Pretty detailed discussion about why I feel the heaviest snows verified southeast of my forecast. Basically, had the system been about 12 hours further along in its evolution, the H7 low would have been closed off, and that forcing would have been displaced to the north. But since it had only closed up to H85mb, the most intense forcing focused at that level...which is obviously further southeast.
