Florida forecasts change daily. You could check it one morning, then check it again that night and its something entirely different. I suggest to stop worrying, and just check the forecast a day or two before your trip and take it with a grain of salt. We leave on Monday(Sept 28th). I cant tell you how many times the forecast for my trip has changed. As for the above post, there is a Atlantic storm that will be traveling up the coast, bringing some rain. However that is most likely to be sometime between Wed-Friday this week, and will have a greater impact on North Carolina and Georgia than Florida. I've gone down to Florida a lot, as my dad use to live down there. If you notice, weather.com tends to always leave a 50-60% chance of rain and thunderstorms throughout their 7-10 day forecasts. Always have been that way. Also sometimes Accuweather tends to give a more accurate forecast than weather.com. Take today for example, weather.com forecast that Orlando would be overcast today, while Accuweather forecast it would be "more sun than clouds". My brother is down there right now, and he said its really sunny and nice down there today. So long story short, you could spend hours on end, worrying about the weather for your trip. But it's pointless. My trip is in 5 days, and I expect the forecast to change a million more times before I go.
