If the green be large and bright in the rainbow, it is a sign of rain. If red be the strongest color, there will be rain and wind together. After a long drought the rainbow is a sign of rain. After much wet weather it indicates fair weather. If it breaks up all at once, there will follow severe and settled weather. If the bow be in the morning, rain will follow; if at noon, slight and heavy rain; if at night, fair weather. The appearance of two or three rainbows indicates fair weather for the present, but settled and heavy rains in a few days.
Evening Rainbow.
If there is a rainbow at eve,
It will rain and leave.
East and West Rainbow.
Rainbow in the east indicates that the following day will be clear. A rainbow in the west is usually followed by more rain the same day.
Rainbow in the Sierras (i. e., in the east) in evening indicates no more rain. (California.)
Fair Weather.
The boding shepherd heaves a sigh,
For see, a rainbow spans the sky.
