Any lingering showers soon dying out to leave brief evening sunny spells. Further heavy, perhaps thundery, showers arriving in southern parts, spreading north overnight. Rather breezy on southern coasts. Minimum temperature 14 °C.

A cloudy start with heavy showers, thundery at times. Brighter spells developing, particularly in the west, as showers become confined to eastern areas during the afternoon. Windy on southern coasts. Maximum temperature 25 °C.

Outlook for Tuesday to Thursday:

A mixture of drier periods with sunny spells but also scattered showers or spells of rain. There is a risk showers could be heavy, thundery and slow-moving at times.

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. There are signs that high pressure to the southwest may try to extend its influence across the UK, which could bring more in the way of dry, settled weather as we head further into August. Temperatures will likely continue to be near or above average overall, with a continuing chance of some very warm or hot spells, especially in the south and east, if high pressure wins out for a decent stretch of time.
