Can't read a word of Japanese, or should I say a character, but I believe the weather buttons allow you to see how the different weather conditions will change the crowd forecasts. In other words, hit the umbrella one, and it will show you what the projected forecast is if it happens to rain that day. The windy one appears to have the greatest effect. Surprisingly, even more that the cold/snow.
Forget 'Great Moments With Mr. Lincoln,' Samantha Brown is Disney's most sophisticated animatronic. ________________________________________

The weather buttons are amazing. Overcast days are the most crowded, followed in descending order by sunny days, rainy days, and typhoon days. Typhoon days are the best--the parks are virtually empty and everything is a walk on. I'm amazed that people sit on Big Thunder Mountain in the rain and get soaked.

Forgot to mention: one of the best crowd indicators are the Disney Vacation Club point charts. Higher points for a room mean bigger crowds; lower points for a room mean small crowds. Look for value season and you'll know when the best time to visit is.
