The episode as NWS LOT wrote it up.
Scattered thunderstorms, including a few supercells, moved across northwest Indiana producing large hail and at least one brief tornado.
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 Jul 13, 5:58 PM CST, 47 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
658 PM CDT MON JUL 13 2015
.MESOSCALE DISCUSSION...
658 PM CDT
LATEST RADAR TRENDS ARE SHOWING A SLIGHT NORTHWARD EXPANSION ON
THE MORE INTENSE THUNDERSTORM DEVELOPMENT. ALTHOUGH STRONGEST
THUNDERSTORM DEVELOPMENT WILL LIKELY CONTINUE TO BE ALONG AND
SOUTH OF I80...ISOLATED DEVELOPMENT BETWEEN THE I80 AND I88
CORRIDOR WILL BECOME INCREASINGLY MORE LIKELY OVER THE NEXT HOUR.
LARGE HAIL AND HEAVY RAINFALL WILL CONTINUE TO BE THE MAIN
HAZARDS...BUT DISCRETE STORMS DEVELOPING WITHIN HIGH 0-1 HELICITY
ENVIRONMENT WILL CONTINUE TO POSE A TORNADO THREAT. ALSO AM
MONITORING THUNDERSTORMS CURRENTLY DROPPING SOUTHEAST ACROSS
SOUTHERN WISCONSIN...WHICH ARE SEVERE AT THIS TIME. SEE NO REASON
WHY THESE WONT CONTINUE SOUTHEAST OVER THE NEXT SEVERAL HOURS AND
DISTANCE SPEED TOOL BRINGS THESE STORMS TO THE ILLINOIS/WISCONSIN
BORDER AROUND 8 PM CDT...AND THE CHICAGO AREA IN THE 9 TO 10 PM
CDT TIME FRAME. WITH PLENTY OF MOISTURE AND INSTABILITY
PRESENT...THESE STORMS WILL LIKELY MAINTAIN SIMILAR INTENSITY AS
THEY MOVE TOWARDS THE CWA.
&&
.SHORT TERM...
332 PM CDT
LATE TONIGHT THROUGH TUESDAY...
BULK OF THUNDERSTORM ACTIVITY WILL EXIT DURING THE REMAINING
OVERNIGHT HOURS...HOWEVER...BROAD CYCLONIC FLOW USHERING IN A
STEADY STREAM OF SHORTWAVE ENERGY COULD ALLOW FOR ADDITIONAL
ISOLATED TO SCATTERED DEVELOPMENT THROUGH EARLY TUESDAY MORNING.
COVERAGE WILL LIKELY BE LOW...AND SO HAVE ONLY MAINTAINED SLIGHT
CHANCE TO LOW CHANCE POPS. FRONT WILL PUSH THROUGH THE AREA
THROUGH TUESDAY MORNING...BUT DONT THINK LOW LEVEL MOISTURE WILL
SCOUR TOO MUCH. GUIDANCE IN FAIR AGREEMENT WITH LOWER 70S
DEWPOINTS STILL LINGERING ACROSS THE CWA THROUGH TUESDAY. WITH
MODERATE INSTABILITY REMAINING PRESENT OVER THE CWA AND WITH
ADDITIONAL SURFACE FOCUS OWING TO SOUTHWARD MOVING SURFACE
TROUGH/BOUNDARY...THINK SCATTERED THUNDERSTORM DEVELOPMENT WILL
ONCE AGAIN BE POSSIBLE BY EARLY TUESDAY AFTERNOON. FLOW ALOFT
REMAINS SUFFICIENT FOR MODERATE BULK SHEAR VALUES TO BE IN
PLACE...AND WITH ALL OF THE FEATURES...DO THINK THAT THERE IS AT
LEAST A DECENT POSSIBILITY FOR ADDITIONAL STRONG STORMS DURING
THIS TIME.
RODRIGUEZ
&&
.LONG TERM...
240 PM CDT
TUESDAY NIGHT THROUGH MONDAY...
