Brits are gearing up for a sizzling sequel to this year’s summer as another heatwave is anticipated to strike the UK, possibly marking the hottest day of 2023 thus far—it could all kick off in just a matter of days.

Circle April 27 on your calendars—that’s the expected date heralding a return to hot weather, providing a pleasant reprieve from the current slew of dour grey skies and intermittent showers.

Advanced weather models illustrate the progression throughout the week with splashes of yellow, amber, and orange across Britain’s charts, teasing the onset of our second round of summery warmth.

Projections from a fresh WXCharts.com map indicate temperatures soaring over 20C nationwide, with a sweltering 26C not off the cards., reports the Mirror.

Meanwhile, a Met Office forecast covering April 20 to April 29 speaks of “Mainly unsettled conditions are likely across the UK at the start of this period”.

Adding more detail, the report said: “Showers or longer spells of rain are probable across many regions, these heavy at times with a risk of hail and thunder, perhaps accompanied by strong winds.

“Some drier and brighter interludes are also likely at times, but probably with large amounts of cloud. Temperatures will generally be near average”.

Utilising Met Desk data, the WX Chart maps suggest that Norfolk, Suffolk, Cambridgeshire, Greater London, Bedfordshire, and Oxfordshire could be in for some of the highest temperatures.

The Met Office said: “Temperatures will probably be around or slightly above average”.

The forecast also looks ahead to mid-May temperatures, with the report indicating: “Late April into early May will probably see a good deal of settled weather with high pressure patterns most likely to dominate”.

Yet, it notes that “whilst some spells of more unsettled weather are possible at times – these perhaps more likely towards mid-May – much of the period is expected to be largely fine and dry. Temperatures are expected to be near or slightly above average”.

The BBC predicts a cooler Wednesday, with rain expected in northern and western parts of the UK, but conditions improving on Thursday to warmer and drier weather.

Friday, however, is set to bring changes, as an Atlantic low ushers in rain across Ireland, Wales, and Scotland, while eastern England should remain dry.

Looking forward to May, the BBC’s outlook is positive, anticipating ‘a near-average rainfall and modest warm anomalies’.
