Summer ice on the Great Lakes – No big deal

Summer ice on the Great Lakes – No big deal

It also happened a few years back.

Above the black line, the area was covered with ice.
Below the line, people could have survived.

  1. There was a snowfall in international falls during a 4th of July parade not that long ago that locals talk about but I can’t find anything to back it up what I found was the NWS in Duluth denying this and saying Minnesota’s latest official snowfall is June 4th but the locals out here swear up and down it happened…anyone can help me dig this up would be appreciated

    • I’m hundreds of miles south of Int. Falls in WI. I’ve heard the “my gramma told me about snow on the fourth of July when I was little.” That is the back in my day crowd claiming things that never happened, claiming things that happened somewhere else as that locations conditions, screwing up dates and months, or greatly exaggerating actual events.

  2. Good one, Robert! I followed the cold winter and Great Lakes Ice closely this winter, and it was a HUGE deal – but totally minimized and obfuscated in the mainstream media. I am a Quaternary Geologist, and grew up on Lake Michigan, so of course I appreciate your ice age extent map!

  3. Thank you, that made my day! On a more sober note, the day may be at hand that the solid line reforms.

      Bring it on!

  4. Snow in June in Nunavut.

    Snowfall warning in effect for:

    Clyde River

    Snowfall – late evening Wednesday to late evening Thursday.

    Snowfall, with total amounts of 15 to 25 cm (5.9″ to 9.8″) is expected.

    A low pressure system over central Quebec will track northward and deepen over the next 24 hours. Rain will spread into southern Baffin Island this morning with 15 to 25 mm (.59″ to .98″) of rain expected for southern areas of the island. As this system tracks northward into a colder airmass the rain will change to wet snow. Heavy wet snow is possible over central portions of the island this evening into Thursday with the heaviest amounts expected in the Clyde River area with 15 to 20 cm (5.9″ to 7.9″) of snow expected by the time the wet snow tapers off Thursday evening. Locally higher amounts of up to 25 cm (9.8″) are possible over higher terrain.

    Visibility may be suddenly reduced at times in heavy snow.

    Environment Canada meteorologists will update alerts as required. Please continue to monitor your local media or Weatheradio for further updates. If you would like to report severe weather, you can call 1-800-239-0484 or send an email to or tweet reports to #NUStorm.
