South to south-easterly 25 to 40mph, perhaps touching 50mph at times over Cairngorm Plateau.
Walking very likely arduous for periods with a very gusty and turbulent airflow. Significant wind chill and buffeting.
Mostly dry
Very likely staying dry, with just scope for the odd spot of light rain or drizzle for hills near and west of the A9.
Breaks in north, covering hills in south.
Banks of low cloud covering the Drumochter hills and over to Ben Alder across upper slopes above 700m. Further north, caps of cloud mainly over tops.
30% south, 60% north
Little or no sun Visibility good, but poor in any rain or drizzle. General haze west coast.

South-southwesterly winds widely remain gale force over the mountains later this week and through into Saturday, severe upland gales for periods. Showery on Friday, most frequent in western Scotland with hail, also snow over tops. Another belt of persistent rain likely arrives onto western hills into Saturday, snow only highest Scottish tops. A switch to east-southeasterly winds by Sunday into early next week, some residual rain and high-level snow, but a drier theme develops and favouring chillier conditions into the Christmas period.
