Planning Outlook

Pressure builds this weekend, centred over England and Wales where it will be warm and sunny. To the north of the high, a blustery and gusty south-westerly will persist across the Highlands with patchy rain and hill fog,mainly in the west and northwest. Very warm by Sunday and Monday valleys of Wales and England, mid to high 20s. Low 20s glens into southern and eastern Scotland. Next week, high pressure extends over Scotland, cutting of the low cloud and drizzle from northwest Scotland by midweek with warm sunny weather, cooler in the north and east coat. Still very warm into the valleys of England and Wales with extensive sunshine.
