Pretty amazing what a difference 10 hours can make. This was taken Saturday evening, at about 6:30, on my way home. It's around mile 10.5, as I recall, and as you can see, the trail is clear. The whole stretch from Vienna to Falls Church was clear and dry, with the exception of the bridge over the beltway, which had some ice on the right hand side (heading east), but still had plenty of clear, open surface.
