I took this photo at 9 pm last night and remembered the rhymes:
In Great Britain and Ireland:
"Red sky at night, shepherd's delight.
Red sky in the morning, shepherd's warning."
There's a slightly different version in North America:
"Red sky in the morning, sailors take warning.
Red sky at night, sailor's delight."
I don't now about the shepherds, but I was delighted this morning! We should have some very nice weather all this week...
