UK long range weather forecast
It will become more unsettled on Friday, especially in the north. Occasionally heavy rain or showers will be likely here, with the risk of strong winds and it will feel rather cool for the time of year. The south may remain dry, especially in the southeast where temperatures will be above the seasonal average. Over the weekend, and into the start of September, it will probably be fairly unsettled nationwide. The heavier rain will be most likely in the northwest, with southeastern parts receiving the longest dry and sunny spells. However, there will be a risk of thundery showers breaking out across the southeast at times. Temperatures will vary around normal, with a possibility of further warm spells.
There are signals that changes in the weather patterns across the UK will become slow during this spell. At present it is considered that the predominate weather type will be unsettled conditions, leading to an increase in the chance for above average rainfall through September. However, more settled conditions are likely at times, especially around the middle of September, with temperatures likely to be near to or slightly above normal for the time of year.
