A broad northwest/southeast split in the weather looks most likely through much of this period. Towards the northwest, Atlantic frontal systems will bring occasional rain and cloudier skies at times, along with breezier conditions, though there should be some drier, brighter interludes too. Further south and east, high pressure will likely dominate with a fair amount of dry and sunny weather to be had. With this, there is a signal for increasing heat and humidity and the potential for another period of hot weather to develop by the second weekend of July, probably lasting into the start of the following week. Given the anticipated high temperatures, the chance of thunderstorms also increases, though widespread rainfall across southern areas looks unlikely.

A continuation of the broad themes from earlier in the month at first, with high pressure probably dominating the south and lower pressure more favoured to affect the north and northwest. Temperatures are likely to end up above average overall with a continued, and perhaps higher than normal, chance of occasional hot spells or heatwaves, especially further to the southeast. However, by the turn of the month, there is a signal for perhaps more widely unsettled weather to develop, though the details of this are rather uncertain.
