BBC Weather breaks silence over 30C heatwave scorching UK 'this week'

The BBC Weather team has broken its silence over when a 30C heatwave will hit the UK. BBC Weather team expert Matt Taylor said that "there’s more optimism to be had over what is coming our way" when looking at the forecasts.

He singled out a high-pressure building on the US east coast, which would "finally" send the jet stream to the north of the UK later this week. There is "a stronger build of high pressure and possible south-easterly wind" then UK temperatures could "climb into mid- to high 20s for some", he said, in a preview of the end of the week.

Exacta Weather's James Madden explained: "There is now a quite high risk threat level and growing forecast consensus for some potentially very warm to very hot conditions to arrive across the shores of the UK and Ireland for in and around this weekend and throughout much of next week (with some variations in intensity across the main third-party computer models).

"Temperatures will now start to rise significantly day by day on the various weather apps for in and around this Sunday, June 23rd, and throughout much of next week, or at least a good few days at the very least. This is also in addition to the predominant warm and summery weather due over the coming days, particularly from around Wednesday of this week (19th June), when some spots in the south will see temperatures leaning more towards or above 25°C (some 6°C above-average for June).

"At the absolute bare minimum, we should be looking at a good 3-5 day very warm and hot period or longer, with potentially excessively hot weather developing during this period (June 23–30) as some major heat gets drawn north thanks to high pressure across our shores."

He said: "Additionally, these temperatures could reach as high as the low to mid-30s in parts of the south at the peak of this within the next several days, with parts further north and into Ireland also potentially seeing the 30°C mark being reached from this type of high pressure setup, or at least the high 20s in many parts."
