Weather Signs The moon to appear very clear and straight is a good sign of the weather. The mountains to seem very far away is another good sign. If the roads keep wet a good while after rain it is a good sign of the weather. To hear the weir at Ardfinnan roaring is a sign of frost and to hear the weir at Castlegrace roaring is a sign of rain. To hear the glens in the mountains roaring is a sign of storm. When the crows are flying around in circles is a sign of rain. When the cattle are to be seen lying on their right side is a sign of rain. When the frogs are croaking in the ponds is a sign of rain. A ring around the moon is the sign of bad weather. When cobwebs are to be seen in the grass is a sign of rain.Brian Phelan
