Planning Outlook

High pressure slowly retreats over the weekend to allow west-southwesterly winds to move into Scotland, bringing more cloud to the northwest and some drizzle on Saturday, though most places remain dry. By Sunday, stronger westerly winds and a front passing eastwards with a spell of rain followed by lowering temperatures and showers with snow and hail over the hills in Scotland. A chilly start to the new week, near or below freezing over higher mountains, particularly Scotland. Changeable westerlies during next week, windy for all at times, showery conditions most common in western Scotland. High pressure to the south rebuilds at times to settle things again.
