The National Weather Service issued a Winter Weather Advisory until midnight across all of eastern Oklahoma.
The NWS says freezing rain changed over to sleet early Wednesday and will transition into snow as a cold front pushes across Oklahoma.
News On 6 meteorologist Alan Crone says accumulations will range from 1 to 3 inches of sleet and snow. He said there could be some areas that get higher amounts.
Roads and bridges across eastern Oklahoma are slick because of the freezing rain and sleet.
