Monday will start fairly cloudy with some showers feeding southeastwards across the country. Most places will settle into a dry day though with increasingly sunny weather. Pleasantly warm, although breezy. Maximum temperature 21 °C.

Outlook for Tuesday to Thursday:

Tuesday promises to be a dry day with warm sunshine and winds will ease. Patchy cloud is likely thereafter, though staying mostly dry and turning very warm in the sunshine.

Many parts of the UK are expected to be part way through a period of high temperatures and humidity at the start of this period. The duration, geographical extent and intensity of the heat are all rather uncertain at present, but there is the potential for some very hot weather to be realised, especially across some inland southern and eastern areas. With this also comes the possibility of thunderstorms, in part because of the high temperatures, but also in association with any frontal systems moving in from the west, which would ultimately usher in cooler and fresher conditions. Towards the latter part of the period, northwestern areas stand a greater chance of experiencing rather more changeable conditions, with drier and occasionally hotter spells more likely further southeast.

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 remain rather uncertain.
