CHICAGO (WBBM NEWSRADIO) -- Our gray, rainy days could lead to an explosion of color in the fall.  

Heavy rain only affects fall colors if the rain falls in late September or early October, said Ed Hedborn, plant records manager at the Morton Arboretum in Lisle.

But he said the ground has soaked up plenty of moisture during the rainy periods in August and September, and that should help produce a good show.

"That sets plants up to have good color," he said.

But, the rest of the climate has to cooperate.

"The temperature of the day, the temperature at night, and in some respects, how hot it gets during the day and how windy," he said.

We're still a few weeks away from the start of fall colors, he said.  Fall colors are triggered by shorter days and longer nights.   

The official start to fall is Sept. 22.
