The skies clear up after a rainy morning. Our skies are a paler blue because of our high humidity that often reaches saturation point. It usually feels terribly stuffy before it rains. Rains bring with it such sweet relief and for a while the air is cool.
Cumulus clouds form on a blazing hot day, as the hot air rises and condenses. It usually means there will be conventional rain later.
I love how the sky is tinged with a lovely pink with the sunset at dusk.
