UK long range weather forecast
Low confidence in the forecast for the weekend, with uncertainty in regard to the track and development of an area of low pressure southwest of the UK. This may bring a spell of wet and windy weather northeastwards across the UK during Saturday and Sunday. However, it should stay largely dry in the east and southeast. It will remain very warm in the southeast, with some localised heavy rain or thunderstorms possible. Into next week and we are likely to see a northwest/southeast split in the weather across the UK, with further showers or longer spells of rain affecting northwestern parts, with a better chance of drier and warmer weather in the south and east. Temperatures will generally be above the average for the time of year.
As we move further into August, the final month of the meteorological summer, confidence is low in the forecast with no one single weather pattern looking to dominate. It is most likely that low pressure to the north and northwest of the UK will give further showers or longer spells of rain in the northwest, with the better chance of drier weather in the southeast. Temperatures will likely be above average, especially in western and southern areas. However, confidence falls as we head into late August.
