A significant amount of snowfall is expected for the district tonight.
Heavy snow is expected to begin this evening as a low-pressure system passes over the region.
Snowfall amounts of 10 to 20 cm are likely before the snow ends Tuesday morning. There is also the potential for a brief period of freezing rain later this evening or overnight.
Be prepared to adjust your driving with changing road conditions as rapidly accumulating snow will make travel difficult. Visibility could be suddenly reduced at times in heavy snow.
