Rain showers will change to snow across Southwest Virginia on Thursday evening, and snow showers will continue to spread across the area overnight, according to the National Weather Service in Morristown.

Elsewhere, up to one inch of snow is expected across valley locations, before tapering off around sunrise Friday morning.
