Highs managed to get a little warmer than forecast today – reaching the low 30s rather than holding in the upper 20s to near 30. But that’s not exactly balmy, and wind chills made it feel like 20 much of the day. Tonight is borderline bitter – especially in the colder suburbs – but temperatures make a run at 40 tomorrow, with slightly less wind than today.
Through Tonight: Mostly clear and to once again state the obvious: cold. It has a decent chance to be the coldest night of the winter so far, with lows in the low-to-mid teens in the colder suburbs and low-to-mid 20s downtown. Reagan National’s coldest temperature this winter so far is 24, and Dulles 16. Both of these could be challenged. Winds are light, from the southwest at around 5 mph.
Tomorrow (Friday): Under mostly skies, temperatures mount a nice recovery. Highs reach the upper 30s to around 40 downtown. Winds are light, from the west around 5-10 mph.
Geminid meteor shower: If you’re hardy enough to brave the cold, pre-dawn skywatchers might spy a few Geminid meteors streaking through the sky (after moonset, which is 3:40 a.m.). The shower actually peaks Friday night, but increasing clouds are likely to be an issue and, before that, the waxing moon (which doesn’t set until 4:38 a.m.) whose light will making spotting meteors somewhat challenging.
