On August 10, 2020, a large and intense line of thunderstorms known as a "derecho" swept across much of the Midwest producing wind damage to an area more than 90,000 square miles. The derecho resulted in $11.5B worth of damage, making it the COSTLIEST known thunderstorm event in modern U.S. history. Peak wind gusts topped 140 mph in Cedar Rapids, Iowa, and at least 26 tornadoes were spawned by the storm. More than 20,000,000 people lived in the damage footprint of the derecho, with at least 1,000,000 customers losing power -- some for more than two weeks. Numerous injuries were counted after the storm, and four people lost their lives.
In the NWS Chicago County Warning Area (CWA), over 160 reports of damaging winds were received and 15 tornadoes were confirmed, including an EF-1 tornado in the Rogers Park neighborhood of Chicago. The derecho stands as one of the most impactful weather events to ever impact the NWS Chicago County Warning Area. Additionally, as of 2021, August 10, 2020 is tied with June 22, 2016 as the single calendar day with the 2nd most tornadoes within the NWS Chicago County Warning Area behind the 6/30/2014 "Double Derecho" event.

Tornadoes are listed in chronological order:
|
Tornado #1: Southwest Rockford, IL EF-0
Summary: A very brief tornado touched down near the intersection of Pierpont Ave and Montague Road and continued northeast into the southwest side of Rockford. The tornado ended near the intersection of Ferguson and Loomis Streets. All damage was to trees along the tornado path. |
|
Tornado #2 - Rockford to Caledonia, IL EF-1
Summary: This tornado was associated with the same supercell thunderstorm that produced an initial brief EF-0 tornado immediately southwest of Rockford, but it has been determined these exist as two separate tracks. This tornado developed as the main line of thunderstorms caught up, and eventually merged with, the parent supercell with this path starting near Guilford Road just north of Rockford College before heading northeast. Significant tree damage, consistent with EF-1 wind speeds, occurred in a localized area immediately east of Rock Valley College west of North Perryville Road. The tornado continued northeast, crossing I-90/39, producing sporadic damage before lifting near Caledonia Road. |
|
Tornado #3 - Kirkland, IL EF-0
Summary: Drone footage shared with NWS Chicago as well as satellite imagery revealed a narrow swath of corn flattened in a convergent pattern. This tornado crossed Buck Road and Pearl Street before lifting in a field east of Myelle Road. |
|
Tornado #4 - Ottawa, IL EF-1
Summary: The tornado started south of Marquette Street west of Michigan Street and progressed eastward. The tornado impacted several businesses ripping off well-anchored roofing material and snapping a power pole at its base. It was here that the max intensity of the tornado was reached with peak winds of around 100 mph. The tornado then continued eastward ripping shingles off roofs of buildings and houses just west of Route 23 and shredding trees. The tornado is believed to have lifted in an inaccessible forested area east of the Fox river. Eye witnesses indicated the tornado may have had multiple vortices with clear rising and rotating motion of debris. |
|
Tornado #5 - Southeast Marengo, IL EF-1
Summary: This EF-1 tornado started on Harmony Road immediately southwest of I-90 near the McHenry/DeKalb County line. Tree damage consistent with winds around 95 mph occurred immediately northeast of I-90. The tornado heavily damaged a single family home near Maple Street before heading northeast and lifting near Coral and Dunham Roads. |
|
Tornado #6 - Northwest Elburn, IL EF-1
Summary: Drone footage shared with NWS Chicago reveals a narrow swath of corn flattened in a convergent pattern. In addition, damage to a barn was noted, with a near complete removal of the gabled roof. This damage is consistent with a tornado with winds of EF-1 intensity. |
|
Tornado #7 - Yorkville to South Plainfield EF-1
|
||||||
|
||||||
|