AN UPPER TROUGH AXIS WILL BE CLEARING THE AREA TUESDAY EVENING
WHILE UPPER RIDGING AMPLIFIES INTO THE NORTHERN PLAINS. SURFACE
HIGH PRESSURE WILL SPREAD SOUTHEASTWARD INTO THE GREAT LAKES. THIS
WILL BRING A COOL DOWN ALONG WITH NORTHEASTERLY LOW LEVEL FLOW. SO
WHILE INLAND AREAS WILL WARM TO THE UPPER 70S TO NEAR 80 LAKESHORE
AREAS WILL BE HELD TO THE LOWER 70S WEDNESDAY. THE SURFACE HIGH
WILL SHIFT EAST WEDNESDAY NIGHT WHILE THE UPPER RIDGE AXIS IS
SHUNTED EASTWARD OVER THE LOCAL AREA BY AN UPPER TROUGH MOVING
ACROSS THE MID/UPPER MISSISSIPPI RIVER VALLEY. THIS WILL RESULT IN
A PUSH OF WARM ADVECTION AND A STEADIER SOUTHERLY LOW LEVEL FLOW
FOR THURSDAY WHICH WILL MEAN WARMER TEMPS. THE BEST FORCING LOOKS
TO BE NORTH OF THE AREA AHEAD OF THE UPPER TROUGH BUT WAA WILL
PROBABLY BE STRONG ENOUGH TO BRING SOME SHOWER AND THUNDERSTORM
ACTIVITY FROM WEST TO EAST ACROSS THE AREA THURSDAY. THE UPPER
FLOW WILL BE DE-AMPLIFYING AS IT PASSES BUT SEVERAL SHORTWAVES
LOOK TO MOVE THROUGH THE FLOW AND A SURFACE LOW IS EXPECTED TO
MOVE NEAR/NORTH OF THE AREA THURSDAY NIGHT. THIS WILL KEEP DECENT
CHANCES FOR SHOWERS AND STORMS IN THE FORECAST. THE LOW WEAKENS AS
IT MOVES NORTHEAST AND ITS ATTENDANT FRONT WASHES OUT TO SOME
EXTENT SO WARMTH WILL CONTINUE TO BUILD ON SOUTHWEST WINDS. SOME
PRECIP COULD LINGER FRIDAY MORNING BUT IT DOES APPEAR DRY
CONDITIONS WILL RETURN FOR AT LEAST A SHORT TIME LATER IN THE DAY
AND FRIDAY NIGHT. ANOTHER UPPER RIDGE AMPLIFIES INTO THE AREA
SATURDAY SO WARM AND HUMID CONDITIONS WILL CONTINUE WITH A PARADE
OF SHORTWAVES BRINGING PERIODIC THUNDERSTORM CHANCES THROUGH THE
WEEKEND. SATURDAY LOOKS TO BE THE WARMEST DAY WHERE SOME AREAS
COULD REACH 90..ESPECIALLY SOUTH AND WEST...BEFORE TEMPS MODERATE
SLIGHTLY SUNDAY.

.AVIATION...
//ORD AND MDW CONCERNS...UPDATED 00Z...
* MAIN CONCERN IN THE NEAR TERM IS THE CONTINUED EXPANSION...VERY
SLOWLY SO FAR...OF TSRA ACTIVITY NORTHEAST INTO TERMINAL AREA
THIS EVENING. ADDITIONAL BUT WEAKER TSRA IS POSSIBLE TOMORROW.
LENNING
//DISCUSSION...UPDATED 00Z...
DUE TO A WEAK BUT APPARENTLY SUFFICIENT CAPPING LAYER AND THE
LACK OF LOW LEVEL CONVERGENCE TO TRIGGER WIDESPREAD NEW STORM
DEVELOPMENT SO FAR TODAY...THE VERY UNSTABLE AIRMASS IN PLACE OVER
THE AREA HAS BEEN QUITE EFFECTIVE AT SUPPORTING VERTICAL
DEVELOPMENT SOUTHWEST OF THE TERMINALS BUT VERY SLOW TO EXPAND THE
ACTIVITY HORIZONTALLY. THUS ORD/MDW HAVE STAYED DRY MUCH LONGER
THAN WAS ANTICIPATED. GIVEN THESE TRENDS...RATHER THAN PULLING
CONVECTION ALTOGETHER...HAVE CONTINUED TO PUSH BACK THE
TIMING...NOW INTO THE 02-04Z PERIOD.
