Planning Outlook

Low pressure facilitates a strong westerly Atlantic breeze over the weekend: blustery winds, low cloud, damp conditions for Saturday, then widely heavier rain is expected by Saturday night, accompanied by winds strengthening to gale force over many hills. Remaining very windy through Sunday and Monday with mountain gales; cooler too, with heavy showers, particularly frequent in western Scotland, a risk of hail and thunder. A changeable week follows, winds generally easing and likely a period of rain for England and Wales Tuesday. Eastern Scotland may be substantially dry with regular sun. Some improvement likely late week into the weekend.
