Most models are now in agreement that we will likely see a period of light to moderate snow showers early Monday morning. This is a “medium” confidence forecast due to a few models bouncing back and forth, however, the majority of the models have trended in an upward direction with wintry precipitation. This WILL NOT be a huge event, but “a taste of winter” to remind you that this is December! Consider this the “appetizer” that you would order at Applebee’s.
Since temperatures will rise into the mid 40’s to low 50’s Sunday afternoon, pavement temperatures will run well above freezing. However, if the snow comes down decent with temperatures just at or below freezing, some secondary roads, bridges, and overpasses could have some slush. Most accumulation will occur on grass and elevated surfaces.
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.
