Planning Outlook
A mixed but milder outlook. Showery bursts of rain Sunday and Monday, passing eastwards during the daytimes, generally improving afternoons in western areas. By later Monday, strengthening southerly winds and rain moving into Wales from the southwest.

A drier and much warmer theme later in the week as higher pressure builds.
