On Sunday spells of heavy and possibly thundery rain may affect Scotland and the far east and northeast of England, especially during the morning. Elsewhere sunny spells and scattered showers, but with some central and southeastern parts staying dry. At the start of next week there'll most probably be a good deal of dry weather with sunny spells, with showers most likely in the west and southwest where there may be some longer spells of rain at times. During the first week of August wet and occasionally windy weather is expected to mainly affect the northwest, with a better chance of drier and warmer weather in the south and east. Temperatures will generally be above the average, and possibly hot at times in the southeast.

As we move further into August, the final month of the meteorological summer, confidence is low in the forecast with no one single weather pattern looking to dominate. Whilst the north and northwest may see some spells of unsettled weather at first, with the best of the drier weather across the southeast, by the third week of August it looks as though settled weather may develop more widely for a time. However, there is also an increasing risk of showers or thunderstorms developing in the south. Temperatures are likely to be above average, perhaps more especially so in the south and southeast where hot weather on the near continent may spread in at times.
