This Evening and Tonight:

It wiil be a fine evening for most in the late sunshine. Patchy high cloud may linger in places overnight, otherwise clear skies. Feeling humid. Light winds. Minimum temperature 14 °C.

Thursday:

Clear skies will see a day of prolonged sunshine. Sun perhaps turning hazier at times through the afternoon as high cloud drifts in. Feeling very warm or hot. Humid overnight. Maximum temperature 30 °C.

Outlook for Friday to Sunday:

Fine and sunny and hot through the period, although feeling slightly cooler along the coast. Perhaps some cloudier starts in the east at the weekend. Humid at night. Light winds.

The heatwave from the weekend will be gradually eroded from the west early next week as a cold front arrives from the Atlantic. This will bring the chance of some heavy rain or showers, perhaps thundery, especially in northern and western areas. Towards and beyond midweek, a rather changeable pattern is anticipated with some rain or showers possible at times, which could be heavy and thundery, and particularly focussed in western and northwestern areas. Longer drier spells are most likely towards the south and east, although even here some showers may be possible at times. Temperatures are likely to remain above average, especially in the south and east where further spells of very warm or hot weather remain possible.

A continuation of the broad themes from earlier in the month at first, with high pressure probably dominating the south and lower pressure more favoured to affect the north and northwest. Temperatures are likely to end up above average overall with a continued, and perhaps higher than normal, chance of occasional hot spells or heatwaves, especially further to the southeast. However, around the turn of the month, there is a signal for perhaps more widely unsettled weather to develop, though the details of this remain rather uncertain.
