Utah Wyoming Derecho 1994 May 31, 1994 One of the few established "Low Dewpoint" Derecho events according to the National Weather Service. What started as a cluster of thunderstorms in southern Nevada rapidly intensified as they moved northeast into west central Utah. Eventually a powerful line of storms formed producing destructive winds across northern Utah, southwestern Wyoming, and small portions of southeastern Idaho and northwestern Colorado. The system was unique as surface dewpoints across the impacted region were in the 40s and low 50s, much lower than the typical high 60s and low 70s dewpoints seen during derecho events in the eastern US.[9]
Heat wave of 1995 derecho series July 11–15, 1995 Affected 15 U.S. states from Montana to New England, as well as Ontario, Canada. Minnesota was hit three times in three days.

Mississippi - Tennessee Valley Derecho of 2004 July 13, 2004 A derecho formed out of the cell that caused the Roanoke tornado. It swept southeast over southwest Indiana bringing winds of around 58 mph to Evansville and much of the city was left without power.[14] As it moved over Kentucky and Tennessee it expanded in size bringing damage to over half of both states with winds peaked at 84 mph in Southern Kentucky. Louisville reported the most power outages since the 1974 Super Outbreak. 60 mph winds were also reported in Lexington and a 70 mph wind gust was reported in Elizabethtown. Hundreds of trees were reported down in Nashville with multiple reports of 60 mph wind gusts.[15]
2005 Upper Midwest Derecho July 23, 2005 A derecho formed in Northeastern South Dakota near Roslyn and traveled through Central Minnesota into West Central Wisconsin, and Central Wisconsin into Southern Wisconsin. The Derecho traveled more than 350 miles (560 km) and produced winds up to 85 mph (137 km/h) with hail up to Half Dollar Size.[16]

October 2010 North American storm complex October 23–28, 2010
April 2011 Serial Derecho and Tornado Outbreak April 4–5, 2011 An extensive serial derecho moved through the entire southeast. The first line formed in Texas and swept northeastward through Arkansas and Northern Louisiana and continued through Kentucky, Tennessee and Northern Mississippi extending over 200 miles in length. As it continued east a new line (associated with the same system) formed over Louisiana and organized over Mississippi and Alabama. At one point the two lines stretched over 800 miles in length. The first line weakened over the Appalachian Mountains while the second one continued across Georgia and South Carolina and grew to also affect Virginia and North Carolina before moving offshore. 1096 wind reports came in, the most on record. 46 tornadoes also touched down.[22][23]
April 2011 Ozarks Serial Derecho and Tornado Outbreak April 19–20, 2011 A second large serial derecho affected areas of the Tennessee River Valley and Midwest. Wind gusts up to 95 mph were recorded. Large hail and 80 tornadoes also occurred with this event. This event would be overshadowed by major tornado outbreaks that occurred just before and after it.[24]
July 2011 Upper Midwest-Great Lakes Derecho July 10–11, 2011 A series of derecho-producing convective systems produced a relatively narrow but lengthy swath of wind damage that extended all the way from the central High Plains to the Mid-Atlantic states on July 10–11, 2011.[25] A small powerful derecho first formed in Southern North Dakota producing winds up to 95 mph (153 km/h), hail up to hen egg sized and nine tornadoes including a large EF2 tornado SE of Napoleon which heavily damaged three farm houses. Two large grain bins were destroyed and thrown considerable distances. Many trees were uprooted or snapped.[26][circular reference] The derecho produced widespread wind gusts and wind damage reports from Southern North Dakota, Central Minnesota and Western Central Wisconsin. The derecho weakened considerably when the July 2011 Iowa-Illinois-Michigan-Ohio derecho sucked the instability and moisture from the storm over Lake Michigan. The derecho traveled more than 400 miles (640 km) and produced nine tornadoes in North Dakota and Western Minnesota.
July 2011 Iowa-Illinois-Michigan-Ohio derecho July 11, 2011 [27]
June 2012 Lower Mississippi Valley derecho June 11, 2012 [28]
Summer of 2012 derecho series June 29, 2012-August 2012 Event on July 26 was the third derecho in 4 weeks to impact west-central Ohio
June 2012 North American derecho June 29–30, 2012 aka "Ring of Fire Derecho", passed through nine states from Indiana to New Jersey, cutting power to millions[29]
June 12–13, 2013 derecho series June 12–13, 2013 Two derechos developed; one on June 12 and another on June 13.
