10 years is not a large sample size, and the sample of bad years is even less. 2018-19 was one of the snowiest winters ever in VT, 19-20 was fairly average. Since then, we've had 3 bad snow years in a row. After 3 years of bad snow in Tahoe in the mid 2010s, people thought that the Sierra would never get a good snow year again and then they have gone on to break several snowfall records in recent years.

6 of the last 10 years have had above average snowfall totals in Burlington? I’m not sure what your basing your opinion on, but historically we are getting more snow… really depends on your time period.

From 1892 - 1965 we had 0 years with snowfall totals of 100” or more, since then we’ve had 10.

The last 50 years have had 35 years with above average snowfall. The prior 50 years had 18 years above average. The preceding 30 years had 8 years above average snowfall (normalized would be 14).
