text: Depends on where you live and how large an area the forecast covers.  Forecasts are for large areas and within those areas are microclimates determined by geography such as mountains, passes, large bodies of water (oceans, lakes, bays), altitude, et cetera.\n\nWhen I was a kid in Pennsylvania, the snow would always track north or south of where we lived so while other schools would get snow days, we'd only get an hour or two of snow delay.\n\nI watch the weather forecasts in the Northern California Sierras these days.  Just travelling up and down the mountain and in and out of town can change how much snow I see.  Sometimes the forecasters call for snow and we don't get as much.\n\nThe computer models can only provide a probability of snow and not forecast exact amounts in any given location.
