Meteorological synopsis

NEXRAD weather radars composite image of the thunderstorms producing tornadoes in the south-central United States

On May 1, 2008, a large low pressure system developed over Nebraska, with a long warm front stretching east towards the Great Lakes. A cold front and dry line were situated across Oklahoma and Kansas during the late afternoon. The Storm Prediction Center (SPC) issued a moderate risk of severe weather for eastern Kansas and a small part of Missouri, which included Kansas City.[5] On May 2 another moderate risk of severe weather was issued by the SPC from Central Illinois to northern Louisiana.[6] The risk area was later revised southward to only include eastern Arkansas, western Tennessee, and northwestern Mississippi.[7] Most of the severe weather shifted into Arkansas where dewpoints were near 70 °F (21 °C) with CAPE values over 2000 j/kg (in some places up to 3000 j/kg) and helicity values (potential for rotating winds) were exceeding 200 m2/s2.[8]

While most of the severe activity was situated across the southern states, tornado watches were also issued for portions of southern Wisconsin, southern Michigan and northern Indiana as activity developed near the center of the low.[9][10] No tornadoes were reported in this watch area.[4]

On the northern fringes of the storm system heavy snow fell across northeastern Wyoming and western South Dakota. The town of Lead, South Dakota received a total of 54.5 inches, or about 4.5 feet (1.4 m) of snow from April 30 to May 2. Several other areas received one four feet (30 120 cm) of snow.[11]

In the overnight hours of May 2, the supercells re-organized into a squall line/serial derecho that moved across the eastern Great Plains. Significant damage was reported across the Kansas City area, particularly in the Gladstone area near 77th Street and Euclid and northwest of Liberty near 108th Street and Cookingham were several homes and businesses were severely damaged or destroyed, including an Arby's restaurant. Several other commercial structures and homes sustained significant damage and railway cars were also overturned. Forty-thousand Kansas City Power & Light customers were left without power. At least three people were injured by the storms in the Kansas City Metro Area. St. Pius X High School and Oak Hill Day School were closed on Friday as a result of the storm.[14]

It was later confirmed that much of the damage was caused by two strong tornadoes that were embedded inside the derecho; an EF2 in Gladstone and an EF3 in Brookridge. According to Kansas City Mayor Mark Funkhouser, over 300 structures were damaged. In Gladstone over 200 buildings were damaged and several were destroyed according to the mayor. Tornadoes also hit Douglas County, Kansas causing locally significant damage. There no reports of fatalities with these storms. It was later reported that despite tornado warnings, many tornado sirens were not sounded in Douglas County and in other parts of the Kansas City Metro.[15][16][17]
