North and south the sign of drought,
East and west the sign of blast.
Tints.
Light, delicate, quiet tints or colors, with soft, undefined forms of clouds indicate and accompany fair weather; but unusual or gaudy hues, with hard definitely outlined clouds, foretell rain, and probably stormy weather.
Thin Light Clouds.
If there be a light-blue sky with thin, light, flying clouds, whilst the wind goes to the south, without much increase in force, or a dirty blue sky when no clouds are to be seen, expect storm.
Tails or Feathers.
If there be long points, tails, or feathers hanging from thunder or rain clouds, five or six or more degrees above the horizon, with little wind in summer, thunder may be expected, but storm will be of short duration.
Two Currents.
Two currents of clouds indicate approaching rain, and in summer thunder.
