On May 1, 2008, a large low pressure system developed across the Central Plains with the center situated over Nebraska and a long warm front stretching 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 including 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 there though.

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 1 to 4 feet (30 to 120 cm) of snow.[11]
