What will the weather be like?

A common question people have is "What is the weather like when I'll be at Disney World?" If you are close to your trip you can get 15 day forcasts from Accuweather.com or a 10 day forcast from The Weather Channel. However, if your trip is months away what do you do? My solution is to go to WeatherUnderground.com and look at their historical weather section. For instance, if you want to see historical high/lows, rainfall, wind for May go here. You can change the month or view by week/day. This is the most useful tool that I have found for planning long range. As they say in the stock market, "Past performance is not an indicator of future performance." However, with weather you can get a pretty good idea of what to expect if you know the highs/lows and averages.
