Measuring snow from one location will vary from one location to another. I used to ask a coworker how much rain he had and we compared it sometimes he had more than I did and sometimes he had less then me. And we live 1 mile as the crow flies to his place. I think the same can be said with snowfall. Your not gonna get an equal amount put down exactly everywhere. Just like Thunderstorms in a 1/4 mile range someone will get 1.5in and the next person will get 0.
