Question

Happy Sunday everyone! What is the correct usage of the future tense? (Explanation in comments)

Look at that cloudy sky. It _____ rain today. 🌧️

Answer

We use "...going to" for future plans. In your sentence, it's all about prediction. We don't know exactly when, so I will go for "going to"

Answer

we use going to for predictions (it is going to rain) based on something we can see or measure (cloudy sky).

We use 'will' when we don't have evidence.
