LUBBOCK, Texas — The nation’s midsection again dealt with blizzard conditions Monday, the storm bringing hurricane-force winds to the Texas Panhandle, closing highways, and knocking out power to thousands in Texas and Oklahoma.

Kansas, already under a deep snowpack from last week’s snowstorm, was on high alert as the system headed north and east Monday evening and overnight. The storm is blamed in the death of a 21-year-old man whose SUV hit an icy patch on Interstate 70 in northwestern Kansas and overturned Monday.
