Planning Outlook
A drier outlook through late April as high pressure resides over Britain, centred generally toward the north. Easterly winds prevail this week, strong and gusty over England and Wales, gale-force in places through midweek. Less windy further north across Scotland and becoming lighter winds everywhere by later in the week. Western mountains generally clear with plenty of sunshine throughout this week ahead, variable cloud at times drifting onto some eastern hills. Some overnight frosts into valleys. Daytime temperatures rising several degrees above freezing to highest tops, warmest in west. Risk of a strengthening chilly northerly wind for a time during next weekend.
