Planning Outlook

High pressure weakens as the weekend approaches: varied low cloud and valley fog remain likely in the mornings, causing damp surfaces and slippery rock-faces. Cloud lifts higher during the day, starting to shroud mountain peaks more often, cooler temperatures returning to the high tops. Local cloud breaks, best of breaks in west Wales, though a haze will linger on low slopes of southern Scotland, England, and Wales - clearer air likely below the cloud in the Scottish Highlands. Light winds overall, an easterly breeze for Wales. The weekend sees a transition to low pressure. Winds will rise and more high cloud will reduce sunshine, rain then arriving late weekend and coming and going into the next week. Timing and location of rain uncertain for now.
