Headline:

Turning fresher with heavy thundery showers.

This Evening and Tonight:

Mostly dry at first this evening, but showers will move in across the country from the west overnight, these heavy at times, and possibly thundery in northern parts of Wales. Winds mostly gentle, with some clear spells. Feeling cool. Minimum temperature 11 °C.

Thursday:

Showers will continue to feed in from the north on Thursday, which could turn thundery at times. Showers turning lighter and more isolated through the afternoon. Slightly cooler than Wednesday. Maximum temperature 21 °C.

Outlook for Friday to Sunday:

Temperatures staying below average into the weekend. Scattered showers continuing on Friday, but slowly becoming more settled again heading into the weekend with an increasing number of sunny spells.

Largely dry and settled early next week as a ridge of high pressure continues to extend across the country. Likely turning more unsettled during the week and through to the turn of the month as low pressure becomes more dominant. This bringing showers or longer spells of rain, perhaps heavy, to most if not all areas at times though still some sunny interludes. Possibly windy at times too. Temperatures likely near to average though varying with some short-lived warm and humid spells possible, especially in the south.

A rather unsettled start to autumn is most likely with all areas probably seeing a mixture of showers or longer spells rain interspersed with drier interludes. Temperatures likely varying around average, some warm or hot spells are possible but unlikely prolonged in early September. By mid-September, there may be an increase in the extent of drier, more settled weather, especially in the south and east, though signals become very weak.
