More than 100 vehicles smashed into each other or slid off the interstate in Michigan on Monday as snow fueled by the Great Lakes blanketed the state. The massive pileup prompted the Michigan State Police to close both directions of Interstate 196 just southwest of Grand Rapids. The State Police said there were numerous injuries but no deaths had been reported. The crash is just the latest impact of the major winter storm moving across the country. The National Weather Service issued warnings about either extremely cold temperatures or the potential for winter storms across several states.  A day earlier, snow fell as far south as the Florida Panhandle and made it harder for football players to hang onto the ball during playoff games in Massachusetts and Chicago.
