Planning Outlook
Westerly winds prevail in the extended outlook, though the weather will be changeable. Heavy rain and strong wind is expected Saturday night and Monday, though detail remains uncertain currently. High pressure will bring a brief settled spell around midweek with a mix of cloud and sun, then occasional low pressure systems come and go - western mountains often shrouded in cloud with periods of rain, at times heavy. Some cloud and rain drifts east, mostly in Scotland. Variable winds too, at times quite blustery. Temperatures near average, variably cooler north. Ridges of higher pressure will build occasionally from the southwest for better windows of weather, particularly England & Wales.
