Growing up on the farm, my Grandpa had quite a few weather sayings - some legit, some not so much.

For example, he claimed that once the cicadas started making noise, 90 days later we could expect our first frost - and by golly, often times he was right.

In fact, over the years, a lot of his "weather wisdom" has been confirmed by various studies done at the college and university level.

Todd Heitkamp of the Sioux Falls National Weather Service has been on the air with me numerous times over the years explaining how often times there actually is some scientific validity to many of these "old farm sayings."

Here are a couple of my favorites when we used to take the kids camping:

  • To estimate the temperature outdoors in degrees Fahrenheit, count the number of times a cricket chirps in 15 seconds and add 37.
  • To gauge how many miles you are from a thunderstorm, as soon as you see lightning, count the seconds until you hear thunder, then divide the total by five.

Don't laugh - it really works.  Give it a try sometime, you'll be amazed!
