About 60 miles (90 kilometers) to the south, another fire grew to about 3.9 square miles (10 square kilometers) before its advance was halted in the afternoon.
High winds also knocked out power to more than 260,000 homes and businesses in Texas, Oklahoma, Arkansas, Missouri, Illinois and Indiana, according the website poweroutage.us.
The National Weather Service issued blizzard warnings for parts of far western Minnesota and far eastern South Dakota starting early Saturday. Snow accumulations of 3 to 6 inches (7.6 to 15.2 centimeters) were expected, with up to a foot (30 centimeters) possible.
