Planning Outlook

Humid southwesterly winds, gales across many mountains on Friday, plus heavy rain, thundery bursts mixed in. Less windy, but still breezy into Saturday in Scotland, feeling less humid for most, but western Scottish hills at least stay cloud capped and with showery rain. Sunday is a drier day with clearer hills, light winds and feeling warmer. Into next week, a mixed west-southwesterly pattern for Scotland, rain and low cloud most common in the west, drier with higher cloud eastwards and more often dry. Warm and humid for England & Wales - often dry, but possible thunderstorms forming at times - detail more uncertain.
