    DC: Clouds to Move in This Weekend; Warmth to Return Next Week

    Except for the beaches and mountains, rain will avoid much of the Washington, D.C., area through Sunday.

    A wedge of dry air along the I-95 corridor from New England to northern Virginia will fight to keep rain away.

    The cool air that expanded from the Midwest will stick around through Sunday.

    Despite some cloud cover and lower-than-average temperatures for July, the weather will be ideal for most outdoor activities ranging from jogging, swimming and Nationals baseball to construction, yard work and painting projects.

    However, for people heading to the beach, a weak tropical system over the Atlantic could bring rain for a time this weekend. Spotty, drenching thunderstorms will also drift northward over the mountains.

    Temperatures at night into the weekend will dip into the lower 60s in some of the northern and western suburbs but will stop near 70 F in urban areas and at the beach.

    The risk of thunderstorm activity will increase in the I-95 corridor next week as temperature and humidity levels trend upward. Depending on the amount of sunshine, 90-degree temperatures could return for a few days.
