MINNEAPOLIS (AP) – A storm packing heavy snow and high winds that wreaked havoc as it whipped through Colorado, Wyoming and Nebraska is marching into the upper Midwest as anxious Thanksgiving travelers brace for a busy, if not perilous, holiday week. The wintry storm that left at least one person dead was expected to push eastward into South Dakota, Iowa, Michigan, Minnesota and Wisconsin on Wednesday, while a “bomb cyclone” weather phenomenon was expected to simultaneously topple trees, knock out power and dump snow as it rolled into California and Oregon. The one-two punch made for a double whammy of early wintry weather that threatened to scramble plans for millions of people nationwide during one of the busiest travel weeks of the year.
