We're still thinking light snow is likely tomorrow -- particularly between about 10am and 6pm in the metro area. Accumulations should generally be between a dusting and 1". Areas to the south of the beltway may get a little less, and areas to the north may get a little more. The snow may not accumulate much at all downtown due to somewhat warmer urban surface temperatures.
Temperatures will likely be at or below freezing when it snows so a few slick spots could develop on less traveled, untreated roads - particularly during any moderate bursts of snow, which may also briefly reduce visibility. Be particularly careful on bridges, ramps and overpasses.
No SchoolCast as I think the snow will start too late to impact schools.
