WEATHER FOLKLORE: "Evening red and morning grey, two sure signs of one fine day" APPLICABILITY: Midlatitude locations. ANALYSIS AND INTERPRETATION: The weather tends to move from the west toward the east in the mid-latitudes. A red sky in the evening often means the setting sun in the western sky is shining on clouds in the eastern part of the sky. Precipitation in the east will often move away since weather tends to move east. A morning grey sky as the sun rises in the east means the precipitation is already to the east of the area and will thus not move into the area. PITFALLS: Precipitation regions do not always move west to east. Also, clouds are not always associated with approaching or exiting storm systems. |
