You just have to pick a time and deal with what comes, more or less. As I've written recently, winter is probably not the best time, because of the temperatures, the park facilities are closed and the possibility of snow and ice are too variable.
For the rest of the year, you'll generally have rideable temperatures (there are a few days where heat stroke can become a risk). But you have to be aware and careful, as for any longer distance ride. That means making sure you get enough water and food each hour.
For the risk of rain/thunderstorms/tornados, all you need to do is just be aware. Carry a radio or whatever that can tell you what the pending weather is going to be - if there's talk of storm or tornado watches for the county you are riding in, be careful. If there is talk of warnings, seek some suitable shelter.
As with any endeavor, if you're careful about handling the risks properly, it will go well.
