Accuweather is charging to see % chance of precipitation now? Really?
Ahem...
While I'm not a Floridian, it also helps to learn what those percentages mean, along with the description of the weather itself.
The percentages are a guess based on history. When the atmosphere was similar to how they're thinking it's going to be that day, it rained x% of the time over the past y times. It does NOT mean that it's going to rain x% of the day! It also does not mean that the entire forecast area will see rain, which leads to part 2...
Isolated, Scattered, etc. These are typically used for Thunderstorms or showers, and signify how densely packed the storms will be. I don't know if there's an actual standard for this, but my typical description is:
Isolated - It can be storming in DHS and sunny(ish) in Epcot.
Scattered - It can be storming in DHS and Epcot, and sunny in MK.
Note that even if a small storm passed through off of WDW property, it would "qualify" for that % chance of whatever, and thus marking it as "had rained" under those conditions into the data.
(I'm sure it's all a bit more complex than that, but that's my understanding of the basics).
Besides, FL weather is notoriously volatile. It can go from bright and clear, to downpouring, back to bright and clear in the span of 30 minutes.
