 Mike Stenefer, WTOP News. Manassas at 77, Metro Center 80, Frederick 80 degrees. Some parts of the area could be down to the 60s overnight. We don't want to overlook that we've just in the past half hour had some more pretty heavy rain and thunderstorms pop up. I want to tell you that from Landover and other parts of Prince George's County right along the Beltway through Greenbelt up into parts of Howard County and Anne Arundel County as well off to the east.
