The chill in the air today was fitting for the season.  Reagan National topped out at 42, which within a degree of exactly “normal.”  Overnight temperatures are also “normal” – dropping into the 20s most spots. Friday’s a decent looking winter day, as the mercury edges modestly above normal levels before a chance of a bit of light snow at night.

Through Tonight: Clear skies early become partly cloudy late at night.  Lows dip into the low 20s in the colder suburbs to the upper 20s to near 30 downtown.  Winds are light out of the south at 5-8 mph.

Tomorrow (Friday): Skies are partly cloudy for much of the day, becoming mostly cloudy towards sunset.  A light wind from the south (near 10 mph) helps temperatures rise about 5 degrees higher than today, into the mid-to-upper 40s.

Full “wolf” moon: The wolf moon was technically 100 percent full at 11:52 p.m. last night, but it’s nearly full this evening.  It got its name due to the gathering of hungry wolves around Indian villages in the mid-winter cold and snows.
