Another frequently quoted one is:
"Ne'er cast a clout till May is out."
I used to think this referred to the month - in which case it is usually correct. However, when I realised it referred to the May / hawthorn tree (referring to the tree's blossom) I am not so sure of its reliability.

A clout is a target. Any bit of litter stuck in a hedge. Such a target in that season would be used for ploughing. In other words, it is never too late to plough if the first hedge bushes are not in flower.

I imagine a farmer can wait for the weather to get the fields ploughed in the most suitable condition.
Hardly a weather lore.
