Good evening Western Isles we are seeing the rain and cloud slowly clear away from the islands. Some mist and low cloud lingers. Winds under 20 mph and today’s high of 18.5C

The Western Isles missed out on the heaviest rainfall today as shown on this chart. It was wet for Barra and Vatersay. For me, on Tiree, it was a very wet day.
