The details during this period carry low confidence. High pressure will probably be increasingly displaced to the north through the first part of this period, allowing areas of low pressure to potentially make inroads from the Atlantic. This brings an increasing possibility of stronger winds and rain, some of which could be heavy and thundery, especially for southern and western areas, but this perhaps becoming more widespread with time. Overall, temperatures look to remain above average, with the potential for some further hot spells, especially in the south. One of the determining factors of the forecast through this period will be the behaviour of what is currently Tropical Storm Erin as it progresses into the North Atlantic; this being a quite typical source of uncertainty in late summer.

Details during this time frame also carry 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 at first in the south.
