The radar

The Northern Indiana radar (KIWX), 94 km from the middle of the area, began a volume at 04:35 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

The nearest sounding before it

Cncnati-Daytn, OH (KILN), launched 00:00Z, 4.6 hours before the alert went out and 218 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 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 13, 8:30 PM EDT, 4 hours 4 minutes earlier.

Area forecast discussion, May 13, 8:30 PM EDT, 4 hours 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
830 PM EDT THU MAY 13 2010

.UPDATE...FRONTAL SYSTEM APPEARS TO BE ACROSS THE FAR NORTHWEST
SECTIONS OF THE FORECAST AREA. AIR MASS IS MODERATELY UNSTABLE SOUTH
OF THE FRONT WITH LIFTED INDICES DOWN TO -6. SOME CONVECTION IS
TRYING TO GET GOING ALONG THE FRONT. ADDITIONAL CONVECTION THAT
ORIGINATED IN THE SOUTHERN PLAINS EARLIER TODAY IS NOW PROGRESSING
THROUGH SOUTHERN ILLINOIS. GIVEN THE CURRENT INSTABILITY AXIS ACROSS
THE AREA...SEEMS REASONABLE TO BELIEVE THERE IS A CONTINUED THREAT
FOR CONVECTIVE DEVELOPMENT ALONG THE FRONT LATER TONIGHT. WILL
CONTINUE WITH POPS TONIGHT.

APPEARS THERMAL AND SHEAR PARAMETERS STILL FAVORABLE FOR SEVERE
STORMS AHEAD OF FRONT...SO WILL HAVE TO KEEP AN EYE ON THE
CONVECTIVE TRENDS OVER THE NEXT FEW HOURS.

&&

.SYNOPSIS...
LOW PRESSURE WAS FOUND ACROSS SE MINNESOTA EARLY THIS AFTERNOON
WITH A COLD FRONT THAT STRETCHED SOUTH ACROSS IOWA TO CENTRAL
MISSOURI AND SOUTHERN ARKANSAS. SW SURFACE FLOW WAS IN PLACE AHEAD
OF THE FRONT ACROSS CENTRAL INDIANA. SATELLITE IMAGES SHOW DEBRIS
CIRRUS CLOUDS ACROSS THE STATE ALONG WITH SOME CU TRYING TO
DEVELOP. CONVECTION WAS BUILDING ACROSS CENTRAL KENTUCKY AND SW
OHIO...WHILE SHOWERS ACROSS CENTRAL ILLINOIS NEAR THE FRONT WERE
DIMINSHING. NEWER CONVECTION WAS DEVELOPING OVER SOUTHWEST
INDIANA.

&&

.SHORT TERM /TODAY THROUGH SATURDAY/...
MAIN FORECAST CHALLENGE TODAY WILL BE THE POPS THIS AFTERNOON AND
TONIGHT.

GIVEN THE COLD FRONT TO OUR WEST AND THE VERY MOIST DEWPOINTS ACROSS
THE AREA WOULD LIKE TO INCREASE POPS THIS AFTERNOON AND EVENING.
SPC HOURLY MESOANALYSIS DEPICTS BEST INSTABILITY ACROSS SE
INDIANA...NORTHERN KENTUCKY AND SW OHIO. STILL AS WE APPROACH MAX
DAYTIME HEATING AND STILL CAPE VALUES IN EXCESS OF 2000 J/KG ACROSS
THE AREA LEAD ME TO BELIEVE DEVELOPMENT WILL STILL OCCUR. BACK EDGE
OF FAVOARBLE CAPES REMAINS ACROSS EAST CENTRAL ILLINOIS AND APPEARS
TO BE MOVING EAST. GFS FORECAST SOUNDINGS SHOW MID LEVEL INVERSION
IN PLACE AROUND H8...AND THIS MAY BE LIMITING CONVECTION. SOUNDINGS
HINT THAT THE CAP WILL BE LOST BY 00Z. TIME HEIGHT SHOW SOME LIFT
AND MOISTURE AVAILABLE...MUCH MUCH OF THE SYSTEM APPEARS TO GET
STRETCHED APART LATER THIS AFTERNOON. THUS THE BEST WINDOW FOR
CONVECTION WILL BE LATE THIS AFTERNOON AND EARLY EVENING AS THE CAP
IS LOST AND DAYTIME HEATING INSTABILITY REMAINS IN PLACE. AFTER
HEATING IS LOST...ANY STORMS SHOULD QUICKLY DIMINISH FROM WEST TO
EAST ACROSS THE FORECAST AREA. THUS WILL FOCUS POPS MAINLY DURING
THE LATE AFTERNOON AND EVENING HOURS...RAISING POPS FROM GUIDENCE
PRIOR TO 00Z BUT STICKING CLOSE TO MAVMOS AFTER 00Z. MAY WAIT FOR A
LATER ISSUANCE TODAY DUE TO INCORPORATE THE LATEST RADAR TRENDS INTO
THE FORECAST. GIVEN THE POSSIBLE RAIN BUT EXPECTED COLD AIR
ADVECTION WILL LEAN COLDER THAN MAVMOS FOR LOWS.