Late June 2013 Chicago derecho June 24, 2013 One person was killed by EF1 tornado near Muscatine, Iowa.[30] Four other tornadoes were also confirmed during this event.
Late June 2014 Derechos June 30-July 1, 2014 Also known as the "'One-Two Punch' Derechos," The first derecho began consolidating over Nebraska and swept eastward over Central Iowa where it organized into a small line of storms bringing winds up to 90 mph in the state. It weakened as it crossed into Illinois with the bulk of the 60-70 mph winds occurring in Wisconsin, though the line did restrengthen over Chicago. A second derecho formed right behind the first one and again brought damaging winds across Northern Illinois. It hit Chicago just 3 hours after the first one bringing 80 mph winds. It continued into Northern Indiana bringing 100 mph winds to Lake County before it began to weaken. It dissipated over Ohio at 4am EDT. 2 people were killed in the second derecho.[31][32]
June 21–22, 2015 Severe Weather Event June 21–22, 2015 Winds of 122 mph (196 km/h) recorded on personal weather station near Hayes, South Dakota before it was destroyed.[33]
2015 Midwest Derecho July 12–13, 2015 A powerful derecho first formed in a cluster in Todd and Douglas Counties in Minnesota and then spread to the east and southeast. A barn was one of the first victims south of Aldrich in Todd County. Next there were reports of trees down in Douglas County. There was also tree damage in Pope and Stearns Counties. Some of the most extensive damage occurred in the Brainerd and Baxter area of Crow Wing County where a National Weather Service survey showed winds in excess of 100 mph (160 km/h) did extensive damage to large, healthy trees, homes, power lines and businesses. Many trees and power lines were down the Baxter area, blocking roads including Highway 371. Two camper trailers were flipped and the Brainerd International Raceway grandstand was damaged. The Gull Lake Dam Campsite was evacuated of campers and then closed with hundreds of trees down in and around the campground. There was also extensive damage on Pelican Lake in Crow Wing County with many trees down and structural damage to resorts and cabins. As the storms sagged south into the Twin Cities Metro Area, heavy rain and lightning were the biggest impacts with 1–2 inches (2.5–5.1 cm) of rain common. 1.7 inches (4.3 cm) of rain fell in an hour at the U of M St. Paul Campus Climate Observatory. A location near Woodbury in Washington County saw 2.41 inches (6.1 cm) of rain. The highest 24-hour rainfall total found so far was 3.25 inches (8.3 cm) near Fergus Falls in Otter Tail County. Lighting sparked house fires in several locations around the Twin Cities.[34] Severe storms merged in west central and central Minnesota and then developed more into a line of storms and produced periodic downed trees, power lines, and occasional estimated winds of 60–70 mph (97–113 km/h) as the storms moved southeast along Interstate 94 and into the Twin Cities metro area. Damage was not as widespread after it moved out of central Minnesota and into east central Minnesota, due to less wind shear and instability.[35] The storms re-intensified as they moved into Wisconsin and continued to move southeast. By late afternoon on the 13th the line of storms were progressing through eastern Kentucky. The derecho traveled more than 900 miles (1,400 km) with winds gusting up to 104 mph (167 km/h).[34]
August 2015 Northwest Michigan Derecho August 2, 2015 Derecho over northwestern Lower Michigan, causing damage to trees at the Sleeping Bear Dunes National Lakeshore and cutting off power to many residents of Traverse City; also impacting the penultimate night of the Traverse City Film Festival, winds of 100 mph (160 km/h) occurred around Sleeping Bear Dunes and Glen Arbor, the largest hailstone in Northern Michigan occurred near West Branch, measured at 4.25 inches (10.8 cm).[36][37]
June 2016 Ohio Valley Derecho June 22–23, 2016 A powerful derecho produced just over 120 reports of either high thunderstorm winds or wind damage were reported to NOAA's Storm Prediction Center from midday Wednesday through early Thursday morning from northern Illinois to Virginia, including a 100 mph (160 km/h) wind gust apparently measured northwest of Battle Ground, Indiana. The temporal and spatial distribution of those wind reports qualified the event as a low-end derecho, according to the criteria used in a 2005 study.[38]
