ROBINSON, Ill. (WTHI) - Kevin Orpurt traveled to Robinson, Ill. for this segment of Hey Kevin!

Stephen Miller wanted to know…

“Hey Kevin! Do the jet contrails we see in the sky have anything to do with forecasting the weather?”

The answer is yes.

A jet contrail is actually the trail of a jet as it flies through the sky, one of the by products of burning jet fuel is water vapor.

And so high in the sky, if there's already a lot of water of vapor in the sky, or if it's quite cold in the sky, it leaves a trail.

The more moisture there is in the sky, the longer the trail will be.

If there's more moisture in the atmosphere, that's often a very good indication that there's rain on the way.

So, a jet trail that's very long in the sky is often a good indicator of rain because there is more moisture in the sky.

More moisture in the sky means there's a better chance for rain on the way.
