By MATT PIKEIt’s officially the first day of autumn. Leaves on the trees will begin changing, and the Missouri Department of Conservation is predicting a promising season of fall colors in the northwest region of the state. In fact, Forester Timothy Wolfe says some leaves have already begun to change. Wolfe says by the end of October it will be past the peak season of colors and things will start browning out after that, depending on the different variations of tree. The Missouri Department of Conservation also offers reports on its website to the conditions where some of the best fall colors are around the state.
