Low pressure will probably move northeast over the UK in a rather erratic manner at the start of this period, bringing some potentially heavy rain and a small chance of strong winds to northwestern areas. Ahead of this, hot and humid conditions are possible across parts of England in particular, though the longevity and extent of any hot weather are uncertain at the moment. Looking towards mid-August, and high pressure is more likely to dominate the weather across the UK. This will bring plenty of dry weather for the most part, though northern areas may see a rather more changeable theme with occasional rain or showers and breezier conditions at times. Above average temperatures are more likely than not, especially in the south, where it could also be rather humid.

High pressure, and therefore largely settled conditions overall, appears more likely for the second half of August. Although dry weather is likely to dominate, periods of rain or showers and thunderstorms may develop at times. Above average temperatures overall seem most likely, with the potential for hot spells to develop, especially in the east and south. By early September, there are signals for high pressure to become less dominant with perhaps a greater chance of some rain, though there is some uncertainty in this aspect of the forecast.
