Weather Too Bad?

Hey folks,

We are in the Florida keys for a week, and we have Tuesday and Thursday open to go check out the Everglades. Unfortunately, it seems like thunderstorms are predicted both of those days. For anybody familiar with the area and weather patterns, could we still have a good trip during this bad weather? Will it blow out, or likely sit for a while? The only activity we had picked out was a bike rental, so any other suggestions would be welcome.

Thanks!
