Below is a collection of weather models producing snow output. The model uses the forecast QPF (quantum precipitation forecast) and then applies a liquid to snow ration via the kuchera method. The lower the temperature when snow is expected, the higher the snow ratio and higher the snow forecast. If the temperature is warmer the snow will be heavy/wet and net a lower total.
