 Late-day storms for the 4th of July, highs low to mid-90s. Mike Stenifer, WTOP News. Those showers moving through, and thunderstorms, I should say, moving through northern St. Mary's County, another batch cropping up in Stafford County, Virginia, near Garrisonville. It is 80 at Fort Belvoir, 81 in Silver Spring, 83 at Foggy Bottom at 1040.
