Planning Outlook
High pressure centred over England and Wales during the second half of this week, whilst weak fronts drift past northwest Scotland, giving some patchy rain or drizzle, but improving toward the end of the week and weekend here. Most places dry and increasingly warm with southerly breezes. A greater risk of some rain or showers by Sunday in the west. Low pressure then moving toward the south of Britain by early next week is likely to strengthen an easterly wind and may bring some rain or showers for a time.
