Planning Outlook
Staying unsettled during the next week to 10 days as westerlies prevail - areas of low pressure passing north of Scotland with frontal systems bringing frequent rain, wettest over western mountains in Scotland. Often windy, gale-force westerly winds for periods over higher terrain. Fairly warm and humid on Monday, then on the cooler side for several days, with considerable wind chill on the mountains. Higher pressure and better weather tends to expand further north later in month.
