COLUMBIA — The National Weather Service has issued a winter storm warning for mid-Missouri, including Columbia.
The warning goes into effect at midnight Friday* and lasts until 6 a.m. Sunday.
Columbia residents can expect freezing rain to begin falling around 1 a.m. Saturday, said Jon Carney, a meteorologist with the weather service in St. Louis.
The rain is expected to freeze into 0.3 inch of ice on the ground by Saturday evening, Carney said.
Following the freezing rain, Columbia could see 1 to 2 inches of snow beginning Saturday night and continuing through 6 a.m. Sunday, Carney said.
Varied conditions are in store for Missouri, with most of the snow accumulation concentrated on the west side of the state. Kansas City could see up to 6 inches of snow, Carney said. St. Louis, though, is expected to see freezing rain, according to The Associated Press.
The weather system will blanket the Midwest and comes just in time for one of the biggest holiday travel weekends of the year, according Associated Press reports.
The weather service is advising drivers to make sure cars are prepared for potentially hazardous conditions, adjust travel times and stock up on emergency supplies, especially in rural areas.
The Columbia Public Works Department said that it would start covering streets with a liquid salt brine Friday afternoon before the rain and ice began. City crews would begin clearing priority routes at 2 a.m. Saturday.
