A major snowstorm is forecast to hit the Northeast region of the U.S., including areas like New York City and Washington D.C. this weekend. It has been nearly two years since some locations in the Mid-Atlantic and Northeast have seen at least 1 inch of snow from a single storm. Forecast models show a potent winter storm is likely to develop, but uncertainty remains around details like the exact track, timing, and snowfall totals this far in advance.
