Arlington County is under a Winter Weather Advisory through 9 a.m. Tuesday.
A mix of rain, freezing rain, sleet and snow is expected to fall tonight, with the precipitation likely to start around 6 p.m. Up to two inches of snow may accumulate, though if temperatures stay slightly warmer there may be little to no snow accumulation, forecasters say.
JUST IN: We have slightly increased the amount of snow and sleet we expect in the DC region this evening, the bulk of it falling between about 6 and 11 p.m.

Both Arlington County and VDOT crews are pre-treating roads in advance of the winter weather.
“Crews are spot pre-treating areas in higher elevations today,” VDOT said. “About 400 trucks will be staging along roads this afternoon, ready to treat roads as precipitation begins. Tree crews will also be on alert in case of downed branches due to ice.”
With Arlington along the edges of freezing for expected overnight precipitation, crews are pretreating hills and overpasses this afternoon. Continued rains can wash away such solutions ahead of colder temperatures. Use caution if venturing out. #ArlWX https://t.co/JnvPU3tlvu pic.twitter.com/XrM5DDlExW
