Planning Outlook
Settled summer weather continues into the weekend and next week as high pressure dominates. Warm temperatures on the hills in midweek will trend cooler from the north from Friday into the weekend, dropping below 10C on summits for periods, mainly Scottish mountains. Most persistently cooler in the north where some cloud will be drawn onto high terrain and over tops at times, occasional light showery rain; occasional inversion conditions in the morning. Otherwise generally ongoing dry weather, with good amounts of sun and many hill tops often clear of cloud. Continuing very high risk of fire with extremely dry ground conditions. A change of weather pattern late in the month brings scope for rain and thundery showers.
