Planning Outlook
Increasingly warm for Scotland, hot for England and Wales this week. Southwesterly winds easing for much of Scotland but remnants of fronts bring further low cloud and drizzle to the west late this week. Locally a chance of thundery downpours in eastern Highlands later Friday, some of which may linger into Saturday but likely fading. A generally fine summertime outlook through the weekend and well into next week as high pressure expands northwards to broadly reside across Britain. Warm but generally pleasant summer temperatures next week. Sunshine and fair-weather cloud, many hills often clear. Easterly breezes for England and Wales.
