Rather cloudy and humid, but turning fresher later this week.
Tuesday will start off rather cloudy with a few drizzly patches here or there. It will brighten up during the afternoon with some warm, sunny spells developing, so the most of us will see sunshine at some point. Maximum Temperature 25C.
Staying mostly dry and on the mild side. The cloud will thicken through the early hours of Wednesday morning, however, bringing outbreaks of drizzle to western parts. Minimum Temperature 15C.
Another warm and rather cloudy day with patchy drizzle in the west, but some brighter intervals too. More persistent rain by evening with fresher, clearer conditions following from the northwest. Maximum Temperature 23C.
Outlook for Thursday to Saturday:
Thursday and Friday will be cooler, with sunshine and showers. Showers most frequent and blustery on Friday. Early rain on Saturday will clear to sunnier weather from the west.
Day 6 to 15
This weekend,, many places will have sunshine and showers. These showers will be heavy at times, with a risk of hail and thunder particularly in the north, with sunnier spells in the southeast. It will be windy at times, and some more persistent rain may arrive from the west later on Sunday. For Bank Holiday Monday, it is most likely to be unsettled in the northwest, with longer spells of rain and some strong winds. Drier and brighter conditions are generally likely in the south and east. This northwest, southeast split is then quite likely to continue. Temperatures will start rather cool, but they will recover to around the seasonal average, with perhaps warmer conditions at times in the southeast. Drier weather may become more widely established into early September.
Day 16 to 30
For the start of September it looks likely that the weather pattern will only change slowly. Areas of high pressure and associated settled weather will probably increasingly dominate, with some longer dry spells, particularly for northwestern areas compared to much of August. However there are also likely to be some more changeable weather at times in the north and northwest, with outbreaks of rain and strong winds, with these conditions perhaps extending southeastwards at times. Temperatures by day are likely to be generally warmer than average, especially for the southeastern half of the UK but generally nearer the seasonal average further northwest, and there will be an increasing chance of chillier nights anywhere, as would be expected going further into September.
