I'm guessing that you do not live in a location which regularly sees substantial snowfall. If you did you would realize that, at least with current models, this would be pretty much impossible. Snowfall amounts are one of the most difficult things to model and are notoriously incorrect.
Unlike precipitation like rain, where the density is always the same, with snow the ambient temperature and humidity level play a huge role in determining how dense the snowfall is (heavy wet snow vs light fluffy snow). We can predict the amount of water which will fall from the sky during a snowfall with the same probabilities, amounts, and accuracy as with summer rains (which we're reasonably good at). The problem is that depending on the density of the snow (which is much harder to predict) that same amount of water can give a snowfall of between 5 and 20 inches.
