I leave in 5 days also, and have been tracking the weather for the last month or so. Almost every single day in the last month has called for scattered thunder storms. The weather has actually been good though, according to the several people I know who have been in the last few weeks. They all said it rained a bit almost every day, but nothing major. So the weather says scattered thunder storms, but it's likely that it will barely rain. I don't mind the rain, as it will take the edge off the outrageously hot, humid weather that will be there.
