The snowstorm that socked western Nebraska and the rain that soaked the east should all be gone by Halloween.

But while Lincoln's ghosts and goblins will have to carry only their traditional candy sacks as they go door to door Saturday night, kids in the west may have to carry shovels.

Forecasters Thursday night said the snowstorm that closed Interstate 80, postponed football playoffs and left drifts up to 3 feet high, particularly in northwest Nebraska, should move out of the state by Friday night, along with the clouds that brought more than an inch of rain to Lincoln on Thursday.

After highs Friday from the upper 30s west to upper 40s east, temperatures should recover to the high 50s Saturday, except 40s where snow still covers the ground. Lincoln could see 63 on Sunday.

Meanwhile, Thursday night, the third storm to cross Nebraska this month was making its way farther east than earlier expected.

A blizzard warning for northeast Colorado and northwest Kansas also included part of southwest Nebraska, where 45 mph winds were forecast to drift another 5 inches of snow overnight.

A winter storm warning, including heavy snow and 35 mph winds, stretched as far east as North Platte. And a winter weather advisory reached as far east as Kearney, where up to 4 inches of wind-blown snow was possible.

Early Thursday evening, the Department of Roads closed I-80 from North Platte west to Wyoming. It had been closed from Big Springs west since Wednesday night.

Storm totals by Thursday night were topped by a foot at Rushville and 10 inches elsewhere in Sheridan County and at Hemingford.

Before pushing into Nebraska, the storm brought blizzard conditions to Colorado and Wyoming, causing treacherous roads, closing schools and canceling hundreds of flights.

Wind-driven snow built to blizzard conditions over much of eastern Colorado on Thursday. The weather service warned most area roads would be impassible Thursday night because of blowing snow and near-zero visibility.

"Big storms like these, they seem to come around every 10 to 12 years," said Kyle Fredin, a National Weather Service meteorologist.

The heaviest snowfall in the Denver area in a decade forced the closure of hundreds of schools and businesses. Roads across the region remained snowpacked and icy.

Denver-based Frontier Airlines said it canceled 44 flights in and out of Denver International Airport. Other flights were delayed by up to four hours. United Airlines, the airport's dominant carrier with about 400 flights per day, canceled half its flights Thursday to prevent delays and cancelations from spilling over into Friday, spokesman Charlie Hobart said.

Airport spokesman Chuck Cannon said crews were using 174 pieces of snow-removal equipment to keep runways and taxiways clear as they dealt with severe wind gusts. Cannon said two departure and two arrival runways were open. The airport received at least 16 inches of snow with 5-foot snow drifts east of Denver, the weather service said.

The Colorado Department of Transportation closed a 140-mile stretch of Interstate 70 from near Denver to Burlington and 55 miles of Interstate 76 from Lochbuie to Fort Morgan. Plows struggled to keep up with the blowing snow, said CDOT spokesman Bob Wilson.
