Annandale, Virginia – Northern Virginia begins the day under low gray clouds and a noticeable chill, setting the stage for a stretch of rapidly changing weather that will affect travel and daily routines through the New Year.
Quiet, Cool Start to the Weekend
Saturday morning temperatures hover in the mid-30s across Fairfax County, with damp pavement reflecting early headlights in residential neighborhoods. Winds remain light, but the cool air feels sharper before clouds thin later in the day. Afternoon sunshine allows highs to climb into the mid-40s, offering a brief window of calmer conditions for errands and outdoor plans.
Rain Returns Sunday
Attention turns to Sunday as a developing weather system approaches from the west. Light rain may begin by late morning, with chances increasing through the afternoon and evening. Drivers on major routes such as I-495 and Route 50 should plan for slick roads during peak travel times. While rainfall amounts look modest, wet pavement could slow traffic and increase stopping distances.
Unseasonable Warmth on Monday
The most noticeable change arrives Monday as temperatures surge into the low 60s, unusually mild for late December in Virginia. Additional rain is possible, leading to areas of standing water on roads and in parking lots. This brief warm-up may feel welcome, but it comes with an important caveat.
Cold Air Follows Fast
Behind Monday’s system, colder air rushes in quickly Monday night. Overnight lows fall into the upper 20s, creating a flash-freeze risk. Any lingering moisture from rain could refreeze, especially on bridges, ramps, and shaded side streets. Early commuters Tuesday morning should be alert for black ice, even where roads appear dry.
Midweek: Winter Reasserts Itself
By Tuesday, sunshine returns but temperatures struggle to rise beyond the mid-30s. Another cold night reinforces the risk of slick spots during early morning hours. Conditions trend dry into New Year’s Eve, with highs near 40 degrees, allowing for a cold but calm transition into 2026.
Travel and Safety Tips
Drivers and pedestrians should stay prepared as conditions change quickly. Keep warm layers accessible, slow down on wet roads, and remain cautious after sunset when temperatures drop and refreezing becomes more likely.
