The amount of snow that will fall and accumulate will depend on "the location, location, location," said Matt Ritter, meteorologist at NBC Washington. The system will introduce very variable conditions; Forecasts predict significant snowfall in the north and west of the distribution chain, as well as all precipitation in the south and east. Here is what you need to know.

With the spring being almost two weeks away, it makes sense that what might be one of the last waves of the winter season will be a complex trio of snow, rain and sleet. And this mix could linger on the roads by Monday, which would make the journey easier.

Snow has started to fall in most areas around noon Sunday, but the amount of snow that will fall and accumulate will depend on "the location, location, location," said Matt Ritter, meteorologist at NBC Washington. The system will introduce very variable conditions; Forecasts predict significant snowfall in the north and west of the distribution chain, as well as all precipitation in the south and east.

Shortly before 1 pm, the closest locations to the Interstate 81 corridor began to receive moderate to heavy snow. Ritter stated that most of these locations are currently neither dry nor hot, resulting in some accumulation. "In Montgomery County, head west towards Fauquier – that's where the snow changes," Ritter said.

As is the case with most of these winter storms at the limit of rain and snow, the altitude will make a big difference as to the amount of snow accumulated. Most of the lower level areas to the south and east of the district will remain too hot to allow accumulation of deposits.

Frederick County has started to get snow too, reports Dave Dildine, a WTOP Traffic reporter. Although there is no accumulation yet, some roads are wet.

Four to five inches of snow is forecast for central Maryland and Virginia along Interstate 81, with locally higher quantities.

As for D.C., it will be a tussle between masses of cold and hot air during most of Sunday, which will control the total snow, but to make a potentially very smooth ride on Monday morning.

A coating of up to 1 inch is expected in the south and east and suburbs.

Warnings, watches and notices:

A winter storm warning has been published for the following parts of the WTOP listening area:

In Maryland: Counties of Frederick and Carroll until Monday at 4 am, as well as the counties of North Montgomery, North West of Howard, North Baltimore and North West Harford from 2 pm. Sunday at 4am Monday.

In Virginia: Loudoun County of the Northwest until 4 am on Monday.

A winter storm warning means that severe winter weather will make the trip very dangerous or impossible. If you must travel, keep an extra flashlight, food and water in your vehicle in an emergency.

A winter weather report has been published for the following parts of the WTOP listening area:

In Maryland: In southern Montgomery, in southeastern Howard and in southern Baltimore, as well as in the city of Baltimore until Monday at 4 o'clock.

In Virginia: North Counties of Fauquier and Rappahannock until 2 pm Monday, as well as southeastern County of Loudoun until 4 am on Monday.

A winter weather advisory means that periods of winter precipitation will mainly cause travel difficulties. Expect slippery roads and limited visibility, and be careful when driving.

A low pressure system crossing the Carolinas to the north will send alternating gusts of snow and rain into the BC region until the night of Monday.

What will likely result in several inches of snow north and west of the city, as well as light rains in the south and east, will be a little more complicated for the district itself.

"The most significant impacts will occur in the north and west of British Columbia – think of a line connecting Harrisonburg to Dulles Airport and Baltimore, heading northwest, where "It will be a snow-covered event," said NBC meteorologist Lauryn Ricketts. "The areas south and east of China – think of a line connecting Culpeper to the Quantico Marine Base in Annapolis – will probably all be rainy."

Do not be too excited to see white flakes in the district, though, Ricketts explained – it will not last long. Washingtonians can expect a winter mix to switch between snow and rain for most of the afternoon to melt the snow that sticks.

"The metropolitan area of ​​D.C. will follow this rain-snow line," added NBC weather forecaster Somara Theodore. "As a result, snowfall, sleet and rain are likely to start quickly as temperatures drop on Sunday night, so they could become snowy again before they leave early Monday morning."

For central Maryland and northern Virginia, particularly in the highest regions of highways 81 and 66, forecasts of 3 to 4 inches are planned until Sunday evening. Northern Maryland, located along the border between the states of Pennsylvania, displays the highest total, where it could fall up to 8 inches on Monday at dawn.

"These areas will be the places where the roads will be the worst for the afternoons and evenings," Ricketts said. "Mixed areas should expect mainly wet roads with some snow-covered secondary roads, especially for counties closer to the warned areas."

While snowfall in California will have little more than what the NBC Washington weather team often calls "conversation," it does not take much for roads to slip.

Although no security warnings or warnings were issued for the downtown area on Sunday afternoon, the meteorological service still reported a possible icy road on Monday morning, with temperatures expected to drop in the wake of storm.

"Temperatures in this region are expected to remain in the mid-1930s across [Sunday evening], which should significantly reduce the impacts on transport, "said the National Meteorological Service in a special weather report. "However, temperatures will drop below freezing after midnight tonight, and the roads could become sluggish with icing due to daily Monday morning commutes in and around Washington DC."

Areas of Virginia and Maryland covered by warnings and warnings are more likely to see snow-covered roads, and therefore larger problems on Monday. A possibility of ice pellets and freezing rain could also make the road conditions particularly dangerous at altitude in central and western Virginia.

The exit of the storm will result in a cooler air mass than average for this time of the year. Daytime temperatures range from 30 to 30 ° C for most of the week, and nighttime minimums are felt until adolescence.

On the positive side, at least it will be dry: "Monday will be dry but will become sunny and windy," Ricketts said. "The winds will blow up to 25 to 30 mph tomorrow during the day. This will help dry out the roads during your Monday, so your evening commute should be A-Ok. "

Provide:

Sunday: Mix of wet snow, rain and sleet for the DC metropolitan area. Rain for all central Virginia and southern Maryland. All the snow for the far northern and western suburbs, sometimes becoming heavy tonight, regardless of rainfall. type.
