Virginia wakes to gray skies and a cool bite as clouds hang low over Northern Virginia. Damp pavement reflects headlights across Annandale neighborhoods, hinting at a changeable stretch ahead.

This morning starts quiet and cool, with temperatures in the mid-30s across Fairfax County. Winds stay light, but the chill feels sharper before sunshine breaks through later. By afternoon, highs reach the mid-40s, offering brief relief for weekend errands.

Attention turns to Sunday as a developing system tracks closer. Light rain may arrive by late morning, with chances increasing through the afternoon and evening. Roads like I-495, Route 50, and local connectors could turn slick during peak travel hours. Plan extra time if heading out.

The bigger shift arrives Monday. Temperatures surge into the low 60s, unusually mild for late December. Rain chances rise again, adding standing water to roads and parking lots. That warmth won’t last long.

Behind the system, colder air pushes in quickly Monday night. Lows drop into the upper 20s, creating a flash-freeze setup. Any leftover moisture may refreeze, especially on bridges, ramps, and shaded side streets. Early commuters Tuesday should watch for black ice.

By midweek, winter reasserts itself. Sunshine returns Tuesday, but highs stay near the mid-30s. Another cold night follows, reinforcing slick-spot risks during early mornings. New Year’s Eve trends dry and cold, with temperatures near 40 degrees to ring in 2026.

Drivers should stay alert through these rapid changes. Keep coats handy, slow down on wet roads, and watch for refreezing after sunset.
