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 12:00Z, 2.2 hours before the alert went out and 199 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.

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 Aug 5, 7:30 AM EDT, 2 hours 40 minutes earlier.

Area forecast discussion, Aug 5, 7:30 AM EDT, 2 hours 40 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
730 AM EDT TUE AUG 5 2008

.AVIATION DISCUSSION...FOR THE 12Z TAFS
MAIN CONCERN FOR THE TAFS WILL BE THUNDERSTORMS. A COLD FRONT WILL
BE MOVING THROUGH INDIANA DURING THE DAY. VERY MOIST AND UNSTABLE
AIR IS AHEAD OF IT. THIS WILL PRODUCE SCT TSTMS OVER ALL TAF
LOCATIONS. OUTSIDE OF TSTMS VFR THERE WILL BE VFR CONDITIONS. SOME
MODERATE TO STRONG TSTMS WILL BE POSSIBLE WHICH MAY PRODUCE MVFR
CONDITIONS. THE FRONT WILL BEGIN TO MOVE OUT OF TAF LOCATIONS AT
00Z. AFTER 04Z-06Z THE TSTMS WILL MOVE OUT. THE MOIST LOW LVLS FROM
RAIN WILL PRODUCE MVFR VSBYS IN FOG AFTER 09Z.

&&

.DISCUSSION...HEAT ADVISORY CONTINUES FOR THIS AFTERNOON FOR SW
PORTION OF THE CWA.

MAIN ISSUES ARE IN THE SHORT TERM WITH PRECIP AND TEMPS.  WILL USE A
NAM/GFS/SREF BLEND FOR THIS FCST.

A THUNDERSTORM COMPLEX WAS MOVING SE INTO THE NORTHERN 1/3 OF THE
CWA THIS MORNING.  AT THIS TIME THERE IS NO SEVERE ASSOCIATED WITH
THIS BUT A LOT OF RAIN IS FALLING NORTH OF LAFAYETTE INTO THE
TIPPECANOE AND WABASH RIVERS.  WILL CONTINUE WITH HIGH POPS EARLY
THIS MORNING IN AREAS WHERE TSRA WILL OCCUR AS THE COMPLEX MOVES
THROUGH.  AT 07Z A COOL FRONT WAS APPROXIMATELY FROM CHICAGO TO
KANSAS CITY.

TODAY...H85 CHART SHOWS 23C AIR MOVING INTO CENTRAL INDIANA FROM
ILLINOIS TODAY.  EVEN WITH CONVECTIVE CLOUDS DEBRIS...THAT WILL GIVE
US A HIGH IN THE LOW 90S.  HEAT INDEX VALUES WILL HOVER RIGHT AROUND
100...ESPECIALLY IN OUR SW CWA WHERE A HEAT ADVISORY IS CURRENTLY IN
EFFECT.

ASIDE FROM THE HEAT A COOL FRONT WILL MOVE THROUGH CENTRAL INDIANA
TODAY.  AHEAD OF THIS FRONT VERY UNSTABLE AIR WILL BE IN PLACE AND
IT WONT TAKE MUCH TO GET THUNDERSTORMS GOING.  THERE IS STILL SOME
UNCERTAINTY AS FAR AS HOW WIDESPREAD TSRA DEVELOPMENT WILL BE AND
ITS POSSIBLE THAT SOME AREAS STILL WILL NOT SEE ANY RAIN WITH THIS.

TONIGHT...TIMING OF THE COOL FRONTAL PASSAGE IS STILL IFFY SO
THUNDERSTORMS COULD LINGER INTO THE EVENING AND OVERNIGHT.  WILL
CONTINUE WITH CHANCE POPS AND LOWS AROUND 70.

WEDNESDAY THROUGH SATURDAY...THE NAM AND GFS DROP A SHORT WAVE INTO
THE SOUTHERN PORTION OF THE CWA ON WED/WED NIGHT AND BOTH BRING IN
SOME QPF WITH IT.  HAVE INCLUDED A LOW CHANCE POP IN THAT AREA.

THE H5 HIGH THAT BROUGHT THE HEAT WILL SLOWLY RETROGRADE AND ALLOW A
TROUGH TO DROP SOUTH ACROSS THE GREAT LAKES AND OHIO VALLEY
REGIONS.  THIS WILL BRING A WELCOME COOL DOWN TO THE STATE FROM
THURSDAY THROUGH THE WEEKEND AND WILL KEEP US DRY AS WELL.
