ANNANDALE, VA – Cold air pooled in the Virginia suburbs before dawn Saturday, with lawns silvered in frost and the air sharp under clear skies. The National Weather Service’s Frost Advisory remains in effect through 9 a.m. for much of Northern Virginia, including Fairfax, Arlington, and Prince William Counties. Residents should protect tender plants, check outdoor faucets, and prepare for another stretch of chilly mornings before mild afternoons return by early week.
According to the National Weather Service in Sterling, calm conditions today will give way to mostly sunny skies with highs near 58°F. Saturday’s frost should fade by midmorning, though shaded spots may stay slick early on. Sunday and Monday stay largely dry, with temperatures hovering around 60°F during the day and slipping into the low 40s at night. A light northeast breeze Sunday and Monday may make the evenings feel crisper, ideal for early Halloween decorating or outdoor cleanup before rain chances return midweek.
Drivers along I-95 and Route 50 can expect clear roads through Monday, but cooler morning commutes will call for heavier jackets and defrosted windshields. Gardeners and pet owners should stay alert again late Sunday night, when temperatures dip close to the frost threshold in sheltered areas.
By Wednesday, a few light showers may develop — a hint of wetter, colder air beginning to organize ahead of Halloween.
A chilly November lies ahead, and this weekend’s frost is only the season’s opening act.
