The Late May 2008 tornado outbreak sequence was a series of tornado outbreaks affecting the central plains of the United States since May 22 to May 31 of 2008. A total 239 tornadoes were confirmed, with the most intense activity occurring across the Great Plains. One person was killed when a large wedge tornado struck Windsor, Colorado, and two more deaths were reported in Pratt County, Kansas. One person was also killed near Hugo, Minnesota on May 25 and nine were killed by an EF5 tornado that destroyed most of Parkersburg, Iowa and a small subdivision of New Hartford, Iowa (located near Waterloo, Iowa).〔(【引用サイトリンク】 publisher =National Weather Service )〕 Another death, caused by lightning related to the storms, took place in central Kansas.〔(【引用サイトリンク】 publisher =KSNW )〕 ==Meteorological synopsis== On May 22, a low pressure system developed across the Rocky Mountains, with a warm front stretching across the central Plains and a trough stretching north towards Alberta and eastern British Columbia. A moderate risk had already been issued for portions of northern Kansas on May 21, and was upgraded into a high risk during the afternoon of May 22. It was the first high risk outlook in Kansas since May 5, 2007, one day after an EF5 tornado hit Greensburg, Kansas. Severe thunderstorm and tornado watches extended from eastern Wyoming into northern Kansas early on May 22. Just before noon, a mile-wide (1.6 km) tornado was reported near Greeley, Colorado which is about one hour north of Denver. It moved northwest, an unusual path for tornadoes. It struck the town of Windsor at EF3 strength, causing extensive damage to homes and buildings in town/ One person was killed at the Missile Silo Campground near Greeley. An EF2 tornado struck the city of Laramie, Wyoming causing some damage to roofs of businesses and tossing trucks across Interstate 80. Several other tornadoes occurred in Kansas, and even a few touched down as far west as southern California that afternoon. Numerous tornadoes were reported across northern Kansas, however damage was limited due to the sparsely populated areas it affected. Another intense storm traveled across northern Oklahoma during the evening hours. At least 45 tornadoes were reported across the region on May 22.〔(【引用サイトリンク】 publisher =National Weather Service )〕 On May 23, thunderstorms fired up across much of the same areas, where a moderate risk of severe storms was issued for northern Kansas. Tornado watches stretched from Wyoming into Oklahoma.〔(【引用サイトリンク】 publisher =National Weather Service )〕 Supercells were reported across northern Kansas and Colorado as well as southern Kansas were an intense supercell was traveling near the areas hit by powerful tornadoes on May 4–5, 2007. An EF4 tornado affected areas near Quinter. Greensburg, still in the rebuilding process from the EF5 tornado that destroyed most of the town more than one year prior, narrowly missed getting struck again. Homes and trailers were also reported destroyed in Pratt and Lane Counties. There were 55 tornadoes confirmed in the Dodge City warning area alone and over 80 tornadoes confirmed that day and night, with two deaths reported in Pratt County and at least five people were injured in Kansas alone with the most across Stafford County.〔(【引用サイトリンク】 publisher =MSNBC )〕〔(【引用サイトリンク】 publisher =KAKE-TV )〕〔(【引用サイトリンク】 publisher =National Weather Service )〕 On May 24, a slight risk was issued for much of the Missouri River corridor as well as areas along Interstate 35 from Kansas City to Oklahoma City and later into portions of northern Texas. Tornado watches were issued from Minnesota (at the Canadian border) to Oklahoma with a severe thunderstorm watch in parts of Texas.〔(【引用サイトリンク】 publisher =National Weather Service )〕〔(【引用サイトリンク】 publisher =National Weather Service )〕〔(【引用サイトリンク】 publisher =National Weather Service )〕 One thunderstorm produced several tornadoes across Kingfisher and Garfield Counties south of Enid. Most tornadoes were caught on tape by a helicopter reporter for KWTV-TV in Oklahoma City which was also repeatedly broadcast on CNN. One of the tornadoes captured live on CNN and KWTV destroyed a hog farm. None of the employees who worked at the farm were injured, although a few pigs inside the structures were hurt. However, none of the pigs were found dead.