Severe weather hammered parts of Wisconsin Wisconsin overnight. Damage in St. Croix County was being assessed Tuesday, in a part of the state that has been suffering through weeks of dry weather. Jack Colvard is the county director of emergency management, and believes the damage was caused by straight lines winds from thunderstorms which rolled through the area. He says at least 24 barns are damaged or destroyed, with some loss of livestock. St. Croix County is among 52 Wisconsin counties for which Governor Jim Doyle is seeking a federal disaster declaration due to drought conditions.
