Planning Outlook
West to southwesterly winds prevail this week and a series of frontal systems come in from the Atlantic. Rain and drizzle most frequent in west with low cloud often covering hills, typically most extensive in Scotland. Higher cloud bases and drier further eastwards. Temperatures near average, or lower at times in Scotland. Often windy, risk of more extensive upland gales and some heavier rain as deeper areas of low pressure likely move in later in the week. Some indication of a brief settled spell into the weekend and rising temperatures, though northwest Scotland remaining at risk of frontal weather systems.