2016 Upper Midwest Derecho July 20–21, 2016 A massive intense derecho formed in central North Dakota during the afternoon of July 20 and moved into northwest Minnesota at dusk. A wind gust of 83 mph (134 km/h) was clocked at the Hallock Airport in Kittson County at 9:34 pm. The storms continued to move to the east and southeast causing damage as they went, including flipping over planes at the Bemidji Airport and peeling off roofs on steel-clad buildings in town. At 1 am on July 21 the storms reached Park Rapids in Hubbard County and downed trees. A wind gust was measured at 55 mph (89 km/h) at the Park Rapids Airport. By 3 am the storms moved into the Duluth area, where the ground was saturated from previous storms, making it even easier for the strong winds to topple large trees. Widespread power outages resulted, and at least 75,000 Minnesota Power customers lost service. The storms also moved through the Boundary Waters Canoe Area Wilderness, tragically killing two campers on Basswood Lake in Quetico, just across the Minnesota border in Ontario. The southern edge of the storms also moved through Central Minnesota and the Twin Cities metro area between 3:30 and 5:00 am, with gusty winds up to 70 mph (110 km/h) out ahead of the storms waking people out of bed and causing minor tree damage along with spotty power outages.[39] Winds were measured at 100 mph (160 km/h) in downtown Duluth and measured at 103 mph (166 km/h) in the ship canal by a 700-foot (210 m) freighter.[40]
May 2017 United States Derecho May 26–28, 2017 Three derechos in a row struck the Ozarks, Ohio, and Tennessee valleys
June 2017 Northern Plains Derecho June 11, 2017 During the morning hours of June 11, 2017, a dangerous derecho tracked eastward out of South Dakota, across Southern and Central Minnesota, and through Northern Wisconsin into the Upper Peninsula of Michigan. The derecho produced widespread wind gusts, large hail, and a tornado. Winds gusts up to 80 mph (130 km/h) were reported in Meeker County, Minnesota with hail up to hen egg size.[41]
July 2017 Midwestern derecho July 19–21, 2017 [42][43][44][45][46]
2018 Mid-Atlantic Derecho May 14, 2018 A derecho traveled over 400 miles (640 km) from Columbus, Ohio to the east coast of Virginia, causing severe thunderstorms, flash flooding, and hailstones the size of ping pong balls.[47]
2018 Northeast Derecho May 15, 2018 A derecho originating in West Virginia traveled over 450 miles (720 km), terminating on the East Coast. This storm system caused damage from as far north as New York and Connecticut, to as far south as Maryland, killing five people and causing extensive damage.[48] Ahead of the derecho, several supercells formed in, and travelled through the Northeastern Tri State Area, as well as Southern New England, producing hail up to the size of baseballs as well as damaging tornadoes.[49] The derecho was notable for several reasons, as it was the first to hit the New York metropolitan area in several years, and it dropped large, life-threatening hail in areas that normally don't see hail at all.
2018 Southeastern Derecho June 28, 2018 Formed in central Tennessee, traveled through the entire state of Alabama to the Gulf coast. One person was killed in Clay County, Alabama by a falling tree. Widespread power outages were reported all across Alabama.[50]
2018 Northern Plains Derecho June 28, 2018 Supercells formed in eastern Montana, producing several tornadoes before rapidly congealing into a derecho producing squall line. The derecho produced widespread wind damage across North Dakota and Western Minnesota. Winds up to 96 mph (154 km/h) were reported with this storm. A man was killed by a fallen tree.[51][52]
2018 Midwest-Mississippi River Derecho June 28, 2018 A derecho producing squall line formed in Eastern Nebraska. The complex of storms moved east across Iowa before turning southeast and moving south along the Mississippi River. Along its path it produced wind damage with gusts up to 85 mph (137 km/h).[51][52]
Table Rock Lake Derecho July 19, 2018 A derecho producing squall line formed in Kansas moving east then turning southeast into Missouri. Many wind gusts in excess of 75 mph (121 km/h) were reported in Kansas. As the derecho went through Missouri, it created dangerous marine conditions in Table Rock Lake. A duck boat capsized in the lake partly due to these conditions killing 17 of the 31 people on board.[51][52]
