If you’re been outside today, this will hardly come as a surprise: the National Weather Service has placed a wind advisory in effect for the D.C. region for the rest of the day. The advisory warns that wind gusts of up to 50 miles per hour will be rolling through the area until 4 a.m. tomorrow morning. Combine that with the currently below-freezing temperatures, and you’ll get some rather frigid conditions, especially as the sun sets.
