Friday
Higher pressure builds on Friday. This brings a warm day with good spells of sunshine over much of England and Wales as well as eastern Scotland and much of Ireland. The moist southwest flow is likely to be giving some drizzle in western Ireland, western Scotland and perhaps the far west of Wales in the morning, although this will be fading from most areas through the afternoon. Fog could affect those western coasts from time to time too. Highs at 28C in the southeast, 22 to 26C for many other areas but 17C in northwest Scotland.

Friday Night
Showery outbreaks of rain may continue to plague western parts of Ireland and northern and western parts of Scotland through the night and into Saturday morning. Cloudier skies too for northwestern areas, clearer skies to the southeast. Where winds are lighter over southern Scotland and northern and central England a few mist or fog patches could develop. Overnight lows generally at 11 to 15C, milder southeast.

Saturday
A very warm south to southeast flow on Saturday bringing a fair day for most. There will be good spells of sunshine and it should be dry. Cooling sea breezes developing around the coasts. A front to the west may bring some rain into the far west of Ireland and perhaps northwest Scotland. The threat of some fog affecting coasts of southern Ireland. Highs at 23 to 29C, but 17C in the Hebrides.

Sunday
A slack airflow on Sunday with pressure lowering. It is likely to be another very warm day with broken cloud and good spells of sunshine. Some mist and fog patches around southern and eastern coasts. The risk of an afternoon shower in northwest England, western Scotland and Ireland as cloud builds and fresher air arrives here. Highs at 20 to 26C, but 30C in eastern England.