Summary: The tornado started on the far south side of Yorkville near Walsh Drive where a pergola was destroyed, siding was ripped off a house, and parts of a fence and a tree were thrown over a roadway. Eyewitnesses accounts indicate the debris was lifted and twirled, consistent with a tornado. The tornado then progressed east-southeastward producing damage to trees along State Route 126 toward Schlapp Road. The most significant damage was found east of Schlapp Road along Wheeler road where trees were mangled, a farm building was destroyed with debris deposited in a nearby field, and a large grain bin was bent inward. Wood panels were thrown into the ground leaving scour marks in the grass. Six power poles were snapped along Ridge Road, and a 1000-1500 lb auger was moved about 50 feet. This is where the tornado likely reached peak intensity with winds near 105 mph. The tornado continued southeast into neighborhoods south of Renwick Road producing mainly tree damage, and ended just before I-55. A swath of damaging winds consistent with speeds of 70 to 80 mph continued into Crest Hill based on prolific tree damage. |
||||||
|
Tornado #8 - Wheaton, IL EF-1
Summary: A very brief tornado touched down near the intersection of Seminary Avenue and Scott Street before moving northeast where it knocked a roughly 50 foot steeple around to the north side of the College Church in Wheaton. The tornado then produced minor tree damage before lifting near College Avenue and Howard Street. |
|
Tornado #9 - Lombard/Villa Park, IL EF-1
Summary: The same storm which produced the brief Wheaton tornado produced another region of tornado damage immediately east of I-355 just east of Lilacia Park. This tornado also continued in a northeasterly direction, uprooting trees--some snapped at the trunk--as well as causing some house damage including a few with substantial roof damage. The worst damage occurred near and around the Lombard Common just south of St. Charles Road. Damage eased considerably on the north side of the circulation, with a more gradual drop off in damage to its south. The tornado lifted just northeast of the Jefferson Middle School. |
|
Tornado #10 - Spring Grove, IL to Camp Lake, WI EF-1
Summary: This tornado started in northwest Lake County, continued into Wisconsin and through Camp Lake, and appeared to dissipate over the lake in NWS Milwaukee's area of responsibility. Mainly tree damage occurred with the most significant structural damage occurring in northwestern Lake County. |
|
Tornado #11 - Oak Forest-Midlothian, IL EF-1
Summary: A tornado touched down just east of South Harlem Avenue in Oak Forest, then moved nearly due east along 151st Street producing mainly minor tree and structural damage before lifting near the I-57/I-294 interchange in Midlothian. The worst and most concentrated damage then occurred near Midlothian in the region between Cicero Avenue and Pulaski Road. Several large trees and power poles were snapped near their bases in this region, producing damage consistent with an EF-1 tornado. Damage felled consistently in a convergent pattern towards the track centerline. The tornado damage then began to transition to a region of enhanced straight line winds near the I-57/294 interchange where the damage became increasingly oriented in an easterly direction. Downed utility poles and snapped trees indicate wind speeds were likely near 90 mph, with the most notable damage centered in and around the Harvey area bounded on the north by Sibley Boulevard and the south by 159th Street. This high degree of wind damage persisted east into the Shabbona Woods Forest Preserve before easing towards Calumet City. |
|
Tornado #12 - Park Forest, IL EF-0
Summary: A brief tornado touched down very close to the Cook/Will county line near Shabbona Drive. It tracked northeast where it produced a localized area of tree damage consistent with high-end EF-0 wind speeds. The worst damage was confined to a small area near Marquette and Somonauk Parks, although very little structural damage was noted in this area. The tornado lifted over Schubert's Woods Forest Preserve. Sporadic straight-line wind damage continued east towards State Street east of South Chicago Heights. |
|
Tornado #13 - Rogers Park, IL EF-1
Summary: This tornado initially touched down south of the intersection of Crawford and Touhy Avenues in the suburb of Lincolnwood. It then continued moving just north of due east before moving offshore near the Jarvis and Fargo beaches. The most intense damage, consistent with that of a high-end EF-1 tornado, occurred within approximately one mile of the lakefront, as well as near and within Phillip Rogers Park. |
|
Tornado #14 - Grant Park, IL
