Power outages in Colorado still affected about 88,000 customers and 77,000 in Texas early on Thursday morning, according to the tracking site poweroutage.us.
Stranded motorists across the region had been reached and helped before midnight, a spokesman for the Colorado State Patrol spokesman said early Thursday. Around 1,100 motorists were reported as stranded on Interstate 25 near Colorado Springs a day earlier.
A state of emergency was still in effect in Colorado as cities and towns dig out from the storm during which gusts of 70 mpg pushed tractor trailers sidewise and left up to two feet of snow in some areas.
The storm was blamed for the death of a Colorado state trooper who was hit by a car sliding on ice on the highway while he attended to a car wreck.
Schools and government offices remained closed Thursday across the region.
"There's still a few headlines left on this storm," said Brian Hurley, a meteorologist with the National Weather Service's Weather Prediction Center in College Park, Maryland.
The storm - previously dubbed a "bomb cyclone" for its quick, late season punch - was still expected to prompt warnings of blizzards and snow before noon in north central Kansas and Nebraska, Hurley said.
Remnants of the snow fall and rain would clear from Denver and the mountain and plains areas by midday, he said.
"By mid-morning the heart of the storm will be western Iowa, headed toward Wisconsin and Michigan, where it will bring about a half-inch of warm rain," Hurley said. Some flood watches and warnings were in place in the midwest as rain will spur accumulated snow to melt, he said.
