A widespread derecho impacted the Midwestern United States, mostly the states of Iowa, Illinois, and Indiana, between July 15–16, 2024. Extreme atmospheric instability fueled the development of a powerful bowing mesoscale convective system that caused widespread wind gusts upwards of 75 mph (121 km/h), especially across Illinois, as well as multiple tornadoes that affected the cities of Des Moines and Davenport, Iowa,[1] as well as the Chicago metropolitan area. One fatality has been confirmed from Indiana,[2] with tornadoes killing another in New York.

Meteorological synopsis

Observed sounding at 19z from Davenport, Iowa

The Storm Prediction Center outlined a moderate risk convective outlook at 20z, as extreme atmospheric instability and favorable vertical wind shear was predicted to be favorable to the formation of a bowing mesoscale convective system. Initial estimates stated that widespread wind gusts up to 60–75 mph (97–121 km/h) would be likely, as well as occasional gusts up to 85 mph (137 km/h).[3]

Concerns over the predictability of the incoming system prompted a rare 19z sounding from National Weather Service Quad Cities, Iowa/Illinois, near Davenport, Iowa. The returning sounding indicated extreme atmospheric instability values over 6500 J/kg, as well as a favorable vertical shear profile, indicating atmospheric favorability for a strong quasi-linear convective system, potentially with embedded tornadoes.[4]

Derecho

The derecho left 350,000 customers without power from Iowa to Michigan. Wind gusts reached 105 mph (169 km/h) in Camp Grove, Illinois.[5] At Chicago O'Hare International Airport, gusts reached 75 mph (121 km/h). The derecho also closed portions of Interstate 55 in Illinois. In Indiana, a woman was killed by a tree falling onto their house in Cedar Lake, with gusts up to 71 mph (114 km/h) in Athens.[6] Further east, 102,000 customers lost power in the Northeastern United States.[7]
