I couple of old wives tales that I’ve grown up with:
1, When the wind blows the tree leaves such that they turn over there is a storm aproaching
2, When the cows are laying down in the field it will likely rain. I assume that if half the cows are laying down and half standing there is a 50% chance of rain BUT nobody has officially clearified this point for me.
3, Of courses there is always the ring around the moon that predicts snow but that is more sicience than old wifes tale.
