Planning Outlook

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.
