Updates: Corridor of snow sets up along Interstate 95 through D.C. area – The Washington Post

Scattered bands of moderate snow are focused west of the Beltway and most concentrated in the zone from Frederick to Leesburg.

Areas that end up under heavier bands could still pick up a quick coating to inch.

These hit or miss bands may be with us even well into tonight.

We’ll post another update around noon.

9:15 a.m. — Snow still going but easing slightly

Areas inside the Beltway and along Interstate 95 north to near Columbia continue to see snow but radar does show the band narrowing a bit and the intensity lessening.

Snow may continue in the immediate area another hour or so, and then should start to taper off unless the band redevelops. Areas to the north may see the snow subside a bit sooner.

Generally about 2-3 inches of snow have fallen in the immediate area since last night, pushing three-day storm totals into the 4- to 6-inch range.

After this band of snow fades, the snow isn’t necessarily over. While we’ll likely catch a bit of break, scattered snow showers could redevelop this afternoon into the evening, possibly even lingering overnight some.

Temperatures this afternoon should rise above freezing so any additional accumulation should mostly be grass and untreated roads. Well-traveled and treated roads should stay wet.

8:10 a.m. — Snow continues in narrow band through the metro area

A nearly stationary band of light to at times moderate snow continues passing through the heart of the metro area. It extends from Carroll County through Montgomery and western Howard counties through the District, eastern Fairfax County and western Prince George’s counties and into eastern Prince William and western Charles counties.

The snow could continue for at least another hour or two and another half-inch to inch is possible, with isolated new amounts up to two inches. The National Weather Service has extended the winter weather advisory from 9 a.m. to 1 p.m. due to the snow band.

Reports indicate main roads are fine due to temperatures near or even a little above freezing, but side roads are slushy and visibility is reduced. About one to inches of snow fell in many parts of the immediate area overnight.

6:30 a.m. — Snow band has set up along Interstate 95 corridor

A narrow band of light to moderate snow has set up through the immediate area, paralleling the I-95 corridor. This could remain stationary for a few more hours and produce up to an inch or two of snow accumulation, while reducing visibility and causing slick roads.

Our next update will be around 8 a.m.
