If the ashes turn blue it's a sign of rain
If the smoke goes up straight from the chimney in the morning that day will rain.
If the smoke goes up straight from the chimney in the evening it's a sign of good weather.
If the dog eats grass we shall have rain.
If the cat scrapes a piece of timber, it's a sign of rain, and whatever side he is turned to when he is scraping that is the side the storm will come from.
If the soot falls we shall have rain.
If the blackbird comes picking near the doorstep we shall soon have snow.
