Horses tails and summer days

      Finally we have some light but steady rain after the power cut inducing thunderstorm earlier in the week but during the previous ten days we've had some stunning blue skies.
      High, very high up, the jet stream was spreading the ice crystals of the cirrus fibratus into the typical trade mark horses tails and then the clouds were changing in to what look like frown lines just above the tree line. We're not sure which cirrus it is but it's one of them, we think.
       While the jet stream does the work we're just sitting here watching the changes in the sky enjoying a cup of coffee.
