I only included places that see winter snowfall regularly (i.e., in most years), meaning along and north of a line from North Carolina through Tennessee, Oklahoma and the mountainous regions of the West.Ī constraining factor in choosing the sites is that they must all have a continuous monthly snowfall record dating back to at least 1900, something that a surprisingly few do. So, as a follow-up to that, I decided to look at how much snow has actually been measured decade by decade at 40 different cities/sites across the contiguous U.S. The basic conclusion was that no one really understands much about this. In the conclusion to that blog, I wrote a bit on how climate change may be affecting snowfall in the United States. In my previous post, I looked at record snowfalls for all the states and several cities for various periods of time (24 hours, monthly, etc.).
