* Winter Weather Forecast along and west of Interstate 95 from 19h. Sunday at 10am Monday | School Delays *
Key Points
- After a blanket of snow, most places moved to slush and freezing rain. (In northern Maryland, it is possible that snow remains the dominant type of precipitation until the hours before dawn.) This winter set will make travel slippery, especially on untreated roads and sidewalks. . Pedestrians and motorists must exercise caution.
- For Monday morning commutes, mixed precipitation and slippery roads are likely to be north and west of downtown Washington. From the city center to the south and east, temperatures above the freezing point should mostly allow for rainy precipitation and wet roads.
Updates
– Winter mix falling in most areas. Expect slippery areas during the night.
The snow cover has moved northward to Columbia, Maryland (and is expected to continue to migrate slowly north). The snow is now mostly confined along Interstate 70 and north of it, with a winter mix to the south.
For most of the Washington area, the snow part of the event is over and there is only melted snow and freezing rain left. the rest of the night. Some of our sweeter areas, mostly from downtown to the southeast, could see the rains turn into driving rain.

During the night and the morning, we expect the most widespread slippery conditions in our coldest areas located to the west and northwest of the Beltway, but slippery areas are still likely in the immediate metropolitan area, given temperatures near freezing and the concoction of frozen precipitation. Our main concern is sidewalks, driveways, parking lots and neighborhood roads.
This is our last update tonight. Scroll the forecasts for tomorrow. See you Monday at 5 am for our next detailed forecast update.
– Snow turned into freezing and freezing rain from the southern district
The region of the immediate metropolitan area rained a lot of snow, but the snow layer swept northward (faster than expected by the models) and many areas of the south now changed to sleet and freezing rain. This means that the accumulation of snow may be largely complete, but we will have to deal with a smooth layer of freezing rain / freezing rain over the slush coat that has fallen. Secondary roads and sidewalks will be the main areas of concern.
from 10:15. – The snow falls violently and quickly, some slippery spots develop
Once it has started to snow during the past hour, the intensity has rapidly increased. This has allowed temperatures to drop quickly to temperatures near freezing and snow covers grassy areas and even untreated sidewalks and neighborhood roads. Until now, the main roads hold up well. Be careful if you travel.
Short-range models and radars suggest that snow should fall steadily for at least two to three hours, but probably less than what started at first. Even in this case, some areas may see totals greater than one inch, entering the boom. At the same time, we need to monitor an area of slush and rain (with the exception of freezing rain where temperatures are below 32) in the south, which is expected to move north with time and limit the amount of snow that can accumulate overnight, except in the north. Maryland.
Here are some pictures …
21:30 – The snow quickly covers the immediate metropolitan area
During the last 15 to 20 minutes, we received a lot of information about snow developing since the district to the west. And it does not take long for the snow to start falling fast enough.
We have received reports of snow falling in Arlington, Burke, Alexandria, Vienna, Fairfax, Montgomery County and even southern Maryland.
In the next hour, snow should begin to fall even in our eastern regions.
Snow will first attach to mulch, car roofs, and turf, then quickly enough to begin covering untreated paved surfaces. Therefore, caution should be used when walking and driving.
– Snow developing in our far western regions
A radar shows snow formation in the western part of our region, around Frederick and Leesburg, as well as to the west 81. We received reports of light snowfall in Winchester, as well as of Round Hill and Purcellville in western Loudoun County.
This snow is expected to begin to spread east in Montgomery, Loudoun and Fairfax counties at the following hour.
Detailed forecast beginning at 6:30 pm
The situation will become complicated over the next 36 to 48 hours. A zone of combat between hot air and cold air will essentially divide the region of the direct current, at the very moment when several precipitations of precipitation occur. This means that we are in the whole range: snow, slush, freezing rain and driving rain. Expect more alumni on Sunday night, which, despite little accumulation, will still create slippery conditions on the roads on Monday morning.

Until Sunday evening: Increasing cloudiness for a few hours before light rainfall begins to fall between 8 pm and 11 pm. Light snow is expected at the onset of precipitation, despite marginal temperatures ranging from 32 to 36 degrees. Snow should shift to a mix of rain / freezing rain shortly after midnight, with positions between DC and south / southeast being the first to pass, and positions north / northwest North West.

Snow / slush / ice accumulations are expected to be mainly limited to grassy areas around DC, as the road temperature should remain high enough to avoid substantial accumulation. In our coldest regions, untreated roads and sidewalks are best placed to become slippery and ice-cold, and pedestrians and motorists need to be cautious. The depressions will reach 32 degrees, depending on the location, with light winds coming from the southeast.
[ It will probably be cloudy tonight in the morning of Monday with slippery movements, delays]

Tomorrow (Monday): Ice and ice in the morning, mostly north and west of DC A pouring rain / freezing rain persists early in the morning, aggravating the movement problems. We should witness a brief lull in precipitation in the late morning before other rains occur later in the afternoon as rain.
Rainfall is expected to resume Monday evening and could eventually return to a mix of freezing rain / freezing rain at some point in our coldest regions, which would likely cause more travel problems for Tuesday morning. The minimums are accurate around 32 degrees.

Greetings to Pebble Beach: Participate in the Pro-Am Tournament on the legendary immaculate links of Pebble Beach, which were interrupted for more than an hour Sunday after a brief hail. A small but intense storm cell crossed the golf course with rain, thunder and hail. After its passage, it looked like a winter wonderland.
Unusual weather was part of a large and powerful storm system that swept over the Pacific coast this weekend. Other highlights of this storm include the snow feet dumped in the Sierras and, of course, the version of Snowmaggedon in Seattle. a mailbox? Subscribe here .
