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

Question

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.

Because for all the high-tech tools we have, weather forecasting remsins an inexact science. In fact, the FAA Airman’s Info Manual (AIM) specifically warns pilots that weather forecasts longer than 6 hours in advance should be considered “unreliable”.