ON FRIDAY...HIGH PREESURE OVER THE CENTRAL PLAINS STATES WILL BE
BUILDING ACROSS INDIANA. WITH WEAK UPPER LEVEL RIDGING ALSO
BUILDING...A DRY BUT COOLER DAY IS EXPECTED. TIME HEIGHT SECTIONS
POINTING TOWARD SOME MID LEVEL MOISTURE ALONG WITH BUT WITH GOOD
SUBSIDENCE. CU RULE REMAINS SLIGHTLY NEGATIVE. THUS WITH EXPECTED
CLOUDS AND WEAK COLD AIR ADVECTION...WILL LEAN COOLER THAN MAVMOS
FOR HIGHS ON FRIDAY.

HIGH PRESSURE WILL CONTINUE TO BUILD ACROSS CENTRAL INDIANA ON
FRIDAY NIGHT AND SATURDAY BEFORE BEGINNING TO SLIDE EAST ACROSS THE
GREAT LAKES BY SATURDAY NIGHT. SURFACE FLOW WILL REMAIN
NORTHEASTERLY WHICH IS TYPICALLY UNFAVORABLE FOR CLEAR SKIES. THUS
WILL KEEP SKIES PARTLY CLOUDY BOTH FRIDAY NIGHT AND SATURDAY. BETTER
CHANCES FOR MORE SUNSHINE ON SATURDAY AS STRONGER RIDGING WILL BE
BUILDING ALOFT. CLOUDINESS WILL BE KEY IN LOW TEMPERATURES ON FRIDAY
NIGHT AND DUE TO THIS UNCERTAINLY WILL NOT TREND FAR FROM
MAVMOS...AS IT APPEARS OVERALL PRETTY REASONABLE. SINCE WE ARE
EXPECTING MORE SUNSHINE ON SATURDAY WILL KEEP A WARMING TREND FOR
HIGH TEMPERATURES ON SATURDAY...WHICH WILL BE WARMER THAN THE MAVMOS.

ON SATURDAY NIGHT CLOUDS ARE EXPECTED TO INCREASE AS THE LINGERING
FRONTAL BOUNDARDY TO SOUTH BEGINS TO PUSH BACK NORTH AGAIN AS A WARM
FRONT. GIVEN THE EXPECTED WARM AIR ADVECTION AND INCREASEING CLOUD
COVER WILL TREND AT OR ABOVE MAVMOS...PARTICULARLY ACROSS THE
SOUTHWEST WHERE CLOUDS WILL ARRIVE FIRST.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
ECMWF AND GFS BRING A WARM FRONT INTO CENTERAL INDIANA FROM THE
SOUTHWEST ON SUNDAY AFTERNOON AND MONDAY NIGHT AS AN UPPER TROUGH
APPROACHES ALOFT FROM THE WEST. GOOD FORCING AND MOISTURE SHOULD
BE IN PLACE AS THIS SHOULD BE OUR NEXT PRECIPITATION EVENT.

UPPER LOW LINGERING ACROSS NORTHERN INDIANA AND THE SOUTHERN GREAT
LAKES ON TUESDAY...BUT MOISTURE AT THE MOMENT APPEARS LIMITED. STILL
GIVEN THIS...LOW CHANCE POPS ON TUESDAY...PARTICULARLY ACROSS THE
NORTH APPEAR WARRENTED.

HIGH PRESSURE AND UPPER RIDGEING ARE EXPECETD TO BUILD ACROSS THE
AREA IN THE WAKE OF THE LOW ON WEDNESDAY AND THURSDAY. WITH SURFACE
FLOW REMAINING OUT OF THE NORTH OR NORTHEAST EXPECT COOLER AND
SLIGHTLY BELOW NORMAL TEMPERATURES.

&&

.AVIATION /DISCUSSION FOR 140000Z TAF ISSUANCE/...
CONVECTIVE COMPLEX DEVELOPING IN MO HAS SHOWN MARKED WEAKENING IN
THE LAST HOUR DESPITE MOVING ON A NE TRACK INTO A MORE UNSTABLE
ENVIRONMENT. IN ANY CASE...THIS COMPLEX APPEARS TO BE ON TRACK TO
AFFECT CENTRAL AND NORTHERN INDIANA LATER TONIGHT. HAVE TIMED
COMPLEX TO BEGIN AFFECTING THE FORECAST AREA BY 11 PM THIS
EVENING...SO HAVE INCLUDED MENTION OF -SHRA WITH CB GROUP FOR
SITES SUCH AS KLAF/KHUF AND KIND AFTER MIDNIGHT. EXPECTING
CONVECTION TO CONTINUE TO STRUGGLE TO DEVELOP...ESPECIALLY WITH
THE LOSS OF HEATING IN THE NEXT HOUR OR TWO. HAVE NOT INCLUDED
ANYTHING LOWER THAN VFR FOR THE TAF ISSUANCE...AS ANY CONVECTION
THAT DOES DEVELOP WILL BE PRETTY SPARSE AND ISOLATED IN
NATURE...AND VERY HARD TO NAIL DOWN IN THE TAFS AT THE MOMENT.

OTHERWISE...SOUTHWEST WINDS WILL WANE AFTER SUNSET.
