When halo rings the moon or sun Rain's approaching on the run. When the ass begins to bray, be sure we shall have rain that day. When leaves show their back, rain we won't lack. A test report. Cows lying down, good indication of rain.
Flowers smell best just before the rain.
Bees do not swarm before a storm. If a rainshower produces bubbles in puddles, there will be rain the following day. Forecasting snow, all from the northern hemisphere. Snow like meal, snow a great deal. A test report.
