Planning Outlook

A drier and warmer window builds into the middle of this week: very warm in England and Wales. Still low cloud persistent especially toward northwest Scotland, but spells of sunshine spread northward, and lighter wind. Some rain late this week in western Scotland though mostly light and patchy, many places dry. High pressure expands across Scotland through the weekend bringing more widely clearer hills, dry and warm conditions in the extended outlook into mid July - easterly winds likely develop, particularly England and Wales; a chance of some isolated thunderstorms occasionally.
