If you are traveling tonight through the higher terrain areas of northern WV and southwestern PA, be aware that localized instances of freezing drizzle as well as re-freezing snow melt may create slick road conditions. Visit your state's DOT for the latest road conditions through the overnight period.
A weak disturbance crossing the Great Lakes and through the forecast area will provide some a few light snow showers crossing the north on Saturday. Another low pressure system will arrive on Sunday bringing a rain/snow system with most of the snow falling over the northern counties and the higher terrain. The lower elevations will see a change over or mix to rain. Monday will feature clearing conditions through the day with potential morning precip before it clears out.
