By Wednesday only a few showers remaining in the far NW. Otherwise, fine and sunny for most. Temperatures still likely warm or very warm. Light winds with sea breezes making it cooler along coasts. Through the rest of the period, plenty of settled and dry weather, most reliably so in the north of the UK - and drier than average overall. Some showers, or even thunderstorms possible, especially at first; greatest likelihood in the south, less so in the north. Warmer than average overall, with the highest chance of this in the west with very warm or even locally hot weather possible. Eastern areas, especially coasts, may however see cloudier, cool periods in a cooler northeasterly wind.

High pressure likely remaining to the north of the UK, with greatest chance of settled conditions continuing. Further unsettled spells with periods of rain or thunderstorms are likely to affect the far south, with a smaller chance that some of these could spread much further north across the country. Later, a change of type is weakly signalled, with an increased likelihood that more mobile spells of weather will affect the UK, although it may take several attempts. This brings greater chance of rain to the west and northwest. Temperatures are more likely to be above average in general - the warmest conditions in the west and south at first. Later, a gradual cooling trend towards average values is the most likely outcome, although briefer hot spells are possible.
