The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Lincoln, IL (KILX), launched 00:00Z, 3.0 hours before the alert went out and 190 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Sep 18, 9:53 PM EDT, 1 hour 7 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
953 PM EDT FRI SEP 18 2015

.UPDATE...
NEAR TERM SECTION FOR THE REST OF TONIGHT HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...
ISSUED AT 321 PM EDT FRI SEP 18 2015

RAIN AND THUNDERSTORMS WILL IMPACT CENTRAL INDIANA THROUGH EARLY
SATURDAY AFTERNOON AS A COLD FRONT TRACKS THROUGH THE REGION. HIGH
PRESSURE WILL THEN BUILD IN AND DOMINATE WEATHER ACROSS THE OHIO
VALLEY THROUGH MUCH OF NEXT WEEK. COOL TEMPERATURES SUNDAY AND
MONDAY WILL SLOWLY WARM THROUGHOUT THE WEEK.

&&

.NEAR TERM /REST OF TONIGHT/...
ISSUED AT 953 PM EDT FRI SEP 18 2015

.UPDATE...THUNDERSTORMS HAVE REMAINED JUST NORTHWEST OF OUR FORECAST AREA
THIS EVENING...BUT THUNDERSTORM SHOULD GRADUALLY OVERSPREAD AT LEAST THE
NORTHWEST HALF OF OUR AREA PER RADAR TREND AND HRR MODEL.  HAVE BACKED
OFF POPS A LITTLE ALL BUT FAR NORTHWEST THROUGH 06Z AND THEN RAISED POPS
SLIGHTLY MOST AREA VERY LATE TONIGHT.  RAISED TEMPERATURE A DEGREE OR
TWO MOST AREAS AS COLD FRONT WILL ONLY BE ENTERING OUR NORTHWEST BY 12Z.
REST OF NEAR TERM LOOKS OK.

PORTION OF PREVIOUS NEAR TERM DISCUSSION FOLLOWS...
BETTER THREAT FOR MORE WIDESPREAD CONVECTION WILL ARRIVE AFTER
MIDNIGHT AS THE FRONT PROGRESSES INTO THE REGION IN RESPONSE TO THE
PASSAGE OF THE AFOREMENTIONED LOW PRESSURE. NICE LOW LEVEL JETLET
WILL ACCOMPANY THE SURFACE WAVE TRACK INTO THE LOWER GREAT LAKES AND
SHOULD SERVE TO ENHANCE PRECIP COVERAGE OVER NORTHWEST COUNTIES
OVERNIGHT. COULD SEE STRONG STORMS OVERNIGHT IN NORTHERN FORECAST
AREA BUT GENERALLY EXPECT ANY STORMS REMAIN SUBSEVERE. WILL CARRY
HIGHEST POPS IN THE NORTHERN WABASH VALLEY WITH LOWER CHANCE POPS
FURTHER SOUTH AND EAST. BESIDE A LESS FAVORABLE AIRMASS FURTHER
SOUTHEAST ACROSS THE FORECAST AREA... SPLITTING JETS ALOFT MAY
FURTHER LIMIT PRECIP COVERAGE AND INTENSITY IN THE PREDAWN HOURS.

TEMPS...TRENDED TOWARDS WARMER METMOS GUIDANCE AS CLOUDS AND PRECIP
WILL KEEP LOWS MAINLY IN THE MID AND UPPER 60S. POTENTIAL FOR LOWS
TO FALL TO NEAR 60 IN THE NORTHWEST AS THE FRONT SHOULD PASS PRIOR
TO DAYBREAK.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY/...
ISSUED AT 321 PM EDT FRI SEP 18 2015

FORECAST CHALLENGES FOCUS ON PRECIP CHANCES SATURDAY AND TEMPS
THROUGHOUT THE SHORT TERM.

