The weather forecast calls for a dusting of up to two inches, with the accumulation chances greater as you head towards Baltimore. But the real threat here is the temperature drop. The National Weather Service says “unseasonably cold weather will settle into the region Friday and Friday night. Wind chill values may approach zero friday morning.”

So bundle up D.C. and remember: If you see a person in need of shelter, call either 1-800-535-7252 or 202-399-7093 to connect with D.C.’s shelter hotline.
