I'm from SF Bay Area but lived in Alabama for 3 yrs (not far from Tennessee). It rains the most in the summer in the Southern USA, much like the tropics. Very humid with lightning storms and rain drops as big as a house. It usually comes and goes quickly though so it's not raining all day long in the summer usually. To demonstrate how humidity works, I was very surprised to observe my first week there that it rained super hard with inches of rain pooling on some nearby tennis courts and when I went inside for class there was at least a good inch of standing water there. When I got out of class 90 min later, the rain had stopped AND the courts were BONE DRY. If that happened here in California, the rain would take days to dry out. Over in the south I couldn't believe how the humid air could absorb all of that water like a sponge.
KD, I created an FBBO thread a few years ago on how many months out of the year do you drive you mopar? Here in California, most of us could drive them 9-10 months a year if we wanted to due to the temperate climate. Some responders said they can only drive 3 months out of the year due to ice and snow, etc. Man, that is hobby dedication for those mopar owners! We're really spoiled here for driving. I would imagine in Tennessee if you want to avoid rain you could still drive 6-9 + months out of the year, but much of it likely would not be consecutive.
