1:00 p.m. — Final update: Storm ends with peak totals in western, higher elevation areas, and lower amounts in I-95 corridor.

The storm is winding down across the region and temperatures should remain above freezing through the afternoon, allowing the coating to several inches to melt some. Snowfall amounts ranged from 1 to 4 inches in our western areas (and 4 to 6 inches in higher elevations), to a coating to 1-inch along and east of Interstate 95, including the District. A small area southeast of Interstate 95 in Southern Maryland saw up to 2 to 4 inches.

Forecast for the rest of the day: Expect some peeks of afternoon sun mixed in with lingering clouds, as highs reach near 40. The fresh snow will drip away as slush in many areas, leaving puddles on area roadways. Late this afternoon, winds should pick up from the northwest. Overnight, temperatures fall to near 20, meaning any wet and slushy areas will refreeze.

Stay tuned for PM forecast update later this afternoon.

Forecast from 5 a.m.

Today’s daily digit

A somewhat subjective rating of the day’s weather, on a scale of 0 to 10.

6/10: Morning snow may not be enough to satisfy snow-lovers, but it could come down nicely for a time, and at least we salvage a decent Super Bowl Sunday afternoon.

Express forecast

  • Today: Morning to midday rain and snow. Highs: Near 40.
  • Tonight: Clearing skies and cold. Lows: Upper teens to mid-20s.
  • Tomorrow: Mostly sunny, increasing clouds late. Highs: Mid-to-upper 30s.

Forecast in detail

Snow may come down moderately to heavy for a time this morning but may also struggle to accumulate more than a slushy couple of inches due to temperatures above freezing, and even that could be mainly on grass rather than roads and sidewalks. The sun returns tomorrow, but an active pattern persists with spotty snow and rain Monday night and Tuesday, and then another potential winter storm between late Wednesday and Friday.

Today (Sunday): Rain changes to snow around 5-8 a.m., and the snow could be moderate to heavy at times this morning, accumulating around one to four inches. With temperatures at or above freezing, much of the accumulation may focus on grassy areas, but paved surfaces (especially untreated ones) could become slushy and slick during any heavier bursts of snow. Snow should taper around 11 a.m. to 1 p.m., possibly changing to rain as it does. Afternoon highs reach near 40, leaving things a bit drippy as the late-day sun tries to peek out as well. Late-afternoon winds pick up from the northwest. Confidence: Medium

Tonight: A bit of a gusty early-evening breeze diminishes later this evening. But even with a light wind from the northwest, overnight lows drop to the upper teens to mid-20s overnight with clearing skies. That means a hard freeze is likely, turning any wet surfaces quite slippery, with wind chills well down into the teens. Confidence: Medium-High

Tomorrow (Monday): Sun fully returns to the sky on Monday, leaving us cold but somewhat pleasant in the sun. Afternoon highs should get to the mid- to upper 30s. That sun is fleeting though, with clouds increasing again by late afternoon or evening. Light winds from the north during the morning shift to come from the southeast in the afternoon. Confidence: Medium-High

Tomorrow night: Clouds thicken during the evening as low pressure approaches from the west. After midnight a light wintry mix tries to develop. With temperatures dropping to lows in the mid-20s to near 30, a light accumulation of snow, or a glaze of freezing rain, could make things slick by morning. Confidence: Medium

A look ahead

Winds from the south help temperatures rise quickly on Tuesday, turning any of that light wintry mix to all rain early in the morning. Some spotty rain showers remain possible through the day. On the whole, it’s a rather gray day, but highs peaking in the mid-40s aren’t terrible. Colder air returns again from the north Tuesday night, as skies stay mostly cloudy with lows in the mid-20s to near 30. Confidence: Medium

We get another quick break in the action on Wednesday, but “quick” is the operative word. We’re dry and mostly cloudy through much of the day with chilly highs in the 30s. But as our next system begins to approach, we’ve got a chance of snow or ice late Wednesday into Thursday. More details to come. Confidence: Low-Medium

Snow potential index

A daily assessment of the potential for at least one inch of snow in the next week, on a 0-10 scale.

7/10 (): SPI criteria of one inch within reach early Sunday, especially on the grass, though not a sure bet everywhere. But another chance of accumulating snow/ice to watch for late Wednesday to Friday.

Morning snow updates (expired)

11:40 a.m. — Big flakes for some as snow starts to wind down; temperatures at or above freezing

It’s been a nice final burst of snow in and around the Beltway with big flakes in some spots, although with temperatures at or a couple of degrees above freezing, it hasn’t added much in the way of additional accumulation. The snow has let up quite a bit in our far western suburbs, and will continue to do so from west to east during the next hour or so, possibly mixing with or changing to rain as it does.

