Planning Outlook
Westerly winds prevail this weekend and early next week, then southwesterly into midweek, bringing spells of rain, drizzle and some showery falls; low cloud persistent across hills, particularly in the west. Upland gales early on Saturday tend to lessen, but staying breezy; lower wind speeds for Scotland on Sunday. Rather cool this weekend and Monday, single-figures Celsius on high terrain. Then more humid, and warmer, especially England & Wales. More prolonged heavier rain possible for western Scotland Monday-Tuesday, risk of gales again on high tops. More uncertainty later in the week as a slow-moving area of low pressure is nearby, but risk areas of heavy rain and showers.
