Sun 27 Oct South West England

Initially breezy or windy with large amounts of cloud and some outbreaks of rain, especially in northern and western areas, with generally drier conditions farther southeast. However, high pressure is likely to build more strongly across southern UK into next week, tending to restrict the majority of any wet and windy weather to the far northwest. That said, areas of cloud trapped underneath this area of high pressure may still produce some drizzly rain in places, with an increased chance of frost and fog under any lengthier clear spells, perhaps slow to clear. Later next week and into the following weekend there may be a tendency for high pressure to retreat, bringing an increased chance of breezier conditions and some rain in places. Temperatures near-average for much of this period.
