*Winter Weather Advisory through 11 a.m.* | Snow Totals from NWS | Light snow delays school opening; federal government open with liberal leave in effect *

Update, 9:00 a.m. - Just very light snow and flurries linger, but the National Weather Service has extended the winter weather advisory until 11 a.m. as untreated roads remain snow-covered and slick.

Update 7:30 a.m. - One more patch of light snow showers is cycling through as the upper level disturbance departs. Flurries may linger a bit longer, into mid-morning or so. Little or no additional accumulation is expected.

Update 6:20 a.m. - Radar shows light snow showers moving out of the region from northwest to southeast although flurries could linger another hour or two. Be VERY careful commuting and allow extra time...untreated roads are snow-covered and, while this is by no means a crippling storm, slicks conditions are fairly widespread. Main roads are well-treated and in good shape.

For area snow totals, see the National Weather Service summary, in our comment area below (report yours!) and/or our Twitter feed. Southern St. Mary’s county seems to be the snowfall winner with confirmed reports of 3 inches and unconfirmed up to 4.5 inches.

Update: 5:30 a.m. - Light snow showers continue over the D.C. area and should last for another couple of hours, slowing the a.m. commute. This is not a high impact storm, but flakes are sticking to all untreated surfaces. Snowfall totals are generally around 0.5-1 inch, although 1-3 inches have fallen in some spots south and southeast of the District.

Many schools have two hour delays or closings. Here is a partial list. 2 hour delays: Fairfax, Howard, Frederick, Prince George’s, Loudoun, Anne Arundel, and Montgomery county. Closed: Stafford, Fauquier, Prince William, St. Mary’s, Calvert and Charles county.

From 5:00 a.m.: While a few flakes in the air may warm the hearts of snow lovers, lets hope not enough to cause traffic issues. I promise not to gripe here and, instead, say if this were Minneapolis, it would be a nice day. Yeah, I didn’t buy it either.

We are not likely to get above freezing until Saturday at the earliest, a stretch we haven’t suffered through since 2005. The snow event on late Friday looks light. The rest of the weekend is nicely sunny but still unrelentingly cold.

Today (Thursday): There are still likely to be some snow showers (40% chance) in much of the area at daybreak but should not add much to the amounts from overnight. By midday the clouds rapidly dissipate. Winds then pick up from the north at 15-20 mph making for wind chills in the teens all afternoon. Confidence: Medium

Tonight: The stars come out for the evening but the chill keeps admirers few. Breezes are still brisk enough to pain anyone not well bundled. Lows drop to the upper teens city, lower teens suburbs. Confidence: Medium-High

Tomorrow (Friday): The skies cloud up quickly in the morning. Breezes are much lighter, easing the chill but highs are not likely to do better than upper 20s to near freezing. Clouds thicken in the afternoon. Snowflakes are unlikely to fall until dusk (40% chance) but this may be just in time to complicate the commute home. Confidence: Medium

Tomorrow night: The best chance for snow comes in the evening, ending by about midnight (60% chance). The storm struggles to get its act together until offshore and accumulations are probably on the light side. We will have more details on expected amounts later today. Lows fall to the upper teens to lower 20s. Confidence: Medium


Saturday clears out nicely but winds in the wake of the storm keep it chilly. Most areas should make a run for the freezing mark and many spots get there long enough to melt off our snow coverlet. Be sure to look to the east after sunset for the rising of the full moon, known as the “Wolf” or “Ice” moon. We may not have the wolves to howl but it will feel icy with lows in the mid-teens outside the beltway to near 20 downtown. Confidence: Medium-High

Sunday is a quiet one. Very little wind and plenty of sun with highs mainly in the mid-30s should not be too bad as we are getting acclimated to our taste of winter. A clear night only results in lows in the 20s for a change. Confidence: Medium-High

Monday is likely to to see increasing clouds but precipitation is not likely with only a 20% chance of late day showers, of the liquid variety, as highs are finally likely to make a break back to seasonable levels in the low-to-mid 40s. That might actually feel good after all this! Confidence: Low-Medium
