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.).

25-26 gave Boulder 22” of snow and 1.47” of liquid equivalent-which shows that the 10-to-1 snow-to-liquid ratio that was often used to extrapolate snowfall amounts decades ago can seriously underestimate snow totals. © 2023 NYP Holdings, Inc.Above: A snow-covered street in Boulder, Colorado, on Nov. Just days before that small snow sprinkle - not enough to even think about a snowball fight - the city broke a 50-year record for the longest seasonal drought without snow. The city boasted its first measurable snowfall at the start of February, when barely a half-inch of snow covered Central Park. The winter in Gotham has mostly been unseasonably warm - and noticeably lacking in snow. “May have rain mixing in with the snow at times so even that will cut down on snow totals at Central Park.” The forecast calls for 1 to 3 inches of snow that could reach NYC Monday night. “A lot of that melts on contact and it’s hard to get to actually stick or pile up,” Rawlins said.
Temperatures Monday night will be in the mid-30s - ensuring the snowfall won’t likely lead to major issues, said Rawlins. “The early Tuesday morning commute could be slow going,” he said, with most of the white stuff stopping by 9 a.m. The forecast has a winter storm brewing for the Northeast. The first snow will begin between the evening commute and midnight, Rawlins said - and keep dumping into Tuesday morning. Long Island could also see the same snow totals as the city, with the Hudson Valley possibly getting between 3 and 8 inches - depending on how far north the storm churns. “So for the city, we’re in the 1-to-3 (inches) range.” New Yorkers have not had to battle a heavy snowfall this year. “New York City is going to be right on the sort of the dividing line between nuisance snow and no snow at all,” said Fox News Weather meteorologist Mike Rawlins. Northern suburbs could expect heavier totals as the storm cranks up. With Old Man Winter running out of time to pack a snowy punch, the city could get 1 to 3 inches of accumulating snow when a winter storm gets underway Monday evening. The Big Apple is bracing for its biggest snowfall of the season as a storm approaches with just a few weeks left in a winter where flurries have been a rare sight.
