The morning glow at breakfast indicates that the weather is possible.

Morning glow means it will turn cloudy or have light rain.

Beautiful morning glow and sunset glow sometimes appear in the sky. This is because sunlight is scattered on clouds containing many small water droplets. Under normal circumstances, the morning glow indicates that it will rain during the day; The sunset glow indicates that it will be sunny the next day. Therefore, there is a proverb "Don't go out at sunrise, but go to Wan Li Road at sunset".

Extended data:

The color of the morning glow is the reason why it is red.

Colorful clouds often appear on the horizon around sunrise and sunset in the morning and evening. The morning glow and sunset glow are caused by the scattering of light by air. When sunlight enters the atmosphere, it will scatter when it meets atmospheric molecules and particles suspended in the atmosphere.

These atmospheric molecules and particles themselves do not emit light, but because they scatter sunlight, each atmospheric molecule forms a scattered light source. According to Rayleigh scattering law, light with shorter wavelength such as violet, blue and cyan in the solar spectrum is most easily scattered, while light with longer wavelength such as red, orange and yellow has stronger light transmission ability.

So we see that the clear sky is always blue, while the light above the horizon is only yellow, orange and red with longer wavelengths. After these rays are scattered by impurities such as air molecules and water vapor, the sky there will be colorful.
