This weekend and early next week, winds often light, some areas of low cloud and constant rain, but overall frequently dry (despite fairly low pressure). Least rain will be in northern Scotland. Nevertheless one or two areas of strong winds. A weak ridge of high pressure will bring mostly fine conditions to the mountains early next week, but further strengthening winds and rain are likely to spread east across Britain mid-week. From then rain and low cloud will be frequent, particularly western mountains.
