UK Weather: Temperatures to continue to rise
The UK baked in its hottest temperature of the year on Tuesday when 32.2C was recorded at Heathrow Airport in west London, while yesterday a 31.1C high was recorded in Ross-on-Wye, Herefordshire. But forecasters have now warned that heavy rain and thundery showers could lash the nation over the weekend, especially on Sunday. The Met Office has also issued a yellow warning for rain for central and southern parts of England and Wales from early on Saturday to midnight on Sunday.
However, Brian Gaze, a forecaster at Weather Outlook, predicted a heatwave may return by mid-August as temperatures could climb to the “upper 20Cs” again as high pressure from the Azores arrives.
He told Express.co.uk: “Computer models are indicating a changeable start to August with temperatures a little below the norm and the risk of showers or longer spells of rain.
“In general the driest and warmest conditions are likely to be in the south, but even there, things are looking mixed.
“There are tentative suggestions of high pressure building towards the UK from the Azores during the middle third of the month.

“That would increase the chance of drier and warmer periods, particularly in the southern half of the UK where temperatures could climb into the mid to upper 20Cs.
“At this stage, the computer models aren’t suggesting very hot conditions returning, but there is still plenty of time left this summer for things to change.”
At the moment, the latest heat maps from Netweather show the southeast of England basking in highs of 23C on Wednesday, August 4, while Kent and Essex are also hit with 22C.
The maps then show the hot air pushing further north a few days later on Saturday, August 7, as the Yorkshire Dales and Leeds could see 23C.

On the same day, Birmingham and Gloucester could also bake in highs of 21C and down in the southeast, London, Brighton and Southampton are expected to see 23C.
Weather Outlook’s seasonal forecast added August could start on a wet note due to mixed conditions of heavy showers and dry weather.
But then the second half of the month could see temperatures reach “above average” and “very warm periods”.
It said: “Mixed with showers or longer periods of rain but also warm and fine spells.

“The driest weather will probably be in the south and east, but a heightened risk of heavy showers or thunderstorms means local variations could be large.
“Temperatures should be above average when aggregated over the period as a whole.
“In the second half of August, the chance of settled and very warm periods increases.
“Showery spells of rain are still probable, particularly in the north and west.”

BBC Weather’s long-range forecast said another heatwave could hit the nation for a “week or so” later in August.
The forecast between Monday, August 2, and Sunday, August 15, said: “We consider that there is about a 30 percent chance that high pressure ridges could become stronger and more resilient. This would lead to longer-lasting dry and warm periods.
“Even if this came off, though, Scotland and Northern Ireland could remain more susceptible to wet and windy periods.
“Although computer model guidance is struggling to pin down the pattern this far ahead, there are some signals that towards mid-August another high pressure system could begin to assert itself, with drier and warmer weather returning for a while.

“Confidence on this is low, however, and there is a 35 percent that unsettled weather could continue. If high pressure does shift overhead, there is a growing risk of another heatwave which may last for around a week or so. This is perhaps more likely a bit later in August.”
The Met Office also predicted “warmer conditions developing” during August.
The long-range forecast between Friday, August 6, and Friday, August 20, said: “To begin the period, mixed conditions look likely to remain for a few more days, with no dominant weather type.
“Drier conditions with sunny spells are likely to be interspersed with showers or longer periods of rain. As we head further towards mid-August, it is most likely to become more settled with drier and warmer conditions developing.”
