ANNANDALE, Virginia – A soft mist clings to tree lines and car hoods across Fairfax County early Wednesday morning, as calm air and light fog mark the transition toward a stretch of cool, classic fall weather. By sunrise, the haze will lift, revealing blue skies and mild sunshine that will carry through the end of the week.
According to the National Weather Service in Sterling, morning fog near Fort Belvoir and along the Potomac River will clear quickly after sunrise, leaving behind dry air and steady west winds. Temperatures will top out in the low 60s Wednesday, with gusts up to 22 mph briefly stirring fallen leaves across driveways and park trails.
Thursday and Friday bring more sunshine and calm conditions as high pressure anchors over the Mid-Atlantic. Lows will dip into the low 40s each morning—cool enough for a light jacket or early frost on windshield edges in rural areas west of the Beltway. Afternoon highs stay in the low 60s under perfectly clear skies, ideal for outdoor work, school activities, or weekend prep ahead of Halloween events.
By Saturday, conditions remain stable and dry. Temperatures may ease upward slightly into the upper 50s and low 60s, with light winds and no rain expected through Sunday. It’s a comfortable, quiet stretch that embodies the heart of Virginia’s late October—crisp mornings, sunlit afternoons, and calm evenings.
Looking ahead, models hint at a more unsettled pattern developing late next week, possibly bringing the next cool-down and the region’s first true cold snap of the season.
