What happened

The episode as NWS ILX wrote it up.

Excessive rainfall during the middle of April led to widespread flooding across a large part of northern and central Illinois. Locations from the Chicago metro area, southwest along the Illinois River Valley, received 5 to 10 inches over a two day period from the 17-18th. This heavy rain event combined with moisture laden soils from moderate to heavy rain between April 10th and the 16th, and resulted in record flooding along the Illinois and Spoon Rivers in central Illinois.

The record flooding did significant damage to locations along and near the river banks. Every county along the Illinois River was declared a state and federal disaster area.

High impact flooding on the Illinois River continued into the month of May 2013.

What forecasters said that day

.DISCUSSION...
ISSUED 820 PM CDT WED APR 17 2013

ACTIVE WEATHER EXPECTED TO CONTINUE OVER AT LEAST THE NORTHWEST
HALF OF THE FORECAST AREA TONIGHT. OUTFLOW BOUNDARY FROM CONVECTION
THAT OCCURRED THIS AFTERNOON ACROSS THE NORTH HAS SPREAD TO JUST
SOUTH OF LITCHFIELD EARLY THIS EVENING. TEMPERATURES TO THE NORTH
OF THE BOUNDARY WERE IN THE MID 40S TO LOWER 50S...WHILE SOUTH
OF THE FRONT...READINGS WERE WELL INTO THE 70S WITH DEW POINTS IN
THE 60S. SEVERAL SUPERCELLS AFFECTING PARTS OF WEST CENTRAL IL AT
THIS TIME WERE TRACKING NORTHEAST AND WILL AFFECT PART OF THE
ILLINOIS RIVER VALLEY WITH ADDITIONAL HEAVY RAIN...HAIL AND ISOLATED
DAMAGING WINDS OVER THE NEXT FEW HOURS. ADDITIONAL RAINFALL ACROSS
THE NORTHWEST HALF WILL TOTAL 1 TO 2 INCHES...ON TOP OF THE 1 TO
2 INCHES FROM THIS MORNING. THE HEADLINES FOR FLOODING WILL REMAIN
IN PLACE.

LOOKING FURTHER SOUTHWEST...ADDITIONAL SHOWERS AND THUNDERSTORMS
WERE DEVELOPING OVER PARTS OF EASTERN KS INTO SOUTHWEST MISSOURI
AND WILL CONTINUE TO TRACK NORTHEAST AHEAD OF THE STRONG COLD FRONT
WHICH IS SLATED TO SWEEP ACROSS OUR AREA TOMORROW EVENING. OTHER
THAN FIGHTING THE HOURLY TEMPERATURES IN THE GRIDS...ESPECIALLY
NORTH OF THE OUTFLOW BOUNDARY...THE REST OF THE FORECAST IS IN GOOD
SHAPE...SO NO UPDATE IS NEEDED AT THIS TIME.

.AVIATION...
ISSUED 1120 PM CDT WED APR 17 2013

LITTLE CHANGE FROM PREVIOUS THINKING. THE MAIN FORECAST CHALLENGE
WILL BE COVERAGE OF SHOWERS AND THUNDERSTORMS AS A COLD FRONT
OUT TO OUR WEST SLOWLY PUSHES TOWARDS THE AREA DURING THE DAY
THURSDAY. WARM FRONT TO OUR SOUTH WAS SLOWLY LIFTING NORTH
OVER PARTS OF SOUTH CENTRAL ILLINOIS LATE THIS EVENING WITH
MOSTLY MVFR AND IFR CIGS TO THE NORTH...AND VFR CIGS JUST
SOUTH OF THE BOUNDARY. WILL CONTINUE TO HOLD ON TO THE MVFR
AND IFR CIGS OVER MOST OF THE AREA AND THEN TREND FURTHER
NORTH WITH THE FRONT LATE TONIGHT. MAIN BAND OF SHOWERS AND
THUNDERSTORMS HAS BEEN OCCURRING WEST OF I-55 FOR THE MOST
PART THIS EVENING...BUT EXPECT A GRADUAL EASTWARD SHIFT
LATE TONIGHT. SFC WINDS WILL GRADUALLY VEER MORE INTO A
SOUTHEAST DIRECTION MOST AREAS BY LATER TONIGHT...AND THEN
INTO THE SOUTH THURSDAY MORNING...AND FINALLY INTO THE
SOUTHWEST BY AFTERNOON JUST AHEAD OF THE FRONT. WIND
SPEEDS WILL AVERAGE FROM 12 TO 17 KTS TONIGHT AND INCREASE
TO BETWEEN 20 AND 25 KTS ON THURSDAY WITH GUSTS AROUND 35 KTS
AT TIMES. JUST AFTR FROPA...WINDS WILL SWITCH INTO THE WEST
LATE TOMORROW AFTN MOST AREAS WITH MAINLY MVFR CIGS EXPCTD
THU NIGHT.

