Planning Outlook

Improving on Sunday as gale-force winds on Scottish mountains gradually lessen and showers become fewer. Warm and humid into early next week, on Monday extensive low cloud and drizzly rain particularly in the west. High pressure to the south will generally dominate the extended outlook particularly for England & Wales with more often drier and warmer conditions through late September into early October. Fine weather likely extends across Scotland for periods too, but a more changeable autumnal mix may continue especially further northwest with rain and stronger winds at times.
