Hill fog will lead to navigational difficulties especially during the afternoon as cloud lowers and becomes more extensive. Winds will also strengthen during the afternoon with a risk of gales on the highest tops during the afternoon.

The morning will be dry but low cloud will spread east across southern Lochaber and much of Argyll. The afternoon will be overcast with rain gradually spreading southeast, but Arran and the Trossachs will stay dry until early evening.
Chance of cloud-free hill tops
50%, best across Arran and the Trossachs
Low cloud and visibility
Becoming poor in hill fog down to 700 metres across Mull, southern Lochaber and Argyll through the morning after a clear start, but clear elsewhere. Then low cloud gradually spreading to the rest of the area through the afternoon with bases down to 400 to 700 metres, lowest bases across southern Lochaber and northern Argyll.
