High pressure will be dominant across much of the UK at the start of this period. This will bring a good deal of fine and dry weather with spells of sunshine for many. Any showers will probably be confined to the far southwest of the UK but could be heavy and thundery. Temperatures are likely to be well above normal, especially in the south. Later, it will likely become more changeable with some showers or longer spells of rain at times. Rainfall is expected to be highest in the south where some heavy, thundery showers are possible, with drier conditions further north. Some periods of dry and settled weather are also likely to develop at times. Temperatures are expected to be above normal.

Details during this time frame are low confidence. Overall, unsettled conditions with showers or longer spells of rain are expected to be most prevalent. Some heavy and thundery rain is possible at times with a risk of strong winds. Interspersed with this are likely to be some transient periods of drier and more settled weather. Temperatures are expected to be above normal with a chance of some hot spells, especially in the south.
