Exact date heatwave will be over as 'intense thunderstorms' warning issued
The UK could be set for the hottest day of the year for the second day in a row in the run up to a weekend filled with blazing sunshine and scorching temperatures. However, the balmy weather comes with a caveat as the UK may be facing "intense thunderstorms" by week's end, according to recent predictions.
In many parts of the UK today, and over the coming days temperatures are expected to exceed 30C. The reason for the warmer temperatures is due to a "combination of several factors", according to Tony Wisson, Deputy Chief Meteorologist for the Met Office.
A number of areas in the UK have been issued with a heat-health alert warning. The alert affects all regions in England and will be in place from 12pm on Thursday June 19, until 9am on Monday, June 23.
This precautionary system activates to alert citizens about potential health risks due to extreme temperatures.
Brits are advised to brace for "uncomfortable heat" that will last all day and linger through the night. Forecasts suggest "tropical nights" could occur, with night-time temperatures stubbornly staying above 20C, potentially disrupting sleep patterns, reports the Liverpool Echo.
Dan Holley, Deputy Chief Meteorologist for the Met Office, predicts: "The highest temperatures from this hot spell are forecast for Saturday, with low 30s Celsius expected widely across England, and even hitting up to 34°C in certain eastern localities.
"Despite this, the more uncomfortable heat will be in northern and western areas initially, where despite somewhat lower temperatures the air will be more humid.
"While Saturday will be a dry and fine day for many, a few showers or thunderstorms will be possible across northern and western parts of the UK, with an increasing risk of some intense thunderstorms developing across portions of north Wales, northern England and southern Scotland later in the afternoon and into the evening hours, which could bring heavy downpours, frequent lightning, gusty winds and possibly large hail.
"The nights will also be quite warm, with the possibility of temperatures not falling below 20°C in some areas, making it hard to sleep. This is what we term a 'tropical night'.
"Temperatures will ease from the west on Sunday as fresher air arrives from the Atlantic, although parts of East Anglia and the far southeast of England could still see 28-29°C for a time."
From Saturday to Sunday, Glasgow will see temperatures plunge from 27C to 19C, Plymouth's from 24C to 21C and Liverpool's from 28C to 22C.
Further east, Brits will see sizzling temps for another day, with highs of 28C in London, which will drop to 23C on Monday, and plunge from 28C to 23C in Kent, The Express reports.
Heatwave conditions in the UK are met when a location records a period of at least three consecutive days with temperature values meeting or exceeding the heatwave temperature threshold for that location. Across much of the north and west of the UK, this threshold is 25°C, but across Greater London and the Home Counties, the threshold is higher, at 28°C.
The high pressure is anticipated to shift away from the UK early next week, leading to a drop in temperatures. However, the Met Office has expressed uncertainty over how swiftly this will occur and what the peak temperatures across the UK will be.

Dry weather to continue across most of UK as heatwave comes to an end
A northeasterly breeze means northern and eastern parts of the UK will be cooler on these days, reaching up to the low-20s. Some showers with the odd rumble of thunder could hit south-west England and south Wales on Monday and Tuesday, but most places will be dry throughout the week. Experts warn climate change is driving more extreme weather conditions in the UK, worsening drought and dry spells (Danny Lawson/PA) Wetter, windier and more unsettled weather may move in from the Atlantic by Bank Holiday Monday. The continued dry spell comes after officials warned England was suffering from 'nationally significant' water shortfalls, despite rain in July. Sunday's highest temperature was 27.7C in Somerset, while West Sussex and Inverness, Scotland, also reached 27C. Met Office meteorologist Greg Dewhurst said: 'Where people get the sunshine it'll still feel fairly pleasant, it'll just be a bit chillier than it has been of late.' After weeks of warmth, this week brings a change in the air.

'The odd spot here and there might be just holding on to a heatwave, but I think most places have dipped below their criteria and may have sort of come up again.

The national drought group, which includes the Met Office, regulators, government, water companies and other organisations, said on Tuesday that it had met as five areas of the country remained in drought, with six more in prolonged dry weather status. England is seeing widespread environmental and agricultural impacts from the lack of water, which is hitting crop yields, reducing feed for livestock, damaging wetlands and river wildlife, and increasing wildfires, the group said. Experts warn climate change is driving more extreme weather conditions in the UK, worsening drought and dry spells, and making heatwaves more frequent and severe.

UK to be hotter than Ibiza with 29C temperatures - maps show where will burn
With the UK currently experiencing yet another heatwave, weather across the nation is expected to remain dry and sunny next week with scorching temperatures returning for August Bank Holiday weekend Parts of the UK will be hotter than Ibiza next week with Brits set to bask in glorious sunshine over the Bank Holiday weekend. Most areas of the country have enjoyed scorching temperatures in recent days with Britain currently experiencing its fourth heatwave of the year. Temperatures reached 27.4C in Porthmadog, Wales on Saturday while some areas recorded highs of 33C earlier this week. Scorching temperatures are set to remain for the August Bank Holiday weekend, too, with a weather map from Ventusky showing some parts of the country will be hotter than Ibiza on Monday, August 25. It could reach as high as 29C in Norwich, while Ibiza is forecast to be 26C on the same day. The weather map shows a sea of red across most of England with temperatures expected to be hot for many. London could see highs of 27C, in Birmingham it could reach 26C and in Manchester it's forecast to be 25C. It will be a tad cooler in Wales and Scotland, however, although temperatures are still expected to be in the high teens. Forecasters believe it could be dry next Saturday and Sunday, too, with highs of 26C in some places. Temperatures are then expected to dip after Monday but it will likely remain dry, with temperatures in the low 20s. The Met Office's long range weather forecast from Thursday, August 21 to Saturday, August 30 reads: "High pressure is likely to be the dominant feature at first, initially centred near to Iceland, allowing a north to northeasterly airstream to affect much of the UK, leading to rather cool conditions. "High pressure is likely to progress SE across the UK for a time, bringing widely fine and dry conditions and for some, an increase in temperatures, relative to the previous few days. Whilst this is happening a deep area of low pressure is likely to develop in the North Atlantic, linked to Tropical Storm Erin. "The final week of August may see Atlantic weather systems progress over the UK, especially in the north and west, with a small chance of widely wetter and windier weather developing. The evolution of this is highly uncertain though." In the short term there may be an increase in cloud coverage and some chance of rain across the country, with temperatures feeling cooler before they increase again at the end of the week. BBC Weather's outlook for the week reads: "Tomorrow will remain mainly cloudy with low cloud and a few limited sunny breaks. In the evening, cloud will begin to break, revealing plenty of late sunny spells. "Tuesday morning will see low cloud, with a chance of drizzle in places. The odd sunny break will develop in the afternoon. A cooler day. Wednesday will be rather cloudy under areas of low cloud. A few sunny breaks will be possible, these becoming more widespread by the evening. Thursday morning will see cloud and some drizzle. Dry with sunny spells in the afternoon."
