UK long range weather forecast
Likely remaining warm, perhaps very warm and humid towards the southeast at first with the risk of thundery showers across central and south-eastern areas. Elsewhere sunny spells and fresher, with some rain and thicker cloud towards the north and west at times. The fresher air is then likely to gradually spread to the rest of the country bringing a change to widely cooler more changeable conditions towards the end of the week, with a low risk of warm and humid air returning to the far southeast at times. This will likely bring occasional spells of rain or showers interspersed with drier and sunnier conditions. Overall, temperatures will likely average out to be close to normal.
Updated:
Low confidence through this period due to mixed and weak signals. However, a west to south-westerly direction is most likely. This would favour occasional spells of warm to very warm conditions, with hot conditions probable at times towards the southeast. This may bring the possibility of thunderstorms in the east to southeast. Overall, rainfall amounts will likely be close to average for the time of the year.
