Saturday Storm System
Another upper-level disturbance looks like it will track through our region Saturday, developing a low-pressure system just off the coast of the Carolinas. This low will hug the coastline as it moves northeast Saturday and Sunday, and bring moisture into the area that will start out as rain on Saturday morning. As colder air is pulled into Central Virginia, rain may change over to a wet snow or wintry mix Saturday late afternoon. If this does occur, accumulation would be limited by surface temperatures remaining above freezing while the precipitation is falling. In any case, it does look like Saturday will have a cold rain in Central Virginia with temperatures remaining above freezing at the surface. Precipitation is expected to end overnight before temperatures at the surface fall below freezing Sunday morning. Any thin, wet spots on pavement, though, may freeze Sunday morning, such as on your front steps or sidewalks.
