The Met Office has issued a warning for thunderstorms and very warm weather across the UK in the coming days, with temperatures potentially reaching as high as 30C.
Warm and Humid Conditions Ahead
High pressure building across the country will bring warm and humid conditions, with temperatures climbing above the seasonal average. By Friday, June 19, temperatures could reach the high-20s or possibly 30C.
On Monday, June 15, there is a risk of thunderstorms in some parts of the country, though temperatures should remain in the low 20s. Cloud and rain will spread from the west on Tuesday, June 16.
Heat Increase from Midweek
Forecasters say the heat will intensify from the middle of the week as warmer air from Europe moves into the UK. On Wednesday, June 17, temperatures in south-east England could reach around 27C, with another surge of warmth expected on Thursday and Friday and into next weekend.
While cloud cover could affect the highest temperatures, there is a chance of 30C being recorded by the end of the week.
Met Office Forecaster Comments
Met Office forecaster Kathryn Chalk said: “We’re definitely seeing a warming trend from midweek onwards.” She added: “Relatively warm and humid nights are also on the cards - not as expected as what we had a few weeks ago, because it won’t be wall-to-wall sunshine like that, we had a stronger signal for that compared to this, but nevertheless it is going to be turning warmer.”
In a post on X, formerly Twitter, the Met Office said: "Generally warm this week but potentially turning very warm, if not rather hot and humid across parts of England. Especially in the southeast from midweek, though it won’t be all sunshine, with the chance of thunderstorms developing."
Long Range Forecast
In the Met Office's long range forecast, covering June 19 to 28, forecasters have warned of 'hot and humid weather'. The forecast reads: "There is the possibility of some hot and humid weather across parts of south and southeast Britain at the start of this period and with it comes the chance of a few thunderstorms too."
To the northwest, conditions will be more changeable at first, but there is a signal for high pressure to build more widely as we move towards the latter part of June. This could bring more widely drier, settled conditions with temperatures probably remaining above average for most.
"There is chance however that the hot conditions, initially in the south could either linger here or, having waned for a time, return northwards accompanied by a thunderstorm risk; this all dependent on the orientation of the aforementioned high pressure."
