Planning Outlook
High pressure, generally centred near northern Britain, will develop toward the weekend, bringing a low rainfall (although here and there thundery showers) and for most mountains areas extensive sunshine and light winds. Nevertheless, cloud will come and go, most widely across more eastern mountains. It will remain very warm but feel slightly less humid than at present.
