Erica's Answer:
And, as temperatures get colder, that snow/rain ratio gets even leaner. For instance, if the temperature is in the teens and we get 1" of precipitation, it would be equal to 20 inches of snow or more! So you can see why snowfall forecasting is so tough. We're trying to nail down exactly how much precipitation is going to fall in the form of snow, with accuracy within only a tenth of an inch!- Erica
