After some evening sunshine eastern parts will have clear skies at first overnight. However, a band of rain, some heavy, will move eastwards across the country. Clearer spells returning later. Minimum Temperature 12C.

Fri 29 Aug Wales

Low pressure will dominate the weather during the middle and end of the week. There will be further showers or longer spells of rain, and it will remain rather breezy.

Sat 30 Aug Wales

Low pressure is expected to largely dominate through this period, bringing bands of rain or showers to most if not all parts from time to time. Some heavy rain is possible at times, especially in the west, but this possibly occurring more widely at times. Periods of windier weather are also likely. Confidence in the details remains on the low side, something not untypical at this time of year, largely due to the potential for further systems to develop in the tropical Atlantic, which can have profound knock-on effects on the weather patterns upstream of and over the UK. Temperatures should generally be around average, likely with some day to day oscillation, depending on sunshine amounts.
