(Updated at 9:55 a.m.) Forecasters tweaked their predictions overnight for what intensity of storm they expect to hit the D.C. region today. While there’s still some uncertainty, it appears the impact will be less than originally anticipated.
The latest forecast from the Capital Weather Gang suggests the area could experience drizzle in the morning, changing to light snow in the afternoon, but with little accumulation. It’s expected that areas south of Arlington will get the heaviest snow, but that could change if the storm suddenly surges north.

Arlington and the rest of the Washington region is now under a Winter Storm Watch.
Forecasters at the National Weather Service say up to five inches of snow is possible tomorrow (Thursday). The snow may be at its heaviest during Thursday’s evening rush hour.
Crews are out today pre-treating roads with a brine solution. They’re focusing on primary (red) and secondary (blue) routes, which can be seen on the county’s online 2012-2013 snow map. Workers will deploy from 4:00 a.m.-4:00 p.m. tomorrow to treat and plow roads as necessary during the storm.
Although areas north and west of D.C. may get around 4 inches of snow, significant accumulation isn’t expected in Arlington. The Capital Weather Gang’s forecast currently calls for a warm up on Saturday afternoon that should change the snow to rain or a wintry mix. However, a snow crew will remain on call through Sunday morning to treat icy roads in case a re-freeze occurs.
The National Weather Service has issued a Wind Advisory for the D.C. area Thursday.
