Planning Outlook

High pressure will be in charge for the next week to 10 days or perhaps longer, bringing extensive fair weather. This weekend sees a little patchy rain and low cloud for the north-western Highlands brought in on fresh westerly winds, otherwise it will be dry with summits generally clear. Temperatures rising next week, becoming widely hot and humid. A possibility of thunderstorms developing by the end of June, but very uncertain - a chance that they do not develop at all.
