Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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 12:00Z, 8.5 hours before the alert went out and 152 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.

Area forecast discussion, May 27, 3:57 PM EDT, 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
357 PM EDT WED MAY 27 2009

.SHORT TERM.../TONIGHT THROUGH THURSDAY NIGHT/...

DEEP MOISTURE ENSCONCED IN THE CWA WITH DEWPOINTS IN THE MID TO
UPPER 60S WITH SOME STATIONS IN THE LOW 70S. SFC BOUNDARY EVIDENT
IN SFC OBS LIES BACK ACROSS ILLINOIS WITH LOW CENTERED IN THE NE
CORNER OF THE STATE AND WINDS VEERING THROUGH PIA AND STL. DRIER
AIR LIES WELL BACK ACROSS MN-WI AND NORTH OF THE WARM FRONTAL
BOUNDARY IN UPPER MICHIGAN. ALOFT...STRONG WESTERLIES STILL
LOCATED WELL NORTH OVER CANADA WHILE A MID LEVEL SHORTWAVE TROUGH
CENTERED OVER THE PLAINS IS MAKING SLOW PROGRESS EAST.

TSRA HAVE BEEN FIRING ALREADY THIS AFTERNOON WITH MOST ACTIVITY
FAVORING THE EASTERN HALF OF THE CWA WHERE RUC ANALYSIS INDICATES
DEEPEST MOISTURE LIES.  THIS SHOULD CONTINUE TO BE THE FOCUS FOR THE
MOST ORGANIZED ACTIVITY...SLIDING EASTWARD INTO OHIO AS THE
AFTERNOON PROGRESSES. STILL WITH JUICY BL MOISTURE HANGING AROUND AND
CONVECTIVE TEMPS BEING REALIZED UNDER AFTERNOON SUN AND SBCAPES
NEAR 1500 J/KG...STORMS MAY STILL POP FURTHER WEST...AND LIKELY
VS CHC POPS EAST OF I-69 WILL BE A PRESS TIME DECISION BASED ON
TRENDS.

SFC BNDRY IS VERY SLOW TO MOVE THROUGH THE CWA GIVEN LACK OF ANY FLOW
AND MID LEVEL SHORTWAVE CATCHES UP AS THE FRONT GETS TO EASTERN EDGE
OF CWA BY THURSDAY MORNING.  NAM12 HANGS THE FRONT UP IN THE LIMA
AREA AND DOESNT CLEAR THE CWA UNTIL NEAR 00Z FRI. OTHER MODEL
GUIDANCE IS VARYINGLY QUICKER...WITH THE LOCAL WRF BEING THE NEXT
SLOWEST AFTER THE NAM. HAVE WEIGHTED TOWARDS THE SLOWER SOLNS GIVEN
TOTAL LACK OF OVERALL FLOW AND KEPT CHC POPS IN THE EAST THROUGH
00Z FRI WHILE DROPPING TO SLIGHT CHC WEST...BUT NOT DROPPING
COMPLETELY WITH MID LEVEL TROF AXIS NOT YET PASSING THROUGH. DRIER
AIR ARRIVES BEHIND THE BOUNDARY ON THURSDAY DROPPING DEWPOINTS
INTO THE 50S EVERYWHERE BUT THE SE WHERE SLOGGING FRONT STILL
HANGS UP...USHERING IN A MORE COMFORTABLE NIGHT.

&&

.LONG TERM...

SHRTWV OVER SWRN CANADA TODAY EXPECTED TO PROGRESS EAST INTO BASE OF
BROAD TROF SOUTH OF STNRY UPR LOW OVER NWRN HUDSON BAY RESULTING IN
DEEPENING OF THE CANADIAN TROF INTO THE GRTLKS FRI. SFC CDFNT
ASSOCIATED WITH THE SHRTWV SHOULD MOVE SE TO NW OH-IA FRIDAY AFTN.
CONVERGENCE ALONG THIS CDFNT SHOULD BE QUITE WK IN OUR AREA AS IT
ENCOUNTERS REMNANT CYCLONIC FLOW FROM SFC LOW WHICH WILL MOVE
THROUGH OUR AREA TODAY AND STILL BE LINGERING OVER SERN ONTARIO ON
FRIDAY MORNING. HWVR...MODELS TO A VARYING DEGREE HAVE SUGGESTED
THAT A WK LOW WILL DVLP ALONG THE FRONT OVER THE NRN PLAINS AND MOVE
SE. ENHANCED MOISTURE/INSTABILITY ASSOCIATED WITH THIS WK LOW WILL
PROVIDE BETTER CHANCES OF CONVECTION TO OUR WEST FRIDAY, AND
REMNANTS OF THIS CONVECTION COULD REACH SWRN PORTION OF OUR AREA AS
SHOWERS FRIDAY NIGHT. LEANED TOWARD 00Z ECMWF AS A REASONABLE
COMPROMISE BTWN WEAKER GFS AND STRONGER NAM WRT STRENGTH OF THE SFC
LOW. BACKING FLOW AND WK WAA AHEAD OF THE CDFNT SHOULD ALLOW TEMPS
TO REBOUND FROM THURSDAYS READINGS INTO THE L-M70S OVER MOST OF THE
CWA FRI...EXCEPT STILL A LITTLE COOLER NEAR LM.

