Update (2:32 p.m.): The Winter Weather Advisory for the Washington area has been canceled.
Original story (12:51 p.m.): The National Weather Service forecast Thursday morning that Arlington County and the region can expect 1 to 3 inches of snow today, down from the 5 inches or so predicted last night.
The weather service also issued a winter weather advisory in effect from 3 p.m. today through 11 this evening. Snow is expected to first mix with rain, followed by periods of snowfall in the late afternoon and evening.
Temperatures will be in the mid-30s, and roads may be snow covered during rush hour.
The most accumulation is expected south of Washington, according to the weather service.
"Our crews worked yesterday evening to prep some of our snow equipment. But now with the morning forecast calling for less snow, the NWS Watch has been removed and is now just an Advisory. As a result, we are scaling back our response accordingly. We will keep a team available all day and evening, and have a skeleton crew overnight that can address spot areas as necessary," Arlington County Department of Environmental Services spokeswoman Myllisa Kennedy told Patch in an email.
"With temperatures expected to stay above freezing throughout the snowfall period and higher pavement temperatures, most main roads will be wet and maybe a little slushy if we get the possible 1-2 inches of snowfall."
School closures are announced online or via a telephone hotline at 1-866-322-4277. County government closures are announced on the county's Snow & Ice Central page, and you can subscribe for updates through the Arlington Alert system.
Snow removal crews will be out all day and evening, according to the Arlington County Department of Environmental Services which manages snow removal.
