Centreville, Virginia, sits on the rolling Piedmont west of Washington, D.C. Its inland position limits direct ocean influence, but moist air from the Atlantic and Gulf still reaches the area. Nearby hills and valleys can slightly redirect winds and shape local rain.
Passing low-pressure systems often bring clouds, rain, and shifting winds, especially with cold fronts in spring and fall. High pressure more often brings brighter, calmer stretches, though summer high pressure can hold in heat and humidity. Winter storms may arrive as coastal low-pressure systems move north.
Spring warms unevenly, with changeable days and frequent showers. Summers are long, hot, and humid, with thunderstorms often forming on warm afternoons. Fall usually turns cooler and less humid, though rain can return with passing fronts. Winters are chilly, and snow varies from light coatings to occasional larger storms.
