The National Weather Service issued heavy snow warnings for parts of Oklahoma, Missouri and Kansas late Friday. Some areas could expect up to 9 inches of snow, it said.

But forecasters canceled the warning for central and northeastern Oklahoma early Saturday, as the storm track shifted to the northwest, carrying the worst of the weather into Kansas.

Last weekend's storm coated much of the Plains in ice before dumping snow on the Northeast. It killed at least 38 people, mostly in traffic accidents, including 23 people in Oklahoma alone.

At its height, a million customers in Oklahoma, Kansas and Missouri were blacked out. Crews worked Friday to restore power to 280,000 homes and businesses that were still in the dark, but the latest storm could complicate those efforts.

An Xcel Energy serviceman working in an Oklahoma City neighborhood peppered by toppled trees said Friday he expected the new storm to hamper recovery efforts, but not create massive new power failures.

"All this kind of work is safety-based, so any time you get another weather aspect, then there goes another safety factor," said Scott Falkner, of Clovis, N.M.

Weather Service meteorologist Pete Snyder agreed with that assessment.

"For crews that are out there trying to restore power, it'd be more of a headache," Snyder said.

Bill Weaver, a Tulsa resident who moved here two years ago to escape hurricane-battered New Orleans, waited in his frigid home Friday for the electricity to be turned back on, deadpanning: "So, here we are."

He had two gas-log fireplaces going, warming about a third of his home.

"It doesn't keep the showers warm," Weaver said. "It's cold baths."

Earlier in the week, President Bush declared a disaster emergency in Oklahoma, which freed up resources to respond to the storm. Oklahoma Gov. Brad Henry said Friday that he plans to seek a major disaster declaration, which would provide assistance for individuals and local governments.
