Planning Outlook
Changeable west-southwesterlies prevail through mid September; often windy, gale-force winds for periods over higher terrain. An active frontal system sweeps southeastward on Saturday with a sustained fall of rain, accompanied by upland gales for most places. Improving for better weather on Sunday, then wind and rain returns into Monday, staying showery into Tuesday. A mixed outlook likely continues later next week with rain most frequent in western Scotland. Temperatures varying, some cooler days especially in Scotland, but often fairly mild further south, at times quite warm and humid.
