This model snowfall forecast map shows just how much amounts might vary across the D.C. metro area. (StormVistaWxModels.com)It took almost the entire season, but the D.C. area finally has a legitimate shot at a significant snowstorm late Monday into Tuesday. If the heavier amounts of snow materialize, then travel Monday night and Tuesday could become difficult, with many delays and cancellations. The storm tracks too far west, bringing in warmer air which would limit snow accumulations or primarily produce rain. The lows positioned toward the center of the green would probably result in a big snowstorm for the entire metro area.
