Sat 20 Sep Highlands and Eilian Siar

The broadly unsettled conditions look to continue during the first part of this period. All areas are likely to see some further spells of wet and at times windy weather, interspersed with brighter, showery interludes. By the start of the following week, a ridge of high pressure may extend eastwards towards the UK, bringing an increasing chance of longer periods of drier weather to northern areas initially, whilst low pressure remains closer to the south or southeast. Towards the end of this period, high pressure may be rather more dominant across the UK. A cooler interlude is likely for a time through next week, with chilly nights and fog patches likely under the influence of high pressure. Temperatures probably return closer to average by late September.
