Abnormally cold weather will arrive in D.C. area on Black Friday. It may stay awhile.

Consider that all but four days this month have been warmer than normal; we’ve had three days in the 80s, four days in the 70s and 13 days in the 60s, producing an average high of around 66 degrees. Predicted highs starting Saturday will be about 25 degrees lower than this.

The morning lows in the 20s will represent a jarring shift from the 40s that have prevailed in recent weeks. Reagan National Airport has yet to post a temperature lower than 36 this fall, whereas it normally records its first freeze by Nov. 17. Starting Saturday morning, the airport should dip below 32 degrees every day for nearly a week.
