Planning Outlook
Westerly winds strengthen widely later this week, reaching gale-force over Scottish tops on Friday; low cloud across western Scotland, drizzle and steadier light rain, turning heavier later Friday. A swathe of persistent rain and strong winds moving southwards across Britain into Saturday, leaving a legacy of showers for Scotland, winds tending to lessen. Further areas of showers into Sunday. A changeable westerly pattern into next week and likely into early August, bringing spells of rain and showers; varying wind speeds, strengthening at times to gales on high tops. Often cooler for Scotland, a mix of cooler and warmer days for England & Wales.
