Using frog croaks to predict the weather

In 1975, Chinese meteorologist Chang Chi-tsai came out with "Chang's law" which codified the relationship between croaking frogs and the weather:

If frogs croak on a fine day it will rain in two days.
If frogs croak after rain it will be fine weather.
It will continue to rain if frogs do not croak after successive overcast days.

Previously we've posted about how to use gnats to predict the weather.

If string wet, rainy weather.
If string white, snowy weather.
If string horizontal, stormy weather.
