Very warm; sun weakened by high cloud, some haze
Variable 10mph or less for several morning hours, trending north-northeasterly and strengthening to 10-15mph afternoon, often gusting 20mph or stronger over the tops.

Settled summer weather continues through the weekend and next week as high pressure dominates. Extremely dry ground conditions persist with a high risk of wildfire. Temperatures will trend cooler, dropping below 10C on summits overnight in Scotland, but afternoon temperatures rising to warm or very warm; most persistently cooler in the far north where some cloud will be drawn onto high terrain and over tops at times with occasional light showery rain; high summits of the Scottish Highlands sometimes above a morning cloud inversion. Otherwise generally ongoing dry weather, with good amounts of sun and hill tops often clear of cloud. A change of weather pattern indicated late in the month brings scope for rain and thundery showers.
