Planning Outlook
The weekend ahead will be generally unsettled: windy and feeling cool with low pressure bringing heavy showery rain widely. High pressure to the southwest will extend to the Isles early next week, settling the weather and allowing sun to break through Monday and Tuesday. Into the week, a mixed westerly regime dominates with greatest risk of rain toward northwest Scotland, drier and warmer further south and east. Several fronts will drift towards Britain from the northwest but high pressure to the southwest will prevent extended unsettled periods. England and Wales may only see occasional rain.
