A Winter Weather Advisory has been issued by the National Weather Service, as wintery mix of rain and snow moving into the D.C. region.

Snow is expected to fall across the D.C. region this weekend for the second time this December, bringing slick roads, gusty winds and low temperatures in the teens.

Conditions begin to change Saturday evening as a rain and snow mix develops, changing to all snow overnight.

“Expect slick roads and sidewalks and snow to accumulate on the grass and untreated surfaces first,” 7News First Alert Meteorologist Mark Peña said. “It is recommended to delay or avoid travel in the early morning hours.”

Snow showers may linger on Sunday morning, especially east of I-95. Behind the Arctic front, strong northwest winds gusting up to 40 mph will send wind chills in the single digits. Sunday afternoon temperatures will stay near freezing.

Sunday night lows fall into the upper teens to low 20s, with wind chills near zero.

Even after the snow ends, brutal cold weather lingers. Monday will be partly sunny but frigid, with highs only reaching the upper 20s to low 30s.

Peña said, “The bus stop and morning commute will be very cold and those outside should dress in many layers and cover exposed skin to protect from frostbite.”

Road crews preparing, officials urge drivers to stay home

Alex Liggett with Virginia Department of Transportation says road crews have been pretreating interstates, primary roads and high-volume secondary roads since Friday.

Charlie Gischler with Maryland State Highway Administration urges drivers to avoid travel if possible.

“Your best bet is to just stay off the roads Saturday night into Sunday,” he said. “If you do have to go out, remember to slow speed down.”

D.C.’s snow coordinator Warnique West reminded drivers to give snow trucks space and staying at least six to 10 feet back so crews can work safely.

Temperatures will finally climb back above freezing by Tuesday.

Just last week, the first snowstorm hit the D.C. region in December for the first time since 2017.
