I'm also pretty satisfied with the forecasts on those numbers as well, within the bounds of what is reasonable to forecast. During big events, snowstorms and hurricanes, the local meteorologist will break the area I'm in into ~7 regions and give guidance like 'zones 5-7 will get 3-6" of snow, zones 1&2 12-18"' or '3-4 inches of rain north of 84'.
