Rain on Wednesday, then feeling fresher on Thursday

This Evening and Tonight:

Staying dry and on the mild side for much of the night. The cloud will thicken through the early hours of Wednesday morning, however, bringing patchy outbreaks of drizzle to western parts along with low cloud, mist and some fog. Minimum Temperature 16C.

Wednesday:

Cloudy with rain pushing southeastwards. This may be heavy at times, particularly over high ground. However, by the evening it will turn drier in the north and west. Maximum Temperature 23C.

Outlook for Thursday to Saturday:

Thursday and Friday will be fresher, and breezy with a few showers. Rain is likely later on Friday, clearing on Saturday morning, then it will become brighter though breezy.

Day 6 to 15

After a cold and dry start on Sunday, cloud and rain is likely to spread east into western areas later in the day. For Bank Holiday Monday, the rain is likely to gradually continue south and east, with drier and brighter conditions following. Temperatures should be around the seasonal average. The middle part of the week is likely to see a north-south split in the weather. Northern areas will generally be more changeable with some rain or showers at times, but it is likely to become more settled in the south with warmer temperatures. Drier and warmer weather may become more widely established into early September, as high pressure starts to build in from the south.

Day 16 to 30

Through the beginning and middle part of September, there is an increasing chance that much of the UK will see a good deal of dry, warm and settled weather. Northern and western areas could occasionally have wet and windy spells towards the middle part of the month, but these should be short-lived. Temperatures are likely to be generally warm across the UK, with a chance of very warm conditions developing in the south.