.PREV DISCUSSION...
ISSUED 322 PM CDT WED APR 17 2013

SHORT TERM...TONIGHT THROUGH SUNDAY...A WARM FRONT HAS LIFTED
INTO CENTRAL ILLINOIS AND WILL HELP SERVE AS A FOCUS FOR SHOWER
AND THUNDERSTORM DEVELOPMENT THROUGH THE NIGHT AND EARLY THURSDAY.
THE SHOWERS/STORMS INITIALLY WILL BE MOST NUMEROUS ALONG/NORTH OF
THE BOUNDARY...AS WILL THE HEAVIEST RAINFALL. THESE STORMS HAVE
THE POTENTIAL TO BE SEVERE...WITH LARGE HAIL AND DAMAGING WINDS
THE PRIMARY THREATS. A TORNADO CAN NOT BE RULED OUT IN THE
ENHANCED SHEAR RIGHT ALONG THE WARM FRONT. PLAN TO KEEP THE FLASH
FLOOD WATCH GOING EVERYWHERE NORTH OF THE I-70 CORRIDOR...WHERE
THE MOST RAIN HAS FALLEN RECENTLY AND FLASH FLOOD GUIDANCE IS
LOWEST. PRECIPITABLE WATER VALUES AROUND 1.5 INCHES AREAWIDE
SHOULD ENSURE EFFICIENT RAINFALL PRODUCTION UNTIL THE SYSTEM
DEPARTS LATER THURSDAY

THE GREATER RISK FOR WIDESPREAD SEVERE WEATHER ACROSS THE WILL
OCCUR THURSDAY ALONG/AHEAD OF A STRONG COLD FRONT. THE FRONT WILL
SWEEP WEST/EAST THROUGH THE FORECAST AREA FROM MIDDAY INTO EARLY
EVENING. MODERATE CAPE VALUES OF 1500-2000 J/KG AND IMPRESSIVE
BULK SHEAR VALUES OF 50+ KTS SUPPORT SIGNIFICANT STORM
DEVELOPMENT...WITH DAMAGING WIND GUSTS LIKELY AND A FEW TORNADOES
POSSIBLE. STRONG SOUTHERLY WINDS CAN ALSO BE EXPECTED AHEAD OF THE
FRONT AS A PORTION OF THE 70+ KT 850 JET MIXES DOWN...ESPECIALLY
IN EASTERN SECTIONS OF THE FORECAST AREA. MANY AREAS WILL LIKELY
SEE ADVISORY CRITERIA WINDS DURING THE DAY THURSDAY...BUT OPTED
AGAINST AN ADVISORY DUE TO THE EXPECTED SEVERE WEATHER HEADLINES
THAT SHOULD BE IN EFFECT...IN ADDITION TO THE FLASH FLOOD WATCH.
WANTED TO MINIMIZE HEADLINES WHERE POSSIBLE TO MINIMIZE HEADLINE
CONFUSION/OVERLOAD.

THE PRECIPITATION WILL TAPER OFF THURSDAY NIGHT INTO EARLY FRIDAY
AS THE SYSTEM PULLS AWAY AND MUCH COLDER AIR SETTLES INTO THE
REGION. QUIET BUT COOL WEATHER WEATHER SHOULD THEN LAST THROUGH
MOST OF THE WEEKEND WITH NEUTRAL UPPER FLOW AND A SURFACE HIGH IN
PLACE.

LONG TERM...MONDAY THROUGH WEDNESDAY...MULTIPLE IMPULSES DIVING
IN THE NORTHWEST UPPER LEVEL FLOW WILL CARVE OUT A BROAD TROF OVER
THE LOWER 48 STATES DURING THE PERIOD. THE TROFFING/IMPULSES MAY
POSE A PERIODIC RISK OF SHOWERS/STORMS LOCALLY...BUT MODEL
AGREEMENT ON THE DETAILS IS LOW. FOR THIS REASON...HAVE KEPT POPS
LOW AS WELL.
