IMO the mode is better suited for a situation such as trying to find what item at your candy shop sells the most.
In terms of snow, it may not be the best. For example, imagine a city has the following snowfall amounts in the last 10 years...21, 21, 54, 36, 41, 45, 48, 33, 28, 39. Those two dud years would make the most common total 21 inches, whereas the average is 36 inches. The real problem though is that when seasonal totals are reported to the decimal, it would be even less likely that two years would repeat the same exact number.
