Tysons, VA

(Updated at 3:40 p.m.) The D.C. metropolitan area could potentially get its biggest snowfall in two years starting on Sunday (Jan. 31), The Washington Post’s Capital Weather Gang predicts.

The National Weather Service issued a Winter Storm Watch for the region at 3:10 p.m. today:

…WINTER STORM WATCH IN EFFECT FROM LATE SATURDAY NIGHT THROUGH LATE SUNDAY NIGHT…

* WHAT…HEAVY SNOW POSSIBLE. POTENTIAL FOR 5 OR MORE INCHES OF

SNOW.

* WHERE…THE DISTRICT OF COLUMBIA, AND PORTIONS OF CENTRAL AND

SOUTHERN MARYLAND, CENTRAL AND NORTHERN VIRGINIA, AND THE

EASTERN PANHANDLE OF WEST VIRGINIA.

* WHEN…FROM LATE SATURDAY NIGHT THROUGH LATE SUNDAY NIGHT.

* IMPACTS…TRAVEL COULD BE VERY DIFFICULT.

The current forecast for the Tysons area suggests Saturday night will see clouds set in with a 30% chance of snow or other precipitation after 4 a.m. Chances of precipitation go up to 100% on Sunday, when snow is expected to start falling before 4 p.m. with some freezing rain possibly mixed in.

The NWS forecast suggest snow could continue through Monday with the chance of precipitation still at 50% that night.

As of 9:57 a.m. today, the D.C. area was expected to get three to four inches of snow between 7 p.m. on Saturday and 7 a.m. on Monday.

However, the Capital Weather Gang says this is a “complicated” storm, where total accumulation could vary from two to 12 inches depending on whether a coastal storm forms off the North Carolina coast and brings a second wave on Monday.

In preparation for the weekend, Virginia Department of Transportation crews have been treating roads in Fairfax County and elsewhere in Northern Virginia over the past two days.

The Fairfax Connector is advising passengers to plan ahead if they’re going to travel this weekend, noting that service could be reduced, modified, or suspended due to inclement weather.

“If road conditions become unsafe, icy or snow packed, service may be suspended on a route-by-route basis, or system-wide,” the Fairfax County bus transit system said. “Officials appreciate passengers’ patience and cooperation during weather events and encourage everyone to be prepared.”
