* Winterwetterberatung along and west of Interstate 95 from 19.00. Sunday until 10.00 am Monday | School delays *
- After a blanket of snow, most places have turned to sleet and sleet. (In northern Maryland, snow can persist until dawn as the predominant type of precipitation.) This wintery mix makes for a smooth overnight journey, especially on untreated roads and sidewalks. Pedestrians and car drivers should exercise caution.
- On Monday morning, mixed rainfall and slippery roads are likely to be north and west of downtown Washington. From downtown to south and east, temperatures above freezing should allow for mostly smooth rain and wet roads.
1:35 am – Winter mix falls in most areas. Expect smooth spots overnight.
The snowmelt line has now risen north to Columbia (MD) (and should slowly continue north). The snow is now mostly confined along and north of Interstate 70, with a wintry mix in the south.
For most of the Washington area, the snowfall of this event is over and we now have only sleet and frozen rain for the rest of the night. At some of our milder spots, mainly from the city center to the southeast, precipitation can change in simple rain.
Throughout the night and into the morning, we expect the most prevalent slippery conditions in our colder areas west and northwest of the Beltway. Nevertheless, despite the temperatures around the freezing point, smooth spots are still to be expected in the immediate subway area and the mixture of frozen precipitation. Our biggest concern is on sidewalks, driveways, parking lots and neighboring streets.
This is our last update tonight. Scroll for the forecast until tomorrow. Check out at 5pm on Monday for our next detailed forecast update.
10:55 am – The snow has changed from the District South to sleet and icy rain.
In the immediate metro region, the snow fell for some time strongly, but the snowmixing line rose to the north (faster than projected by models) and has many areas of the Beltway South. Now, sleet and freezing rain were changed. This means that the accumulation of snow is mostly over, but we have to deal with a smooth layer of sleet / ice rain on the mushy snow cover that has fallen. Side streets and sidewalks will be the main problems.
10:15 pm – Snow falls hard and fast, some smooth spots emerge
it started to snow in the past hour, the intensity increased rapidly. As a result, temperatures could quickly drop to freezing and provide snow for the shading of grasslands and even untreated sidewalks and streets in the neighborhood. The main roads have been doing well so far. Be careful when traveling.
Short-range models and radar indicate that the snow should drop evenly for at least two to three hours, but probably not as much as the opening shock. However, in some areas, the total amount may exceed one inch and enter the boom area. At the same time, we have to observe an area of sleet and rain in the south (with the exception of freezing rain with temperatures below 32 ° C), which will rise north over time and limit how much snow can accumulate during the night – except in the north of Maryland
Here are some pictures …
21:30 – Snow has quickly overshadowed the immediate metro area
In the last 15 to 20 minutes we have a flood of reports on the Development of snow from the district received west. And it does not take long for the snow to drop a pretty quick clip.
We have received reports of snowfall in Arlington, Burke, Alexandria, Vienna, Fairfax, parts of Montgomery County and even Southern Maryland.
In the next hour, snow should begin to fall even in our eastern areas.
The snow will initially stick to mulch, car roofs, and grass, and then begin to coat untreated paved surfaces fairly quickly. So be careful when walking and driving.
20:25 – Snow Formation in the Western Territories
Radar shows snow formation in the western part of our region from Frederick and Leesburg and west through the corridor of Interstate 81. We have reports of light snow in Winchester as well as from Round Hill and Purcellville in western Loudoun County.
This snow should extend east to the counties of Montgomery, Eastern Loudoun and Fairfax over the region. Next hour.
Detailed forecast from 18:30.
The next 36 to 48 hours will be messy. A battle zone between warm and cold air will essentially halve the DC area, as will several rainfall rounds. That means we have the full range: snow, sleet, icy rain and just rain. Expect more in the night hours on Sunday, which on Monday morning will create slippery conditions on the roads despite the lack of accumulation.

Until Sunday evening: Over the next few hours, it remains cloudy before light precipitation erupts between 8 and 23 o'clock. It is expected that there will be light snowfall at the beginning of the precipitation, although the limit temperatures are between 32 and 36 degrees. Snow should be switched to a sleet / freeze-rain / rain mix sometime after midnight, with DC and South / Southeast locations first having to switch to and north / northwest locations hanging the longest on light snow.
The accumulation of snow / sleet / ice should be limited mainly to grasslands around DC, as road temperatures should usually remain high enough to avoid strong buildup. In our colder areas, untreated roads and sidewalks are the best way to get smooth and icy, and pedestrians and motorists should be careful. Depending on the location, lows end at 32 degrees and light winds with light winds from the southeast.
Morning (Monday): Smooth and icy spots in the morning, especially north and west of DC Light rain / ice cold rain persists Early in the morning, commuting increased. In the late morning we should take a short rain break, before in the afternoon more precipitation forms in the form of rain. High temperatures range from the middle to the upper 30s.
Rainfall is expected to resume on Monday evening, possibly returning to a mix of sleet and freezing rain later in our colder climates, possibly causing commuting problems on Tuesday mornings. The lows are around 32 degrees.

Hail at Pebble Beach: The legendary Pebble Beach Pro-Am tournament was interrupted for more than an hour on Sunday after a brief hail attack on Sunday. A small but intense storm cell happened with rain, thunder and hail directly above the golf course. After it was over, it looked like a winter wonderland.
The unusual weather was part of a large and powerful storm system that cycled along the Pacific coast at the weekend. Other highlights of this storm included the Snow Depth he had drained in the Sierras, and of course Seattle's version of Snowmaggedon .
