By the weekend, a weather regime dominated by westerly winds is likely to become established. While showers or longer spells of rain will remain possible for all parts of the country, the focus of wet weather is expected to be across the west and northwest, especially over hills where rain could be prolonged. The highest chance of drier and sunnier weather can be expected to the east of hills, and across southern and eastern areas, and maybe later in the period if high pressure tries to build into the southwest. It will be breezy at times, especially in further north. Temperatures are most likely to be near to average for the time of year, with only a small chance of hot spells during late July and the start of August.

A changeable pattern will likely continue through into the start of August with spells of rain or showers mixed in with some drier, brighter days. However there are signs that high pressure may become more dominant, which could bring more in the way dry, settled weather more widely as we progress further into the month. Temperatures will likely continue to be near or only a little above average overall. However, there is a possibility of some very warm or hot spells, especially in the south and east.
