Sunday will be fresher than of late, with sunny spells and occasional showers. The showers will be heaviest in the northwest, where there will be a risk of thunderstorms and coastal gales. However southeastern areas will stay dry, warm and humid. By Monday, the fresher conditions will spread to all areas. It will likely stay drier across the south and southeast though. Thereafter, as we go into early July the most likely scenario is for a continuation for warm or very warm, perhaps locally hot, and potentially thundery, weather possible for parts of the UK. There is likely to be occasional spells of dry and fine weather though. Temperatures will return closer to normal after a potentially very warm or hot spell of weather at the start of the period.

During the first half of July confidence in the forecast becomes very low. It seems most probable that high pressure will be close to the north and east of the UK, with lower pressure and Atlantic frontal systems nearer the southwest. This would bring more unsettled weather over southern and southwestern parts of the UK, with some rain or showers. However, the north and east would see more in the way of drier and settled weather. Temperatures during this period are likely to be around or slightly above normal.
