What was reported inside it

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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.

NWS Indianapolis, IN wrote its last area forecast discussion before this severe thunderstorm warning went out at May 10, 2:54 PM EDT, 11 minutes earlier.

Area forecast discussion, May 10, 2:54 PM EDT, 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
254 PM EDT TUE MAY 10 2011

.UPDATE...
THE SYNOPSIS...NEAR TERM...SHORT TERM AND LONG TERM SECTIONS HAVE
BEEN UPDATED BELOW.

&&

.SYNOPSIS...
A WARM FRONT WILL LIFT NORTHEAST ACROSS THE AREA EARLY THIS
EVENING AND THEN STALL OUT. MEANWHILE AN UPPER RIDGE WILL BUILD
INTO THE AREA FOR MID WEEK...BEFORE AN UPPER LOW MOVES INTO THE
AREA FOR THE WEEKEND. THE UPPER RIDGE WILL BRING WARM AIR AND
LOWER CHANCES FOR RAIN...BUT COOLER CONDITIONS AND HIGHER CHANCES
FOR RAIN WILL RETURN WITH THE UPPER LOW THIS WEEKEND.

&&

.NEAR TERM /REST OF THIS AFTERNOON AND TONIGHT/...
ANALYSIS AS OF 230 PM THIS AFTERNOON DEPICTS A WARM FROM ORIENTED
FROM NW TO SE ACROSS CENTRAL INDIANA. THIS FRONT WILL CONTINUE TO
SLOWLY PUSH NORTHWARD THROUGH EARLY THIS EVENING BEFORE EVENTUALLY
STALLING ACROSS NORTHERN INDIANA.

INSTABILITY IN THE WARM SECTOR QUITE IMPRESSIVE AT THIS HOUR WITH
A LARGE AREA OF MLCAPE IN EXCESSIVE OF 3K J/KG...VERY NICE VEERING
SHEAR PROFILES...40-50KT BRN SHEAR. GIVEN THIS ENVIRONMENT SUPERCELLS
ARE A GOOD POSSIBILITY...WITH LARGE HAIL (WHICH HAS ALREADY BEEN
REPORTED) DAMAGING WINDS...AND EVEN A FEW ISOLATED TORNADOES BEING
THE MAIN THREATS. SPC HAS PLACED MOST OF THE FA IN A SLIGHT RISK
FOR SEVERE...AND ISSUED SVR TSTM WATCH 268 EARLIER THIS AFTERNOON
FOR MANY COUNTIES IN THE AREA.

THE UPSHOT IS THAT THE SVR THREAT WILL WANE WITH SUNSET...AND ONLY
LOW CHANCES OF TSTMS WILL LINGER OVERNIGHT ACROSS THE NRN COUNTIES
CLOSEST TO THE BOUNDARY. LOWS TONIGHT MID TO UPPER 60S.

&&

.SHORT TERM /WEDNESDAY THROUGH SATURDAY/...
THE UPPER RIDGE BEGINS TO MOVE OFF TO THE EAST WEDNESDAY AFTERNOON
AND LOSE ITS INFLUENCE. WITH THE EXPECTED INSTABILITY FEEL THAT
LOW POPS ARE WARRANTED ALL AREAS WEDNESDAY AFTERNOON. WITH A
RELATIVELY WARM START AND SUNSHINE...HIGHS IN THE MID 80S LOOK
GOOD...WHICH IS A BLEND OF MOS.

THE UPPER RIDGE WILL CONTINUE TO MOVE EAST INTO FRIDAY AS THE UPPER
LOW BEGINS ITS APPROACH. INSTABILITY WILL STILL BE AROUND. GIVEN
THESE CONVECTION WILL HAVE A CHANCE TO DEVELOP DURING THE PERIOD...SO
WENT LOW POPS INTO THURSDAY NIGHT. WENT A LITTLE HIGHER...BUT
STILL CHANCE CATEGORY...ON FRIDAY WITH THE UPPER LOW GETTING
CLOSER ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS LOOKS LIKELY.

&&

.LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/...
PERIOD LOOKS TO BE COOL... CLOUDY... WITH WIDESPREAD DECENT CHANCES
FOR SHOWERS AND THUNDERSTORMS THROUGHOUT THE WEEKEND. UPPER LEVEL
CUTOFF LOW PRESSURE SYSTEM LOOKS TO TRACK SOUTHEASTWARD FROM THE
WEST OF THE OHIO VALLEY DURING THE WEEKEND AND INTO EARLY NEXT WEEK.
THIS IS SUPPORTED BY BOTH ECMWF AND GFS... BUT THERE ARE SOME
DIFFERENCES IN THE INTENSITY AND TRACK DURING THIS PERIOD. BY MONDAY
NIGHT... THE GFS HAS THE SYSTEM STRONGER AND CENTERED OVER
TENNESSEE... WHEREAS THE ECMWF HAS THE SYSTEM FURTHER SOUTH NEAR THE
GULF COAST.

AFTER COLLABORATING WITH OTHER OFFICES ON UNCERTAINTY WITH THE
GUIDANCE... DECIDED TO USE A BLEND OF HPC AND ECMWF.  LOOKS LIKE
BEST CHANCE FOR THUNDERSTORMS WOULD BE SATURDAY INTO SUNDAY AS SFC
LOW TRACKS SOUTHEASTWARD ALMOST DIRECTLY OVER THE AREA. TAPERED OFF
PRECIP AMOUNTS AND DECREASED POPS AS THE SYSTEM DEPARTS AND HIGH
PRESSURE BUILDS IN EARLY NEXT WEEK. TEMPS LOOK TO CONTINUE TRENDING
DECENTLY BELOW NORMAL WITH LOWS IN THE UPPER 40S TO LOW 50S MONDAY
AND TUESDAY MORNING. STUCK CLOSE TO HPC FOR WINDS.

&&

.AVIATION /DISCUSSION FOR THE 10/18Z TAFS/...
THE MAIN CONCERN FOR THE TAF PACKAGE IS AFTERNOON CONVECTION. IT
APPEARS THAT THE AFTERNOON HEATING AND INSTABILITY WILL BE ENOUGH
TO TRIGGER PULSE STORMS THROUGH THE DAY. KLAF AND KHUF ALREADY
HAVE THUNDERSTORMS IN THE VICINITY. THIS ACTIVITY SHOULD TAPER OFF
AFTER SUNSET WHEN THEY LOSE AFTERNOON HEATING. OTHERWISE...VFR
CONDITIONS WILL PREVAIL FOR ENTIRE TAF PERIOD EXCEPT FOR POSSIBLE
DROPS TO MVFR CATEGORY WITH ANY STORMS.

OTHERWISE...JUST SOME MID AND HIGH LEVEL CLOUDS FOR THE REMAINDER
OF TAF PERIOD AS RIDGE BUILDS INTO THE FORECAST AREA. WINDS WILL BE
SOUTH/SOUTHWESTERLY AT 5 TO 10 MPH EXCEPT FOR ANY STRONG GUSTS
WITH ANY STORMS THIS AFTERNOON.

&&

.IND WATCHES/WARNINGS/ADVISORIES...
NONE.
