Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

What forecasters said that day

The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Indianapolis, IN wrote its last area forecast discussion before this tornado warning went out at May 21, 2:10 PM EDT, 2 hours 16 minutes earlier.

Area forecast discussion, May 21, 2:10 PM EDT, 2 hours 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
210 PM EDT FRI MAY 21 2010

.UPDATE...
UPDATED SYNOPSIS...NEAR/SHORT/LONG TERMS & HYDROLOGY.

&&

.SYNOPSIS...
A LOW PRESSURE SYSTEM WILL PUSH EASTWARD ACROSS ILLINOIS...INDIANA...AND
OHIO THIS AFTERNOON AND EVENING...DRAGGING A COLD FRONT THROUGH
THE AREA. THIS SYSTEM WILL MOVE EAST OF THE REGION AFTER MIDNIGHT.
HIGH PRESSURE WILL BUILD BACK OVER THE REGION FOR THIS
WEEKEND...BRINGING MUCH DRIER AND WARMER WEATHER.

&&

.NEAR TERM /TONIGHT/...
ANALYSIS AS OF 2 PM THIS AFTERNOON DEPICTS A WELL DEFINED UPPER LOW
SITUATED ACROSS CENTRAL ILLINOIS AND INDIANA. THIS SLOW WILL SLOWLY
CONTINUE TO SHIFT EASTWARD THROUGH THIS EVENING. ALSO...A WEAK
SURFACE LOW IS LOCATED OVER CENTRAL ILLINOIS WITH AN ASSOCIATED COLD
FRONT TRAILING TO THE SOUTH. FORECAST FOCUS FOR THE NEAR TERM IS
PRECIP AND CONVECTIVE CHANCES.

LATEST VISIBLE SATELLITE IMAGERY SHOWS CLOUDS BECOMING MORE
SCATTERED ALONG MUCH OF CENTRAL ILLINOIS. AS THIS SYSTEM SHIFTS
EASTWARD, EXPECT CLOUDS OVER CENTRAL INDIANA TO BEGIN SCATTERING OUT
(SOMEWHAT) AS WELL...POSSIBLY ALLOWING UP A FEW MORE PEAKS OF
SUNSHINE, WHICH WILL AID INSTABILITY. THUS FAR THE CURRENT DENSE
CLOUD COVER HAS INHIBITED CONVECTION...KEEPING THOSE STORMS THAT
HAVE POPPED UP VERY SHALLOW. THIS SHOULD QUICKLY CHANGE AS THE SYSTEM
PUSHES EASTWARD ACROSS THE STATE AND CLOUDS BEGIN TO SCATTERED OUT.

IF WE DO GET SOME CLEARING...STRONGER TO SEVERE THUNDERSTORMS ARE
POSSIBLE, AND WE ARE CURRENTLY STILL IN A SLIGHT RISK FOR
SEVERE...IN ADDITION TO THUNDERSTORM WATCH #199 WHICH IS IN EFFECT
FOR MUCH OF CENTRAL INDIAN UNTIL 9 PM THIS EVENING. AT THIS POINT
MAIN THREATS WILL BE HAIL...WITH A FAIRLY LOW FREEZING LEVEL OF
AROUND 11KT FT, GETTING TOPS TO NEAR 30KT FT MAY NOT BE THAT
DIFFICULT. A SECONDARY THREAT IS BRIEF VERY HEAVY RAINFALL. WITH
PRECIPITABLE WATERS RUNNING NEAR 1.5" ANY STORM THAT DOES FORM COULD
HAVE THE POTENTIAL TO DUMP A LARGE AMOUNT OF RAIN OVER ANY GIVEN AREA.
FLASH FLOODING IS A POSSIBLE. A THIRD CONCERN IS GUSTY WINDS.
SOUNDINGS ARE NOT PARTICULARLY IMPRESSIVE WITH REGARD TO
SHEAR...SO THIS IS NOT AT THE TOP OF THE LIST IN TERMS OF THREATS.
MARGINALLY SEVERE HAIL AND HEAVY RAINFALL ARE OF PRIMARY CONCERN.

FRONT SHOULD BEGIN TO EXIT EAST INTO OHIO BEFORE MIDNIGHT AND SHOWER
ACTIVITY WILL BEGIN TO WANE AND ALSO EXIT. LOW TONIGHT MID-UPPER
50S.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
THIS WEEKEND IS SHAPING UP TO BE VERY PLEASANT...ESPECIALLY WHEN
COMPARED TO THE LAST 2 DAYS. SATURDAY WILL HAVE DECREASING CLOUDS
AS UPPER RIDGE BUILDS EAST INTO OUR REGION AND SURFACE LOW
CONTINUES EAST ACROSS NORTHERN OHIO.

