Britain braces for possible return of scorthing heatwave

Plummeting temperatures will briefly cool sun-stricken Britons amid warnings to brace for a possible return of the heat dome.Fresh Atlantic winds will nosedive thermometers more than 10C this week as rain douses the flames of the historic heatwave.But the next fire blast is on the way, with experts warning July threatens temperatures back in the high 30Cs.With all the ingredients simmering after two months of record-breaking heat, Briton is facing a summer of heatwaves. TRENDING Stories Videos Your Say Met Office meteorologist Annie Shuttleworth said: “If we see high pressure dominant, maximum temperatures could be close to the high 20Cs by the weekend.“Further north, we are more likely to see unsettled low-pressure systems dominating, but we could see high pressure becoming more dominant across the UK.“This week, temperatures will fall to much lower than they have been recently, closer to average, but there is uncertainty over the next two weeks how much temperatures will vary.“There is a good chance we see further hot spells through the next few months.”Weather models for the start of next month have started to tout another blast in the high-30Cs.Once again, in the firing line for the third scorcher of 2026 will be southern and eastern Britain, with a fresher outlook for Scotland and the north.A dome of high pressure similar to the heat dome that sizzled Europe and Britain last week is about to rekindle the flames.Jim Dale, meteorologist for British Weather Services and co-author of ‘Surviving Extreme Weather’, said: “It is currently on the edge, and although the models are backing off a bit, there are signs that temperatures through the end of this week and into July will start to rise again.LATEST DEVELOPMENTS:Andy Burnham 'set for first public spat with Donald Trump' over Britain's faltering defence spendingBomb team deployed to seaside village after suspected explosive found on beach'Do your part!' Furious French blame US for deadly European heatwaves“We are talking about the return to high pressure and depending how this plays out will dictate how hot it gets.“But given what we have had, there is very little doubt that through the coming months we will dip in and out of periods of very hot weather.”After surging temperatures toppled a raft of spring and summer records, Britain is about to enjoy a week of ‘normal summer weather’.Southern counties will dip to around average or just above, while the north will be slightly fresher.Overnight temperatures, which during the heatwave hovered above a sweaty, tropical 20C, will return to sleep-friendly lows.Met Office meteorologist Liam Eslick said: “Temperatures overnight are going to be a lot more comfortable, and the humidity is going to be a lot lower.“On Monday, it is going to be a normal summer’s day, with some bright sunshine turning a little bit hazy through the afternoon with some higher cloud drifting in.“Temperatures will be around the low to mid-20Cs, so there are still a few places that are above average, but in western Scotland, a few degrees below average.”The jet stream, which holds a ribbon of fast-flowing air over the north hemisphere steering our weather, will pull stormy weather systems in from the Atlantic.These will shove the high-pressure, ‘blocking’ heat dome back out east, blowing in cooler, fresher winds.Met Office meteorologist Aidan McGivern said: “It is going to feel more comfortable and start to cool down because the jet stream is back in charge of the weather.“It is picking up low pressure, and there are more lows to come in this week, and the most weather pattern for Tuesday is for high pressure near the Azores trying to extend to the southwest but not quite making it.“It is a very changeable scene for the first of July, with low pressure wanting to bring outbreaks of rain and a brisk wind into the northwest.“There will be some rain and showers, and no sign of the hot and sunny weather returning, and temperatures returning to average for the time of year.” Our Standards: The GB News Editorial Charter
