The UK is bracing for a significant temperature surge, with forecasts indicating a 20C increase before the month's end. The nation is set to bask in a warm glow as temperatures are predicted to soar by nearly 20C in a matter of days, bringing back the much-missed sunshine.

This past weekend saw a mini-heatwave that pushed thermometers to a pleasant 21.5C at times in the East of England and the South, including London, marking it the warmest weekend of the year to date. And it seems there's more warmth on the horizon.

Weather experts are forecasting highs of 17C in Wales by Sunday afternoon, while the Midlands can expect temperatures around 16C. This is a stark contrast to the chilly start of the week and midweek temperatures, which are expected to dip to near freezing in some northern parts of England and Scotland.

Devon and Cornwall are anticipated to enjoy high teen temperatures, with Herefordshire and Gloucestershire likely seeing 16C. This is quite the turnaround from the -1C low suggested by WX Charts projections, which rely on Met Desk data.

The Met Office's outlook for the upcoming week states: "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.", reports Birmingham Live.

The BBC Weather team has forecasted: "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."

Meanwhile, the Met Office has indicated: "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."
