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, 0.4 hours before the alert went out and 149 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 Lincoln, IL wrote its last area forecast discussion before this flash flood warning went out at Sep 20, 6:36 PM CDT, 49 minutes earlier.

Area forecast discussion, Sep 20, 6:36 PM CDT, 49 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
636 PM CDT SUN SEP 20 2009

.DISCUSSION...
ISSUED 246 PM CDT SUN SEP 20 2009

MAIN CONCERN CONTINUES TO BE CHANCES OF PCPN THROUGH ENTIRE
FORECAST PACKAGE. NAM-WRF AND GFS HAVE FINALLY GOTTEN A HANDLE ON
CURRENT SITUATION...SO CONFIDENCE IS NOW MUCH HIGHER THAN WITH
PREVIOUS FORECASTS. LONG TERM MODELS ARE COMING INTO BETTER
AGREEMENT WITH THE UPPER LVL SYSTEM MOVING ACROSS THE
AREA...HOWEVER THERE ARE STILL SOME TIMING DIFFERENCES. ECMWF
APPEARS IN BETTER AGREEMENT AND HAS BETTER CONTINUITY THAN THE
GFS. ECMWF ALSO AGREES WELL WITH CANADIAN AND SO WILL FOLLOW A
BLEND HERE.

SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT

CURRENT PCPN HAS LEFT A NICE SWATH OF HEAVY RAINFALL IN WESTERN
PARTS OF THE CWA. HEAVIEST RAINFALL HAS BEEN WEST OF SPI EXTENDING
FROM SOUTH OF JACKSONVILLE (IJX) TO THE ILLINOIS RIVER SOUTHWEST OF
PIA. HIGHEST AMOUNTS HAVE BEEN NEAR IJX BETWEEN 3.5 AND 5 INCHES.
THE AREA OF PCPN THAT CAUSED THE HEAVY RAINFALL APPEARS (BASED ON
RADAR AND SATELLITE) TO HAVE WEAKENED SOMEWHAT OVER LAST COUPLE
OF HOURS AS IT HAS MOVED NORTH. HOWEVER...ADDITIONAL PCPN WILL
CONTINUE THIS EVENING IN THE NORTH WITH SCATTERED PCPN IN THE
EAST. MODEL TREND IS FOR MOST OF PCPN TO END BEFORE MIDNIGHT WITH
SMALL CHANCES IN THE EAST AFTER MIDNIGHT. WITH ALL THE MOISTURE ON
THE SFC AND LIGHT WINDS TONIGHT...CONDITIONS ARE FAVORABLE FOR FOG
FORMATION OVER AREAS THAT RECEIVED THE RAINFALL. SO HAVE INCLUDED
MENTION OF AREAS FOG IN THE WEST AND PATCHY FOG IN THE EAST FOR
OVERNIGHT. THIS SYSTEM WILL MOVE EAST OVERNIGHT AND ILX CWA SHOULD
BE IN BETWEEN SYSTEMS TOMORROW...GIVING A DRY FORECAST.
HOWEVER...WILL KEEP SCHC IN THE GRIDS FOR TOMORROW.

THE MODELS THEN CONTINUE WITH A DEVELOPING CUTOFF SYSTEM IN THE
PLAINS WITH A RESULTING SFC FRONT WEST OF THE AREA. SOME PCPN IS
POSSIBLE IN WESTERN IL TOMORROW NIGHT AS THE FRONT SLOWLY MOVES
INTO THE REGION. THE FRONT WILL MOVE INTO THE STATE ON MAKE SLOW
PROGRESS EASTWARD THROUGH WED. THEREFORE PCPN CHANCES WILL
CONTINUE INTO WED WITH HIGHEST CHCS TUE WHEN FRONT FIRST ENTERS
THE CWA. CHANCES WILL DECREASE TUE NIGHT AND WED AS THE FORCING
ALONG THE FRONT WEAKENS. NAM-WRF INDICATES A SECONDARY LOW SYSTEM
ON THE FRONT THAT MOVES UP INTO IL WED AND WED NIGHT. GFS DOES NOT
HAVE THIS AND AM NOT SURE ABOUT THIS DETAIL JUST YET SO WILL KEEP
SCHC POPS IN THE GRIDS FOR WED NIGHT FOR NOW.

GUIDANCE TEMPS AGAIN LOOK ON THE WARM SIDE WITH PCPN FORECAST AND
LOTS OF CLOUD COVER. DECREASED GUIDANCE TEMPS DURING THE DAY BY
UP TO 5-6 DEGREES FOR TUE AND WED.

LONG TERM...THURSDAY THROUGH SUNDAY

GFS REMAINS OUT TO LUNCH WITH TIMING AND HANDLING OF THE CUTOFF
LOW IN THE PLAINS. ECMWF AND CANADIAN LOOK BETTER. SO SHOULD BE A
LULL IN PCPN CHANCES THUR AND THUR NIGHT BUT THEN START TO PICK UP
AGAIN FOR FRIDAY THROUGH SATURDAY. ANOTHER FRONTAL SYSTEM WILL
BEGIN TO PUSH INTO THE WESTERN IL FRI INCREASING MOISTURE
ADVECTION FROM THE GULF...THEREBY BRINGING THE RETURN OF PCPN TO
THE CWA. THE CUTOFF SYSTEM AND ASSOCIATED SFC LOW WILL SLOWLY MOVE
ENE ACROSS THE AREA WITH PCPN CHANCES CONTINUING INTO FRIDAY NIGHT
AND SATURDAY. AS THE SYSTEM THEN GETS CAUGHT UP IN THE MID LEVEL
PATTERN...PCPN CHANCES SHOULD DECREASE FOR SAT NIGHT AND SUNDAY.

MEX GUIDANCE TEMPS STILL TOO WARM GIVEN AMOUNT OF CLOUD COVER AND
PCPN FORECAST THROUGH THE PERIOD. A DECREASE OF 6+ DEGREES WAS
AGAIN WARRANTED FOR THUR THROUGH FRIDAY. SAT AND SUNDAY GUIDANCE
LOOKED OK FOR NOW.

.AVIATION...
ISSUED 636 PM CDT SUN SEP 20 2009...FOR THE 00Z TAFS

THE MESO VORTEX THAT TRIGGERED TODAYS WAVE OF LOCALLY HEAVY RAINS
HAS LIFTING NORTH OF THE CWA. A LINGERING BAND OF PRECIP IN THE SE
COUNTIES SHOULD REMAIN SE OF OUR TAF SITES.

A FEW SHOWERS OR SOME LIGHT DRIZZLE WILL BE POSSIBLE FOR A FEW
MORE HOURS BEHIND THE MESO LOW...FOR THE TAF SITES OF PIA/BMI/CMI.
WILL KEEP A VCSH IN PLACE FOR THE NEXT FEW HOURS.

SHORT TERM CONCERNS ARE POTENTIAL FOR VLIFR VIS/CIG FOR BMI THIS
EVENING...THEN A RETURN TO VLIFR FOG/CIG FOR LATE TONIGHT. WESTERN
CWA WILL HAVE A BETTER CHANCE OF DENSE FOG...WHERE THE HEAVIER
RAINS FELL. WILL INCLUDE TEMPOS FOR VLIFR VIS/CIG BTWN 11Z-13Z FOR
SPI/PIA.

FORECAST SOUNDING SHOW SOME CLEARING DEVELOPING FROM WEST TO EAST
ON MONDAY. CLEARING SHOULD REACH SPI BY 16Z...AND PROGRESS
EASTWARD IN THE AFTERNOON.
