Planning Outlook
Very warm or hot conditions this weekend in the mountains and the valleys, with extreme risk of wildfire in Scotland; beware dehydration and sunburn. Light winds and very little cloud. Low pressure returns late Sunday into Monday bringing rain to most, risk heavy or thunderstorms north England and Scotland. Temperatures will cool towards average and often raining for the first half of the week. Becoming more mixed from mid-week as pressure goes slack and Atlantic fronts make only weak pushes from the west. Patchy rain and cloud will come and go with the best opportunities for sun in north and western areas.
