D.C. snow updates: Snow blankets the region again with 2 to 5 inches expected

* Winter weather advisory until 7 p.m. for D.C. and south | Winter storm warning until 7 p.m. north of D.C. *

5:35 a.m. — Steady snow quickly covers roads as early accumulations approach or surpass an inch

The snow arrived on schedule around 2 to 3 a.m. in the DMV, quickly covering roads and sidewalks and turning them treacherous with temperatures in the mid-20s to near 30. Steady snow has already accumulated around 0.5 to 1.5 inches and counting. We now expect 2 to 5 inches (lowest south, highest north) from this storm across the region, with the heaviest snow falling now through around 9 a.m., then lighter snow at times into the afternoon.

The National Weather Service upgraded the winter weather advisory to a winter storm warning for areas north of D.C. (including Montgomery, Loudoun, Howard, Frederick and Carroll counties) due to the higher snow potential there.

Here are some early pictures and videos coming in…

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

4/10: Another delight for snow lovers, but not great for drivers or commuters.

  • Today: Light snow. Highs: Near freezing.
  • Tonight: Snow showers possible. Blustery. Lows: Teens to 20.
  • Tomorrow: Cold, blustery. Highs: Low to mid-20s.
  • Sunday: Sunny, still breezy. Highs: Near 30 to mid-30s.

About 1 to 3 inches is our forecast snow accumulation in the region, with a little more possible, seemingly focused on northern suburbs. Both rush hours today may have slippery roads, especially the morning one as snow should be ongoing for much or all of it. The weekend is very cold, with frigid wind chills, before we finally thaw out moving into next week.

Today (Friday): In the pre-dawn through sunrise period, light to sometimes moderate snow accumulates to around 1 inch, with snow-covered roads likely. Temperatures should be in the 20s to near 30. Mainly light but occasionally moderate snow persists into the afternoon, with snowfall totals ranging from 1 to 3 inches downtown and south, or 2 to 4 inches northward. Some treated main roads may be just wet or slushy with temperatures nearing the 32-degree freezing mark at times. Later in the afternoon, wind gusts near 20 mph from the northwest are possible. Light snow gradually tapers off from west to east late in the day. Confidence: Medium

Tonight: Any evening snow showers slowly taper into the night as skies turn a bit clearer with time. Northwest gusts near 20 mph may continue, blowing in colder air with mid-teens to near 20 degrees for low temperatures. Wind chills in the single digits or so. Confidence: Medium-High

Tomorrow (Saturday): Cold and blustery with wind chills remaining in the single digits and teens. Winds from the west and northwest could gust about 30 mph. High temperatures struggle to reach the low to mid-20s under a mix of sun and clouds. A stray snow flurry or shower is possible. Confidence: Medium-High

Tomorrow night: Wind gusts from the northwest around 25 mph remain possible essentially all night as skies turn mostly clear. Low temperatures probably bottom in the teens for the entire region, with wind chills easily in the single digits. Confidence: Medium-High

Sunday: Wall-to-wall sunshine and blue skies are possible, with an outside chance of a couple of low morning clouds here and there. Don’t let sunshine fool you through the windows, though, with some wind still chilling our near 30 to mid-30s high temperatures. With gusts from the northwest eyeing the 25-mph mark, wind chills may get no warmer than the low 20s. Continue to bundle up. Confidence: Medium-High

Sunday night: Clear skies and light breezes trend downward toward fully calm by dawn. Low temperatures bottom out in the teens throughout the region. Confidence: Medium-High

Sunshine dominates one last day Monday before a possibly prolonged cloudy period heads our way. Light breezes from the south and southwest start transporting above-freezing air into our region as high temperatures eye the mid-30s to low 40s. A small tweak to high temperatures is possible as we get closer and see when and how strong “warmer” breezes shift into the region. Confidence: Medium-High

Slowly increasing clouds are likely Tuesday, with a stray rain shower possible by late afternoon. Light breezes from the southwest continue to pump in milder air, with high temperatures aiming within a few degrees of 45. Our thaw really gets underway. Confidence: Medium

A daily assessment of the potential for at least 1 inch of snow in the next week, on a 0-10 scale.

9/10 (): Very reasonable to expect at least an inch of snow accumulating across the region. Looks like about 1 to 3 from downtown southward and 2 to 4 north.
