A mammoth blizzard is bearing down on the East Coast. While we won’t see anywhere near the worst of it here in Pittsburgh, we still could see our biggest snow of the season. Models and forecasts are split between a small accumulation and a significant half foot, with our magic number for Pittsburgh being 3-5″. Our PGH Snow Day forecast maps for the storm are below. Stay tuned for the Forecast Roundup, going live this evening at 5pm.
