Westerly winds prevail into the weekend: Saturday will see extensive cloud and heavy rain develop across Scotland with gales; bands of rain passing to the south and east into England and Wales through Sunday with showers in Scotland. A ridge of high pressure early next week brings warmer temperatures and clearer hills, though western areas likely remain fairly cloudy with some drizzle on the high tops. Westerly flow returns through mid-week and a series of low pressure systems will pass west-to-east across the country with periods of strong wind (sometimes gales), rain, and low cloud, western hill groups always most affected. Mild-to-warm temperatures and sometimes quite humid. Changeable conditions persist into next weekend.
