Red sky

Red sky at night, sailors delight. Red sky in the morning, sailors warning. Is this old addage true?

Storm systems generally move in from the west. A red sky at night, indicates high pressure and stable air coming in from the west. The red sky is a reflection of the high concentration of dust particles. In layman's term, good weather will follow.

However, a red sunrise indicates that a storm system may be moving to the east. This is because a red sunrise is a reflection of the dust particles of a system that has just passed from the west. A deep fiery red morning sky often means there is a high concentration of water in the atmosphere, ie. rain is on its way.

Sailor expressions are the best, and always have some truth. Interesting how they infiltrate the language.

Oh, very interesting. I'm sitting here now trying to remember from which direction I usually see clouds roll in. Hmmm...

Nice shot by the way. :-)
