More Snow Around Tonight and Tomorrow Slick Roads are Expected and last updated 2021-05-20 22:28:45-04 Widespread precipitation is expected through early Saturday morning as an upper level storm system over the Pacific Northwest continues to send a bunch of moisture into our area. In Eastern Montana, scattered rain showers are expected from tonight through early Saturday morning. In Central Montana, snow is likely from tonight through Saturday morning. It is also possible that some rain may mix in with this snow at times in central Montana, but right now, it looks like most of the precipitation that falls will be in the form of snow.
