What happened

The episode as NWS ILX wrote it up.

A deep area of low pressure lifting from the Plains into the Upper Midwest pulled a strong cold front eastward toward the Mississippi River during the afternoon of May 25th. Severe thunderstorms developed ahead of the cold front, as well as along a warm front lifting northward through the area. Many of the storms produced large hail up to the size of golf balls and damaging winds in excess of 60 mph. In addition, 6 tornadoes touched down across central Illinois, including an EF2 tornado that caused significant damage south of Robinson in Crawford County.

What forecasters said that day

The local office's own words before the first event, 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 the first event at May 25, 9:40 AM CST, 1 hour 42 minutes earlier.

ISSUED 330 AM CDT WED MAY 25 2011

FORECAST CONCERN IS MODERATE RISK OF SEVERE STORMS TODAY AND THIS
EVENING SOUTHEAST OF A QUINCY TO PEORIA TO PONTIAC LINE (SLIGHT RISK
OF SEVERE STORMS NW OF THIS LINE) AND ALSO HEAVY RAINS LIKELY TODAY.

00Z SHORT RANGE MODELS ARE IN FAIR AGREEMENT NEXT FEW DAYS AND USED
A BLEND. MET AND MAV GUIDANCE TEMPS HAVE TRENDED COOLER FROM TONIGHT
THROUGH THU NIGHT...AND TRENDED FORECAST IN THAT DIRECTION... THOUGH
NOT QUITE AS COOL ESPECIALLY FOR THU HIGHS.

SHORT TERM...TODAY THROUGH SATURDAY.

SPC ISSUED TORNADO WATCH FROM LINCOLN SW EARLY THIS MORNING FROM
1 TO 8 AM CDT. RADAR MOSAIC SHOWS A LING OF STRONG TO POTENTIALLY
SEVERE STORMS WITH HAIL AND GUSTY WINDS RACING NE AT 45 MPH FROM A
QUINCY TO LITCHFIELD LINE.

EARLY MORNING SURFACE MAP SHOWS DEEPENING 995 MB LOW PRESSURE OVER
CENTRAL KS WITH A FRONTAL BOUNDARY OVER NORTHERN MO INTO CENTRAL
IL/IN NEAR I-72 AND I-74. TEMPS HAVE SLIPPED INTO THE MID 50S
NORTH OF THE FRONT FROM GALESBURG...PEORIA AND BLOOMINGTON NORTH
WHILE UPPER 60S TO AROUND 70F FROM I-72 SOUTH WHERE DEWPOINTS IN
WARM SECTOR IN THE MID 60S. DEEPENING 556 DM 500 MB LOW WAS OVER
CENTRAL KS WITH WIDESPREAD CONVECTION AHEAD OF IT OVER IA...MO
INTO WESTERN IL.

MODELS TAKE SURFACE AND UPPER LEVEL LOW FROM CENTRAL KS INTO
CENTRAL MO BY SUNSET AND INTO CENTRAL IL BY THU MORNING.
WIDESPREAD CONVECTION EXPECTED NEAR AND AHEAD OF THIS FEATURE OVER
CENTRAL/SE IL THROUGH THU. ATMOSPHERE BECOME VERY UNSTABLE BY THIS
AFTERNOON ESPECIALLY WITH CAPES RISING TO 2000-3500 J/KG AND
HIGHEST SE OF THE IL RIVER WHERE MODERATE RISK OF SEVERE STORMS
LATER THIS AFTERNOON AND EVENING. ALSO HEAVY RAINS LOOK LIKELY
TODAY AND THIS EVENING. THOUGH FLASH FLOOD GUIDANCE VALUES FAIRLY
HIGH AROUND 3 INCHES IN 3 HOURS SO DID NOT ISSUE ANY FLOOD WATCHES
TODAY. ONE MORE DAY WITH HIGHS IN THE LOW TO MID 80S AND DEWPOINTS
IN THE 60S.

