Wild Horses in the Sky

The end of summer has come with changeable weather. One indicator in the sky is mare's tails. They are wispy high altitude cirrus clouds that can be an indication that stormy, windy weather is on the way.

Cirrus clouds are made of water vapor that has formed into ice crystals. They are high clouds, about 8,000 metres (26,000 ft.) above sea level. Varying wind speeds at different altitudes cause the wisps to be pulled out in the characteristic horse tail configuration.

And at sunset, they paint the sky with a wonderful warm strokes. -- Margy
