If it is red at night, the following day will have good weather. The scientific explanation is that this is an approximate guide. Two factors contribute to the cogency of this saying. The first is that weather systems generally travel from west to east in the mid latitudes. Because the sun rises in the east and sets in the west, a rising sun in advance of an approaching weather system would illuminate the approaching mid- and high-level clouds to create a red sky in the morning. Alternatively, if the sun is setting as a weather system exits and high pressure is building, then the departing clouds would be illuminated. This would create a red sky at night with fair weather to follow. The reddish color results from scattering of sunlight by suspended particles and aerosols in the atmosphere. The suns rays pass
