After a rainy/drizzly day yesterday, the clouds cleared off at nighttime, and Toledo dropped to 36. The high temperture 54 today was a real shocker. Obviously, it's not that uncommon for a temperature of 54 to be in early October, but we avoided the cold temperatures so far, with the warm weather pattern. My general idea is that the really good colors of fall start to occur after a few days/nights when the temperature is cold, but not (much) below freezing. Colors of the trees can get really uncolorful with a hard freeze. I saw that in Colorado twice in 16 years.
