The Indianapolis radar (KIND), 109 km from the middle of the area, began a volume at 00:18 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 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

Lincoln, IL (KILX), launched 00:00Z, 0.2 hours before the alert went out and 117 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
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
651 PM EDT SUN MAY 30 2010

.UPDATE...
THE AVIATION SECTION HAS BEEN UPDATED BELOW

&&

.SYNOPSIS...

A COLD FRONT WILL MOVE INTO THE AREA ON MONDAY AS THE REMNANTS OF
AN UPPER LOW EJECT THROUGH THE LOWER OHIO VALLEY. THE AREA WILL
THEN BE IN ZONAL FLOW ALOFT WHICH WILL ALLOW FRONTS TO IMPACT THE
AREA INTO NEXT WEEKEND.

&&

.NEAR TERM /TONIGHT/...

MODELS ARE IN DECENT AGREEMENT SO WILL USE A BLEND. FOCUS IS ON
CHANCES FOR RAIN.

FORCING REMAINS WEAK TONIGHT WITH THE COLD FRONT WELL TO THE WEST
AND THE OLD UPPER LOW TO THE SOUTH. EXPECT ONGOING SCATTERED
CONVECTION TO LINGER INTO THE EVENING HOURS. MODELS HINT AT SOME
WEAK FRONTOGENETICAL FORCING IN THE LOWER LEVELS MOVING ACROSS THE
AREA TONIGHT...AND THIS COULD BE JUST ENOUGH FOR ISOLATED STORMS
TO CONTINUE OVERNIGHT. SINCE STORMS ARE ALREADY IN THE
FORECAST...DECIDED TO LEAVE ISOLATED MENTION OVERNIGHT.

MAV/MET TEMPERATURES ARE SIMILAR AND LOOK OK TONIGHT GIVEN
HUMID AIR OVERNIGHT.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY/...

FOCUS IS AGAIN ON CHANCES FOR RAIN. MODELS ARE IN DECENT AGREEMENT
IN THIS PERIOD AS WELL...AND WILL USE A BLEND FOR THE MOST PART.

THE COLD FRONT WILL MOVE INTO THE AREA ON MONDAY. AS MENTIONED
ABOVE...THE REMNANTS OF THE OLD UPPER LOW ACROSS THE SOUTHERN
STATES WILL MOVE ACROSS THE LOWER OHIO VALLEY. MEANWHILE...THERE
WILL BE PLENTY OF MOISTURE AND INSTABILITY FOR THEM TO INTERACT
WITH...SO WILL CONTINUE WITH CATEGORICAL POPS.

MAV TEMPS LOOK A BIT WARM MONDAY GIVEN EXPECTED RAINFALL...SO
WILL TRIM SOME.

THE FRONT WILL BEGIN TO EXIT THE AREA MONDAY NIGHT...FINALLY
LOSING ITS INFLUENCE TUESDAY MORNING. WILL GRADUALLY END POPS
THROUGH TUESDAY MORNING. A BRIEF RESPITE CAN THEN BE EXPECTED ON
TUESDAY AFTERNOON AND TUESDAY NIGHT.

MODELS HAVE BEEN HINTING FOR A FEW RUNS NOW THAT ONE OR MORE
CONVECTIVE COMPLEXES MAY IMPACT THE AREA ON WEDNESDAY. THE AREA
WILL BE IN ZONAL FLOW ALOFT AND ATMOSPHERE WILL BE UNSTABLE...SO
AN IMPULSE COULD GENERATE A FEW STORMS. SINCE THE MODELS HAVE BEEN
PERSISTENT...HAVE ADDED LOW POPS TO WEDNESDAY.

MAV/MET TEMPERATURES ARE SIMILAR AND LOOK REASONABLE DURING THE
REMAINDER OF THE SHORT TERM GIVEN EXPECTED CONDITIONS.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...

FOCUS IN THE LONG TERM WILL BE ON CHANCES FOR RAIN WITH A COUPLE
OF FRONTS THAT MOVE THROUGH THE AREA. GFS/ECMWF ARE GETTING CLOSER
IN THEIR SOLUTIONS...SO USED A BLEND.

A COLD FRONT WILL MOVE THROUGH ON THURSDAY AND WILL BRING ANOTHER
POTENTIAL ROUND OF THUNDERSTORMS. ATMOSPHERE AHEAD OF THE FRONT
WILL BE MOIST AND UNSTABLE...SO CONTINUED WITH HIGH CHANCE POPS.

FRIDAY WILL THEN BE DRY IN BETWEEN FRONTS...THEN ANOTHER FRONT ON
SATURDAY WILL BRING ANOTHER CHANCE OF RAIN. AT THE MOMENT...IT
LOOKS LIKE THE FRONT WILL BE OUT OF THE AREA FOR SUNDAY...ALLOWING
A DRY DAY THEN.

&&

.AVIATION.../FOR 310000Z TAFS/...

HIGH PRESSURE REMAINING OVER SOUTHEAST COAST THROUGH THE PERIOD.
SLOW MOVING COLD FRONT WILL CROSS INDIANA FROM NORTHWEST FROM
MONDAY INTO TUESDAY NIGHT.

ISOLATED EVENING CONVECTION SHOULD DIE BY 02Z AT THE LATEST.
WIDESPREAD TSRA DEVELOPING AFTER ABOUT 15Z MONDAY AS FRONT
APPROACHES. EXCEPT IN TSRA...CEILINGS BKN250 EARLY TONIGHT
LOWERING TO MAINLY 4500 FEET MONDAY. VISIBILITIES OUTSIDE TSRA
REMAINING P6SM SINCE CLOUDS TONIGHT WILL PREVENT FOG.

&&

.IND WATCHES/WARNINGS/ADVISORIES...
NONE.