July 2019 Heatwave Upper Midwest Derecho July 19–20, 2019 A powerful derecho storm moved through the Upper Midwest on the Friday night of July 19, gathering up 73 damaging wind reports, according to the National Weather Service, and the same area remained under threat of more severe weather Saturday, July 20 for northern Iowa, southern Minnesota, Wisconsin and Michigan. Its believed that this storm dissipated before it reached the eastern Great Lakes Region including southern Ontario in Canada and the northeastern United States around July 21. Friday's event resulted in only the sixth known watch (Tornado or Severe Thunderstorm) with Wind Gust potential of up to 105 mph (169 km/h).[53][54][55][56][57][58][51][52]
2020 Southern Plains-Ozarks Serial Derecho April 28–29, 2020 A derecho brought damaging winds to parts of the central U.S. Tuesday night. Near Jasper, Missouri, a semi truck was overturned on Interstate 49 early Tuesday evening because of damaging thunderstorm winds from this squall line. A 75 mph (121 km/h) wind gust was estimated in the area of the incident. Tulsa, Oklahoma, reported estimated wind gusts of 65–75 mph (105–121 km/h) when the squall line of thunderstorms impacted that area early Tuesday evening. A wind gust to 64 mph (103 km/h) was clocked at Springfield–Branson National Airport in southwestern Missouri early Tuesday evening. Some 70 miles (110 km) to the west in Joplin, Missouri, and its suburbs, there were reports of trees and power lines down. The storms also produced hail up to the size of tennis balls – 2.5 inches (6.4 cm) in diameter – near Marshall, Mustang, Ninnekah and Yukon, Oklahoma. This storm system produced more than 450 reports of severe weather in the 24 hours ending early Wednesday morning from Illinois, Missouri and southeastern Kansas to parts of Texas and Louisiana. Most of those reports were for wind damage, strong thunderstorm winds or large hail.[59] The derecho traveled more than 500 miles (800 km) before moving off the coast of Texas and Louisiana into the Gulf of Mexico and produced winds up to 78 mph (126 km/h) with hail up to 3.75 inches (9.5 cm) in diameter and a few tornadoes including a short-lived EF2 tornado north of Hochatown, Oklahoma that tossed two barges over 100 yd (91 m), a home's roof deck was collapsed, and a single-wide manufactured home was destroyed, with its base frame twisted and tossed 100 yd (91 m) to the east. A second house suffered significant roof and structural damage after large gas tanks were tossed into it. A third house had roofing material removed. Numerous trees were snapped or uprooted.[60][circular reference]
Kansas-Tennessee Progressive Derecho May 3, 2020 Second derecho in a week, originating from the same spot. Hit Nashville, Tennessee just 2 months after a tornado devastated part of the city. 130,000 people lost power, making it the largest power outage in the cities history. It was said to be the worst derecho in 16 years.[61]
June 2020 Pennsylvania–New Jersey derecho June 3, 2020 Three deaths were reported in Montgomery County, Pennsylvania and a 93 mph (150 km/h) wind gust was recorded in Beach Haven, New Jersey. 700,000 were left without power.
June 2020 Rocky Mountains-Northern Plains Derecho June 6–7, 2020 This derecho originated over eastern Utah and western Colorado in the late morning of June 6 and crossed the Rockies on to the High Plains before falling below severe limits in eastern North Dakota. A 110 mph (180 km/h) wind gust was recorded at the Winter Park Ski Resort in Colorado. Tree damage was reported throughout metro Denver and wind gusts were clocked at over 75 mph (121 km/h) at several locations in Jefferson, Adams, Douglas, and Denver Counties. Winds in excess of 75 mph (121 km/h) were also recorded in portions of Wyoming, South Dakota, and Nebraska. This derecho was unusual for its origin west of the Continental Divide and the extreme forward speed in its early stages, reaching 120 mph (190 km/h) at some points in western Colorado.[62]
Great Lakes serial derecho of June 2020 June 10, 2020 A widespread thunderstorm wind event known as a squall line formed from a slowly progressing cold front, that was possibly associated with the remnants of Tropical Storm Cristobal. The squall line, later classified as a derecho, blasted the eastern Midwestern United States and Eastern Canada. A rare moderate risk of severe weather was issued for a large part of Michigan and parts of Ohio and Indiana; these regions had not had a moderate risk of severe weather since 2013. With a 5% chance for a tornado 45% hatched chance for damaging winds and 15% chance for damaging hail. Roughly 300 reports of high winds or wind damage were received from Michigan to western New York leaving 700,000 people without power. The storm system produced 7 tornadoes in Ontario.
