Heatwave set to hit parts of UK this weekend as temperatures climb
Forecasters are expecting temperatures to soar to 32C in the south of the UK by Saturday – and most places will reach temperatures above the heatwave threshold by the weekend.
An official heatwave is recorded when areas reach a certain temperature for three consecutive days, with thresholds varying from 25C to 28C in different parts of the UK.
Will this week be: Dry? Wet? Windy? Cold? Warm?

In London – where the threshold is 28C – temperatures could peak at 29C on Thursday and 31C on Friday, before hitting 32C on Saturday.
The hot weather will then spread further north, with Manchester and Newcastle enjoying temperatures into the late 20s by the weekend.
Met Office spokesperson Grahame Madge said: 'Temperatures rising through the week will be home-grown conditions, where we get quite sunny weather, elevating temperatures.
'But as we get nearer to the weekend, that will receive a boost as we start to import warmer air from the south of Europe.
'There will be a low pressure area to the west by the weekend and a high pressure one to the east. Those weather systems will funnel air between them and feed warmer air across the UK.'
The heatwave means some parts of the country will surpass temperatures in holiday hotspots such as Lisbon in Portugal and Barcelona in Spain, which are predicted to reach 29C on Saturday, and Nice, France, where it will be 30C.
Forecasters have warned some rain is still possible in parts by the end of the week, with localised, heavy showers forecast depending on how humid it gets.
Meanwhile, the London Fire Brigade has issued a warning over wildfires ahead of the prolonged spell of hot weather and following one of the driest springs on record.
Charlie Pugsley, deputy commissioner for operational policy, prevention and protection, said: 'Extended periods of hot and dry weather can greatly increase the risk of a grass fire, and particularly when that grass is tinder dry the spread of fire can be rapid. We have seen examples of this in London as well as more recently worldwide, such as in California and South Korea.
'Last month, I wrote to the chief executives of each London local authority, outlining some key measures they can take, such as to create fire breaks, and to welcome the work that councils are already undertaking.'
A drought was declared by the Environment Agency across Yorkshire last week while the north-west of England entered drought status last month.

How hot will the UK weather be for the rest of the summer holidays?
With the school summer holidays now in full swing, will there be a repeat of recent heatwaves? Last month, we enjoyed - or endured - one of the hottest Junes on record, including two heatwaves. The hot weather continued going into July, with a third heatwave of the year recorded. It has recently given way to cooler and wetter weather, with sharp downpours in recent days. But with the school summer holidays now in full swing, what can we expect from the following six weeks? When will the next UK heatwave be? The Met Office defines a heatwave as "when a location records a period of at least three consecutive days with daily maximum temperatures meeting or exceeding" a certain temperature threshold. This threshold varies by area. For example, it is 28C in London, compared to 25C in the North East. But the Met Office does not offer long-term predictions for heatwaves. In recent years, it has become increasingly vocal against media reports, citing questionable sources, predicting extreme weather events such as heatwaves or snow. "At a long forecast length," it says in guidance, "we have to acknowledge that many outcomes remain possible, even though only one can eventually happen. "Weather stories suggesting the 'exact date' a snowstorm or heatwave will hit, in the months ahead, should be treated with extreme caution and these stories risk undermining the credibility of meteorology. "Inevitably, these stories can sometimes prove to be true, but it doesn't mean they can be counted on in any real sense. The only way to be sure is to trust the experts and follow their advice when the weather is uncertain." How hot will it be for the rest of summer? The Met Office provides forecasts looking up to 28 days ahead, with nothing in these currently hinting at anything out of the ordinary for this time of year. Its forecast for 29 July to 7 August predicts rain and showers at the start of this period, especially in the north and west of the country. Dry and sunny weather is more likely in southern and eastern parts of the country, with "temperatures generally near average though with some warmer spells likely". The Met Office forecast for 8 August to 22 August predicts "prolonged dry and sunny weather, especially across the south of the country but potentially spreading to all areas at times. Temperatures will likely be near or above average overall. "There is a chance of some very warm or hot spells, especially in the south and east." Met Office records show the mean maximum temperature in August last year was 19.5C.

Three counties in England set to escape 33C heatwave
Three counties in England are set to escape a 33C heatwave arriving in weeks. The mercury is set to crank up a notch in the first week of August. Weather maps from WX Charts are turning red for large parts of the country on Tuesday, August 5. READ MORE: Inside Midland town where people fall into the canal every year Get breaking news on BirminghamLive WhatsApp, click the link to join According to the temperature is set to start rising from Sunday, August 3. Here, temperatures of 27C and above are set to be widespread across the Midlands, along the South West and South East of England. However some parts of the south could reach 31C. A similar spread of temperature of temperature is expected the following day on Monday, August 4, with highs of 32C in places. But temperatures of between 30C and 33C are set to be widespread on Tuesday, again stretching across the Midlands, South West and South East. In England, an official heatwave is classed when the temperature rises to 25C or above on three consecutive days outside of the South East. That means heatwave status could be reached across dozens of counties in England that day. However three counties in the north of England could miss out on the heatwave. These are: Lancashire, Cumbria and Northumberland. Here, the temperatures are set to reach between 16C and 23C. In its long range forecast from August 5 to 19, the Met Office said: "A changeable westerly pattern will likely continue through into the start of August, with spells of rain or showers mixed in with some drier, brighter days. "There are signs that high pressure to the southwest may try to extend its influence across the UK, which could bring more in the way of dry, settled weather as we head further into August. "Temperatures will likely continue to be near or above average overall, with a continuing chance of some very warm or hot spells, especially in the south and east, if high pressure wins out for a decent stretch of time."
