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 10, 2:30 AM EST, 9 hours 28 minutes earlier.

Area forecast discussion, Aug 10, 2:30 AM EST, 9 hours 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
230 AM EST WED AUG 10 2005

.DISCUSSION...FORECAST FOCUS CENTERS ON CHANCES OF TSRA OVER THE
NEXT 48 HOURS.

WEAK FRONTAL BOUNDARY APPROACHES FROM THE NORTHWEST.  NAM IS LOOKING
MORE LIKE THE GFS TODAY SO WILL USE A BLEND OF THE TWO.  FRONT
STALLS SOMEWHERE OVER THE CWA LATER TODAY.  NAM HAS IT STALLED NEAR
THE NORTHERN PORTION OF THE CWA AND THE GFS FARTHER NORTH IN
NORTHERN INDIANA.  KLOT RADAR SHOWING AN AREA OF PRECIP OUT AHEAD OF
THE FRONT THAT AS OF 07Z IS MOVING EAST.  THE FRONT CAN ALSO BE SEEN
ON KLOTS RADAR.

IN THE NEXT 24 HOURS EXPECT CLOUDS TO INCREASE AHEAD OF THE FRONT
AND SCT TSRA AS EARLY AS THIS MORNING IN THE LAFAYETTE AREA AND INTO
LATE MORNING/EARLY AFTERNOON CENTRAL INDIANA.  CONCERN WITH TEMPS
WILL BE HOW MUCH OF AN EFFECT WITH THE CLOUDS HAVE ON HIGHS TODAY.
WARMEST TEMPS ARE IN WESTERN INDIANA AS THE NOSE OF THE H85 THERMAL
RIDGE POKES INTO THAT AREA.  19-20C AT H85 IS STILL FORECAST WHICH
WOULD GIVE LOW 90S.  WITH CLOUDS THOUGH TEMPS MAY ONLY PEAK AT
89-90.

NEXT CONCERN IS THURSDAY NIGHT.  AS STALLED FRONT REMAINS IN THE
VICINITY A CHANCE OF TSRA WILL REMAIN.  THURS NITE INTO FRIDAY
MORNING CONCERNS ME AS THE FRONT WILL BE PARALLEL TO THE UPPER
FLOW...PWATS ARE AROUND 2.0...KINDEX OF 35-40...HIGH (14C) H85
DEWPOINTS...HIGH THETA E VALUES...ISENTROPIC LIFT AND GOOD UVVS ARE
ALL PRESENT WHICH INCREASES THE POSSIBILITY OF HEAVY
RAINFALL/TRAINING THUNDERSTORMS.  THESE PARAMETERS COME TOGETHER
LATE THURSDAY NIGHT AND SHIFT NORTH ON FRIDAY MORNING.  SINCE THIS
SCENARIO IS SOMEWHAT DEPENDENT ON FRONTAL POSITION, WILL RAISE POPS
TO CHANCE AND SEE IF SUBSEQUENT RUNS HAVE A BETTER HANDLE ON
POSITION.  WILL MENTION THE POSSIBILITY IN THE HWO.
