Red sky at night, sailor's delight. Red sky in the morning, sailor's take warning.
"This is not crap," says climatologist Kenny Blumenfeld in this week's episode of the Way Over Our Heads podcast with Jim du Bois.
"If you are between the sun and precipitation, you are probably going to see a rainbow and probably a red sky," said Blumenfeld, further explaining the myth. "If you see that (red) at night, that means the clouds are off to your east so much more conducive to clearing weather."
Among the other weather myths that Blumenfeld dubs as correct or nonsense:
- When high clouds and low clouds do not march together, prepare for a blow and a change in weather.
- Wherever you are in the northern hemisphere, if the wind is to your back, then to your left is a low-pressure system and to your right is a high-pressure system.
- If a rainbow appears, it's a sign that the storm is over.
They also look back at the recent cold snap, the prospects for spring flooding and and the potential for stormy weather next week.
