Post-Thanksgiving travel will be treacherous in parts of the Great Lakes region on Sunday due to several feet of lake-effect snow, while biting cold temperatures sweep across a large swath of the United States.

A relentless lake-effect snowstorm has buried parts of the Great Lakes under feet of snow, leaving vehicles stranded, roads impassable and residents scrambling to dig out.

Parts of the Great Lakes region saw new snow Monday and faced the prospect of even more this week after U.S. travelers battled harsh weather to get home after Thanksgiving, forecasters said.
