The first few days of this period are likely to be rather changeable, with many parts of the UK seeing showers or perhaps some longer spells of rain. Within this broad pattern, there is potential for a low pressure system to develop just to the west or possibly over the UK, which would bring the possibility more widespread rain and perhaps strong winds. By the latter part of August, there are signals for high pressure to become rather more dominant again, with more in the way of dry weather developing once more, especially towards parts of the north and west. Temperatures are more likely to be above normal than below overall, though the possibility of widespread or exceptional heat is perhaps a little lower than in recent weeks.

High pressure will probably be dominant in the vicinity of the UK during this period, meaning periods of dry weather for many regions. However, some more unsettled or changeable interludes are probable at times, bringing showers or some longer spells of rain, although overall rainfall amounts are more likely to be below average than above. Temperatures will likely be above average and some spells of hot weather and heatwaves are possible, especially in the south.
