A Winter Weather Advisory is in effect, as of midnight, for Arlington and much of the rest of the D.C. area.
The National Weather Service says 4-6 inches of snow is possible throughout the day today (Saturday) inside the Beltway, but other forecasters say we could see as little as an inch.
Road crews were busy pre-treating local roads and highways Friday in anticipation of the snow, which is expected to begin falling soon.

National Weather Service has increased expected totals to 4-6”…interesting, and I’m happy if we get it…but I’ll go on record and say I’m in the camp of I think it’s too high. I see why they did it (new NAM model right there) but I just think it’s a little high for I-95. pic.twitter.com/GmfxxJROgP
