Planning Outlook
A core of high pressure drifts over the country on Sunday, bringing light and varied wind, dry weather, and minimal hill cloud fairly widely. Northwest Scotland will see a westerly breeze with a little drizzle and lingering hill cloud. It will feel warm in England and Wales in the sunshine, but fair weather cloud will tend to build in the afternoon. Monday is settled too, but high pressure slips away to the northwest, facilitating a southeasterly wind into Wales, later more widely. Tuesday sees a return of low pressure from the south: temperatures will rise and patchy rain will increasingly spread northward with some local stronger wind. Conditions likely continue to unsettle as next weekend approaches with bands of heavy rain forming, varied conditions continuing through the weekend, and likely staying warm and somewhat humid.
