When high clouds are seen crossing the sun or the moon in a different
direction from the lower clouds, this indicates change of wind toward
the direction of the higher clouds. When you see hard-edged clouds, look
for wind. When you see delicate soft clouds, look for fine weather and
probably moderate breeze or high breeze. When you see gloomy dark clouds
in a blue sky, look for slight winds. When you see a bright blue sky
through fine clouds that are soft and delicate, this indicates fine
weather. When you see soft-looking clouds, you can expect less wind, but
probably rain. But when the clouds become hard and ragged, tufted and
rolling in appearance, stronger winds are coming. When you see small
clouds that are inky looking, look for rain. When you see light clouds
traveling across heavy hard masses of clouds, this indicates both wind
and rain, but if the light scud clouds are alone, you may expect wind
only. Misty clouds forming or hanging over the peaks of hills indicate
both wind and rain. If during a rainy spell they ascend or disperse the
weather is pretty certain to clear up. If there has been fine weather
and you begin to see light streaks in the sky which are distant clouds,
and they continue to increase and grow into cloudiness, this indicates
rain.
