As the chinook ends this afternoon, parts of the Interior will see a stray snow shower along with falling temps and locally slick roads. Snow showers and some blowing snow will impact the West Coast as that occurs, with some minor water over ice a possibility as that low shifts inland. Blowing snow over the arctic coast is coming to an end this morning.
