How Early or Late Can Snow Fall?

How Early or Late Can Snow Fall?

Making weather predictions would be a whole lot easier if the seasons would just behave the way they were supposed to. Winter doesn’t officially begin until December 21 this year, but that doesn’t mean wintry weather won’t arrive ahead of schedule.

So what’s the earliest date each year that it can snow in North America?

Actually, that’s a trick question. Snow can fall at any time of the year, including summer, especially at high elevations. For example:

The “S” Word: Snow Falling in Summer?

  • On July 26, 2015, an intense cold front descended on the northern Rockies, bringing several inches of snow to three US states: Montana, Idaho, and Wyoming.
  • August 23, 2015, residents of Calgary, Alberta Canada woke up to a snow covered ground. In fact, many reported on social media that after this incident, they had officially seen snow on the ground during every month of the year in this region.
  • June snowfalls were reported in Hawaii and the Northern Rockies.
  • On July 10th and 11th, snow was reported in parts of Montana, Idaho, and Wyoming. In Yellowstone National Park, there was enough new snow to build a snowman above 10,000 feet!
  • August 18th, snow and sleet hit parts of Montana and Colorado due to a cold front moving in from Canada.
  • Snow coated a few spots in the northern Rockies in early July, illustrating that flakes can fly through the air at any time during the summer months in the mountains in this region.
  • August 27, 2018 – Winter weather advisories were issued by the National Weather Service for parts of the Rockies of Montana and Wyoming; an inch of snow fell at Glacier National Park.
  • June 8, 2019, Montana
  • September 30, 2019, record-setting September snowstorm hit northcentral Montana.

    We had snow often on the 4th of July when I was growing up in Northern Idaho. When Montana/Wyoming were having their road closings, friends were cutting/baling hay in Emmett, Idaho. Not all that far away. It’s time, I am ready!!

    The Memorial Day weekend blizzard of 1982 is local legend in Cleveland.

    Love the snow and winter

  • Cheryl says:

    In the 1970’s, I think it would have been around 77, it snowed in May. I remember that rather distinctly. I lived in south eastern Massachusetts. I don’t recall July snow, but I definitely remember the one in May.

    More recently, on the Vermont/New Hampshire, it snowed Memorial Day weekend. Think it was 2013. The same weekend, my sister living in Alaska, had temps in the upper 80’s-90’s.

  • Linda W says:

    It has already started snowing here in Colorado, up in the mountains in Estes Part the caps are getting a thin layer of snow , and last year it snowed on Mother’s Day .Have a funny feeling this is going to be a bad winter,there’s feel the same way .

  • Theodora says:

    I remember something in my history book about the washing in Boston Massachusetts freezing overnight in mid-July. Though that was due to a nuclear winter, lots of places stay cold year-round. It was 34 degrees (Fahrenheit) in Tionesta, Pennsylvania earlier this July.

  • Snowgirl says:

    I hope it snows in December, january, Feburary too. I like it when glistens on grounds and the cars. I live Virginia it may snow on those or not. I always can hope and dream.

  • Judy Thornberry says:

    The weather has been crazy here in Ky, We have been 20 degrees above what it should be this time of year .Very dry and still a little humid. Be glad to see some rain!

  • weather watcher says:

    The article above says, Farmer’s Almanac predicts the 1st snowfall this season will be in the mountains of Montana in early October. As a matter of fact, they had some snow last week in the mountains of Montana, & it’s only September.

  • Gary says:

    It’s been in the 90’s every day this summer except for one week when it just got to the high 80’s. It’s been humid and the mosquitos and gnats have been extra bothersome. This is South Georgia and it looks like the heat will linger well into the fall. I still DON’T want any snow !! Let the sun shine in !!

  • Jeff says:

    Is it true that it once snowed on the 4th of July? If true what year did it happened?

  • Rain says:

    I need it not to snow until the middle of December. After Ive safely driven across the country & moved.

  • Scarlette says:

    What is “squally weather”? I don’t think I care much for the way it sounds.

  • If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
