Additional weather information
Meteorologist's view
Quite a cool feel with fresh or strong northerly winds at height.
Weather
Through the morning it will remain cloudy but mostly dry except in the east, the best conditions will be found in the west and Arran and some brighter spells here. Generally brighter in the afternoon but with the chance of the odd sharp shower. Brisk east backing northeast winds will add to a cool feel to the day.
Chance of cloud-free hill tops
In the east 60%, further west 90%.
Low cloud and visibility
Scattered cloud layers above 500m in the east of the area at first in the morning, cloud will be patchier with higher bases further west of the area, with just a few patches around western coastal ranges and Arran. Cloud will slowly lift in the east. Visibility will generally be good or very good.
Ground conditions
No recent ground conditions report available.
Mountain weather information
Weather
A dry start on Saturday and perhaps bright or even sunny for a lot of the ranges, perhaps some mist and fog in sheltered valleys. Clouding over from the west during the morning with some showery rain in the Trossachs in the afternoon, showers may become slow moving and torrential for a time in the west later in the day.
Chance of cloud-free hill tops
70% improving to 90%

Patchy low cloud around northern summits in the morning will clear to leave most summits clear of cloud through the afternoon.
