since the season of 1900-1901, up to and including the season of 2018-2019 (top). Average decadal snowfall for 40 significant sites in the contiguous U.S. The dataīefore discussing the trends and reliability of the data, below is the table, based on reports culled from the National Weather Service NOWData website.įigure 1. For instance, in the high mountain areas of the West there are virtually no sites with a continuous period of record (POR) back to 1900, aside from Flagstaff, Arizona Donner Summit in the high Sierra of California and Red Lodge, Montana (which I did not include because of its obscurity). There is no complete record for Nashville, Tennessee Roanoke, Virginia Sheridan, Wyoming and Seattle, Washington, among other cities that would seem to be obvious choices.
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.).

Two seasons, 08 are missing, but based on surrounding observations they were likely not close to the top 10 seasonal snowfalls.Above: A snow-covered street in Boulder, Colorado, on Nov. Data between 2008-present is taken at the Bayfield Fish Hatchery just south of town. Snowfall records at the Spooner Ag Research Station go back to about 1893.ĭata goes back to 1939, with the observations between 1939-2005 taken at an observation site 6 miles north of Bayfield. Snowfall records for Brainerd go back to about 1948. Snowfall records for the International Falls area go back to about 1947, with some data also available between 19, though most of those seasons are missing parts of the winter season. ( More information about Duluth observation history.) Rank Snowfall observations have been taken at the property now known as the Duluth International Airport since 1941, with various locations closer to Lake Superior before this time period.

Note that not every location listed has a long history of weather records. The time range for the records below encompass from July to June of each season listed, not just the "meteorological" winter period of December-January-February. This page contains rankings of the top snowiest seasons for select locations. The Northland has had near record amounts of snowfall this winter.
