A weak front drapes over western parts of the UK and Ireland on Monday which could trigger a few showers in the west and perhaps longer outbreaks of light rain for the far west of Ireland and Scotland. Most other areas should be dry with plenty of sunshine though there is a chance of a thundery shower developing over southwestern parts of England and Wales later. A fresher day for western areas with high temperatures at 18 to 20C; warmer to the east at 23 to 30C.
A front edges eastward over the island of Ireland bringing rain to much of the country by morning. Light rain also persists over the far west of Scotland while thundery showers continue over the southwest UK moving northeastward into the Midlands by morning. Elsewhere it is a dry night with mostly clear skies. Overnight lows at 8C in the north of Scotland, 18C in the southeast of England.
Fronts remain over western Ireland and western Scotland on Tuesday bringing cloud and some outbreaks of rain. Showers developing for eastern Wales and southern and central parts of England later. Most other areas are dry with sunny spells, the best of these in the east and south. Highs at 20 to 25C for most. Just 16C in northwest Scotland; 28 or 29C in southeast England.
Fronts edge east across Ireland and the UK on Wednesday. This triggers some heavy bursts of rain in Northern Ireland and across Scotland. Showers developing over northern and central England and Wales too. Brighter conditions follow to the west for much of Ireland and later for western parts of the UK. Highs near 26C or 27C in southeast England, 15 to 24C for most.
