Why are weather forecasts sometimes so different from each other? Don’t they all use the same data and science?

I’m talking about information displayed on different weather websites. One will say that there’s a very high chance of rain in a place at a certain hour, for multiple hours, and another will say that there will be just some light rain in the first hour, then it will be dry/sunny.

Chaos theory: sensitive dependence upon initial conditions.

Or, to explain it like one is five, if you look outside, you can easily predict what the weather will be like in 3 minutes. You are less likely to be able to know what the weather will be like in 3 hours, and by the time 3 days will have gone by, the number of potential variables and changes in the environment between your prediction and that time approaches infinity, so prediction becomes much closer to impossible.
