UK long range weather forecast
It will be unsettled this weekend. On Saturday, rain will gradually clear the southeast through the day, with sunshine and showers for much of the country. The showers will be heaviest in the north and west, with the risk of hail and thunder. Gales will be possible in the far northwest and it will feel cool for the time of year. The south will become drier on Monday but for the start of September, it will probably be fairly unsettled nationwide. The heavier rain will be most likely in the northwest, with southern 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 generally be on the cool side, especially in the north.
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.