A SECOND RATHER VIGOROUS SHRTWV IS EXPECTED TO ROTATE S-SE AROUND
HUDSON BAY LOW ACROSS SE CANADA SAT/SAT NGT. ASSOCIATED SFC BOUNDARY
SHOULD MOVE ACROSS OUR CWA SAT NGT. WITH WK INSTABILITY AND LIMITED
MOISTURE/FORCING IN OUR AREA WILL LEAVE THIS FROPA DRY.

HIGH PRESSURE EXPECTED TO MOVE QUICKLY EAST ACROSS THE GRTLKS ON
SUNDAY WHILE UPSTREAM ANOTHER SHRTWV MOVES INTO THE NRN PLAINS. WARM
FRONT ASSOCIATED WITH THIS SYSTEM IS EXPECTED TO MOVE INTO THE AREA
SUNDAY AFTN. AGAIN SOME DIFFERENCES REMAIN IN STRENGTH OF
CONVERGENCE/ISENT LIFT ALONG/AHEAD OF WARM FRONT SO WHILE A FEW
SHOWERS NOT TOTALLY OUT OF THE QUESTION... STUCK WITH DRY FCST FOR
NOW. CDFNT ASSOCIATED WITH THIS SYSTEM EXPECTED TO MOVE THROUGH THE
AREA ON MONDAY WITH TSRA PSBL ALONG/AHEAD OF IT. FRONT SHOULD BECOME
E-W ORIENTED WITH PSBL WAVE MOVG ALONG IT SO LINGERING POPS INTO TUE
STILL SEEMS REASONABLE. HEAVY RAINFALL APPEARS PSBL AS THIS SLOW
MOVG FRONT MOVES THROUGH MOIST/UNSTABLE AIRMASS OVER THE AREA WITH
MID LEVEL FLOW NEARLY PARALLEL TO FRONT ORIENTATION. 00Z ECMWF
SUGGESTS SOME OVERRUNNING SHOWERS MAY PERSIST INTO WED AS ANOTHER
WAVE MOVES ALONG THE FRONT. SIDED WITH MORE OPTIMISTIC GFS
SUGGESTING HIGH PRES BUILDING INTO THE AREA WITH DRIER AIRMASS.

ONLY SGFNT CHANGE TO TEMPS WAS TO LOWER THEM ON TUE. MODELS HAVE
BEEN TRENDING FASTER WITH ARRIVAL OF CDFNT EARLY NEXT WEEK AND ARE
IN GOOD AGREEMENT THAT OUR CWA WILL BE IN THE COOLER AIR BY TUE.
THUS... NO APPEARS WARMEST DAY IN THIS PD WILL BE MONDAY AHEAD OF
THE FRONT WITH HIGHS IN THE L80S OVER MOST OF THE CWA...COOLING OFF
ABOUT 10F ON TUE WITH SLIGHTLY BLO NORMAL TEMPS CONTG INTO WED.

&&

.AVIATION.../18Z TAFS/...

VERY MOIST AIRMASS CONTINUES TO SUPPORT SCATTERED CONVECTION AHEAD
OF SLOW MOVING FRONTAL BOUNDARY STILL TO OUR WEST OVER ILLINOIS.
DAYTIME HEATING REMAINS THE PRIMARY FORCING MECHANISM AND STORMS
MAY CONTINUE TO DEVELOP THROUGH AFTERNOON AS THE FRONT INCHES ITS WAY
EAST. CURRENT ACTIVITY IS FOCUSED IN THE EASTERN HALF OF THE FA
WHERE DEEPER MOISTURE IS LOCATED...AND HAVE MERELY USED VCSH FOR
KSBN THROUGH THE NEXT COUPLE OF HOURS AS MORE LIMITED DEVELOPMENT
IN WESTERN LOCATIONS THUS FAR WILL LIKELY PRECLUDE WIDESPREAD
ACTIVITY UNTIL DEEPER INTO THE AFTERNOON. WITH MOIST AIRMASS AND
MOST AREAS NOW HAVING RECEIVED SOME PRECIP...FOG DEVELOPMENT AGAIN
EXPECTED THURSDAY MORNING AS DRIER AIR BEHIND THE BOUNDARY DOES
NOT BEGIN TO ARRIVE UNTIL AFTER SUNRISE.
