Weather School: Red Sky at Night

In this week's weather school, Meteorologist Michael Page explains if "Red Sky at Night" really is a "sailor's delight."
It's a common saying, "Red Sky at Night, Sailor's Delight." Many have been using it this week with several vivid sunsets. But does the expression hold up scientifically? Sort of.

The vivid reds at sunset are produced by low-angle sunlight moving through particles, like dust, in the air. Those particles remain somewhat suspended in stable weather conditions, supplied by high pressure.

Since the sun sets in the west, that means the stable high pressure sits between the sun and your location. Recall that most of our weather, in the mid-latitudes at least, moves in from the west.

That means high pressure, often associated with nice weather, is moving to your location. Hence, sailor's delight!

So, while not always a perfect indicator of what's to come, the saying does work in many cases locally.
