A Change in the Weather

 ..... So what's new, this is the UK after all! 
 
Spectacular Mare's Tails over the Dysinni and Fathew valleys this morning, advance notice of tomorrow's rain.

From the web:
Cirrus clouds consist almost exclusively of ice crystals that appear on the sky in white delicate patches or narrow bands. Most cirrus clouds are semi-transparent because the ice particles are very small and low in number. The common English name for a cirrus cloud is Mare's Tails since the long threads of cloud often resemble a horse's tail. Cirrus clouds are sometimes a sign that wet and stormy weather might be coming.
