Planning Outlook
West-northwesterly winds prevail this weekend and early next week, transitioning to southwesterly through mid-to-late week, bringing spells of rain, drizzle and some showery falls; low cloud persistent across hills, particularly in the west. Lower wind speeds for Scotland on Sunday, staying quite breezy England and Wales. Rather cool this weekend and Monday, single-figures Celsius on high terrain. More prolonged heavier rain possible for western Scotland Monday-Tuesday. More humid and warm into mid and late week, especially England & Wales which could become hot later in the week. More uncertainty later in the week as a slow-moving area of low pressure is nearby, but risk areas of heavy rain and showers into next weekend as well.
