Tuesday 16th August Weather forecast for the Western Isles.

Good evening Western Isles on this Monday evening we are seeing a mixture of clear skies and cloud. Winds under 20 mph and today’s high of 15.2C

Mist and low cloud once again caused issues with ferry delays and cancellations today along with Plane delays and cancellations. This is one of the worst summers I can remember for Mist and Fog we always get spells of it during the summer months but I don’t remember it being this frequent.

Tuesday

For Tuesday high pressure starts to build in behind the cold front that is slowly moving across from the West Coast of Scotland. As shown by the Met Office chart below.

Overnight – Some rain and drizzle with some mist and low cloud. Increasing amounts of clear skies. Winds of 10 to 30 mph.

Morning and afternoon – Some lingering mist and fog should clear away. Increasing sunshine with some scattered heavy showers. Some decent and prolonged afternoon sunshine. Winds of 10 to 30 mph.

Evening – Most of the showers will clear away a few well scattered showers in places. For most a fine and dry end to the day with variable amounts of cloud and decent and prolonged sunshine. Winds of 10 to

30 mph.
