The episode as NWS ILX wrote it up.

A potent upper-level disturbance interacting with a slow-moving cold front triggered clusters of severe thunderstorms across central Illinois during the afternoon of July 19th. Many of the storms produced large hail and damaging wind gusts...mainly along and south of a Rushville...to Lincoln...to Paris line. The most intense wind damage caused by downburts occurred across parts of Christian, Shelby, and Moultrie counties...from Taylorville eastward to Sullivan. Widespread wind damage was reported along this path.

ISSUED 233 AM CDT MON JUL 19 2010

AN EXTENDED PERIOD OF UNSETTLED WEATHER IS IN STORE THROUGH AT LEAST
THURSDAY AS A FRONTAL BOUNDARY STALLS ACROSS CENTRAL ILLINOIS.

06Z SURFACE ANALYSIS SHOWS SLOW-MOVING COLD FRONT BISECTING THE KILX
CWA...WITH OBS INDICATING IT HAS PUSHED JUST EAST OF I-55. BEHIND
THE FRONT...SLIGHTLY DRIER AIR HAS TRICKLED INTO THE ILLINOIS RIVER
VALLEY AS EVIDENCED BY DEWPOINTS DROPPING INTO THE UPPER 60S.
ALOFT...RIDGE REMAINS IN PLACE ACROSS THE DESERT SOUTHWEST/SOUTHERN
PLAINS...WHILE FAST ZONAL FLOW PERSISTS ALONG THE U.S./CANADIAN
BORDER.

SHORT TERM...TODAY THROUGH WEDNESDAY
QUIET WEATHER APPEARS TO BE ON TAP FOR TODAY...AS A WEAK BUBBLE OF
HIGH PRESSURE MOVES OVERHEAD AND FRONT GETS SUPPRESSED TO ALONG OR
JUST SOUTH OF I-70. FORECAST SOUNDINGS SHOW DECENT CAP IN PLACE DUE
TO SUBSIDENCE INVERSION AT AROUND 850MB...SO THINK CONDITIONS WILL
REMAIN DRY ACROSS MOST OF CENTRAL ILLINOIS. THE EXCEPTION MAY BE
ACROSS THE FAR SOUTH...WHERE CAP WILL BE WEAKER AND FRONTAL BOUNDARY
WILL BE NEARBY. HAVE THEREFORE INCLUDED LOW CHANCE POPS ALONG AND
SOUTH OF I-70 FOR THE AFTERNOON.

UPPER-LEVEL WAVE CURRENTLY ACROSS MONTANA/WYOMING WILL TRACK E/SE
TODAY...TRIGGERING A COMPLEX OF STRONG TO SEVERE THUNDERSTORMS
ACROSS THE DAKOTAS. THESE STORMS WILL TEND TO PUSH E/SE ALONG THE
PERIPHERY OF A VERY UNSTABLE INFLOW AIRMASS ACROSS THE PLAINS...
REACHING IOWA BY THIS AFTERNOON. 00Z 19 JUL MODELS ARE ALL IN
RELATIVELY GOOD AGREEMENT WITH THE TRACK AND TIMING OF THE STORMS
INTO NORTH-CENTRAL ILLINOIS THIS EVENING...WITH THE EXCEPTION OF THE
GFS WHICH HAS A MORE EASTERLY TRAJECTORY INTO NORTHERN ILLINOIS.
SINCE GFS HAS BEEN PERFORMING QUITE POORLY RECENTLY...HAVE REJECTED
ITS SOLUTION IN FAVOR OF THE NAM12.

WITH 45-50KT LLJ DEVELOPING FROM THE PLAINS E/NE INTO WESTERN
ILLINOIS BY 06Z...CONVECTION WILL REMAIN QUITE ROBUST AS IT CROSSES
THE MISSISSIPPI RIVER INTO ILLINOIS DURING THE EVENING. FAVORABLE
INFLOW AND 0-6KM BULK SHEAR VALUES IN EXCESS OF 40...SUGGEST A
DAMAGING WIND THREAT. HEAVY RAINFALL ALSO A GOOD BET...AS
PRECIPITABLE WATER VALUES EXCEED 2 INCHES AND 850MB THETA-E AXIS
SETS UP FROM TEXAS N/NE INTO CENTRAL ILLINOIS. HAVE BUMPED UP POPS
ACCORDINGLY AND MENTIONED HEAVY RAIN THREAT ACROSS THE NORTHERN HALF
OF THE CWA TONIGHT. FURTHER SOUTH...WENT WITH HIGH CHANCE POPS SOUTH
OF A SPRINGFIELD TO MATTOON LINE.

OVERNIGHT MCS WILL EXIT THE REGION EARLY TUESDAY MORNING...HOWEVER
EFFECTIVE BOUNDARY WILL BE LEFT BEHIND RIGHT ACROSS THE HEART OF
CENTRAL ILLINOIS. WITH UPPER PATTERN REMAINING UNCHANGED...THINK
BOUNDARY WILL REMAIN STATIONARY THROUGH AT LEAST MID-WEEK. HAVE
THEREFORE INCREASED POPS TO 40 ACROSS THE BOARD FOR BOTH TUESDAY AND
WEDNESDAY...AS ADDITIONAL SHOWERS/STORMS DEVELOP ALONG THE BOUNDARY
IN THE WARM/HUMID AIRMASS.

LONG TERM...THURSDAY THROUGH SUNDAY
DID NOT MAKE TOO MANY CHANGES IN THE EXTENDED...OTHER THAN TO
CONTINUE LOW CHANCE POPS INTO THURSDAY...AS SOUTHERN CONUS RIDGE
STRUGGLES TO BUILD NORTHWARD. PERSISTENT FRONTAL BOUNDARY WILL
SLOWLY SHIFT NORTHWARD ACCORDINGLY...BUT WILL LIKELY BE SUPPRESSED
FURTHER SOUTHWARD THAN MOST MODEL SOLUTIONS DUE TO CONVECTION. THINK
FRIDAY LOOKS LIKE THE DRIEST...AND HOTTEST...DAY OF THE WEEK BEFORE
ANOTHER WAVE AND ACCOMPANYING FRONT APPROACH BY SATURDAY.
