A cold front is likely to make some progress eastwards across the UK on Thursday, with the potential for heavy showers and thunderstorms. Some hot or very hot conditions may persist in the east ahead of this, especially in the southeast. Into the weekend, confidence falls low, but following the cold front, fresher conditions will be the most likely. A northwest to southeast split will be the most likely scenario. The northwest is likely to see further spells of rain and strong winds at times, with temperatures near or a little below average. The south and southeast are likely to see localised heavy rain, with thunderstorms possible, but it will stay warm or very warm into the start of August.

As we move into early August, the final month of the meteorological summer, confidence is low in the forecast with no one single weather pattern looking to dominate. It is most likely that low pressure to the north and northwest of the UK will give further rise to showers or longer spells of rain in the northwest, with the better chance of drier weather in the southeast. Temperatures will likely be above average, perhaps mostly in western and southern areas. However, confidence falls as we head through August.
