We have received a lot of questions about how to properly measure snowfall. Here are some guidelines:
The best thing to do is find an area that isn't blocked by fences or buildings, etc. You also don't want to pick the windiest spot in your area.
Over a large area, measure the snow in many different spots. Hit spots all throughout the area. Then, combine all the measurements and take the average. The more readings you can take the better.
With strong winds, getting a very accurate measurement is quite difficult. However, if you get many readings and take the average, that should give you a basic idea of the overall snowfall.
