County and VDOT crews are already pretreating roads ahead of the potentially snowy and slippery weather.
WINTER WEATHER ADVISORY IN EFFECT FROM MIDNIGHT TONIGHT TO 6 PM EST SATURDAY… THE NATIONAL WEATHER SERVICE IN BALTIMORE MD/WASHINGTON HAS ISSUED A WINTER WEATHER ADVISORY FOR SNOW… SLEET AND FREEZING RAIN… WHICH IS IN EFFECT FROM MIDNIGHT TONIGHT TO 6 PM EST SATURDAY. * PRECIPITATION TYPE… SNOW… SLEET… AND FREEZING RAIN. * ACCUMULATIONS… SNOW ACCUMULATION OF UP TO 1 INCH… ALONG WITH AROUND A TRACE OF ICE. * TIMING… LATE TONIGHT THROUGH SATURDAY. * IMPACTS… ICY PATCHES ON ROADS AND BRIDGES WILL MAKE TRAVEL DIFFICULT. * WINDS… EAST 5 MPH OR LESS. * TEMPERATURES… IN THE LOWER 30S. PRECAUTIONARY/PREPAREDNESS ACTIONS… A WINTER WEATHER ADVISORY MEANS THAT PERIODS OF SNOW… SLEET… AND FREEZING RAIN WILL CAUSE TRAVEL DIFFICULTIES. BE PREPARED FOR SLIPPERY ROADS AND LIMITED VISIBILITIES… AND USE CAUTION WHILE DRIVING.
(Update at 2:15 p.m.) Arlington County is preparing for the possibility of snow, sleet and freezing rain on Saturday, though the exact forecast is still far from certain.
“Crews began pretreating roads yesterday and will continue today to prepare for the expected icy weather conditions on the roadways,” Arlington Dept. of Environmental Services spokeswoman Katie O’Brien told ARLnow.com Friday morning.
“Due to the low confidence of this forecast, we are still analyzing the level of response that will be required” on Saturday, O’Brien continued. “A determination of resource levels and time of activation will be made this afternoon.”
VDOT, meanwhile, is encouraging drivers to stay off the roads in Northern Virginia on Saturday.
Virginia Department of Transportation and contract crews are preparing for plummeting temperatures and a gamut of winter weather forecast for northern Virginia this weekend, from early Saturday morning through Sunday morning.
Drivers are asked to monitor weather reports for the latest updates to avoid being on the road during periods of limited visibility or icy conditions. Stay off roads Saturday or delay trips until Sunday if possible, to avoid being caught in deteriorating conditions as weather transitions between snow, sleet and freezing rain through the day.
Crews began pretreating roads yesterday and will be staged roadside in the region by 10 p.m. tonight. Throughout Fairfax, Loudoun, Prince William and Arlington* counties (*Arlington maintains own secondary roads) crews treat about 5,200 lane miles of interstates and other high-volume roads with liquid magnesium chloride or brine when conditions allow for winter weather. Learn more about northern Virginia’s snow preparations.
Why does VDOT ask drivers to stay home?
- Visibility will be limited during periods of snow.
- Freezing rain causes an ice glaze that is difficult to see. Black ice often looks like pavement that is simply wet, making it extremely hazardous for driving or walking.
- Four-wheel drive vehicles cannot stop any better than two-wheel drive vehicles on ice.
It could be deja vu if the weather does trend toward more freezing rain. Icy weather caused a number of crashes and other problems on the roads in Arlington less than a month ago, on Saturday, Dec. 17.
All the salt spread on local roads and sidewalks for Thursday night’s snow non-event may come in handy after all.
The National Weather Service has included Arlington in a Winter Weather Advisory. Up to three inches of snow are expected to fall Saturday morning.
From the NWS:

Arlington County brine trucks could be seen pretreating roads around Clarendon earlier this afternoon. VDOT, meanwhile, says it’s preparing for a potentially messy Thursday evening and Friday morning commute.
“Road crews are conducting anti-icing activities today and tomorrow,” VDOT said in a press release. “Please watch for crews as they stage along roads prior to the storm. Crews will treat roads with salt and sand as needed once the storm begins Thursday afternoon, plow in areas where and if snow totals reach two inches, and will remain on duty throughout the course of the storm.”
The snow is not expected to amount to much — maybe just a dusting to an inch. But even a small amount of snow could cause slippery conditions and virtual gridlock.
With snow expected tomorrow afternoon, crews have been pre-treating the roads today and will continue this evening and tomorrow. #ARLwx

It might not be necessary with this storm, but Arlington County is urging residents this year to park in a parking lot or on the odd numbered side of local streets when it snows.
The county recently released the following video on the topic.

Luckily, the snow is not expected to start until well after rush hour — we all remember what happened the last time a light snowfall caught the region by surprise during the evening commute.
Regardless of the timing, it may be a good idea to stay off the roads during this first (potential) snow of the season.
Special Weather Statement…UPDATED
National Weather Service Baltimore MD/Washington DC
1110 AM EST Wed Dec 14 2016
…POTENTIAL FOR LIGHT SNOW ACCUMULATION IN THE WASHINGTON AND
BALTIMORE METROPOLITAN AREAS LATE THIS EVENING AND OVERNIGHT…
Snow showers are possible late this evening into the overnight across the Washington and Baltimore Metropolitan areas. Snow may coat the ground in some locations… and with temperatures near freezing this may cause slippery conditions. The best chance for snow will be between 10 PM and 2 AM late this evening into the overnight.
Update at 1:10 p.m. — VDOT says it is preparing for wintry weather tonight.
Crews are taking advantage of conditions today and Thursday to treat roads with anti-icing materials in northern Virginia, in anticipation of low temperatures through the rest of week and the potential for wintry precipitation over the weekend.
Throughout Fairfax, Loudoun, Prince William and Arlington* counties (*Arlington maintains own secondary roads) crews treat about 5,200 lane miles with liquid magnesium chloride or brine in advance of winter weather. This includes interstate, primary and high-volume secondary road roads, particularly ramps, bridges, and other critical areas prone to freezing.
The Virginia Department of Transportation asks drivers to keep an eye on the forecast for freezing conditions and precipitation. Before venturing out this weekend, VDOT reminds drivers to fill their gas tanks, slow down, to be aware of potential slick spots such as shaded areas and bridges, and to use the following resources:
- Check http://www.511virginia.org/ or the 511 mobile app before you go for traffic conditions and lane closures
- Follow @VaDOTNOVA on Twitter
- Visit www.virginiadot.org/ novaemergency for the latest updates and resources from VDOT in northern Virginia
- Get more details on snow removal in northern Virginia
This is also the perfect time to place or update an emergency kit in your car. Recommended items include:
- Water and food
- Ice scraper/brush
- Gloves and boots
- Phone charger
- First aid kit
- Ice melt/cat litter

An Arctic blast will drop temperatures into the teens and 20s in the D.C. area starting mid-week.
The cold air is expected to push into the area Wednesday night, and will bring with it wind and the possibility of some light snow.
The last time we saw snow in Arlington was when the remains of a giant snow pile in Ballston, left over from the January blizzard, finally melted. Unlike some past years, to our knowledge no flakes fell in November this year.
Are you looking forward to the first flakes of the season?
