High pressure is to the east of the UK on Tuesday pulling in a very warm south-easterly flow. Once any mist and fog patches clear it will be a dry and fine day for most with the best of the sunshine across England, Wales and Ireland. There will be some cloud and drizzle across the far north and northwest of Scotland. A warm to very warm day again with highs at 22 to 28C, possibly reaching 30C in one or two spots.
Cloud looks to build across the far southwest of England and Wales and across Ireland overnight bringing the risk of a few patchy bits and pieces of lighter rain here. The far northwest of Scotland may also see some drizzle. Generally elsewhere it will be dry with clear spells. A mild night with lows between 12 to 17C.
The area of high pressure remains to the east on Wednesday. More cloud spreads in from western areas into central regions while eastern regions seeing the best of the lasting sunny spells. Outbreaks of rain, heavy at times and perhaps thundery, will affect southwest England, parts of Wales and across much of Ireland. Northern into central Scotland also seeing cloudier skies and some rain. Elsewhere, it looks to remain dry and feeling very warm again. Highs into the upper 20s across England into eastern Wales and parts of Scotland too. Between 20 to 25 elsewhere.
Low pressure dominates the scene on Thursday, bringing a more mixed day with outbreaks of rain, some thundery. The rain may turn heavy and persistent at times for some. Rather cloudy, however, sunny spells are expected across parts of England and Wales and particularly the southeast where temperatures will be very warm again. Highs up to 27C in the southeast, generally elsewhere highs between 17 to 25C, cooler again across northern Scotland.
