Planning Outlook
Low pressure over the north Atlantic dominates the weather pattern for the week ahead, maintaining unsettled conditions. West to southwesterly winds prevail bringing frequent rain and cloud to western areas, regularly becoming more widespread as weather features come and go. Breaks may form with some bursts of sunshine, though likely short lived. Early indications suggest a deeper area of low pressure late weekend and early next week will bring widespread gales, possibly severe on highest terrain. Becoming more mixed after mid-month with longer periods of dry weather, but a persistent southwesterly regime will continue to draw unsettled spells of weather into Britain, notably in the north.
