November prediction

On my TP it’s showing November weather for the days we’ll be at WDW. How do they come up with this prediction???

They take the historic norm and project. For example, it’s a pretty sure bet it will rain sometime during there day during August. :smiley:

That being said, any honest weather person will tell you that forecasts beyond 2-3 days have as much accuracy as flipping a coin. :wink:
