Weekend Warm-Up And More Weather Phenomena

Happy Friday. We actually made it to the 20s today. This was the beginning of the warm-up that will last about a week. Temperatures will make it to the 30s on Saturday and we might actually touch 40 late next week. If we did not have such an extensive snow pack, our temperatures next week would likely be in the fifties. However, take a look at all the snow.

Look at how much of the country was covered with snow this morning. Snow was in every state but Florida. Over 63% of the United States was covered in snow. That is about to change. The snow in the Plains states will quickly disappear as temperatures soar into the 60s early next week. After Nowata, Oklahoma dropped to -31 degrees yesterday, an all-time state record for cold, the temperature swing will be 100 degrees in less than a week as they warm to 70 by Wednesday.

Earlier this week I talked about ice balls and ice canoes. Certainly interesting weather phenomena. Today, I received an email from a viewer asking about a loud thunder-like noise he heard on Tuesday night. He asked if it might have been a “cryoseism”? I had no idea because I had never heard that term before. A “cryoseism” is an ice quake. It occurs in extremely cold weather or when there is a sudden temperature drop. It is similar to an earthquake on a very small-scale. It usually happens when water freezes in the sub-soil and expands. This can cause a very loud sound and actually shakes the ground. I am not sure if it was a cryoseism on Tuesday night, but numerous cryoseisms have occurred in our area before. It happened in Madison in 2008 and in New Berlin in February of 1994. Each time a loud cracking sound was heard and the earth shook.

If any of you have ever experienced this, let us know by responding at the bottom of the blog. Thanks.

So this concludes my winter weather phenomena write-ups. I hope you enjoyed learning along with me.

  1. Re Cryoseisms

    They were something I learned about when I was the “earthquake guy” at UW-Milwaukee and had to try to explain apparent earthquakes that happened in extremely cold weather. We did a research project on “ice quakes” in the 70s on the frozen Green Bay. These are fairly common to any ice fisherman who stays out on the ice overnight, hearing and feeling them in the early morning.

    Now in Florida.

    • Thanks for the note, Ron. Your name came up often when I was googling cryoseisms. I see you got tired of all the ice and snow. Thanks for reading the blog.
