Planning Outlook
Dropping colder across the Highlands by Thursday, near to freezing on higher summits; strong westerly winds in the north giving considerable chill factor and bringing a few showers. Warmer further south - risk of local thundery rain for Wales later Thursday. High pressure centred toward the northwest maintains plenty of dry weather over the Bank Holiday weekend with broken cloud and sun; brief local showers possible. Cool and breezy toward north and eastern mountains, lighter winds and warmer toward southwest Highlands, Cumbria and west Wales. Further into next week, risk spells of chilly and strong west-northwesterly winds particularly for the Highlands, some showery days.