PER SPC DAY 1 OUTLOOK...A BROAD ZONE OF POTENTIALLY SIGNIFICANT
SEVERE WEATHER INCLUDING VERY LARGE HAIL 2 INCH DIAMETER OR
LARGER...WIDESPREAD DAMAGING WINDS...AND SCATTERED
STRONG/DAMAGING TORNADOES IS FORECAST ACROSS A REGION CENTERED
OVER THE MID MS/OH VALLEYS TODAY. AS CONVECTION OVER MO...EASTERN
IA AND WESTERN IL MOVES NE INTO THE SOUTHERN GREAT LAKES REGION
AND ACROSS THE OH VALLEY THROUGH MIDDAY...HEATING/DESTABILIZATION OF
THE PRE-CONVECTIVE AIRMASS SHOULD PERMIT REINTENSIFICATION/EXPANSION
OF STORMS ACROSS THIS REGION. MEANWHILE...STORM DEVELOPMENT IS
FORECAST TO OCCUR BY EARLY AFTERNOON IN A SECOND BAND FARTHER
WEST...DEVELOPING ACROSS MO JUST AHEAD OF THE UPPER SYSTEM...AND
THEN EXPANDING SWD ALONG THE SURFACE FRONT. WITH A VERY MOIST WARM
SECTOR AIRMASS...STRONG INSTABILITY IS EXPECTED TO DEVELOP BY THIS
AFTERNOON. WITH 70 KT MID LEVEL SWLY JET ACROSS THE MID MS/LOWER OH
VALLEY REGION ON SE FRINGE OF THE ASSOCIATED LOW...
SHEAR/INSTABILITY COMBINATION WILL FAVOR RAPID INTENSIFICATION OF
STORMS...WITH STORM MODE TO INCLUDE BOTH SUPERCELLS...AND RAPIDLY
MOVING/BOWING CLUSTERS. IN ADDITION TO STRONG MID LEVEL
MESOCYCLONES... LOW TROPOSPHERIC SHEAR WILL ALSO SUPPORT LOW LEVEL
ROTATION...AND THEREFORE POTENTIAL EXISTS FOR SEVERAL LARGE/STRONG
TORNADOES. DAMAGING WINDS ARE LIKEWISE EXPECTED -- PARTICULARLY NEAR
BOWING STORM CLUSTERS...AND LARGE HAIL IS ALSO LIKELY ACROSS THIS
REGION. THE SECOND/FRONTAL BAND OF STORMS SHOULD CROSS THE MS VALLEY
INTO EARLY EVENING... WITH SEVERE POTENTIAL ADVANCING EASTWARD
ACROSS THE OH VALLEY REGION THROUGH LATE EVENING.

SPC HAS MODERATE RISK OF SEVERE STORMS LATER THIS AFTERNOON AND
EVENING SE OF THE IL RIVER WITH SLIGHT RISK NW OF THE IL RIVER.
MODERATE RISK HAS 45% RISK OF LARGE HAIL (10% RISK OF 2 INCH OR
LARGER HAIL WITHIN 25 MILES OF A POINT)...15% RISK OF TORNADOES
(10% RISK OF STRONG TORNADOES EF2 OR STRONGER WITHIN 25 MILES OF A
POINT). ALSO HAVE 30% RISK OF DAMAGING WIND GUSTS ACROSS MUCH OF IL.

OCCASIONAL SHOWERS AND A FEW THUNDERSTORMS EXPECTED YET ON THU AND
MUCH COOLER HIGHS IN THE 60S. SPC HAS SLIGHT CHANCE OF SEVERE STORMS
EAST OF INDIANA ON THU. SHOWERS DIMINISH FROM WEST TO EAST DURING
THU NIGHT AS UPPER LEVEL LOW WEAKENS AND PULLS AWAY FROM IL WITH DRY
CONDITIONS PREVAILING FRI. BUT NEXT NORTHERN STREAM UPPER LEVEL LOW
DIGS INTO THE MIDWEST FRIDAY NIGHT INTO SAT BRINGING NEXT CHANCE OF
SHOWERS AND THUNDERSTORMS.

LONG TERM...SATURDAY NIGHT THROUGH WEDNESDAY.

FEW CHANGES MADE TO THE FORECAST EARLY NEXT WEEK WITH A VERY WARM
AND HUMID SUMMER-LIKE WEATHER PATTERN SETTING UP ACROSS CENTRAL AND
SE IL EARLY NEXT WEEK. THIS DUE TO STRONG UPPER LEVEL RIDGE
BUILDING NORTHWARD ACROSS THE EASTERN STATES WITH EXTENDING MODELS
LIKE 00Z ECMWF...UKMET AND GFS SHOWING A 595 DM 500 MB HIGH
OVER KY BY SUNSET MON. HIGHS IN THE MID TO UPPER 80S SUNDAY AND
UPPER 80S AND LOWER 90S MON-WED. HAVE SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS FROM PEORIA AND BLOOMINGTON NORTH SAT NIGHT THROUGH
SUNDAY NIGHT (30% CHANCE FROM GALESBURG TO LACON NORTH SAT NIGHT)
DUE TO UPPER LEVEL DISTURBANCE RIDING OVER THE TOP OF THE
RIDGE...BUT BEST CHANCES OF CONVECTION APPEAR TO BE OVER NORTHERN
IL UP NORTH INTO IA AND WI.
