For comparison’s sake, the latest official 30-year POR average (1981-2010) and the snowiest and least snowy single seasons are also included (bottom). Each city’s snowiest decade is highlighted in red and its least snowy decade in blue. This makes it easier to compare changes over time for cities that are within more or less the same regional areas. The city list is arranged in a general east-to-west and north-to-south pattern, following general regional areas such as “along the east coast”, Ohio Valley, Midwest, Plains, Rocky Mountains, and far West. ![]() 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.).

ET: This article has been updated to include comment from Berardelli.Above: A snow-covered street in Boulder, Colorado, on Nov. "While the days leading up to Thanksgiving and the holiday itself are expected to feature largely dry conditions across the mid-Atlantic and Northeast, conditions may quickly change as holiday shoppers head out in search of deals next Friday," AccuWeather meteorologist Brandon Buckingham said. Travel plans around the Thanksgiving holiday may also be interrupted by a "significant storm to form over the center of the country," AccuWeather said Saturday, adding that the storm could impact major travel hubs Chicago, Atlanta and New York. ![]() Receiving over 6 feet of snow, Buffalo, New York, and surrounding cities were slammed by a historic lake-effect snowstorm this weekend, with the Buffalo Bills moving their Sunday game against the Cleveland Browns to Detroit. The previous record was set in 2014 with 7.6 inches dropping during the historic and deadly "Snowvember" event that dropped close to 7 feet of snow on the area, AccuWeather reported.Ībove, a snow covered sign protrudes from the snow after an intense lake-effect snowstorm impacted the area on November 19 in Hamburg, New York. By mid-winter the lake gets icy, and moisture gets more sparse."īuffalo broke its record for the most snow in a single day with 16.1 inches falling on Saturday. Meteorologist and climate specialist Jeff Berardelli told Newsweek on Saturday, "The heaviest lake effect events happen in early winter or earlier as you can see because the lake is still warm. The air rises, clouds form and grow into narrow band that produces 2 to 3 inches of snow per hour or more," the NWS added. "As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere.
