Planning Outlook
Low pressure over the country during midweek brings strong winds, rain and thundery showers. Trending toward westerlies later in the week and into weekend, by then most rain and low cloud in western Scotland, but showery rain elsewhere at times, accompanied by periods of strong to gale force mountain winds at times. Generally fresh temperatures widely, often in mid-single figures over Scottish high tops. Despite falls of rain, beware of ongoing fire management restricting access to hills locally.
