Discussion

A major coastal storm will spread a cold rain our way late Friday night into early Saturday and then the rain is likely to mix with and then change over to a heavy, wet snow. Accumulations are likely with the greatest chance of significant accumulations to the north and west of the District and in higher elevation localities where several inches can pile up. The weight of the heavy wet snow is liable to bring down some tree limbs possibly causing scattered power outages. The storm pulls away Saturday night and there could be a hard freeze for the first time this season by early Sunday morning. This unusual late October winter storm does not mean that we’ll stay cold from here on out; in fact, we could get back up to 60 degrees for highs by mid-week. Expected snowfall accumulations: 1-3 inches in the District; 3-6 inches in the N/W suburbs. An interesting tidbit: DC's biggest October snowfall was 2.0 inches in 1925 on the 31st.
