EF1 tornado in Swift County, Minnesota

A tornado touched down southwest of Camp Lake, where it hit some trees at a farmstead. It then moved across fields, damaging or destroying corn fields. It partially tore the roof off a turkey barn before hitting homes along the east side of Camp Lake. It was here that an observer reported his flag was blowing hard from the northwest as tennis ball size hail hit, then the flag suddenly switched and was blowing from the southeast while the hail continued, then from the southwest when the tornado moved in. One modular home had windows blown in, a porch blown away, and its roof was uplifted to the point where driving rain got into much of the house. The tornado then hit an abandoned farm, rolling a mobile home and destroying several outbuildings before moving into Pope County (see separate entry).

A strong and potent upper level disturbance, combined with a cold front sweeping across the eastern Dakotas, fired a line of severe thunderstorms that moved eastward into western Minnesota toward midnight. This line of storms continued to progress east-northeast across southern and central Minnesota, which produced fast-moving tornadoes, severe measured wind gusts, and hail as large as tennis balls. This line slowly weakened as it moved into far eastern Minnesota, with general, non-severe thunderstorms as the line progressed into west central Wisconsin after 3 am.
