The following events were reported: Flash Flood, Lightning, Thunderstorm Wind, Tornado. These occurred near station USW00014819, approximately 24.7672 km away, between 2014-06-30 18:01:00 and 2014-06-30 23:59:00.The events resulted in 1 injuries and 0 fatalities. The events caused property damage valued at 810000.0 and crop damage of 0.0. Episode Narrative: Extensive damage was sustained from two separate lines of thunderstorms on Monday, June 30th which was officially determined to be from two separate derecho events from Central Iowa east into Michigan and Ohio. Thunderstorms developed over Iowa during the early afternoon and organized into a forward-propagating quasi-linear convective system (QLCS) and tracked to southern Lake Michigan by early to mid evening. Meanwhile, a second complex of intense thunderstorms developed over central and eastern Iowa and also evolved into a QLCS, tracking across northern Illinois and northwest Indiana late in the evening into the overnight hours. ||Across northern Illinois and northwest Indiana, the first derecho event produced scattered straight-line wind damage, with gusts measured as high as 70 MPH. The second derecho produced far more extensive damage, with 80 to 90 MPH straight line winds and numerous tornadoes. Initial post-event surveys cataloged 18 tornadoes across northern Illinois and northwest Indiana, 17 of EF1 intensity and one of EF0 intensity. Of these 18 tornadoes, 14 were associated with a pair of large mesovortices that traveled along the Kankakee River Valley in Kankakee County, Illinois and Lake, Newton, and Jasper Counties in Indiana. ||Analysis of Google Earth satellite imagery gathered in spring of 2015 showed numerous additional areas of damage not documented in the original survey efforts. A thorough analysis of this imagery and synthesis with the original survey information led to a complete reanalysis of the Kankakee Valley tornadoes. Ultimately, 18 tornado tracks were identified alone in the Kankakee Valley, leading to a total of 22 tornadoes for northern Illinois and northwest Indiana. Of the 18 revised tornadoes, 16 of the paths were determined, in part, using satellite imagery. Further re-examination of the damage also led to a change in rating for several of the damage locations. Of the 18 reanalyzed Kankakee Valley tracks, two were rated EF2, 13 were rated EF1, and three were rated EF0. Additional details on this reanalysis, including the methods used, can be found in the Electronic Journal of Severe Storms Meteorology (Lyza et al. 2019, ���A Multi-Platform Reanalysis of the Kankakee Valley Tornado Cluster on 30 June 2014���). Extensive damage was sustained from two separate lines of thunderstorms on Monday, June 30th which was officially determined to be from two separate derecho events from Central Iowa east into Michigan and Ohio. Event Narrative: An NWS Storm Survey confirmed scattered straight-line wind damage across Romeoville consistent with 70 to 90 mph winds. Large tree limbs were blown down and an evergreen tree was snapped at its base along Marquette Drive and Enterprise Drive. A large metal street light was broken at its base and leaning on power lines near Romeo Road and Route 53. Multiple trees were blown down west of Route 53 partially blocking Belmont Drive. Power lines were down at Romeo Road and Macon Avenue. A tree was blown down blocking Homer Avenue. Portions of Route 53 were closed due to power lines down across the road north of Normantown Road. Minor roof damage occurred across the area. A 12 inch diameter tree was split at its base near Ingalls Avenue and Larkin Avenue. Numerous tree limbs up to six inches in diameter were blown down along Larkin Avenue between McDonough Street and Black Road. A two foot diameter tree was blown down. Two trees and numerous tree limbs were blown down near Central Avenue and 103rd Street. Southbound I-55 was impassable between County Line Road and Kingery Highway with water at least a foot deep causing motorists to use the shoulder. A trained spotter in Woodridge measured 3.30 inches of rain. A large tree branch and numerous smaller branches were blown down. Numerous large trees were blown down. Numerous trees were blown down. A large healthy tree limb was blown down. Large tree limbs were blown down. Multiple large trees were blown down. Two to three feet of standing water was present on southbound I-55 between Central Avenue and County Line Road with only the right lane passable. A COOP observer three miles southwest of Midway Airport measured 2.78 inches of rain. La Grange Road was closed between 47th Street and 49th Street due to water over the roads. A home on the 15700 block of Peggy Lane was struck by lightning sparking a fire. The building was not occupied because it had been struck by lightning earlier in the year; however, a worker inside the building was shocked and had to be transported to the hospital. The access road to North Lake Shore Drive from North Michigan was closed due to flooding. There was also flooding at North Avenue under Lake Shore Drive. A tornado caused damage to trees and residences between Plainfield and Romeoville. Over 50 trees, including many large softwood trees, were uprooted within a concentrated path. A dozen modest to large trees were blown to the northwest against the eastward path of the storm. Numerous roads were blocked due to fallen trees. There was minor damage to numerous residences in the Woodlands of the Reserve and Lakewood Falls subdivisions. This damage was mainly siding and shingles peeled off along with windows blown out. The tornado crossed I-55 near mile marker 261. The tornado was embedded within a larger area of straight line wind damage. Maximum winds were estimated to 95 mph. A six inch diameter tree was blown down near Naperville-Plainfield Road and 135th Street. Large tree branches were blown down approximately half a mile west of Central Avenue and 159th street. Tree limbs to around 3 inches in diameter were blown down. A four inch diameter tree was snapped near St Francis Road & Harlem Avenue. A metal fence was also blown down in Frankfort.
