LITTLE ROCK, Ark. (KTHV) - Storms are once again in the forecast this weekend, and in this week's Science with Sarah, she is explaining how to decipher the difference in straight line wind and tornado damage.

The last round of storms had the threat of tornado but turns out, there were only thunderstorms.

We learned looking at the damage afterwards, thunderstorms winds can be devastating too.

So, what's the difference?

Classifying the difference between thunderstorm and tornado damage is more than what meets the eye.

John Robinson coordinates the warnings from the National Weather Service.

He's half of the 2-person team that goes out to rummage through the aftermath.

"The first thing we do is decide where to go, if there are injuries or if someone's been killed we'll go there first," said Robinson.

Contrary to what we may think, investigating storm damage can take days or weeks.

"We're going to look at the entire damage scene, and that might be a small area of 10-15 miles long," said Robinson.

Investigating tree damage along with eye witness accounts is key to confirming storm reports.

"Typically we'll look at how debris fell. This last episode, to us, all the trees fell in the same direction," said Robinson.

Which always means the damage is from straight lined wind, but what about tornado damage?

"You're always going to have some trees out of place no matter what- but what we're looking for are groups of trees that are grossly different than the others," said Robinson.
