Light Snow and Isolated Squalls, Tonight into Early Wednesday... Rain showers will mix with and change over to a light snow and snow showers this evening and overnight. Snow showers and potentially a few squalls are expected overnight. Minor accumulation of up to one half inch are possible at most locations, except up to 1 inch at elevations above 1,500 feet. Accumulations will generally be limited to grassy and elevated surfaces; however, light slushy accumulations are possible on roadways impacted by the heaviest snow showers and squalls. Liquid water may also freeze on untreated bridges and overpasses late tonight. Those traveling tonight and early Wednesday morning should be prepared for slick spots, especially on bridges, overpasses, and at higher elevations, as well as significant reductions in visibility when encountering any squalls.
