Appomattox and Buckingham counties east of Lynchburg were the snow bullseye on Saturday, with several reports of 5-7 inches in that area from a slow-moving heavy snow band sliding southeastward on the western edge of a much broader area of snow that brought lighter accumulations to much of the Carolinas and southern and eastern Virginia. Overnight, upslope snow bands to the west may add some more white to the ground in locations primarily west of I-77 and near the West Virginia border, with some snow showers farther east in the New River Valley, perhaps even some flakes in the Roanoke Valley. A few heavier bands could bring a white ground farther east. Northwest winds overnight are bringing a punch of Arctic air, with lows in the teens west of Roanoke, and perhaps a few readings even colder than that. Highs will struggle to make freezing in most areas Sunday, but will vault back up into the 40s and even low 50s during the day Monday.
We have two precipitation events to watch in the week as low-pressure systems move east out of the central U.S. and pull moisture northward ahead of them. Each of them — the first arriving late Monday night into Tuesday, the second Thursday night into Friday — may run into some leftover cold air banked against the Appalachians. A brief period of freezing rain, sleet or even snow is possible late Monday or early Tuesday with the first system before most areas change quickly to rain. The late-week system, however, may encounter more blocking features to the north that hold the cold air in more strongly, with a chance for more significant and widespread wintry precipitation. We’ll follow the details as the week develops.
