High pressure is forecast to bring another heatwave to the UK towards the end of August following a stormy start to the month. Brian Gaze, a forecaster at Weather Outlook, shared maps showing shades of dark red and orange hot air sweeping upwards from a south-westerly direction towards the south of England on Tuesday, August 17. He may have been alluding to the fact the high pressure seemed to be coming from the Atlantic, which he added was “not usual”.
He wrote on Twitter: “Remarkable upper level warmth on the UK Met 00z run moving across the Atlantic. Not our usual source.”
The latest heat maps from Netweather show temperatures soaring above 20C in the south-east from Wednesday, August 18, with 24C hitting London and Kent.
However, thermometers could soar further a few days later as highs of 28C bake London on Thursday, August 26, with the charts turning red.
Elsewhere, Essex and Norwich could bask in 27C on the same day, while Birmingham, Doncaster and Leeds could see 25C.
Netweather’s August long-range forecast said temperatures could be “above average” during this period.
The forecast said: “There is quite a strong signal for above-average pressure during Monday, August 23 and Sunday, 29.
“It probably won’t be high pressure dominated throughout, but high pressure will cover much of the country for at least part of the week, bringing spells of quiet, dry and probably sunny weather (although sunshine amounts are sensitive to the positioning of the high pressure areas) and just short-lived interruptions from troughs or frontal systems.
“As a result, there is a dominant signal for below average rainfall, particularly in western parts of Britain due to the below-average frequency of the usual prevailing westerlies.
“Temperatures are not forecast to become exceptionally high, but with a tendency for near-average temperatures early in the week, and generally above-average temperatures establishing mid to late week.”
The BBC’s long-range forecast between Monday, August 16, and Sunday, August 22, predicted high pressure to bring “summer-like” weather to the UK during the second half of the month.
The forecast said: “So far our August weather has been cooler and wetter than normal, and this trend is likely to continue for the rest of this week and into next week.
“However, high pressure lurks in the Atlantic and we anticipate that it will build overhead later in the month.

“This should give us a warmer, drier, and sunnier end of meteorological summer.
“As we make our way into the second half of August (and the final few weeks of meteorological summer), low pressure is likely to become increasingly less influential throughout the week as it shifts away into Scandinavia.
“High pressure is expected to build in from the southwest, and for the first half of the week this means we will likely see some cooler northerly winds with the wettest weather in the eastern half of the country.
“From midweek and through the second half of the week, high pressure is expected to be more influential and shift overhead, bringing some increasingly dry, sunny, and warmer days.
“Temperatures will gradually climb a bit above average for most areas and as we approach late August we can expect some decidedly more summer-like weather for most.”
The Met Office also said warmer weather could hit the south of England between Sunday, August 15, and Tuesday, August 24.
But it added thunderstorms may still lash downpours of rain due to the humid conditions.
The forecast said: “Moving into this period, showers or longer spells of rain are more likely across the north and west on Sunday and Monday where it may also be breezy.
“Drier weather is also more likely across the southeast.
“Moving further into next week and for the rest of the period, high pressure may become more dominant with many areas seeing more settled conditions.
“However, changeable conditions remain possible across parts of the north and spells of heavy showers or thunderstorms can’t be ruled out across parts of the south at times.
“Temperatures expected to be around average for most for this time of year, though with some warmer weather in more settled areas in the south.”
