Last year's record-breaking 40C heatwave could return to the UK within a month, one forecaster predicts.

July 19, 2022 saw the hottest ever recorded temperature in Britain at a sweltering 40.3C. Weather experts believed the mercury could reach similar levels in June, but the sun quickly gave way to thunderstorms, high winds and downpours in July.

However, this could soon change if crucial circumstances are met. It comes as Europe is being struck by the scorching Cerberus heatwave sweeping the content, pushing temperatures over 40C.

And it could be heading straight for the UK next.

Jim Dale, Senior Meteorological Consultant at British Weather Services, told the Daily Star we can expect changeable conditions with intervals of rain over the next two weeks or so.

However, the start of next month could be a very different story. He said: "August, first couple of weeks, I would say there’s a 10 per cent chance - no more - of seeing 40C in the UK, getting back to record levels.

"Getting into the 30-35C, I’d put that chance at around 30 per cent. That’s about where we are with it returning to those zones."

However, for 40C heat to occur, he said the "right synoptic situation" needs to take place. "Drafts of air from the south," are the crucial factor.

He added: "So until we get one of them - and we’re not going to see that for at least a couple of weeks - then we’ll remain on the fringes."

Mr Dale went on to say "the risk will be there" because of where we are with climate change: "It cannot be denied. We’re in a changing world and we’ve reached a line in the sand."

Over the next few days however, the Met Office is forecasting rain and showers, turning heavy and thundery in Scotland.

Sunny spells and showers elsewhere, although some eastern areas staying dry, remaining breezy with the strongest winds across northern areas.

Monday should see winds get lighter. Any early brightness on Tuesday will then give way to cloudy skies and rain for some.

It's expected to get brighter on Wednesday and Thursday with isolated showers and warm, sunny spells.
