UK heatwave forecast: ‘Immense’ 30C Spanish plume to sweep north – Charts show hot air hit

The UK has basked in warm and sunny weather this April with thermometers tipping towards 25C over the Easter weekend earlier this month. Britons have been able to enjoy the pleasant conditions in their gardens and on balconies, while in lockdown, as April 2020 provisionally became the sunniest on record. But, despite temperatures dipping and heavy downpours smashing into some parts of Britain this week - the hot weather will return soon, according to the latest weather charts.

A temperature map by WxCharts shows heat from Spain sweeping northwards, on around May 6, with southern parts of Britain expected to feel the effects.

With Spain very slowly starting to relax lockdown measures to halt the spread of coronavirus, forecasters claimed thermometers would nudge towards 30C.

Meteorologist, Miguel Alvarez, from Meteocat, a Meteorological Service of Catalonia, noted the “positive anomalies across the peninsula starting the weekend”.

Commenting on a weather chart which showed warm air grip Spain, before moving northwards towards northwest Europe, he wrote: “First heat of the season! The temperature will rise above 25C in many places and, at some points, it will be close to 30C!”

The chart appeared to show the hot southerly air strike Britain around May 5 to May 7.

Referencing another weather chart which directly assessed the temperature spike in Spain and Portugal in the coming days, WxCharts added: “Immense heat will be pumped into Iberia heading into next week, just as the initial stages of easing lockdown begin.

“People venturing outside for the first time since March may be in for a bit of a shock as temperatures rise >10-12C above average in places.”

In a final chart, which showed northwest Europe, including Britain, WxCharts suggested that much of “northern and western Europe” would enjoy more “settled” conditions from next week.

They wrote: “Signs of high pressure building in through next week could bring a transient return of fine and settled conditions to much of northern and western Europe”.

BBC Weather claim temperatures in London will be around 20C towards the end of next week, while the Weather Channel suggest thermometers in the capital will tip towards 22C.

The Met Office long-range forecast, starting from May 5, however, suggests “it is likely to be generally unsettled during the first week of May”.

They added that “after the unsettled start to May, there could be a return of more settled conditions, bringing longer drier spells into the second week of May.”

The forecast read: “Temperatures should be around average for the time of year, with some warmer days possible in the east or southeast.”

This week, however, the UK is bracing for heavy downpours and thunderstorms with temperatures dipping across much of the country.

Bringing an end to a mostly dry and settled month, intense showers will lash parts of the country - with the Met Office warning of “a risk of hail and thunder” on Thursday evening.

Moving into Friday, the national weather service said most areas would see “sunny spells and showers” with the rainfall “heavy at times across northern and eastern areas”. Meanwhile they said “lengthier drier spells” would be likely towards the south.

The Met Office’s outlook for Saturday to Monday added: “Sunny spells Saturday with showers in the north and east. Cloudy with rain in the far south Sunday, sunny spells elsewhere with showers in the north. Most places fine Monday.”

It comes after this month provisionally became the sunniest April on record for the UK, smashing figures dating back to 1929, the Met Office confirmed.

Between the 1st and 27th of April, 215.8 hours of sunshine was recorded across Britain, 46 percent above the average for April.

It beat the previous record, set in 2015, of 211.9 hours of sunshine.

It has been the result of persistent high-pressure systems over or close to the UK resulting in an extended spell of fine, dry and sunny weather since late March.

The Met Office also said that central and eastern areas of Britain were among those which were the sunniest this month.

Cambridgeshire with 257.8 hours of sunshine so far this month, beating the 1942 record of 236 hours, was 64 percent above the average. While Leicestershire with 234.2 hours so far, beating the 2015 record of 222.7 hours, was 66 percent above average.

The weather service added that it “has also been a relatively warm and dry month” and said the full April statistics will be released on May 1st.

But, despite the earlier predictions of warm weather sweeping northwards from next week, some forecasters suggest May will instead be bleak - as they noted a concerning historical trend.

Forecasters at have warned: "As we head deeper into May, the weather will most likely become wetter and breezier.

"Looking back through our weather history, a dry April has often been followed by a wetter May, and overall, we expect May rainfall to be near or a little above average for the month."

Leading bookmakers have even slashed odds on next month to go down as the wettest on record.

Alex Apati of Ladbrokes said: "Spring's sunshine looks to be a distant memory with record-breaking rainfall on the way in May."