BOTH NAM/GFS HAVE TRENDED A LITTLE QUICKER IN ENDING PRECIPITATION
BY SATURDAY AND WILL ONLY MENTION LOW CHANCES OF SHOWERS MAINLY
RANDOLPH COUNTY FOR SATURDAY MORNING.  AS FAR AS TEMPERATURES ARE
CONCERNED WILL MAV/MET NUMBERS ARE CLOSE AND SEEM REASONABLE.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
ECMWF/GEM/GFS CONTINUE TO BE IN GOOD AGREEMENT FOR NEXT WEEK AS A
STRONG RIDGE OF HIGH PRESSURE SITUATES ITSELF OVER THE GREAT LAKES
REGION.  A FEW AFTERNOON SHOWERS CANNOT BE RULED OUT WITH DAYTIME
HEATING.  HOWEVER...NOT ENOUGH CERTAINTY TO INCREASE POPS AT THIS
TIME DUE TO DRY FORECAST SOUNDINGS AND NO LIFTING MECHANISMS.  THE
BEST CHANCE FOR ANY PRECIPITATION WILL BE LATE IN THE WEEK AS A LOW
PRESSURE SYSTEM MOVES ACROSS CANADA.  AT THIS TIME...IT LOOKS LIKE
IT WILL REMAIN TOO FAR NORTH TO HAVE MUCH OF AN IMPACT.

AS FAR AS TEMPS...WENT WITH A BLEND OF MODELS...WHICH ALL SEEM TO
HAVE A GOOD HANDLE ON THE WARMER TEMPS.  HIGHS WILL GENERALLY TOP
OFF IN THE MID TO UPPER 80S WITH AMPLE SUNSHINE...AND LOWS WILL
BOTTOM OUT IN THE LOW TO MID 60S.

&&

.AVIATION /DISCUSSION FOR 211800Z TAF ISSUANCE/...
LATEST RADAR SHOWS A BAND OF SHOWERS AND THUNDERSTORMS JUST SOUTH
OF KLAF AND BETWEEN KHUF/KIND WITH TOPS OF 35-40 FEET. THE
ACTIVITY IS MOVING NE AT 25MPH WITH MORE SCATTERED ACTIVITY OVER
IN ERN IL. THE ACTIVITY IS OCCURRING AHEAD OF AN UPPER LEVEL LOW
NEAR ST. LOUIS..SO IT LOOKS LIKE SCATTERED THUNDERSTORMS WILL BE
THE RULE FOR OCCASIONAL MVFR IN THE VICINITY OF THE THUNDERSTORMS.
THERE IS A COLD FRONT ASSOCIATED WITH THIS SYSTEM THAT WILL ROTATE
SW TO NE ACROSS CENTRAL INDIANA LATE TONIGHT AND EARLY SATURDAY
MORNING. AS THE UPPER TROUGH MOVES ACROSS THE AREA AFTER
23/0600Z...MUCH OF THE PRECIPITATION WILL MOVE OUT OF THE
AREA...BUT WITH THE COOLER TEMPERATURES AND WET GROUND...LOW
CLOUDS/FOG WILL LIMIT VISIBILITIES TOWARDS MORNING WITH THE
POSSIBILITY OF SOME IFR CONDITIONS.

SKIES ARE EXPECTED TO IMPROVE LATE SATURDAY MORNING GIVING A RETURN
TO VFR FLYING CONDITIONS.

&&

.HYDROLOGY...
SHOWER AND THUNDERSTORM ACTIVITY THIS AFTERNOON IS EXPECTED TO
CREATE LOWLAND FLOODING ALONG PORTIONS OF THE WABASH AND WHITE
RIVERS. MUCH OF CENTRAL AND WESTERN INDIANA RECEIVED BETWEEN ONE
HALF AND NEARLY 1 1/2 INCHES OF RAIN THURSDAY NIGHT. MOST
PRECIPITATION IS EXPECTED TO FALL BY 8 PM THIS EVENING OVER THE
AREA OF CONCERN WITH ESTIMATED RAINFALL ON THE ORDER OF ONE
QUARTER TO 3 TENTHS OF AN INCH. ONLY A FEW HUNDREDTHS OF AN INCH
AT MOST ARE EXPECTED BEYOND THIS BUT GIVEN THE CONVECTIVE NATURE
AMOUNTS OF COURSE COULD VARY. WARMING TEMPERATURES AND DRY WEATHER
WILL MOVE IN STARTING TOMORROW AND CONTINUE THROUGH EARLY JUNE.
THIS WILL ALLOW SOILS TO DRY AND VEGETATION TO GROW RAPIDLY. AS A
RESULT...RIVERS IN WESTERN AND SOUTHERN INDIANA WILL RETURN TO
NORMAL LEVELS BY MAY 28.