August 2020 Midwest derecho August 10–11, 2020 aka "Heartland Derecho", A severe weather event which took place from August 10–11, 2020 across the Midwestern United States and portions of southwestern Ontario. The derecho caused notably high wind speeds of up to 126 mph (203 km/h) recorded in Iowa, with post-damage assessments of up to 140 mph (230 km/h) in some places. The derecho also spawned an outbreak of weak tornadoes, and resulted in an estimated $11 billion of damage. In addition, certain areas reported torrential rain and large hail.[63]
October 2020 Northeast Serial Derecho October 7, 2020 This serial derecho on Wednesday, October 7, 2020, caused a 320-mile (510 km) wide damage path in Ontario, New York, Massachusetts, and Connecticut. It formed over Ontario in the morning and raced eastward in New York State in the late afternoon and early evening, gathering strength as it moved across New York and southern New England. Isolated areas received gusts up to 75 mph (121 km/h), causing hundreds of thousands of people to have power outages, as well as tree and power line damage. Microbursts occurred in Root, Pittstown, and Johnsonville, New York, with estimated maximum wind speeds of 80, 90, and 100 mph (130, 140, and 160 km/h), respectively. An EF0 tornado touched down in Canajoharie, New York. An isolated brief EF0 tornado also touched down in Millis, Massachusetts with winds of 75–80 mph (121–129 km/h), only damaging trees and taking down a metal lamp post.[64][65]
December 2021 Midwest derecho and tornado outbreak December 15, 2021 A rare high end serial derecho event struck areas of the Midwest, including Kansas, Nebraska, Iowa, Wisconsin, and Minnesota. Lincoln Airport in Lincoln, Nebraska, with peak winds measured >93 mph (150 km/h). Several power outages were also reported, 200,000 of which were in the state of Kansas. This derecho also produced 120 tornadoes, including 33 rated EF2, making this the largest tornado outbreak ever recorded in December just days after another large outbreak set the record. This also was 4th most tornadoes ever recorded in a 24-hour period in the United States. The same system also produced intense non-thunderstorm winds on the back side of it, which spurred the formation of rapidly-moving fires across Colorado and western Kansas, with attendant dust and debris spreading eastward as well as heavy rain and snowfall to the Western United States.
May 2022 Midwest derecho May 12, 2022 Large amounts of atmospheric instability contributed to a fast-moving and deadly derecho that traveled over 500 miles (800 km) across Kansas, Nebraska, Iowa, South Dakota, and Minnesota with wind gusts up to 107 mph (172 km/h).[66] A powerful serial derecho first started in Central Nebraska, before moving rapidly into South Dakota, where most of the damage occurred, two deaths occurred in Minnehaha County, both were in their cars and were hit by flying debris. Many towns in South Dakota saw significant damage, some of the hardest hit being Salem and Madison. In Marion, several rail cars were tipped over by the extreme winds. In the aftermath, the governor of South Dakota deployed the National Guard in the hardest hit towns to assist with cleanup efforts. A person was injured in a truck rollover in Holt County, Nebraska. In Blomkest, Minnesota, a man was killed when a grain bin collapsed onto his car. Several farms in Western Minnesota and Eastern South Dakota had outbuildings, equipment, silos, grain bins, and barns damaged or destroyed. A moderate risk was issued with a 45% significant severe wind probability at 7:53 AM CST.[67]
May 2022 Canadian derecho May 21, 2022 A fast-moving, intense derecho[68] formed in the morning hours near Sarnia, Ontario, progressing through the London, Toronto, Ottawa, Montreal, and Quebec City metropolitan areas, killing at least ten people[69] and causing extensive damage and power outages affecting an estimated 480,000 people. Wind gusts of over 75 mph (120 km/h) were reported in Windsor, as well as at the Ottawa and Toronto international airports. Kitchener/Waterloo Airport recorded a peak wind gust of 82 mph (132 km/h).[70][71][72] Post storm damage investigation analysis identifies maximum wind speeds reaching 120 mph (190 km/h) in a 3.1 mi (5 km) corridor in Ottawa.[73]
June 2022 Great Lakes derecho June 13–14, 2022 Multiple mesoscale convective systems, with one classified as a derecho thus far by the National Weather Service in Northern Indiana, caused widespread damage and power outages across the Midwestern United States. Damage was particularly intense around the Fort Wayne, Indiana area and portions of northwest Ohio. Another possible derecho caused the worst power outages in the Cincinnati metropolitan area since the June 29, 2012 event. The derecho produced four tornadoes in Ohio and one tornado in Illinois.[74][75]
July 2022 Midwest derecho July 5, 2022 The storms went through the upper midwest, causing massive amounts of wind damage for the thousands of people in the area. This makes the 4th derecho in 7 months to hit the area, when the area typically only gets one every two years. The storms were very high in precipitation, which made the sky appear as a bright green color. The derecho produced two tornadoes in Iowa.[76]
