The radar

The Indianapolis radar (KIND), 103 km from the middle of the area, began a volume at 20:45 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 12:00Z, 8.7 hours before the alert went out and 188 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 flash flood 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 flash flood warning went out at May 31, 2:21 PM EDT, 2 hours 20 minutes earlier.

Area forecast discussion, May 31, 2:21 PM EDT, 2 hours 20 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
221 PM EDT MON MAY 31 2010

.UPDATE...
THE SYNOPSIS...NEAR TERM...SHORT TERM AND LONG TERM SECTIONS HAVE
BEEN UPDATED BELOW.

&&

.SYNOPSIS...

A SERIES OF COLD FRONTS WILL MOVE ACROSS THE AREA
TONIGHT...THURSDAY...AND SATURDAY AS FLOW ALOFT BECOMES ZONAL.
THIS WILL KEEP CHANCES FOR STORMS AROUND THROUGH THE WEEK.

&&

.NEAR TERM /TONIGHT/...

FORECAST FOCUS IS ON CHANCES FOR RAIN TONIGHT. MODELS ARE IN
DECENT AGREEMENT AND WILL GENERALLY USE A BLEND...ALTHOUGH LOOKS
LIKE MAVMOS MAY BE TOO FAST TO CLEAR OUT RAINFALL TONIGHT.

THUNDERSTORMS WILL MOVE ACROSS THE AREA THIS AFTERNOON AHEAD OF A
COLD FRONT. THE QUESTION BECOMES WHERE WILL THE STORMS BE AT 00Z.
AS NOTED ABOVE...MAVMOS GIVES RELATIVELY LOW POPS TONIGHT
CONSIDERING THAT THE ACTUAL FRONT DOES NOT MOVE THROUGH UNTIL LATE
TONIGHT...AND THE FACT THE RECENT RADAR TRENDS OF STORMS
DEVELOPING BACK IN MISSOURI WOULD TEND TO INDICATE A LATER EXIT OF STORMS.

THUS FEEL THAT MAV POPS LOOK TOO LOW AT MANY LOCATIONS. WILL TREND
TOWARD HIGHER MET NUMBERS...WHICH MEANS LIKELY POPS ACROSS THE
EASTERN THIRD AND CHANCE POPS ELSEWHERE. WILL LOWER POPS AFTER 06Z
DUE TO LOSS OF INSTABILITY.

WENT CLOSER TO THE WARMER OF THE MOS NUMBERS FOR LOWS TONIGHT
DUE TO THE SLOW MOVEMENT OF THE FRONT AND THE FACT THAT DRIER AIR
LAGS FRONT A BIT.

&&

.SHORT TERM /TUESDAY THROUGH THURSDAY/...

FOCUS CONTINUES TO BE ON THUNDERSTORM THREAT THROUGH THE PERIOD.
NAM LOOKS TO GO OVERBOARD WITH DEVELOPMENT OF AN AREA OF LOW
PRESSURE ON THURSDAY AND COULD HAVE BEEN INFLUENCED BY CONVECTIVE
FEEDBACK. MEANWHILE GFS IS FASTER THAN OTHER MODELS IN BRINGING
ITS FRONT THROUGH ON WED NIGHT/THURSDAY...AS IT TOO SUFFERS FROM
FEEDBACK ISSUES. WENT CLOSER TO ECMWF.

FRONT AND RAIN SHOULD BE JUST EAST OF THE AREA ON TUESDAY. DRIER
AIR WILL THEN BUILD IN AS HIGH PRESSURE MOVES INTO THE AREA.
DRY CONDITIONS SHOULD CONTINUE TUESDAY NIGHT. SOME CONCERN ABOUT
POSSIBLE MCS DEVELOPMENT AND MOVEMENT INTO THE NORTHWEST AREA BY
LATE TUESDAY NIGHT...BUT AM NOT CONFIDENT ENOUGH TO PUT POPS IN
TUE NIGHT YET.

MAV/MET TEMPERATURES ARE SIMILAR FOR TUE AND TUE NIGHT...AND THEY
LOOK REASONABLE GIVEN SUNSHINE TUESDAY AND INCREASING CLOUDS
TUESDAY NIGHT.

TOUGH CALL FOR FORECAST ON WEDNESDAY. IF MCS DEVELOPS AND MOVES
INTO THE AREA WED MORNING...TEMPERATURES WILL BE COOL. IF HOWEVER
MCS DOES NOT DEVELOP...THEN ATMOSPHERE WILL BECOME QUITE UNSTABLE
WITH SREF SHOWING A GOOD POSSIBILITY OF CAPES OVER 3000 J/KG. THIS
WILL ALLOW TSRA TO DEVELOP IN THE AFTERNOON. WITH THE UNCERTAINTY
DECIDED TO SPLIT THE DIFFERENCE AND GO CHANCE POPS WITH HIGHS IN
BETWEEN THE WARMER MAV AND COOLER MET.

A COLD FRONT WILL THEN MOVE IN FOR WEDNESDAY NIGHT AND THURSDAY
AND KEEP CHANCES FOR STORMS AROUND.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...

FOCUS CONTINUES TO BE ON CHANCES FOR RAIN. HAVE DECIDED TO GO
CLOSER TO ECMWF SINCE IT HAS HAD BETTER CONTINUITY LATELY.

FRONT SHOULD BE FAR ENOUGH SOUTH ON FRIDAY FOR DRY
CONDITIONS...BUT ANOTHER FRONT WILL MOVE IN FOR FRIDAY NIGHT
THROUGH SATURDAY NIGHT. THIS WILL PROVIDE THE FOCUS FOR MORE
THUNDERSTORMS. DRY WEATHER SHOULD THEN RETURN FOR SUNDAY INTO
MONDAY.

&&

.AVIATION.../DISCUSSION FOR 311800Z TAFS/.

AS CONVECTIVE TEMPERATURES ARE BEING REACHED SCATTERED
THUNDERSTORMS ARE BREAKING OUT ACROSS THE NORTHERN PARTS OF
CENTRAL INDIANA. FORECAST SOUNDINGS REVEAL AN UNSTABLE ATMOSPHERE
ACROSS CENTRAL INDIANA AS THE COLD FRONT APPROACHES FROM ILLINOIS.
TIMING PROJECTIONS INDICATE THE MAIN LINE OF TSRA SHOULD ARRIVE
LATE THIS AFTERNOON ACROSS CENTRAL INDIANA...BUT MEANWHILE POP UP
CONVECTION WILL BE PRESENT AHEAD OF THE FRONT.

THUS WILL USE VCTS FOR THE POP UP CONVECTION THIS AFTERNOON AND
AMEND AS NECESSARY...AND TIME THE MAIN LINE OF STORMS THROUGH THE
TAF SITES IN A 2-3 HOUR WINDOW NEAR 00Z. MOST CEILINGS WILL REMAIN
VFR AS MOST CLOUD BASES ARE EXPECTED NEAR 4K FT. HOWEVER MVFR OR
BRIEF IFR CONDITIONS WILL BE POSSIBLE WITH ANY THUNDERSTORM.

CLEARING SKIES AND COOLER TEMPS EXPECTED IN THE WAKE OF THE COLD
FRONT AND WITH THE EXPECTED RAIN...MVFR FOG WILL BE A POSSIBILITY.
AS HEATING AND MIXING RESUMES ON TUESDAY MORNING...ANY FOG WILL
QUICKLY MIX OUT AND LEAD TO VFR CONDITIONS.

&&

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