CHARLESTON, W.Va. -- The temperature dipped to another record low in Charleston on Thursday morning, and roads could be dangerous again Friday morning, but warmer days are on the way this weekend.
The National Weather Service says the temperature in Charleston dropped to a record 1 degree below zero Thursday morning. The previous record for Jan. 30 was 3 degrees in 1966.
Elkins also broke a record Thursday as the temperature fell to minus-11 degrees. The old record was minus-9 degrees on Jan. 30, 1985.
Temperatures in some cities have fallen this week to their lowest levels in decades. Wheeling broke a record on Wednesday that had stood since the 1950s. The low temperature was minus-5 degrees. The old record was 8 degrees on Jan. 29, 1952.
Parkersburg's low on Wednesday was 11 below zero. The old record was 10 below zero on Jan. 29, 1963.
Emergency officials and meteorologists warned that drivers could face black ice and another hazards Friday morning, as snow and ice that melted on Thursday would re-freeze overnight.
Much, if not all, of that snow and ice should melt for good over the weekend, as temperatures were forecast to reach into the high 50s on Saturday in Charleston.
The frigid temperatures have caused minor problems for overstressed electrical equipment, said Appalachian Power spokesman Phil Moye.
"If you look at the exterior wall and interior wall, there's only a few inches between them," Moye said. "When you're trying to heat you're home to 70 degrees and just a few inches away it's freezing outside, that system's going to be working as hard as it can."
Power company workers have been called to repair blown generators or overworked electrical units this week, Moye said, but there haven't been any widespread outages caused by adverse weather and overworked electrical systems.
About 30 percent of power company customers use electricity to heat their homes and apartments.
"On any given day we might have 10 to 12 places that we have to make repairs," Moye said. "A lot of that, especially last two or three days, is due to a heavy flow of electricity."
Appalachian Power customers in West Virginia, Virginia and Tennessee set an unofficial record for the most electrical demand earlier this month. At 8 a.m. on Jan. 7, the power company saw a peak demand for 8,410 megawatts of electricity. This beat a previous record of 8,308 megawatts of electricity set on Jan. 16, 2009.
