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.

What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Apr 7, 2:25 PM EDT, 3 hours 23 minutes earlier.

Area forecast discussion, Apr 7, 2:25 PM EDT, 3 hours 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
225 PM EDT WED APR 7 2010

.DISCUSSION...FORECAST ISSUE IS DEVELOPING STORMS FOR THIS EVENING.

SHORT TERM...SATELLITE AND RADAR SHOW STORMS FIRING ALONG COLD FRONT
NEAR STL IN WARMEST AND MOST UNSTABLE AIR. TORNADO WATCH TO
INCLUDE THESE STORMS. EASTERN ILLINOIS STORMS TO MOVE IN BY 3PM
WHILE LINE WEST OF I-55 DUE IN BY OR BEFORE 6PM AND THEN MOVE
ACROSS FORECAST AREA THROUGH THE EVENING.

AFTER MIDNIGHT AND FROPA SHOWERS TO TAPER OFF THOUGH SOUTHEAST
COUNTIES LIKELY TO TAP INTO CONVECTION FORECAST TO BUILD NORTHEAST
FROM CURRENT DEVELOPMENT IN WESTERN TENNESSEE.

THURSDAY...MUCH COLDER AIR AND CYCLONIC FLOW TO KEEP SKIES MOSTLY
CLOUDY AND ISOLATED SHOWERS SHOULD DEVELOP UNDER THESE CONDITIONS.

THURSDAY NIGHT SKIES WILL GRADUALLY CLEAR AND ALLOW TEMPS TO DROP
INTO MID 30S. WINDS SHOULD STAY UP ENOUGH TO LIMIT FROST BUT BEARS
WATCHING FOR LATER FORECASTS.

LONG TERM...DRY WEATHER FROM FRIDAY THROUGH REMAINDER OF PERIOD AS
TROF LIFTS OUT. FRIDAY NIGHT ALSO POTENTIAL ISSUE FOR FROST AND
BEARS WATCHING. BEYOND THAT TEMPS RETURN TO A BIT ABOVE NORMAL.

&&

.AVIATION...

&&

.AVIATION...DISCUSSION FOR THE 18Z TAFS.

MAINLY MVFR CONDITIONS ARE EXPECTED THIS TAF PERIOD.

SCATTERED RAIN SHOWERS AND ISOLATED THUNDERSTORMS OVER CENTRAL
INDIANA WERE INHIBITING HEATING AND DEEPER CONVECTION EARLY THIS
AFTERNOON. STILL AS THE DEEP TROUGH PROGRESSES EASTWARD WITH
FAVORABLE MOISTURE IN PLACE TSRA DEVELOPMENT IS STILL EXPECTED.

ONGOING TRENDS SUGGEST MVFR CEILINGS ASSOCIATED WITH SOME THE
SHOWERS AND STORMS...BUT TIMING THE DEVELOPMENT WILL PROVE TO BE
QUITE DIFFICULT. BEST WINDOWS APPEAR TO BE EARLY THIS AFTERNOON
GIVEN OUR LATEST RADAR TRENDS AND AGAIN LATE THIS AFTERNOON AND
EARLY EVENING AS STRONGER DYNAMICS BEGIN TO PUSH THROUGH. THUS HAVE
TRIED TO FOCUS VCTS AND SHRA MENTIONS AROUND THESE TIMES AND EXPECT
TO MAKE MORE ADJUSTMENT AND UPDATES AS SHOWERS AND STORMS THAT
DEVELOP PUSH TOWARD THE TAF SITES.

AFTER THE COLD FRONTAL PASSAGE TONIGHT...EXPECT GUSTY WINDS TO
CONTINUE GIVEN THE CYCLONIC FLOW. SOUNDINGS AND TIME HEIGHTS
INDICATE TRAPPED STRATO CU THUS MVFR CIGS WILL BE THE WAY TO GO TO
START THURSDAY.

UPDATE...ONLY MINOR CHANGES TO THE ONGOING FORECAST THIS MORNING.
SATELLITE IMAGES DEPICT CLOUD COVER ACROSS MUCH OF THE REGION AND
THIS MAY INHIBIT MAX HEATING THIS AFTERNOON. GIVEN H8 TEMPS NEAR 11C
AND A LACK OF WARM AIR ADVECTION HAVE TWEAKED TEMPERATURES DOWN
SLIGHTLY.

PRECIP TIMING LOOKS OK BUT GIVEN THE SLOWER PROGRESSION TO THE SE
PARTS OF THE FORECAST AREA HAVE REMOVED POPS THROUGH 18Z IN THOSE
LOCATIONS AS RAIN DOES NOT APPEAR IMMINENT IN THE NEXT FEW HOURS.

IF CLOUD COVER HOLDS THIS AFTERNOON...PRECIPITATION WILL MAINLY BE
DYNAMICALLY DRIVEN...RATHER THAN BE AIDED BY DAYTIME HEATING.
