Additional weather information
Meteorologist's view
Unpleasant conditions at first and feeling bitterly cold with showers and widespread strong winds giving difficult walking conditions with a risk of being blown off balance, whilst navigation could be challenging with energy output significantly increased when walking into the wind. Much better conditions in the afternoon but still quite chilly.
Weather
Scattered showers mostly over western ranges such as Perthshire Hills, Ben Vorlich and Ben Vrackie in the early morning, heavy at times, staying largely dry in the sheltered east towards Aberdeenshire Hills. Also in the early morning there will be gales with a chance of storm-force gusts over the highest summits. Showers and strong winds gradually easing for all ranges after dawn, becoming largely dry in the afternoon with good sunny spells. Some high level cloud spilling east later in the day.
Chance of cloud-free hill tops
At first 30% west of A9, 70% east. Rising to 75% or higher for all by afternoon.
Low cloud and visibility
Cloud becoming quite widespread down to 800-1000m in the morning and visibilities falling moderate or poor as showers pass through with some clearer spells in-between. In the afternoon and evening cloud will generally be above summits with some good clear spells developing but still the odd patch of cloud around 900-1100m possible.
Ground conditions
No recent ground conditions report available.
