Here are some sayings I can think of...
- Red sky at night shepherd's delight, red sky in the morning shepherd's warning.
(some people say sailor instead of shepherd)
- The north wind will blow and we shall have snow.
I have a hunch that that's a line from a longer saying)
- Ne'er cast a clout 'till May be out.
(There's a big debate about what this actually refers to... but basically it means, wrap up warm until the end of May/or until the May blossom is out)
- Raining cats and dogs.
- One swallow doesn't make a summer.
- March comes in like a lion and out like a lamb.
- March winds and April showers bring forth May flowers.
I didn't know I knew so many!
I'm not getting so much inspiration from song titles though...
Hope that helps,
Helga
