The end of August should see a split in the weather across the UK, with warm, dry, sunny conditions prevailing across many areas, but in particular the southeast. In the northwest conditions will be cloudier with rain followed by periods with sunny spells and showers. The wind may be strong at times too, with temperatures here closer to average. During early September there may be a transition to more unsettled conditions nationwide. However, any rain will be heaviest and most frequent in the northwest, with southeastern parts receiving the longest dry and sunny spells. There is a risk of thundery showers breaking out across the southeast at times. As we head through early September we should see weather patterns become slow evolving again with temperatures near to or above average.

From early through to the middle of September there is a trend for the weather patterns across the UK to become slow moving with a 'blocked pattern' becoming dominant. At present it is considered most probably that this will cause a tendency for conditions to be most often unsettled, leading to an increase in the chance for above average rainfall through September. However, more settled conditions are also probable at times, especially around the middle of September, with temperatures likely to be near to or slightly above normal for the time of year.
