Virginia – Windshields bead with moisture this morning as pockets of fog drift across Northern Virginia, softening skylines and dulling headlights during the early commute. The air feels damp rather than cold, but visibility can drop quickly near neighborhoods and secondary roads.
According to the National Weather Service, patchy fog develops early today across Fairfax County, including Annandale and the Fort Belvoir area, before giving way to sunshine. Temperatures climb into the low 50s, helping clear lingering mist by midmorning. Calm winds allow fog to form easily, especially near creeks and wooded areas.
The quieter start does not last long. Clouds increase Friday as milder air pushes north. Rain chances rise by afternoon, with wet pavement spreading across the Capital Beltway and Route 236 corridors. Gusts near 20 mph may accompany showers, adding to slick travel during the evening drive.
By Friday night and Saturday, rain becomes more persistent. Highs reach the mid-60s Saturday, well above normal for January, soaking the ground and creating standing water on low spots and poorly drained roads. Drivers should expect slower travel and reduced visibility during heavier rain.
As the system exits late Saturday night, temperatures fall. Wet roads may cool quickly, raising concerns for patchy slick spots by early Sunday, especially on bridges and shaded areas. While snow is not expected, this is prime flash-freeze season after daytime warmth.
Sunday turns cooler and quieter, offering a break before colder nights settle in early next week. Additional advisories could be issued if rain timing or temperatures shift.
