SNOW is on the way late tonight into Monday morning. While the pavement is warm, heavier bursts of snow could produce a little snow accumulation on pavement, bridges, and overpasses. Remember, bridges and overpasses freeze first and we will likely have slick spots on colder elevated surfaces.
4:00 AM Monday: Snow will develop in the mountains. Temperatures in this area will range in the lower 30’s and the snow is expected to be mainly on the light side with a few moderate bursts possible. A few slick spots will be possible, especially on colder surfaces and bridges.
By 7:00 a.m. Monday, light to moderate bursts of snow will be likely along the US Route 460 Corridor and points north into Central Virginia. Snow will initially melt on contact due to warm ground, but the concern is for heavier bursts as the overrunning interacts with a weak low pressure system off the Carolina coast. Along with cold high pressure building in from the north, temperatures will remain around freezing through mid-morning.
After 10:00 a.m. Monday, any snow accumulation on pavement will likely begin to melt. It’s early December and there’s still somewhat of a sun angle, where the heating from the sun can still make it through the clouds and warms the pavement. Snow or rain/snow mix will exit the Lower Mid-Atlantic by early Monday afternoon with some partial clearing.
