The second of two cold fronts today is completing its push through the area. The gradual cool down during the day should accelerate now as more cold air is inbound and we head into dark. Other than a brisk breeze, and maybe some mood-setting snow flurries on Tuesday, there isn’t too much to worry about weatherwise when it comes to last-minute Christmas planning.

Through Tonight: Most of the rain is moving away. Additional activity should be light and showery. In fact, many places to the west of I-95 are already done. Showers may persist another few hours around D.C. as well as east, and it’s going to take much of the night to clear out. Lows are mainly in the near 30 to upper 30s range (suburbs to city center). Winds are breezy from the northwest around 10 mph, with higher gusts.

Tomorrow (Christmas Eve): After the recent December heat, heading back into winter chill will feel, well, chilly. Most spots probably snag highs for the day somewhere around midnight tonight, with readings struggling to near 40 or the low 40s while the sun is up tomorrow. Windy, too! We could see sustained as high as 20-25 mph in the afternoon and evening, with gusts past 35 mph possible. That puts wind chills in the 20s much of the day, falling to the teens in the evening. Good news is it’s partly sunny, but we may see some thicker clouds and afternoon flurries in spots.

Two days of rain: After a break for much of yesterday afternoon and evening, rain resumed and laid down a soaking over most of the area last night into today. Since it all began on Sunday, totals are generally in the inch to inch and a half range. Through 4 p.m., these are the numbers: 1.09″ at DCA, 1.31″ at Dulles, and 1.10″ at BWI. Radar estimates, while perhaps a bit underdone, indicate most of the region saw similar rainfall, with a few spots of less or more. The most rain fell further to the southwest, down near Charlottesville.
