Through tonight: Mainly clear skies persist, and winds diminish. With a chilly air mass in place, that’s a good recipe to see temperatures fall readily at night. Lows range from the mid-30s to lower 40s most spots. Some locations well north and west like Purcellville and Frederick could see temperatures touch freezing.
Western suburbs are right around the final freeze date per recent averages. Dulles has an average final freeze of April 20. In Baltimore, it’s April 9. Freezes into May are not unheard of. Dulles last saw one on May 14, 2013, when it hit 32 on the nose.
