Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Cncnati-Daytn, OH (KILN), launched 12:00Z, 7.6 hours before the alert went out and 170 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 22, 12:15 PM EDT, 3 hours 18 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
1215 PM EDT SUN MAY 22 2011

.UPDATE...
THE NEAR TERM SECTION HAS BEEN UPDATED BELOW

&&

.SYNOPSIS...LOW PRESSURE OVER THE PLAINS STATES WILL SLOWLY PUSH
EAST OVER THE NEXT FEW DAYS...PASSING NORTH OF INDIANA THROUGH THE
GREAT LAKES BY TUESDAY. WARM AND MOIST AIR ON SOUTHERLY WINDS WILL
STREAM ACROSS INDIANA TODAY THROUGH MONDAY...BRINGING CHANCES FOR
SHOWERS AND THUNDERSTORMS EACH DAY.

THE BEST CHANCE FOR STORMS WILL BE ON MONDAY NIGHT AS THE TRAILING
COLD FRONT FROM THE PASSING LOW TO THE NORTH PUSHES ACROSS
INDIANA. THE COLD FRONTAL BOUNDARY WILL THEN LINGER NEAR CENTRAL
INDIANA THROUGH THE WORKWEEK...BRINGING SHOWERS AND STORM CHANCES
EACH DAY.

&&

.NEAR TERM /TODAY/...

HAD TO UPDATE MORNING POPS BASED ON RADAR TRENDS AS QUITE A BIT OF
ACTIVITY WENT UP ALONG AN COLD OUTFLOW BOUNDARY ACROSS EASTERN
ILLINOIS AND ARE NOW PROMPTLY MARCHING NORTHEAST ACROSS CENTRAL
INDIANA AROUND 40 MPH. THE STORMS HAVE WEAKENED SOMEWHAT FROM
EARLIER WHEN ONE SEVERE THUNDERSTORM WARNING AND A COUPLE STRONG
THUNDERSTORM ADVISORIES WERE ISSUED FOR HAIL POTENTIAL. LEFT
AFTERNOON SMALL CHANCE POPS ALONE AS IT APPEARS THERE WILL BE A LULL
IN THE ACTIVITY.

PREVIOUS NEAR TERM DISCUSSION...PROTECTIVE UPPER RIDGE HAS MOVED
EAST OF INDIANA AS WATER VAPOR IMAGERY SHOWS LOW PRESSURE SPINNING
OVER NEBRASKA AND SOUTH DAKOTA. WARM AND MOIST SOUTHERLY FLOW WAS IN
PLACE ACROSS CENTRAL INDIANA WITH DEW POINT TEMPERATURES IN THE
LOWER 60S. RADAR MOSAICS SHOW A LINE OF THUNDERSTORMS APPROACHING
WESTERN ILLINOIS.

GFS AND NAM SUGGEST BOTH SUGGEST A SHORT WAVE ASSOCIATED WITH THE
ONGOING THUNDER TO THE WEST TO PROGRESS ACROSS CENTRAL INDIANA
THIS MORNING. HOWEVER...GIVEN THIS PATTERN WITH THE LACK OF
THUNDERSTORM DEVELOPMENT YESTERDAY AS WELL THE CONTINUED
APPEARANCE OF A LACK OF STRONG VERTICAL FORCING...CONFIDENCE IS
BECOMING LOW. THUS WILL WORK ON MORE OF THE CERTAINTIES.

PREVIOUSLY MENTIONED ONGOING CONVECTION IS EXPECTED TO PUSH
TOWARD INDIANA OVERNIGHT BUT RAPID REFRESH DEPICTS THIS TO WEAKEN
AS IT PUSHES EAST. FURTHERMORE FORECAST SOUNDINGS SHOW QUITE THE
UNSTABLE AIR MASS IN PLACE ACROSS CENTRAL INDIANA THIS AFTERNOON
WITH CAPE IN EXCESS OF 1500 J/KG AND LI/S NEAR -5. THUS EXPECT
SOME SCT CONVECTION TO BREAK OUT THIS AFTERNOON DUE TO DAYTIME
HEATING. THUS WILL KEEP ONGOING LOW CHANCE POPS IN THE FORECAST
THROUGH THE DAY. GIVEN PLENTY OF SUNSHINE EXPECTED TODAY WILL
TREND HIGH TEMPERATURES CLOSE TO MAVMOS.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...

MAIN FORECAST CHALLENGE DURING THIS PERIOD WILL BE POPS. GFS AND
NAM BOTH EJECT A COUPLE OF SHORT WAVES ACROSS INDIANA TONIGHT AND
MONDAY. CONFIDENCE IS NOT HIGH IN THESE FEATURES ACTUALLY
RESULTING IN PRECIPITATION. NOCTURNAL JET DYNAMICS ONLY MUSTER
ABOUT 35 KTS AT THE LLJ. ISENTROPIC LIFT IS NO HELP TO GENERATE
LIFT. TIME HEIGHT SECTIONS INDICATE SUBSIDENCE. TONIGHT AND MONDAY
MORNING.

