Updated forecast: Snow ending after coating to 2 inches, very cold tonight

This is our last update. Stay tuned for our PM forecast update for the forecast for tonight into tomorrow. That should publish by around 5 p.m. Otherwise, scroll down for our earlier forecast for the next few days.

12:45 p.m. update: Light snow continues falling in a strip from roughly Charlottesville through the D.C. area and up to Baltimore. Temperatures range from 30 to 35 degrees from northwest to southeast. While you may encounter a few slick spots in our colder areas well north and west of Washington, for the most part this snow is non-accumulating, except on grassy areas — very slowly.

So far, trace amounts (from downtown Washington south and east) to a couple inches of snow have fallen, with the highest amounts in our far north and west areas (there have been some isolated 2- to 4- inch totals). It seems like our snowfall forecast has worked out well.

Light snow may linger in the immediate area through mid-to-late afternoon before ending with little additional accumulation.. Toward Southern Maryland, the snow may linger into early evening and there might be a more moderate burst there that puts down a quick coating, mainly on grassy areas.

If you’re driving to a Super Bowl party this evening, the snow will probably have ended in most spots and we don’t expect widespread iciness on roads but an icy patch or two may be possible — especially in our colder areas.

9:45 a.m. update: Snow has tapered to just flurries or a mist for most of us, except for some light snow that will briefly linger south and east of D.C. Most roads should remain just wet, but take it slow on elevated surfaces like ramps and bridges, which could have a few icy spots.

Areas from around D.C. and I-95 and east could see another band of light snow between approximately 12:30 and 4 p.m., but temperatures should be warm enough to prevent any impact on roads, with maybe another dusting or so possible on the grass.

The National Weather Service has now cancelled the winter weather advisory for the entire D.C. area.

We may pause updates until steadier snow develops toward midday. Check back around then.

9:30 a.m. update: A somewhat persistent band of light snow covering D.C., near and along I-95, and just to the south and east is now giving some of those areas that missed out on the snow earlier this morning a very light accumulation mainly on grass. Temperatures are actually quite chilly, around 30-33F where currently snowing. But with the warm ground the past couple of days, not cold enough for icy spots, except for perhaps a few on elevated surfaces like ramps and bridges.

Elsewhere, radar is pretty quiet now for areas north and west of D.C. that saw a coating to 2 inches earlier this morning.

8 a.m. update: Scattered light snow showers should continue to linger into early afternoon. Most roads are just wet, but some icy spots remain possible mainly from around northern Montgomery, northern Howard, western Loudoun, and northern Fauquier counties to the north and west. The winter advisory remains in effect west of D.C. and I-95, but has been cancelled from D.C. and I-95 to the east, where temperatures are at or above freezing.

Here are some snow totals thus far from NWS and social media reports: Damascus (2.0″), Clarksburg (1.5″), North Potomac (1.1″), Columbia (1.0″), Olney (0.8″), Rockville, (0.6″), Silver Spring (0.2″), Warrenton (2.0″), Chantilly (1.1″), Ashburn (1.1″), Dulles (0.6″), Wolf Trap (0.6″), Herndon (0.9″), Falls Church (0.2″), Fairfax (0.2″), Reagan National (Trace).

And some pictures to go with the snow totals…

6:45 a.m. update: A period of heavier overnight snow left a coating to an inch of snow in many spots, with the highest amounts north and west of the Beltway, where some roads were briefly covered. But the remaining snow showers are light and roads are mainly just wet across the area now.

Scattered light snow showers should continue on and off into early afternoon, but should be light enough for not much more accumulation and mostly just wet roads across most of the DMV. That said, some slick spots are possible from around northern Montgomery, northern Howard, western Loudoun, and northern Fauquier counties to the north and west, where temperatures are currently 28-30F (see recent temperature map below, courtesy Weather Underground).

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

5/10: A rude return to winter with a little snow and much colder. Slight improvement as lingering snow showers taper midday and sunshine tries to peek through later in the afternoon.

  • Today: Light snow and snow showers gradually taper. Highs: Mid-30s.
  • Tonight: Partly cloudy and cold. Lows: Mid-teens to mid-20s.
  • Tomorrow: Early snow shower? Breezy. Highs: Low to mid-30s.

Winter has returned, with a little snow today, and much lower temperatures through tomorrow with highs only in the 30s. Temperatures trend closer to average on Tuesday, rising to the 40s, before returning to above-average territory (in the 50s) on Wednesday. Our next storm looks like rain on Thursday, when highs could reach the 60s.

Today (Sunday): Light snow or snow showers taper late morning into early afternoon from west to east. A dusting to 2 inches is most likely (highest north and west, lowest south and east), particularly on grassy surfaces. Even with morning temperatures near freezing, the warm ground leading up to the storm should limit accumulation on paved surfaces, but proceed with caution regardless, especially north and west of D.C., where it could be a little snowier and colder.

Afternoon highs reach only the mid-30s with wind chills mainly in the 20s to near 30, as a wind from the north occasionally gusts near 20 mph. Confidence: Medium

Tonight: Skies are partly cloudy with very chilly low temperatures bottoming out near dawn in the mid-teens to mid-20s. Northerly winds around 10 mph, gusting near 20 mph, keep wind chills mostly in the teens. Some patchy icy spots are possible in those areas where snow accumulated and melted a bit during the day; even if it looks darker and simply wet, it may in fact be “black ice.” Confidence: Medium

Tomorrow (Monday): Other than a morning snow flurry or quick snow shower, we should have partly to mostly sunny skies much of the day. It’s still wintry and chilly, though, with high temperatures about 15 degrees below average, in the low to mid-30s. Northwest winds gusting near 25 mph a few times help keep wind chills in the 20s. Confidence: Medium

Tomorrow night: Skies are mostly clear and winds should calm. Lows again range from the mid-teens in our colder suburbs to around 20 to the low 20s downtown and inside the Beltway. Confidence: Medium

With high pressure very much in control on Tuesday, sunshine helps warm us a bit closer toward average, with highs near 40 to the mid-40s. Southwesterly breezes probably remain light, helping us stay fairly comfortable for mid-February. Overnight lows trend a bit warmer, only dropping to the upper 20s to low 30s under fairly clear skies. Confidence: Medium

Wednesday should start off with a good deal of sunshine, with perhaps increasing clouds later in the day ahead of the next storm system eyeing our region. We should stay rain-free, though, with highs in the 50s as a milder breeze comes from the south. The early outlook for Thursday is even warmer with highs 60s, but with rain possible. Confidence: Medium
