Planning Outlook
A damp start westerly pattern continues at the start of the week, particularly in Scotland, then a drier and warmer window builds into the middle of the week: very warm in England and Wales, spells of sunshine spread northward, and lighter wind. Some patchy rain continues through late week in western Scotland though detail is uncertain and more often dry. High pressure is indicated to expand across Scotland through next weekend bringing more widely dry and warm conditions in the extended outlook into mid July - easterly winds likely develop, particularly England and Wales; a chance of some thunderstorms.
