The radar

The Indianapolis radar (KIND), 85 km from the middle of the area, began a volume at 22:14 UTC, the scan nearest the moment this went out.

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

Cncnati-Daytn, OH (KILN), launched 12:00Z, 10.2 hours before the alert went out and 135 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, Jul 20, 4:20 PM EDT, 1 hour 51 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
420 PM EDT WED JUL 20 2011

.UPDATE...

THE AVIATION SECTION HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...

DANGEROUSLY OPPRESSIVE HEAT AND HUMIDITY CONTINUES INTO THE
WEEKEND AS RIDGING ALOFT REMAINS IN PLACE. A WEAK BOUNDARY MAY
APPROACH THE AREA ON FRIDAY BEFORE WASHING OUT. ANOTHER WEAK
BOUNDARY AND SURFACE HIGH MAY ENTER THE AREA EARLY NEXT
WEEK...ALLOWING A SLIGHT COOL DOWN...BUT WITH TEMPERATURES STILL
REMAINING ABOVE NORMAL.

&&

.NEAR TERM /TONIGHT/...

FOCUS IS TEMPERATURES. GUIDANCE IS SIMILAR ON MAJOR FEATURES AND A
BLEND IS SUFFICIENT.

CONSIDERED A SLIGHT CHANCE POP FOR THE FIRST HOUR OR TWO OF THE
OVERNIGHT PERIOD TO ACCOUNT FOR ANY POP UPS THAT MANAGE TO HOLD ON
PAST 00Z...BUT FEEL THAT THIS IS UNLIKELY ENOUGH TO MERIT NO
MENTION. AMPLE INSTABILITY IS PRESENT...BUT WITH LITTLE TO NO
SHEAR AND FORCING/TRIGGERS...EXPECT VAST MAJORITY OF STORMS TO
HAVE DISSIPATED BY 00Z.

ON TEMPS...GUIDANCE PERFORMING POORLY ON OVERNIGHTS...ESPECIALLY
NEAR CITIES IN THE AREA...AND WITH NO AIRMASS CHANGE WILL GO WITH
TEMPS AT OR SLIGHTLY ABOVE PERSISTENCE.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...

FOCUS REMAINS TEMPS. GUIDANCE IS SIMILAR AND A BLEND IS SUFFICIENT.

LITTLE CHANGE IN AIRMASS ANTICIPATED THROUGH THE END OF THE WORK
WEEK...AND THUS HEAT AND HUMIDITY WILL CONTINUE. GUIDANCE
STRUGGLES WITH THIS...AND TEMPS AT OR ABOVE PERSISTENCE WILL BE
USED TOMORROW...WITH A SLIGHT REDUCTION ON FRIDAY FOR ADDITIONAL
THUNDERSTORM POTENTIAL.

AMPLE INSTABILITY NECESSITATES A SLIGHT CHANCE POP TOMORROW
AFTERNOON...BUT CANNOT JUSTIFY HIGHER IN ABSENCE OF SIGNIFICANT
FORCING. A WEAK BOUNDARY MAY APPROACH THE AREA...BUT WILL LIKELY
STALL WELL TO THE NORTH ON THURSDAY. THIS BOUNDARY MAY GET A
LITTLE CLOSER ON FRIDAY...AND GUIDANCE HINTS AT WEAK WAVES THAT
MAY SLIDE ALONG THE BOUNDARY IN THE PRESENCE OF A SLIGHTLY
WEAKENING CAP. THUS...WILL CONTINUE SLIGHT CHANCE TO LOW CHANCE
POPS ON FRIDAY.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...

LITTLE RELIEF IN SIGHT AS FLAT...BROAD RIDGING REMAINS THE RULE
ACROSS THE REGION. WEAK BOUNDARY AND SURFACE HIGH EARLY NEXT WEEK
WILL LIKELY BRING SOME RELIEF FROM HUMIDITY...AND MINOR
TEMPERATURE RELIEF...WITH HIGHS DROPPING BACK INTO THE UPPER
80S/LOW 90S. WENT SLIGHTLY ABOVE HPC NUMBERS SOME PERIODS.

ON POPS...MAY SEE SOME THUNDERSTORMS WITH A WEAK FRONTAL SYSTEM
OVER THE WEEKEND INTO EARLY NEXT WEEK...BEFORE DRY WEATHER RETURNS
WITH SURFACE HIGH MONDAY NIGHT INTO TUESDAY. HPC NUMBERS WERE A
BIT SPORADIC AND GENERALLY WENT NEAR ENSEMBLE NUMBERS.

MAY END UP NEEDING TO EXTEND HEAT WARNING INTO SUNDAY...BUT WITH
AMPLE TIME TO MAKE THIS DECISION...WILL DEFER FOR NOW. A LOT CAN
CHANGE BETWEEN NOW AND DAY 5.

&&

.AVIATION.../FOR 202100Z TAF UPDATES/...

WILL KEEP CB GROUPS IN THROUGH 00Z AS THERE WERE A COUPLE OF
ISOLATED STORMS OUT THERE...AND TEMPERATURES WERE IN THE UPPER 90S
WHICH HAS ALLOWED THE CAP TO BREAK. IN ADDTION...WINDS HAVE TURNED
SOUTHEAST AT BMG AS AN OUTFLOW BOUNDARY HAS MOVED THROUGH THERE FROM
A BIG STORM JUST TO THE SOUTH. FINALLY...BUMPED UP WINDS BASED ON
OBSERVATIONS THROUGH 00Z. PREVIOUS DISCUSSION FOLLOWS...

SURFACE HIGH PRESSURE FROM SOUTHEAST STATES TO FORECAST AREA
THROUGH THE PERIOD. HIGH PRESSURE ALOFT REMAINING OVER AREA.

PERSISTENT SCT TO BKN CIRRUS AT 25 THOUSAND FEET. SCT-BKN TOWERING
CUMULUS WITH BASES 5 THOUSAND FEET THIS AFTERNOON.

VISIBILITIES P6SM...EXCEPT AREAS MVFR IN HAZE 09Z-13Z THURSDAY.

WINDS MAINLY SOUTHWEST LESS THAN 10 KNOTS.