〔(【引用サイトリンク】 publisher =KWTV )〕〔 〕 Tornadoes were also reported across the Dakotas during the evening hours for a total of 13 reports throughout the day.〔(【引用サイトリンク】 publisher =National Weather Service )〕 On May 25, notices for moderate risk of severe weather were issued for northern Kansas, southern Nebraska, eastern Minnesota, northeastern Iowa, and western Wisconsin with a slight risk from Texas to northwestern Ontario. Watches extended along all the corridor and storms developed in four different areas including and northern Texas, northern Kansas, central Minnesota and Iowa and southern Manitoba. One particularly violent tornado touched down and struck the Iowa town of Parkersburg, and the northern side of New Hartford. This long track tornado also destroyed homes near Dunkerton and near the Waterloo Municipal Airport. That tornado killed nine people and was later rated an EF5, the first since the Greensburg, Kansas tornado. According to the SPC Storm Reports, 50 tornadoes have been reported throughout the day. At 4:55 pm, an EF3 tornado touched down in Lino Lakes, a northern suburb of the Minneapolis-St. Paul area. The tornado then moved into Hugo where it caused major damage. Around 50 houses were destroyed and 150 damaged in Creek View Preserve and Water's Edge neighborhoods of Hugo, and 500 homes were damaged in total. A two-year-old child was killed and nine people were seriously injured. A moderate risk of severe weather was issued for central Kansas from the same storm system for May 26 while a large slight risk area was issued by the SPC from Texas to southern Quebec and Ontario,〔(【引用サイトリンク】 publisher =National Weather Service )〕 while Environment Canada issued a slight risk for severe weather for southwestern Ontario. The moderate risk in Kansas was a bust as the severe weather was limited to just a few tornadoes across western Texas and central Kansas.〔(【引用サイトリンク】 publisher =National Weather Service )〕 Meanwhile, only isolated strong thunderstorms across southern and eastern Ontario during the evening hours while very limited activity across the Great Lakes and Ohio Valley regions. However two weak tornadoes were later confirmed north of Sudbury and North Bay. Minimal severe activity was reported on May 27 and May 28.〔(【引用サイトリンク】 publisher =National Weather Service )〕〔(【引用サイトリンク】 publisher =National Weather Service )〕 On May 29, the SPC issued a high risk of severe weather across eastern Nebraska and western Iowa including the Omaha, Nebraska metropolitan, with a moderate risk affecting southern Minnesota, much of central Iowa including Des Moines, northern Kansas and southern South Dakota.〔(【引用サイトリンク】 publisher =National Weather Service )〕 At least 20 tornadoes were reported including three that struck areas in and around the city of Kearney, causing damage at the University of Nebraska campus in Kearney as well as the Buffalo County Fairgrounds, the Kearney Regional Airport, and to businesses and homes.〔(【引用サイトリンク】 publisher =National Weather Service )〕 Part of Interstate 80 near Aurora, Nebraska was closed due to downed power lines from a tornado.〔(【引用サイトリンク】 publisher =KHAS-TV )〕 Another tornado, this one rated EF3, caused major damage in the town of Jewell, Kansas, damaging structures and toppling the town's water tower. Significant damage was also reported in Republic County in Kansas and in Jefferson County in Nebraska.

There were no immediate reports of fatalities directly associated from tornadoes.〔(【引用サイトリンク】 publisher =National Weather Service )〕 For May 30, the SPC issued a moderate risk of severe weather for northern and central Illinois, southeastern Michigan, northern Indiana and northeastern Missouri. Tornadoes were reported near Springfield, Illinois, although the heaviest damage was reported across northwestern Ohio, where some homes were destroyed in Putnam and Seneca Counties as the result of two separate tornadoes, rated EF1 and EF2 respectively. People were reportedly trapped inside damaged structures, although there were no reports of fatalities.〔(【引用サイトリンク】 publisher =National Weather Service )〕〔(【引用サイトリンク】 publisher =National Weather Service )〕 For May 31, a moderate risk was issued for portions of the Middle Atlantic states including portions of the Interstate 95 from Virginia to New York City.
