Staying largely dull overnight with the occasional clear spells in the east. Patchy rain mostly affecting the north and over the hills. Staying humid overnight. Minimum temperature 12 °C.

Sunday:

Generally drier on Sunday. Still rather cloudy to start but the brighter and sunnier breaks developing more widely than Saturday into the afternoon. Very warm and humid. Maximum temperature 26 °C.

Outlook for Monday to Wednesday:

Very warm and humid again on Monday with lengthy spells of sunshine. Cloud building from Tuesday with periods of rain into Wednesday, perhaps heavy at times, but turning fresher.

Perhaps some residual heat and a small chance of a thunderstorm left in the far southeast at first on Wednesday, but many other areas will be cooler and fresher with sunshine and just a few showers. Generally speaking, high pressure is more likely to dominate through the first part of July, bringing plenty of fine weather, particularly across southern areas of the UK. Into the second week of the month, a gradual transition to rather more changeable conditions is forecast to take place, especially further to the northwest. Here, showers or some longer spells of rain are possible, along with breezier conditions at times. The drier, brighter and warmer conditions are more likely to hang on in southeastern areas for longer.

Changeable conditions are most likely through the middle part of the month, with showers or longer spells of rain, but also some drier, brighter interludes. Areas towards the northwest are more likely to see the wettest conditions, whereas those towards the southeast stand a greater chance of longer drier periods. However, there is also the chance of occasional thundery outbreaks, which would bring heavy rainfall to any part of the UK. There are hints that more widely drier conditions may develop by the latter part of the month. Overall, temperatures are forecast to be above average, with greatest chance of very warm or hot spells in the south or southeast.
