Additional weather information
Meteorologist's view
Breezy and gusty conditions at times will make for fairly arduous walking on exposed terrain with buffeting of clothing. Balance may be affected at times. Feeling quite warm at glen level.
Weather
Mostly dry in the morning but there may be the odd spot of rain for the island ranges at times. Quite extensive areas of low cloud in the morning with the best of any clear breaks for Mull, Knoydart, and other west coast ranges. Low cloud lifting and breaking through the morning to leave bright or sunny spells in the afternoon but high cloud turning the sunshine quite hazy. Some showery rain will push north, most likely over island ranges and Moidart, heavy at times with a small chance of thunder. Low cloud feeds back into most ranges in the evening.
Chance of cloud-free hill tops
40% or less in morning and evening, best chances northwest. Rising to 75% in afternoon.
Low cloud and visibility
Quite extensive areas of cloud down to 400-600m in the morning and again in the evening. Once this lifts and clears in the morning summits will be mostly clear with good visibilities and the cloud layer above the tops. Visibilities falling moderate or poor as showery rain passes through.
Ground conditions
No recent ground conditions report available.

Weather

Chance of hail and lightning. Warm again in glens.
Chance of cloud-free hill tops
