Planning Outlook
Damp westerly breezes on Friday will cloak most mountains in cloud and some drizzle, better conditions eastwards. Cool and strong westerlies persist in Scotland on Saturday, then warmer with lighter winds by Sunday. Some patchy rain remaining in west and northwest Scotland over the weekend. Pressure tends to rise from the south this weekend, bringing warmer air and drier conditions to England & Wales, although west coast mountains may hold onto cloud. Into next week, a mixed southwesterly pattern remains, windy at times with periods of rain, drizzle and low cloud most persistent in the west. Warmest in England and Wales, but cooler westerly air likely returns at times mid-late week. Higher pressure then shows more signs of expanding over the country by late next week bringing improving conditions.
