The D.C. area's first significant snowfall in two years began in the wee hours of Sunday and blanketed the area, and additional snow showers are on the way.
Snow moved into parts of Virginia and Maryland before dawn Sunday and then quickly enveloped the entire region. The D.C. area is under a winter weather advisory. See all weather alerts here.
Most parts of the D.C. area got 2 to 3 inches of snow on Sunday. Scattered snow showers are expected Monday, with 1 inch or less of additional accumulation expected. Areas well north of D.C. are set to see more.
More snow was expected in the D.C. area, but we had more dry air than anticipated, Storm Team4’s Doug Kammerer said.
"As for [Monday], we are not expecting a lot of snow as the area of low pressure will be just a little too far north for us to get the good wrap around we need for a lot more snow," Kammerer said. "We will continue to see snow showers though with the best chance of accumulation to the north of D.C."

Some residents said they were delighted by the storm.
"Oh, I think it's wonderful to finally see snow," said Chris Spielmann, in the Tysons area. "We haven't seen snow in a long time. It's nice to see it coming down, and it takes away from the bleakness of winter, now that the holidays are all gone, and all the lights are off and the decorations are down. It's nice to see something festive."
On the National Mall, several dozen people met on Sunday afternoon for a snowball fight. The snowballs flew near the Smithsonian Castle.
At the National Zoo, the pandas adorably rolled, slid and tumbled on video.
Despite the weather, some people were out and about, including one man who said he was on the way to the gym.
"It's a little bit slippery, so just be careful," he said. "... A few spots, it's slick. My car slid a little bit. But if you drive cautiously, keep your distance, I think I'm good, you know?"

Bowser said the District Snow Team was being deployed to prepare for the snowfall. Crews spray a combination of brine and beet juice on streets to reduce the temperature at which ice bonds to the pavement. Additionally, 147 dump trucks apply salt to roads, highways, bridges and ramps throughout the city.
Officials in the city of Alexandria urged residents to stay off roads, not park on snow emergency routes, keep shovels and salt or sand handy, prepare an emergency kit and clear debris from around fire hydrants and storm drains, and to avoid shoveling snow into the street.
Prince George's County officials announced that all COVID-19 vaccination appointments booked for Monday through the county's portal have been canceled. People with appointments will be able to reschedule for a later day in the week.