ONCE...OR IF...ACTIVITY DOES MOVE THROUGH...THE REMAINDER OF THE
NIGHT SHOULD BE QUIET. TOMORROW MAY SEE ANOTHER ROUND OF SHRA/TSRA
TOWARD LATE MORNING OR INTO THE AFTERNOON BEFORE THE SUPPORTING
WAVE OF ENERGY ALOFT MOVES THROUGH THE AREA. NORTHEAST WINDS THEN
TURN OFF THE LAKE LATE.
LENNING
//ORD AND MDW CONFIDENCE...UPDATED 00Z...
* JUST LOW TO MEDIUM CONFIDENCE ON TSRA TRENDS THIS EVENING.
* MEDIUM CONFIDENCE ON TIMING AND EXTENT OF TSRA TOMORROW.
LENNING
//OUTLOOK FOR ORD/MDW FOR 12Z WEDNESDAY-12Z MONDAY...UPDATED 00Z...
WEDNESDAY AND THURSDAY...PRIMARILY VFR.
THURSDAY NIGHT AND FRIDAY...SHRA/TSRA POSSIBLE.
SATURDAY...VFR LIKELY.
SUNDAY...SHRA POSSIBLE. VFR LIKELY.
LENNING
&&
.MARINE...
349 PM CDT
SOUTHERLY WINDS OF 10 TO 20 KT CONTINUE ACROSS THE LAKE THIS
AFTERNOON...AS LOW PRESSURE REMAINS JUST TO THE WEST/NORTHWEST.
EXPECT THIS SOUTHERLY FLOW TO PERSIST FOR A PORTION OF THIS
EVENING/TONIGHT UNTIL WINDS SHIFT TO THE NORTH...AS THIS LOW AND
ASSOCIATED FRONTAL BOUNDARY MOVE THROUGH THE REGION. THESE
NORTHERLY WINDS WILL INCREASE ON TUESDAY...WITH NORTH WINDS OF 15
TO 25 KT AND THEN TO 30 KT LIKELY BY THE AFTERNOON AND EARLY
EVENING. WAVES WILL BUILD THROUGH THIS PERIOD AND THINK HAZARDOUS
CONDITIONS FOR SMALL CRAFT WILL OCCUR FOR BOTH THE ILLINOIS AND
INDIANA NEARSHORE WATERS BY EARLY TUESDAY EVENING.

TORNADOES...INCLUDING A STRONG TORNADO OR TWO.
TORRENTIAL DOWNPOURS AND FLASH FLOODING.
AREAS AFFECTED AND TIMING:
THROUGH LATE THIS EVENING ACROSS THE OUTLOOK AREA.
DISCUSSION:
A VERY MOIST AND UNSTABLE ENVIRONMENT WILL ALLOW EXPLOSIVE

ANY DISCRETE STORM COULD PRODUCE A STRONG TORNADO OR TWO...AND
LARGE TO VERY LARGE HAIL WILL ALSO BE POSSIBLE. IF EVOLUTION TO
ONE OR MORE FAST MOVING THUNDERSTORM COMPLEXES OCCURS...THEN THE

WINDS...WITH AN ISOLATED TORNADO AND HAIL THREAT. A VERY MOIST
AIRMASS WILL REMAIN IN PLACE THROUGH TONIGHT...SO ANY INTENSE
THUNDERSTORM WILL PRODUCE EXCESSIVE RAINFALL RATES AND THE
POTENTIAL FOR RAPID FLASH FLOODING.
PORTIONS OF THE ILLINOIS...IROQUOIS...VERMILLION AND KANKAKEE
RIVERS...AND SUGAR CREEK ARE IN FLOOD....WITH RENEWED RISES
POSSIBLE DUE TO ANY HEAVY RAIN TONIGHT.