THE ONLY THING REALLY GOING FOR PRECIPITATION CHANCE TONIGHT AND
MONDAY WILL BE DAYTIME HEATING AS INSTABILITY WILL REMAIN EARLY
THIS EVENING FROM ANY ONGOING PRECIPITATION THAT DOES END UP
DEVELOPING. WITH A SIMILAR AIR MASS IN PLACE ACROSS CENTRAL
INDIANA AHEAD OF THE COLD FRONT...AGAIN INSTABILITY SHOWERS AND
STORMS SEEM QUITE REASONABLE AS FORECAST SOUNDINGS INDICATE CAPE
IN EXCESS OF 2500 J/KG AND LIFT INDICES LESS THAN -6. STEEP LAPSE
RATE ARE IN PLACE WITH A MINIMAL CAP. GIVEN ALL OF THIS WILL FOCUS
POPS DURING THE EVENING HOURS TONIGHT AS DAYTIME HEATING
CONVECTION WANES AND RESET CONDITIONS FOR MONDAY...WITH BEST
CHANCES DURING THE AFTERNOON AS HEATING RESUMES.

AS FOR TEMPS WILL STICK CLOSE TO PERSISTENCE FOR LOWS TONIGHT AS
LITTLE CHANGE IN AIR MASS IS EXPECTED. GIVEN OUT 850MB
TEMPERATURES THE WARMER 850MB TEMPERATURES LOOK BETTER THAN THE
COLD METMOS. WILL TREND AT OR SLIGHTLY BELOW MAVMOS FOR HIGHS.

MONDAY NIGHT THE TRAILING COLD FRONT WILL PUSH TOWARD INDIANA AND
WITH A WARM UNSTABLE AIR MASS IN PLACE MORE UPPER SUPPORT WILL NOW
BE AVAILABLE TO ACT AS A TRIGGER. FORECAST SOUNDINGS SHOW THE
COLUMN BECOMING SATURATED ON MONDAY NIGHT THROUGH TUESDAY MORNING.
FURTHERMORE LOWER LEVEL Q VECTORS SHOW GOOD CONVERGENCE ACROSS THE
AREA. THUS WILL RAISE THE POPS ON MONDAY NIGHT AND TREND LOW
TEMPERATURES TOWARD THE WETBULBS...WARMER THAN MAVMOS GIVEN THE
EXPECTED RAIN.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...

THE BIG CHALLENGE IN THE EXTENDED WILL BE MAINLY TEMPERATURES AND
POPS AS MODELS DIFFER ON HOW FAR SOUTH A COLD FRONT WILL GET AS IT
DROPS SOUTHEAST ACROSS CENTRAL INDIANA MIDWEEK. THE ECMWF IS THE
FURTHEST NORTH OF THE BUNCH WITH THE FRONT SLIDING TO NEAR IND BY
00Z WEDNESDAY BUT THEN STALLING THROUGH 12Z FRIDAY BEFORE A FINALLY
WAVE LIFTS NORTHEAST ALONG THE FRONT WITH A TRAILING COLD FRONT
MOVING THROUGH FRIDAY NIGHT. MEANWHILE...THE 12Z OPERATIONAL GFS AND
ESPECIALLY THE 12Z CANADIAN AND 00Z GEF MEAN WERE MUCH FURTHER SOUTH
DROPPING THE FRONT TO NEAR THE KENTUCKY BORDER BY 12Z THURSDAY. THE
12Z OPERATIONAL GFS DOES...HOWEVER COME MORE INTO THE LINE WITH THE
ECMWF BY FRIDAY NIGHT LIFTING THE AFOREMENTIONED WAVE NORTHEAST
ACROSS INDIANA AND PUSHING A COLD FRONT THROUGH FRIDAY NIGHT INTO
SATURDAY. WILL...GO AHEAD AND LEAN TOWARD THE MIDDLE OF THE ROAD GFS
WHICH MATCHES UP WELL WITH HPC. WITH THAT IN MIND...PREFER THE 12Z
GFS WITH COOLER AND SLIGHTLY BELOW NORMAL HPC TEMPERATURES LATE WEEK
AND CONTINUED THUNDERSTORM CHANCES THROUGH SATURDAY.

&&

.AVIATION.../DISCUSSION FOR 221800Z TAFS/...

EXPECT VFR CONDITIONS THROUGH THE PERIOD AWAY FROM THUNDERSTORMS AS
INCREASING WINDS WILL PREVENT FOG TONIGHT. MODELS SUGGESTING
SCATTERED TO BROKEN VFR DIURNALLY DRIVEN CUMULUS DEVELOPMENT THROUGH
SUNSET. MAIN CHALLENGE IS TIMING AND COVERAGE OF CONVECTIVE
ACTIVITY...BUT MAIN EXPECTATION IS FOR CONTINUED SCATTERED AFTERNOON
ACTIVITY FOLLOWED POTENTIALLY BY AN EVENING STRONG TO SEVERE SQUALL
LINE. WITH TIMING AND COVERAGE IN QUESTION...WILL JUST THROW IN CB'S
FOR NOW THIS AFTERNOON UNLESS IT CAN BE BETTER PINNED DOWN JUST
BEFORE ISSUANCE TIME. OTHERWISE...WILL LIKEWISE KEEP CB'S IN TONIGHT
AND TOMORROW AS INSTABILITY REMAINS ABOVE 500 J/KG THROUGH THE NIGHT
AND CONFIDENCE NOT HIGH ON TIMING WITH SO MANY IMPULSES MOVING
THROUGH THE FAST SOUTHWEST FLOW ALOFT.

BUFKIT SUGGESTS WIND GUSTS 25 KNOTS OR MORE ARE POSSIBLE THIS
AFTERNOON AND MONDAY AFTERNOON. A COLD FRONT SHOULD BE KNOCKING ON
THE DOOR OF IND BY 00Z TUESDAY BUT WILL KEEP IT JUST TO THE
NORTHWEST AND NOT MENTION A WIND SHIFT AND ADJUST IN LATER TAFS IF
NEED BE.
