Snow and wintry mix across Far Northern Virginia this morning will come to an end by midday. High pressure will funnel colder air down into the Lower Mid-Atlantic later today as another wave of precipitation develops and moves across the area.
Rain and sleet will change to snow this evening (after 6:00 p.m.) along I-64 south to US Highway 460 and 360. Between US Highway 460 and 58, the precipitation will mix with and changeover to sleet and freezing rain, with light to moderate icing expected. The precipitation will move out of the region by Friday mid-morning.
Snow and sleet accumulations will range from 1 to 2 inches along US Highway 460 to locally 4 inches where the heaviest snow falls overnight — along the Interstate 64 corridor. This swath of snow could move north or south by about 30 miles or so.
More sleet will mix with freezing rain along and south of US Highway 460 to US Highway 58, with ice accumulations around one tenth of an inch. Locally higher amounts up to two tenths are possible where areas see more freezing rain than sleet.
SIGNIFANT ICE STORM POSSIBLE SATURDAY
Models are suggesting an area of low pressure off the Mid-Atlantic coast with cold air trapped at the surface. The air aloft is not cold enough to support snow and most of the precipitation along and Northwest/west of US Route 360 will be in the form of sleet and freezing rain. Ice accumulations one quarter to one half inch is possible, with power outages and tree damage a possibility. We will continue to keep you posted on the latest information over the next few days.
