Al-Musnad: Predicting rain is the hardest.

Former Qassim University climate professor Dr. Abdullah Al-Musnad emphasized that the accuracy of weather forecasts depends on the length of the forecast period, explaining that short-term forecasts are more accurate, while confidence decreases the longer the forecast period.

Al-Masnad explained via his account on the "X" platform that rain is the most difficult element to predict, as the formation of rain clouds depends on extremely delicate balances between temperature, humidity, air lift, and the movement of air masses. These are local factors that are difficult to model with complete accuracy, unlike other elements such as temperature, pressure, wind, and relative humidity, which can be represented numerically with a higher degree of accuracy.

He added, "Do not trust weather forecasts 100%, because rain is in God's hands alone," citing the Almighty's saying: {Indeed, God has knowledge of the Hour, and He sends down the rain.}

He explained that science offers a calculated probability based on numerical models and scientific analysis, while the true decision regarding rain is an infallible divine decree.
