PM Update: Frigid through tomorrow
5:45 p.m. update: Wind advisories have been discontinued, but it's still really windy. At 5 p.m., winds were sustained at 25 mph at Dulles Airport with gusts to 41. That made the wind chill 3 degrees.
From 3:35 p.m.Wind advisories remain in effect 'til 10 p.m. this evening, and for good reason. Winds have been howling out of the northwest, sustained as high as 25-30 mph. When you combine that with temperatures only rising to the mid-20s most spots, you've got a recipe for wind chills that have not gotten out of the teens today which drop further when the sun sets.
Through Tonight: Cold!! Mostly clear skies and a still gusty wind only add to the misery. Lows fall to 20 or below across the entire area, ranging from the middle to the upper teens. Wind chills may near 0 at times and won't get much above the single digits. Thankfully, winds do slacken a bit, but we should still see gusts over 20 mph through the night.
Tomorrow (Tuesday): Mostly sunny and still frigid. Highs should reach the upper 20s to near 30. Winds pick up again during the daylight hours, but not as strong as what we witnessed today. Some gusts past 30 mph are likely.
Wind gusts & snow amounts: How 'bout them winds? National's top gust so far today was 36 mph, Dulles has hit 43 mph and Baltimore-Washington reached 39 mph. Some other big(ger) gusts include: 57 mph at Golf Estates, Md. and 49 mph at Sunset Hills, Va. These same winds helped kick up the lake streamer that passed through last night. Reports of .2" at College Park, .3" at Germantown, and .4" at Potomac were pretty representative of places that got into the heart of the band.
