UK set to roast with 20C temperature jump and two English counties hottest

The UK faces a 20C roaster as temperatures skyrocketing by a sizzling level before the end of the month. Temperatures look set to rocket by nearly 20C in just days as glorious sunshine returns up and down the country.

A three-day mini-heatwave this weekend saw temperatures top 21.5C at times in the East of England and the south, including London. It made the weekend the hottest of the year so far - and there's plenty more to be had too.

Forecasters are predicting 17C highs on Sunday afternoon for Wales, while 16C highs are seen across the Midlands. It marks a fresh change from Monday's weather and the midweek period which will see temperatures hover around freezing at times in parts of the North of England and Scotland.

Devon and Cornwall looks set to experience temperatures in the high teens, while 16C is expected in Herefordshire and Gloucestershire. It marks a bounce back from a -1C low forecasted by projections at WX Charts, which uses Met Desk data.

The Met Office outlook for the rest of the week reads: "Generally dry for the rest of the week though cloudy at times with some showers possible. Temperatures around the seasonal average and a noticeable fresher feel to the weather."

The BBC Weather team input adds: "Cloudier for many on Wednesday with frequent showers in the north and east. Some could be wintry over higher ground here, while the south and west will see lighter showers and sunny spells. Clear for most by evening, but cloudier in Northern Ireland.

"Showery rain in the far north on Thursday, sunnier in the south. Patchy drizzle in places and partly cloudy on Friday." The Met Office adds: "From Friday onwards and into the new week a build of high pressure will likely occur, meaning more in the way of dry weather across the UK as a whole. Cloud cover is rather uncertain, as some cloudy and clear regions are expected, with the chance of frost and fog where the clearer conditions are to be found overnight."
