NWS Lincoln, IL wrote its last area forecast discussion before the first event at Jun 18, 11:40 AM CST, 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 1240 PM CDT THU JUN 18 2015 .UPDATE... ISSUED AT 1040 AM CDT THU JUN 18 2015 UPDATED THE FORECAST TO REMOVE THE PATCHY DENSE FOG THIS MORNING WHICH LIFTED DURING MID MORNING. OTHERWISE FORECAST LOOKS ON TRACK TODAY AS CHANCES OF SHOWERS AND THUNDERSTORMS INCREASES DURING THE REST OF THE DAY...ESPECIALLY THIS AFTERNOON FROM I-72 SOUTH WHERE LIKELY CHANCES CONTINUE. KILX 12Z SOUNDING SHOWS PRECIPITABLE WATER VALUE OF 1.52 INCHES AND NAM FORECAST THESE VALUES TO INCREASE BETWEEN 1.50-2.25 INCHES DURING THE AFTERNOON FROM IL RIVER SOUTHEAST. SO THUNDERSTORMS COULD PRODUCE LOCALLY HEAVY RAINS FROM IL RIVER SOUTHEAST. SPC HAS SLIGHT RISK EAST OF IL OVER IN/OH WHERE BETTER INSTABLITY WILL BE FOR MAINLY DAMAGING WIND GUSTS FROM WET MICROBURSTS. BUT MARGINAL RISK EXIST FROM ALONG THE IL RIVER SOUTHEAST THIS AFTERNOON AND EVENING FOR GUSTY WINDS AND SMALL HAIL. REMNANTS OF FORMER TROPICAL STORM BILL OVER EASTERN OK WHERE 580 DM 500 MB LOW IS...WILL TRACK SLOWLY ENE INTO THE OZARKS OF NW AR BY MIDNIGHT TONIGHT AND INCREASE CHANCES OF SHOWERS AND THUNDERSTORMS AHEAD OF IT INTO CENTRAL AND ESPECIALLY SOUTHEAST IL THROUGH FRI NIGHT.

