Upshur County will have four warming stations open tonight as wind chills dip as low as 20 degrees below zero.

The warming stations will be held at Chapel Hill United Methodist Church, Banks District Volunteer Fire Department, Ellamore VFD and Warren District VFD. They will open at 6 p.m. Wednesday evening.

A wind chill advisory issued by the National Weather Service remains in effect until 1 p.m. Thursday.

“Dangerously cold wind chills with snow showers and squalls,” the advisory reads. “Additional snow accumulations of up to one inch. Winds gusting as high as 40 mph. Wind chills as low as 20 below zero.”

The NWS warns West Virginia residents of slippery roads, frostbite and other cold-related dangers.

“Plan on slippery road conditions,” the NWS says. “The hazardous conditions could impact the morning or evening commute. The cold wind chills could cause frostbite on exposed skin in as little as 30 minutes.”

More than 40 counties across West Virginia canceled school Wednesday due to the extreme cold temperatures, including all in the north-central part of the state.
