The red color is due to some dust being pushed ahead of a low pressure front bringing moisture. The sky has also been used as a weather predictor for thousands of years. A red sky at sunset usually indicates dry weather because the sun is shining through some dust particles being pushed ahead by a high pressure system bringing in dry air. On the other hand, red sky in the morning usually means moisture is on the way. Once again, the sky is red because of the dust particles being pushed on out, but this time by an approaching low pressure system bringing in moisture.
Clouds are accurate weather predictors.
Each type of cloud is caused by specific actions in nature building up to a type of weather. Light, scattered clouds alone in a clear sky usually mean strong winds. But if the sky is clear blue to the West, and clouds dot the afternoon sky, it means fair weather is in store. A rainbow in the morning, is the shepherd s warning. A rainbow at night is the shepherd s delight.
