Much of Oklahoma and parts of Missouri were forecast to get 6 inches of snow from Friday to Sunday, even as utilities worked to restore electricity to more than 164,000 customers who lost it in the last storm.
In eastern Oklahoma, ice snapped hundreds of power poles and transmission lines. More than 57,000 customers statewide remained without power late Thursday, six days after freezing rain began to fall, and more than 1,000 people remained in shelters and many schools remained closed.
In Missouri, particularly in the state's southwest section, more than 108,000 homes and businesses were still without power Thursday, the State Emergency Management Office said.
Europeans labored on Friday to restore services across the continent after hurricane-force winds toppled trees, brought down power lines and damaged buildings, killing at least 47 people and disrupting travel for tens of thousands.
Berlin's new main train station was shut down after a two-ton girder fell from the side of the glass facade onto an outdoor staircase. The station was evacuated after the beam plummeted 40 meters (130 feet) on Thursday night, but there were no injuries and the building was reopened Friday afternoon.
More than 1 million homes had no electricity in the Czech Republic, which was hit by winds of up to 180 kph (112 mph). A million households in Germany suffered blackouts and tens of thousands of homes in Poland and Austria also were hit.
David Jones, a meteorologist with Environment Canada, said the Dec. 11 storm was just one of several severe weather events to strike the West Coast this winter. "This one was on an unusual track," he said. "It moved south to north and ran across the centre of Vancouver Island. . . . It just nailed the coast."
Mr. Jones said the storm "had the intensity closely packed" and seemed to unleash its worst punch right where it came ashore, at Cape Beale and the West Coast Trail.