Why the big flakes? Our winter weather expert Wes Junker explains, “Smaller flakes and crystals tend to stick together when your temperatures is near freezing. Also, where you have banding and stronger lifting, the snowflakes stay suspended longer [and grow larger] before they reach the ground.”

We’ll provide one more update with some snow totals during the next hour.

10:30 a.m. — Improving conditions north and west, one last burst of snow from D.C. to the south and east.

Highways and main roads that were snowy and slick north and west of D.C. are improving with temperatures now rising a degree or two above freezing, but side roads may continue to be slippery through around noon. The snow has stuck mainly to grass from D.C./I-95 to the east, with little to no accumulation in the warmer urban center of D.C. However, areas from D.C. to the south and east look to get one last burst of snow and a bit of accumulation (mainly on grass) during the next hour or so.

9:30 a.m. — Snow sticking to roads north and west, mainly to grass south and east

Most all of the greater D.C. area is reporting snow, some of it moderate at times, except for parts of lower Southern Maryland where is still some rain mixed in. The snow has been heavy enough and temperatures cold enough for the snow to stick to paved surfaces north and west of D.C. and I-95, with light accumulations mainly on the grass from D.C./I-95 to the east.

Generally we’ve seen around 0.5 to 2.5 inches of snow so far across much of the area (more north and west, less south and east). Recently reported accumulations include Centreville, Va. (2.5″), Herndon, Va. (1.5″) and Vienna, Va. (0.6″). Although very little has accumulated in the warmer urban center of downtown D.C.

Snow continues moderate at times but should start to let up around after 10:30 a.m. or so. Here’s a look at recent road conditions...

8:30 a.m. — Enjoy the snow while you can, it won’t last long; be careful on roads north and west of D.C.

Enjoy this snow while you can, and stay off the roads if you can for just a few hours, at least for those of you north and west of D.C. That’s where moderate to heavy snow and temperatures dropping to right around 32 have led to snowy and slick roads. We should see the snow let up from west to east around 10 a.m. to noon, with quickly improving road conditions, even as lighter snow or rain showers linger into early afternoon.

8:05 a.m. — Snowy and slick roads north and west of D.C., rain changing to snow south and east

We’ve got some snowy scenes across the area at this hour. Some snow accumulations reported as of 7 a.m. (so they would be a little higher by now) include Damascus, Md. (0.8″), North Potomac, Md. (0.3″), Reston, Va. (0.3″), Herndon, Va. (0.3″), Lessburg, Va. (1.0″), Dulles Airport, Va. (0.3″).

Many roads and sidewalks north and west of the Beltway are snowy and slick. Conditions are better from the Beltway and I-95 to the south and east, but even there roads and sidewalks could become snowy and slick during heavier bursts of snow. We’re still waiting for the rain to mix with or change to snow as you head further south and east of the Beltway.

Here’s a look at recent road conditions across the area...

7:15 a.m. — Snow-covered roads north and west of Beltway; rain changing to snow closer to D.C. and I-95

As the rain continues to mix with and change to snow from northwest to southeast, with snow now being reported even in some spots east of I-95, areas of heavier snow are covering roads north and west of the Beltway, from northern Montgomery and western Fairfax counties to the north and west. Road conditions should be the worst during the next few hours, improving after 10-11 a.m. as the snow starts to let up.

We’re still seeing that transition from rain to snow work its way south and east across the area, with snow now reported as far south and east as Arlington and New Carrollton. But for the time being, as you get closer to and south and east of the Beltway and I-95, temperatures are warm enough that most snow accumulation should be confined to grass. That could change as any heavier bursts of snow cool temperatures further.

6:30 a.m. — More accumulation on grass than pavement, but snow could still cover roads at times

We currently have reports of the rain mixing with snow as far south and east as northwest D.C. More and more of us should see the rain mix with or change to snow during the next hour. While we expect more of the predicted accumulation of one to four inches to occur on grass than on paved surfaces, roads and sidewalks could still become snow-covered during heavier periods of precipitation (as we’ve already seen in Leesburg), especially north and west of D.C. where temperatures are colder.

6 a.m. — Rain should mix with or change to snow from northwest to southeast

As forecast, most of us waking up this early have woken up to rain and mid-30s in the immediate D.C. area, with snow and low 30s to the north and west in Carroll, Frederick, and Loudoun counties, as well as reaching into northern and western Montgomery County. We should see the rain mix with or change to snow from northwest to southeast during the next couple of hours. Please keep reading for our full forecast...
