Baltimore Snow Outlook Strengthens as Models Show Sunday Support

Baltimore’s Sunday snow forecast is gaining model support but remains uncertain. Ensemble guidance (Canadian GEM, ECMWF ensembles, and AI ensembles) shows a real chance of accumulating snow, with roughly 35–50% odds for 1 inch or more depending on the model, and about 15% for 6 inches in some Canadian runs. Forecasters caution against relying on forecasts more than 3 days out and note a coastward track with cold air in place, while Presidents Week climatology adds context.
