This rain will slowly move southeast, probably reach central areas in the afternoon, although southern Britain should stay dry. On Monday, rain will gradually spread across the south, followed by brighter conditions with blustery showers, and it will feel cooler. Thereafter, it is likely to stay changeable with periods of wet and windy weather interspersed with brighter and showery spells. The heaviest rain is likely in the north, where there's a risk of gales. Generally drier and brighter in the south, particularly in central and southwestern areas. Temperatures varying around average, but becoming rather cold later with an increasing risk of frosts.

Day 16 to 30

For the end of October, unsettled conditions are likely. Bands of rain could move across the country, separated by brighter and more showery conditions, especially in more northern and eastern areas. However, the southwest will probably stay more settled. Into early November, the weather pattern is likely to become slower moving. Longer spells of wet weather are likely at the start of the month, but prolonged drier spells are possible towards mid-month. During the more settled weather, fog and frost with become more likely, particularly in the north. On the whole temperatures are likely to be rather cold, but some brief milder spells are also possible.