WITH MOISTURE FROM THE REMNANTS OF TROPICAL STORM BILL FLOWING NORTHEASTWARD AND A WEAK COLD FRONT DROPPING INTO THE NORTHWEST KILX CWA TODAY...THINK SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP AS THE DAY PROGRESSES. 06Z NAM INDICATES FRONT WILL REACH A BLOOMINGTON TO RUSHVILLE LINE BY LATE AFTERNOON...ESSENTIALLY ENDING ANY RAIN CHANCES TO THE NORTH. FURTHER SOUTH...HIGHEST POPS APPEAR TO BE CONCENTRATED ON BOTH THE NAM AND HRRR ALONG/SOUTHEAST OF A CHAMPAIGN TO SPRINGFIELD LINE. .LONG TERM...(TONIGHT THROUGH WEDNESDAY) ISSUED AT 329 AM CDT THU JUN 18 2015 MAIN FORECAST CONCERN CONTINUES TO BE THE TRACK OF BILL AND THE POTENTIAL FOR ANOTHER ROUND OF HEAVY RAIN ACROSS PARTS OF THE KILX CWA. 00Z JUNE 18 MODELS ARE IN RELATIVELY GOOD AGREEMENT...SHOWING A FURTHER SOUTH TRACK AND A MORE COMPACT AREA OF ASSOCIATED PRECIP. MODEL CONSENSUS TAKES SURFACE LOW PRESSURE FROM EASTERN OKLAHOMA THIS EVENING...TO THE OZARKS BY FRIDAY EVENING...THEN INTO SOUTHERN INDIANA BY SATURDAY. GIVEN THIS PARTICULAR TRACK...THE SOUTHEAST CWA WILL BE FAVORED FOR THE HEAVIEST RAIN FROM TONIGHT THROUGH SATURDAY MORNING. BASED ON MODEL TRENDS AND THE PRESENCE OF SUBSIDENCE/DRYING ON THE N/NW SIDE OF THE APPROACHING SYSTEM...HAVE ADJUSTED POPS ACCORDINGLY. HAVE FOCUSED LIKELY TO CATEGORICAL POPS ALONG/SOUTH OF I-70...WITH CHANCE POPS AS FAR NORTHWEST AS THE ILLINOIS RIVER. FURTHER NORTHWEST...HAVE GENERALLY GONE WITH A DRY FORECAST IN THE GALESBURG/LACON AREAS THROUGH SATURDAY. WITH UNSEASONABLY HIGH PRECIPITABLE WATER VALUES AROUND 2 INCHES...ANY STORMS THAT OCCUR DURING THIS PERIOD WILL BE CAPABLE OF VERY HIGH RAINFALL RATES AND LOCALIZED FLASH FLOODING. EXPECTED RAINFALL TOTALS WILL GENERALLY BE IN THE 2 TO 2.50 RANGE SOUTH OF I- 70...ALTHOUGH ISOLATED HIGHER AMOUNTS WILL BE LIKELY. DESPITE EXPECTED HEAVY RAINFALL...OPTED NOT TO ISSUE A FLASH FLOOD WATCH AT THIS TIME...MAINLY DUE TO THE FACT THAT THIS AREA MISSED THE HEAVIEST RAINFALL FROM A COUPLE DAYS AGO. THERE ARE ALSO SOME SIGNS THAT THE SYSTEM COULD TRACK EVEN FURTHER SOUTH...SHIFTING THE HEAVIEST RAINFALL AXIS JUST SOUTH OF THE CWA. ONCE BILL DEPARTS...LINGERING MORNING RAIN ACROSS THE E/SE WILL COME TO AN END BY MIDDAY SATURDAY...FOLLOWED BY HOT AND DRY CONDITIONS ACROSS THE BOARD SATURDAY AFTERNOON. COLD FRONT WILL THEN APPROACH FROM THE NORTHWEST SATURDAY NIGHT INTO SUNDAY...BRINGING RAIN CHANCES BACK INTO THE PICTURE.

HAVE INCLUDED LOW CHANCE POPS ACCORDINGLY. HAVE TEMPORARILY PUSHED POPS NORTH OF THE AREA BY WEDNESDAY AS RIDGE BECOMES MOST DOMINANT...BEFORE IT BREAKS DOWN AND FRONT SAGS BACK SOUTHWARD BY THE END OF NEXT WEEK. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON) ISSUED AT 1240 PM CDT THU JUN 18 2015 A STRONG LINE OF THUNDERSTORMS THAT RECENTLY MOVED THROUGH SPI AND DEC WITH DEC HAVING WIND GUST OF 48 MPH AT 1716Z/1216 PM WILL LIFT QUICKLY NE TOWARD CMI IN ABOUT AN HOUR.

The Lincoln radar (KILX), 92 km away, was scanning. The volume nearest the first event began at 18:04 UTC.
3 flash flood, 1 thunderstorm wind. Local standard time, as filed.
Numerous 4 to 6-inch diameter tree branches were blown down across Champaign.
A band of thunderstorms produced nearly 3.00 of rain in less than two hours in extreme northern McLean County during the afternoon of June 18th. This resulted in rapid flash flooding of rural roads, which persisted until early evening.
Flash flooding developed rapidly during the afternoon of June 18th due to already saturated ground and rainfall of close to 3.00. Many rural roads in central and eastern Woodford were impassable until early evening. A section of railroad track of the Toledo, Peoria and Western Railway east of Eureka was washed out.
A thunderstorm produced heavy rain amounts of 1.50 in 30 minutes across central Clay County. This combined with already saturated ground to produce rapid flash flooding of several roadways. Sheriff's Department officials reported more than six inches of flowing water across parts of U.S. Highway 45 south of Louisville.
