10 a.m update: If you woke up late and were missed by the narrow stripe of more consistent snowfall (and higher accumulations) to the south of D.C. (i.e., Culpeper, Stafford, Charles, and Calvert counties), you might wonder if it snowed! The last of the flurries have departed, and some sunshine has even peeked through. Accumulations on the order of a dusting or less to the north peaked out around 1-2” in the thin band to the south. Most spots finished in the dusting to 1” range. Temperatures now rising past freezing should get some boost from the quick end to precip and any bits of sun, so nearing the high end (or higher) of the range for today’s highs seems a good bet.
8 a.m. update: Snow is really starting to taper off now, except in the far southern suburbs from around Culpeper through Stafford and St. Mary’s counties. Most spots south of central Montgomery county have seen a dusting on grassy areas (this image from Fair Lakes, Va. is probably pretty typical of what has fallen in the metro region, submitted by @LiliMcDonald via Twitter), with some higher amounts in the range of 1-2” in Culpeper, Stafford, Charles, and Calvert counties. Just flurries were reported north of central Montgomery county.
6 a.m. update: Light snow (with some embedded patches of moderate snow) is falling throughout the metro region. Many spots have seen a dusting or so, mainly on grassy areas, tree limbs, and car tops. Temperatures have fallen to 30-32 degrees, which may allow for a few slick spots on roads (especially ramps, bridges, and overpasses) for the next couple hours - but most accumulation will remain on the grass. After around 8 a.m., snow should diminish in coverage and intensity and temperatures should gradually rise above freezing. Our forecast of a dusting to an inch mainly on grassy areas seems on track.

I wish I had warmer news to bring in the wake of this morning’s wintry brush. Instead, it’s a rather cold week ahead with another chance of snowflakes come early Wednesday morning (did somebody go a little overboard with their snow dance?). Our normal high is around 60 but we’ll have trouble breaking much into the 50s through midweek. Although in degrees Kelvin today’s highs should be into the upper 270s (does that help warm you up?).
Today (Sunday): Who’d have thunk it’s late March waking up this morning? A fresh dusting of snow for some and temperatures feel more like February. Lingering snow showers end this morning and clouds work out of the area during the afternoon. Even with the late sun, our temperatures don’t warm up much, with highs in the upper 30s to low 40s. Winds blow from the north at 5-15 mph. Confidence: Medium-High
Tonight: We’re looking at a pretty chilly night with mostly clear evening skies and light winds. Any lingering snow accumulations (most likely south and/or southwest of D.C.) will only aid in our overnight cooling. Lows fall to around the mid-to-upper 20s and clouds may increase again toward morning. Confidence: High
Any more flakes coming up? Keep reading for the forecast through midweek...
Tomorrow (Monday): Strong high pressure way back over the upper Midwest/southern Canada struggles to gain hold over us as another weak system slips by to the south. The high should be just strong enough to keep precipitation (this time it’s rain) to our south. Some high clouds may filter the sun in the morning and early afternoon with clearing thereafter. Our price for escaping the precipitation? More cold, with highs only in the mid-40s to near 50. Confidence: Medium-High
Tomorrow night: Temperatures once again dip below freezing most spots overnight. With mostly starry skies, crisp is the word I’d use to describe conditions. Lows bottom in the mid-20s to near 30 (suburbs to city). Confidence: Medium-High
Tuesday dawns plenty bright, and temperatures attempt to respond in kind. With mostly sunny skies, highs work their way slightly higher to the upper 40s to low 50s. Tuesday night, another area of low pressure begins to slide by to our south, and it could bring a chance of rain or a rain/snow mix overnight or toward morning. Overnight lows drop to the low-to-mid 30s. Confidence: Low-Medium
Precipitation is a pretty good bet Wednesday (60-70% chance as of now) with any rain/snow mix (snow accumulation doubtful except possibly far northwest) likely changing to rain in the morning. Temperatures remain on the raw side, in the mid-to-upper 40s. Confidence: Low-Medium
