At sunrise Wednesday, April 10, the sky was bright red in the eastern sky and a pinkish-red sky was overhead as far as one could see. By 6:45 a.m. the red was gone, and by 7:00 snowflakes were falling to the ground.
The common phrase “red sky at morning” is a line from an ancient rhyme often repeated by mariners. The rhyme is a rule of thumb used for weather forecasting during the past two millennia. It is based on the reddish glow of the morning or evening sky, caused by haze or clouds related to storms in the region.
Red sky at night, sailors’ delight.
When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west. Basically good weather will follow.
Red sky at morning, sailors take warning
A red sunrise can mean that a high pressure system (good weather) has already passed, thus indicating that a storm system (low pressure) may be moving to the east. A morning sky that is a deep, fiery red can indicate that there is high water content in the atmosphere. So, rain could be on its way.
The concept of “Red sky at night, shepherd’s delight. Red sky in the morning, shepherd’s warning” first appears in the Bible in the book of Matthew. It is an old weather saying often used at sunrise and sunset to signify the changing sky and originally known to help the shepherds prepare for the next day’s weather.
Despite there being global variations in this saying such as “Red sky at night, sailors delight. Red sky in morning, sailors warning,” the scientific understanding behind such occurrences remain the same.