Summary: An EF-0 tornado touched down just northwest of Grant Park along N 11000 E Road and traveled southeast through Grant Park. Considerable tree damage was found along the path. The tornado ended near Lake Metonga. |
|
Tornado #15 - Kentland, IN Area
Summary: This brief EF-0 tornado was on the ground for less than 1 minute and produced minor damage to a metal farm building immediately west of State Highway 41. |
The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:
| EF0 Weak 65-85 mph |
EF1 Moderate 86-110 mph |
EF2 Significant 111-135 mph |
EF3 Severe 136-165 mph |
EF4 Extreme 166-200 mph |
EF5 Catastrophic 200+ mph |

Environment
 |
 |
| Aug 10, 9 a.m. 500 mb (~18,000 ft) level, showing a strong short wave and associated 50-70 kt speed maximum moving eastward across the Upper Midwest. This would be a drive force for continued upper support through the thunderstorm complex's lifecycle. | Aug 10, 9 a.m. surface weather map highlighting the very moist air mass ahead of the maturing thunderstorm complex at that time. Note the warm front also slowly moving north. This boundary supported continued low-level warm and moist advection (fuel to the storms), as well as a source for low-level veering profiles near it increasing tornadogenesis potential especially in the toward the IL/WI state line by mid afternoon. |
 |
| NWS Quad Cities weather balloon launch at 12 p.m. on August 10 that sampled a high amount of instability thanks to exceptionally steep mid-level lapse rates and very high equilibrium levels, ample moisture, and undirectional mid-level flow of sufficient amount for long-lived, organized, forward-propagating storms. |
 |
 |
 |
| Aug 10, 11 a.m. deep layer wind shear, with values of 40+ kt sufficient for storm organization, and given the unidirectional mid-level wind profile, this also would help support the development of a forward-propagating storm complex. | Aug 10, 11 a.m. surface-based CAPE (instability), with widespread values over 2,500 J/kg indicating a strongly unstable air mass ahead of the incoming thunderstorm complex. | Aug 10, 11 a.m. precipitable water, with an ample moisture reservoir present for the replenishing of moisture into the thunderstorm complex. |
 |
 |
 |
| Aug 10, 11 a.m. mid-level lapse rates with 8C/km or higher through that layer reflecting the potential for rapidly accelerating updrafts. Combined with sufficient low-level moisture and heating, this indicates explosive convection processes. | Aug 10, 11 a.m. low-level wind shear with values of 20-25 kt (that likely increased further as the complex strengthened) indicating cold pool organization from rain-cooled air. A cold pool allows for stronger storm forward motion and wind momentum given the other ingredients. Also these values are sufficient enough for tornado potential if defined storm inflow areas that can harness low-level turning were to develop. | Aug 10, 11 a.m. MCS maintenance parameter, which provides probabilistic information combining shear profile data, mid-level lapse rates, instability, and mid and upper level wind flow. High probabilities of 90+ percent for ~200 miles ahead of the maturing storm complex are not surprising given the high values of these input parameters. |

| These are basically cross-sections of the derecho's wind profile, namely its rear-inflow jet (RIJ), as the system moved from west-to-east over the area. The RIJ is most mature as the system moves over the Quad Cities, with impressive 100+ mph winds immediately off the surface (some realized at the surface). Notice the unidirectional northwest flow of the low-level jet, ideal for momentum transfer of the strongest winds to the surface that was realized with frequent severe wind gusts persisting a half hour in places! Also interesting to note is the wind profile immediately ahead of the front edge of the derecho's front edge (i.e. the wind shift). For the NWS Chicago profile data, there is more low-level shear (~0-1.5 km) in that immediate pre-storm environment which may explain the tendency for more mesovortices and in turn corridors of enhanced wind damage and tornadoes in our area vs. further west. | ||
 |
| Loop of MRMS regional reflectivity and RAP 0-2 km shear (shaded, barbs, and contours), showing the rapid increase in low-level shear as the derecho moved into northern Illinois. The increase in shear is thought to have influenced the development of mesovortices and efficient tornado production in northern Illinois and northwestern Indiana. |