COLD FRONT WILL BE ACROSS THE FORECAST AREA ON SATURDAY MORNING...
AND WILL CONTINUE ITS EASTWARD PROGRESSION AS THE SURFACE LOW
STRENGTHENS AS IT TRACKS INTO ONTARIO. 12Z NAM HAS BECOME A SLOW
OUTLIER WITH BULK OF THE MODEL CONSENSUS SHIFTING THE FRONTAL
BOUNDARY EAST OF THE FORECAST AREA BY EARLY AFTERNOON WITH RAIN
CHANCES ENDING SHORTLY THEREAFTER. MODEL SOUNDINGS AND HI-RES
GUIDANCE CONTINUES TO HINT AT SOME INSTABILITY IMMEDIATELY ALONG AND
AHEAD OF THE FRONT THAT WILL WARRANT MAINTAINING A THUNDER MENTION
FOR A FEW HOURS. COULD SEE GUSTY WINDS WITH ANY STRONGER STORMS
EARLY ON...MAINLY NEAR THE TAIL END OF THE DEPARTING LOW LEVEL JET
OVER NORTHERN COUNTIES. THREAT FOR ANY THUNDER THOUGH SHOULD BE GONE
BY MIDDAY WITH THE ENTIRE FORECAST AREA PRECIP FREE AROUND OR
SHORTLY AFTER 18Z. EXPECT GUSTY NORTHERLY FLOW ON SATURDAY AS WELL.

SKIES ARE LIKELY TO CLEAR RAPIDLY IN WAKE OF THE FRONTAL BOUNDARY AS
STRONG HIGH PRESSURE BUILDS IN FROM THE NORTHWEST. THE HIGH WILL
BECOME THE PRIMARY INFLUENCE ON WEATHER ACROSS THE REGION THROUGH
THE REMAINDER OF THE SHORT TERM AS IT TRACKS EAST INTO NEW ENGLAND
BY LATE MONDAY. DRY COOL E/NE FLOW WILL DEVELOP ACROSS CENTRAL
INDIANA WITH TRANQUIL WEATHER AND COMFORTABLE TEMPS FOR SUNDAY AND
MONDAY. DESPITE SUBSIDENCE THROUGH THE COLUMN REGION WILL REMAIN
UNDER THE 850MB COLD POOL WHICH SHOULD BE SUFFICIENT TO GENERATE
DIURNAL CU...ESPECIALLY SUNDAY. EXPECT SOME WIND GUSTS TO AROUND
20MPH BOTH AFTERNOONS WITH A PERSISTENT  SURFACE PRESSURE GRADIENT.
REALLY NICE STRETCH OF TYPICAL PLEASANT LATE SEPTEMBER WEATHER SET
TO MAKE AN APPEARANCE.

TEMPS...LATE DAY SUN ON SATURDAY SHOULD ALLOW FOR SOME TEMP RECOVERY
WITH LOW LEVEL THERMALS GENERALLY SUPPORTING MID 70S FOR HIGHS. HARD
TO ARGUE WITH A MOS BLEND FOR SUNDAY AND MONDAY WITH COMFORTABLE
TEMPS IN THE LOWER TO MID 70S. LARGELY LEANED TOWARDS COOLER MET
GUIDANCE FOR LOWS THROUGH THE PERIOD. EXPECT LOWS BACK INTO THE 40S
SATURDAY AND SUNDAY NIGHTS...WITH LIKELY SOME MID 40S IN EASTERN
COUNTIES SUNDAY NIGHT.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
ISSUED AT 321 PM EDT FRI SEP 18 2015

ENSEMBLES IN GENERAL AGREEMENT IN AN UPPER RIDGE REESTABLISHING ITSELF
ACROSS THE MIDWEST BY THE MIDDLE OF NEXT WEEK AS A CUTOFF UPPER LOW
DEVELOPS OVER THE EAST COAST.

ENSEMBLES ARE MAINLY DRY FOR THE BALANCE OF THE LONG TERM. THERE ARE
A FEW MEMBERS THAT SUGGEST AN UPPER TROUGH MAY SCOOT THROUGH THE GREAT
LAKES LATE NEXT WEEK...WITH AN ATTENDANT FRONT AND PRECIPITATION THREAT.
HOWEVER...THE SIGNAL IS NOT STRONG ENOUGH TO CHANGE THE FORECAST AT THIS
TIME. WILL CONTINUE WITH A DRY EXTENDED.

.AVIATION /DISCUSSION FOR THE 19/00Z TAFS/...
ISSUED AT 721 PM EDT FRI SEP 18 2015

MAINLY VFR THROUGH THE FIRST 9-15 HOURS OF THE PERIOD...WITH MVFR
POSSIBLE IN SHOWERS/THUNDER LATE TONIGHT AND IN THE WAKE OF COLD
FRONTAL PASSAGE TOMORROW MORNING.

CONCERNS REMAIN ABOUT COVERAGE OF STORMS LATE TONIGHT AND WILL
