Wednesday:

Mainly dry through Wednesday with bright or sunny spells, perhaps the odd light afternoon shower. Rain arriving from the west late evening. Maximum temperature 21 °C.

Outlook for Thursday to Saturday:

Cloudy with outbreaks of rain Thursday. Further rain on Friday, mainly in the west, heavy at times, brighter spells in the east. Rain clearing eastwards Saturday with showers following behind.

Early in this period, low pressure is likely to exist to the northwest or north of the UK, allowing areas of cloud and rain to spread across the UK from the west, though some more settled interludes are also likely, especially in the southeast. Breezy at times, with temperatures mainly near or below normal. Remaining changeable thereafter as weather systems to move across the country from the west, with northern and western areas typically wettest and a greater chance of dry conditions prevailing in the southeast. There is, however, a smaller chance for either unsettled weather to be more widely prevalent, or for a more quiescent period to develop across the south. Overall, temperatures will likely be near normal, but may feel cool in the west at times.

Through this period, there remains a slightly increased chance of more settled spells of weather developing at times, particularly in the south, and the likelihood of this has been gradually increasing over the past few days. However, there is still a substantial chance of other outcomes too, with more changeable periods also likely. Overall drier than average conditions are more likely than wetter than average, and warmer than average conditions are weakly favoured too.
