If you play it right and don't mind moving around a little you an stay just over 3 months free in Missouri. I'm thinking Spring after spending the winter in Arizona or maybe Fall just before you go to Arizona. I live in Missouri so I wouldn't recommend spending a Summer there unless heat and humidity is your friend.
