Four people died during a storm that dumped more than 4 feet of snow around Buffalo and forced motorists in 150 vehicles, including a women's basketball team, to ride it out on a day when temperatures dropped to freezing or below in all 50 states. One person was killed in an automobile accident and three others had heart attacks, including two believed to be shoveling snow at the time, Erie County officials said. The snowstorm stranded cars, trucks and buses on a four-mile section near Buffalo. By late Tuesday night, many — but not all — had been freed. Meteorologists say temperatures in all 50 states fell to freezing or below on Tuesday. They say the low temperatures were more reminiscent of January than November. In New Hampshire and elsewhere, icy roads led to accidents. Lake-effect storms in Michigan produced gale-force winds and as much as 18 inches of snow, and canceled several flights at the Grand Rapids airport. Schools closed in the North Carolina mountains amid blustery winds and ice-coated roads. In Indiana, three firefighters were hurt when a semitrailer hit a fire truck on a snowy highway.
