LITTLE ROCK, Ark. (KTHV) - Although the heat doesn't feel like it, you can tell fall is close since school is back in session and pumpkin products are hitting the shelves.

In today's Science with Sarah, we get an expert preview into the autumn colors we can expect.

The new season is right around the corner, and while most Arkansans wonder what kind of weather is ahead of us, the outlook for the foliage is promising.

Fall colors will be bursting before you know it, but it's summer's weather that is giving foliage a hopeful forecast.

"A cool wet summer means happy trees, and they're really growing a lot this year, lots of leaves, you can kind of see that everything is nice and intently green."

Tamara Walkingstick is an associate professor of forestry, and she says the sufficient rain has been crucial this season.

"We've had a really good growing season for trees and there will be a lot of leaves- that sounds silly-but more leaves mean more colors," said Walkingstick.

"It has to do with the number of hours of night that we have in a 24 hours period. We're already noticing the sun is getting up later and later there's sort of a threshold period, which signals to the plant that it's time," said Walkingstick.

And it's the timing that is everything for really intense colors

"We need a drying out session just a week or two before the trees would ordinarily change color.

The rustic oranges and vibrant reds should start coming alive late September with peak hitting in October.

Also starting in late-September, the weather section on THV11.com will have the foliage update. You'll be able to check daily where the peak colors are blooming around Arkansas.
