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 with outbreaks of rain, especially for the Southern Cairngorms and Angus Glens, the best conditions will be found west of the A9 and probably towards Loch Tay and Glen Lyon with some brighter spells here. Brisk northeasterly winds will add to a cool feel to the day.
Chance of cloud-free hill tops
In the east 30%, further west 50%.
Low cloud and visibility
Layers of overcast cloud above 300m in the north and east of the area at first in the morning, cloud more broken and perhaps with higher bases further south and west in the area. Cloud will slowly lift and some breaks will develop in the afternoon west of the A9 but the Aberdeenshire tops will likely be in cloud most of the day. Visibility below the low cloud will be moderate or good but further north and east it may turn poor in heavier rain or drizzle for a time.
Ground conditions
No recent ground conditions report available.
