A prolonged period of freezing drizzle and freezing rain on February 19th and 20th produced a coating of ice on untreated surfaces across western Wisconsin. The precipitation fell with temperatures below freezing as a slow moving area of low pressure moved from the Missouri River Valley toward the Great Lakes. Ice accumulations up to a quarter of an inch were reported by a COOP observer in Osseo (Trempealeau County) and most schools were either closed or delayed on the 20th. In addition, with the rain falling on frozen ground, the runoff caused some flooding along the Grant and Platte Rivers in Grant County.
