I was surprised when NYC got there in 2016 - it took basically the perfect flow of cold air down the Hudson. For DC, all the snow around will help. But I will still be shocked if we get there.
not sure how other folks in the DMV are doing, but DC so far seems to have done a pretty good job with its "snow team". Every street in our neighborhood has seen a plow at least once.
as someone who remembers the several inches of sleet we got in PD2 in C'ville - this shit is not gonna melt for a long time. So that is the one plus side of sleet. The water content is much higher than snow lol.
