS STORMS COULD ACCELERATE AS THEY CONTINUE TO EVOLVE. BMD //DISCUSSION...UPDATED 00Z... LINE OF STRONG THUNDERSTORMS HAS DEVELOPED ALONG AN OUTFLOW BOUNDARY EARLY THIS EVENING. AT 00Z...THIS LINE OF THUNDERSTORMS EXTENDS ALONG A NORTH SOUTH ORIENTED LINE ABOUT 30 MILES WEST OF KRFD THEN EXTENDS TO THE SOUTHWEST INTO IOWA AND NORTHERN MISSOURI. THE SOUTHERN SECTIONS OF THIS LINE OF THUNDERSTORMS CONTINUE TO MOVE INTO A FAVORABLE ENVIRONMENT FOR THUNDERSTORM DEVELOPMENT WHILE THE NORTHERN PORTIONS HAVE MAINTAINED INTENSITY OVER THE PAST COUPLE HOURS WHILE CONGEALING INTO A LINE. WINDS PREDOMINATELY OUT OF THE SOUTH EARLY IN THE PERIOD ARE EXPECTED TO TURN MORE SOUTH-SOUTHWEST TO SOUTHWESTERLY AS A WEAK SURFACE TROUGH TRAVERSES THE NORTHERN PART OF THE STATE THIS EVENING. WINDS SHOULD SUBSIDE AFTER 12Z AS SURFACE HIGH TRIES TO REESTABLISH ITSELF OVER MINNESOTA. EARLY AFTERNOON ON TUESDAY...WINDS SHOULD BECOME SOUTHERLY AGAIN AS A LOW PRESSURE SYSTEM INTENSIFIES OVER THE PLAIN STATES. BMD //ORD AND MDW CONFIDENCE...UPDATED 01Z...

456 PM CDT MON JUN 21 2010 /556 PM EDT MON JUN 21 2010/
THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.
.DAY ONE...TONIGHT.
WEATHER HAZARDS EXPECTED:
SCATTERED THUNDERSTORMS...SOME COULD PRODUCE:
DAMAGING WINDS IN EXCESS OF 70 MPH.
HAIL TO THE SIZE OF GOLFBALLS.
VERY HEAVY RAINFALL WITH LOCALIZED FLOODING.
FREQUENT CLOUD TO GROUND LIGHTNING.
POSSIBLY A TORNADO.
AREAS AFFECTED AND TIMING:
SCATTERED THUNDERSTORMS WILL DEVELOP EARLY THIS EVENING AND
COULD LINGER INTO THE EARLY PORTIONS OF THE OVERNIGHT
HOURS...WITH THE GREATEST POTENTIAL FOR SEVERE WEATHER SOUTH OF
A VALPARAISO TO JOLIET TO OREGON LINE.
DISCUSSION:
THE ATMOSPHERE IS QUICKLY DESTABILIZING AND WINDS ALOFT ARE
INCREASING IN ADVANCE OF AN APPROACHING UPPER LEVEL
DISTURBANCE...SETTING THE STAGE FOR THE DEVELOPING THUNDERSTORMS
TO QUICKLY BECOME SEVERE. GIVEN THE VERY STRONG INSTABILITY AND
INCREASING WINDS ALOFT THE POTENTIAL EXISTS FOR THE MOST INTENSE
STORMS TO PRODUCE DAMAGING WINDS...LARGE HAIL AND POSSIBLY A
TORNADO.
THE THREAT OF SEVERE THUNDERSTORMS SHOULD GRADUALLY DIMINISH
LATER THIS EVENING INTO THE OVERNIGHT HOURS. GIVEN THE VERY
MOIST AIRMASS IN PLACE THE POTENTIAL WILL EXIST FOR LOCALLY
HEAVY RAINFALL...WHICH COULD RESULT IN LOCALIZED FLASH FLOODING.
FINALLY...PORTIONS OF THE UPPER ILLINOIS RIVER AND SUGAR CREEK
WILL REMAIN IN FLOOD.
.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
THE AREA WILL CONTINUE TO SEE PERIODIC THUNDERSTORMS TUESDAY
THROUGH WEDNESDAY NIGHT. WE WILL REMAIN IN A PATTERN THAT IS
CONDUCIVE FOR SOME OF THESE THUNDERSTORMS TO BE SEVERE WITH
DAMAGING WINDS THE PRIMARY THREAT.
THE THUNDERSTORMS WILL ALSO PRODUCE LOCALLY VERY HEAVY RAINFALL
TOTALS...WITH THE THREAT OF FLASH FLOODING INCREASING WITH EACH
SUCCESSIVE ROUND OF THUNDERSTORMS. GIVEN THE POTENTIAL FOR
REPEATED BOUTS OF HEAVY RAINFALL...THE THREAT DOES EXIST FOR
SIGNIFICANT FLOODING PROBLEMS TO DEVELOP THIS WEEK.
PORTIONS OF THE UPPER ILLINOIS RIVER WILL REMAIN IN FLOOD
THROUGH THE UPCOMING WORK WEEK.
HEAT INDICES OVER 100 DEGREES ARE POSSIBLE OVER THE WEEKEND.
THERE IS ALSO A CHANCE OF THUNDERSTORMS BY SATURDAY NIGHT INTO
SUNDAY.
.SPOTTER INFORMATION STATEMENT...
SPOTTERS WILL BE NEEDED THIS EVENING.
