jb,
For the central states our tornado/flood season is generally towards Spring, the April, May, June time frame varying year to year - this year has been quite wet and extended some. That said, storms creating tornado's can crop up into the summer, too, but are less frequent as everything evens out in temperature. As for the temperatures, we are 180 degrees out of phase with your norm, so the weeks after October will be getting cooler, heading into Fall, then Winter. You've picked an ideal time to travel across middle America. The extreme heat of July & August should be gone, transitioning into cool nights and wonderfully warm days. I expect that we can keep the alcohol level moderated to an acceptable level. ;):):):)
