As storm-battered Britons give up all hope of setting match to barbecue again this year, forecasters promise a sizzling change is just a couple of weeks away. A swathe of tropical air shows signs of sweeping across Europe and into the UK just before the start of September. Temperatures will to rocket towards the 30C (86F) mark across southern Britain which is in line for the hottest weather, according to forecasting models.
It comes as the UK braves an onslaught of torrential downpours and gales as forecasters warn of wind and rain into mid-month.
Long-range forecasters say a return to the hot weather is likely before the end of August with an Indian summer start to autumn on the cards.
James Madden, forecaster for Exacta Weather, said: “The second half of August is likely to deliver a much more settled weather pattern compared to what we have seen over the past few days.
“While above-average temperatures are expected through the run up to September, it will only take a small nudge in the right direction for Britain to get something much hotter.

Very warm weather could hold out well into September
“Through the second half of this month we are likely to see temperatures rocket sending the country into a heatwave frenzy.”
Exceptionally summery weather could hold out into the start of autumn with September shaping up to be a sizzler, he said.
However, warm air over Britain will lead to unstable conditions sparking thundery outbreaks and further stormy deluges through the coming weeks, he warned.
“Very warm weather could hold out well into September,” he said.
“However these conditions are likely to be accompanied by some rather notable stormy periods.

“While it will continue to feel warm and humid there will be the ongoing risk of potentially heavy and widespread showers.
“But, amid these, it will be warm and sunny for a lot of the time.”
Weather models reveal warm air sweeping in from the Continent towards the end of August pushing temperatures close to 30C (86F) across southern Britain.
Highs of between 25C (77F) and 27C (80.6F) are possible across eastern and central parts of the country with Scotland and the north expected to stay cooler at around 17C (62.6F).
High pressure will build through the run up to autumn bringing a settled spell of weather with plenty of blue skies and sunshine.

Government forecasters predict the weather will settle down towards the end of August before warmer temperatures set in.
It’s long-range outlook promises the chance of ‘lengthy warm spells’ baking Britain through the first week of September.
It states: “Towards the end of [August] there are some signs that longer, drier spells may occur, especially in the south.
“This period will probably start off with changeable conditions, with the best of the dry weather most likely in the south.
“Later in the month, and more especially in the start of September there are tentative signs that high pressure could become more dominant across the UK, which would mean longer spells of dry weather, and more sunshine generally.
“There is a chance of some more lengthy warm spells developing.”
Britons holding out for a last blast of summer will have to put up with a dousing first with wind and rain forecast through the next week at least.
Low-pressure will continue to put the weather through the wringer through the coming days, experts say.
The stormy end to summer is being driven in part by the jet stream which, positioned over the UK, is steering storm systems in from the Atlantic like a conveyor belt.
However government forecasters have started to hint at things settling down by the end of the month and something more cheery on the way.
Met Office spokesman Grahame Madge said: “There are hints of high pressure rebuilding with something more settled in the forecast.”

The Met Office’s long-range outlook predicts warmer conditions across southern parts of the UK into the start of autumn.
It states: “During the [final part of August] there are signals for pressure to build to the west or southwest of the British Isles bringing increasingly settled and warmer conditions, especially to southern areas.
“There are signs that high pressure will increasingly dominate the weather across the British Isles.
“Southern areas are best placed to see the driest and sunniest weather at first, perhaps with some lingering wet and potentially windy conditions affecting the north.
“However, longer spells of dry and sunny weather are soon expected to develop across all parts.”
