NowMostly sunny, breezy. Mainly sunny skies following the passage of a cold front this afternoon have allowed temperatures to get a couple of degrees higher than yesterday; readings are generally 70°-72° at 4pm.
Clouds, enhanced by lake-effect precipitation and upslope motion, have been mostly confined to areas west of the mountains, but in the last hour or so, they have drifted over to a nearly complete overcast here at Afternoon Blog Central in the western half of MoCo. Westerly winds will pump in much cooler air overnight, but the low temperatures will depend on how much those winds die down by morning, and how much of the cloudiness associated with a very strong upper-level low persists.
The coolest temperatures of this spell, as Josh has already indicated, are likely tomorrow night and Saturday night, but the century-plus records of DC proper are not in jeopardy. The record lows for the 13th-15th are: 31° (1906), 32° (1875), and 32° (1874).

Tonight and TomorrowMuch cooler. Under partly cloudy skies and diminishing winds, lows tonight will range from the mid 40s in urban areas to some 30s in the cooler 'burbs. Tomorrow will be mostly sunny with highs in the upper 50s to 60°.
