Severe thunderstorms developed across central Illinois the afternoon of June 13, continuing through the evening.  Areas along and south of a Macomb to Bloomington line were most affected by these storms.  After the initial storms exited the state in the mid to late evening hours, more developed in western Illinois late in the evening, crossing the state through the night.

National surface map at 7 am CDT The national weather map at 7 am CDT showed a strong low pressure center across Nebraska.  This was forecast to move northeast toward the upper Great Lakes region, with warm and unstable air over much of the Midwest.  The main question was whether cloudiness from overnight storms across Missouri would hamper the development of severe weather.
Forecast of severe wind (>= 58 mph)
Forecast of large hail (3/4 inch or greater)
The two graphics at the left show the probabilities of wind damage (top) and large hail (bottom), as indicated in the Storm Prediction Center's forecast for Day 1 (in this case, 11:30 AM  Monday through 7 AM Tuesday).  In the top graphic, the hatched area indicates a 10% or greater probability of wind speeds of 75 mph or greater.  The hatched region in the lower graphic indicates a 10% or greater probability of hail of at least 2 inches in diameter.
Lincoln radar image, 3:12 PM The Lincoln radar image at 3:12 PM showed all was quiet over the immediate central Illinois area.  Strong to severe thunderstorms had developed across south central Illinois, between St. Louis and Vandalia.
Lincoln radar image, 4:04 PM At 4:04 PM, radar showed a supercell thunderstorm developing over west central Illinois, between Quincy and Macomb.  This thunderstorm would produce half dollar size hail in Huntsville, in Schuyler County, around 4:15 PM.
Lincoln radar image, 5:08 PM A little over an hour later (5:08 PM), the thunderstorm in west central Illinois had moved into Fulton County, where hail of half dollar to golfball-size was reported around Lewistown, breaking windows in several vehicles.  Further south, strong to severe thunderstorms were increasing in areas between Quincy and St. Louis, with a supercell thunderstorm west of Carlinville.
Lincoln radar image at 5:59 PM The radar image at 6 PM showed severe thunderstorms in a line from Jacksonville south to St. Louis.  Several trees were damaged or brought down across Scott and Morgan Counties
Lincoln radar image, 6:09 PM At 6:09 PM, the storms were beginning to move into Sangamon County.  Notice the S-shape in the radar echoes west of Springfield.  This can indicate the potential for strong winds.
Lincoln radar image at 6:29 PM Around 6:30 PM, the storms were moving through the Springfield area, causing extensive damage to trees and power lines in Chatham, Springfield, and Rochester.
Lincoln radar image at 7:08 PM At 7:08 PM, the storms were moving through the heart of De Witt, Macon, and Christian Counties.  The strong winds continued, causing several buildings in Latham to lose their roof, as well as one in Decatur; damage to a grain bin in Hallsville; and extensive tree and power line damage.  Measured wind gusts around this time included 59 mph 7 miles northeast of Lincoln (6:55 PM), 70 mph at Elwin at 7 PM, and 58 mph at the Decatur Airport at 7:06 PM.
Lincoln radar image at 7:48 PM At 7:48 PM, radar showed the squall line pushing across eastern and south central Illinois.  A measured wind gust of 65 mph was reported 2 miles east of Urbana at this time. 
Lincoln radar image at 9:37 PM At 9:37 PM, the original squall line had mostly pushed into Indiana, but strong storms were still occurring between Effingham and Terre Haute.  Meanwhile, the next batch of strong to severe storms was beginning to develop north of St. Louis.
Lincoln radar image at 10:43 PM This radar image at 10:43 PM showed a bow echo (a line of thunderstorms bulging in the middle) moving across Macoupin and Sangamon Counties.
Lincoln radar image at 11:58 PM By midnight, strong to severe thunderstorms were again in a crooked line from Decatur to St. Louis. 
Radar estimated rainfall through 5 AM Tuesday
Observed rainfall, June 13-14
Some much-needed rainfall occurred across portions of central Illinois.  The highest amounts were mainly south of I-72, especially from Alton northeast through Decatur to near Champaign.  The top image shows the radar estimated rainfall as of about 5 AM Tuesday morning.  The radar estimated about 2.5 to 4 inches of rain in these areas (yellow to orange shading).  Radar totals can occasionally be overestimated due to the occurrence of hail; the bottom image shows specific rainfall observations about a half inch lower than the radar estimate.

The path of the supercell that caused the large hail in west central Illinois is also visible in the radar estimated rainfall image, indicated by the dark blue line from Quincy to Peoria.
