Germantown, Md. receives a quick, wind-blown dusting (Dan Stillman)

Overview: Snow showers, briefly heavy in spots and accompanied by swirling winds, are racing through parts of the region. Typically, as quickly as the snow starts, it shuts off, but sometimes there’s just enough to slicken roads. These should continue sporadically through the PM commute.

4:00 p.m. update: Snow showers have diminished in coverage and intensity, but some linger, especially to our northeast and southwest. See our PM Update for our latest forecast. This live blog has concluded.

Earlier updates

3:00 p.m. update: The snow shower activity has settled down with the exception of the eastern suburbs. Radar shows some snow in southeast Prince George’s county, in eastern Charles county, and sections of Calvert county. There also appears to be one near Annapolis in Anne Arundel county. This activity should wind down in the next 30 minutes. We’ll keep an eye on radar to see if anything more develops to the northwest.

2:30 p.m. update:The snow showers in Fairfax and Montgomery county have come and gone, but radar shows one in in northern Prince George’s county, another in western Howard county, and several in Frederick county racing southeast. As with the others, these may produce a quick dusting and a slick spot or two with temperatures near freezing or just below.

2 p.m. update: Two snow showers - one just east of Fairfax and one near Rockville - may drop a quick dusting before racing southeast. These snow showers last no more than 10-15 minutes.
