Temperatures are expected to nudge towards 22C on Thursday as hot air returns to parts of the country, just days after a swelteringly hot Easter Sunday. But Britons may only be able to enjoy the warm weather in gardens and on balconies for a brief period of time, as thunderstorms could quickly sweep across parts of the country towards the end of the week. According to the latest WxCharts, warmer air appears to sweep across the country on Wednesday and into Thursday.
Temperatures are expected to near 22C on Thursday in the south of the UK, with charts showing much of Britain turning red and yellow as the warmer weather moves in.
BBC Weather charts also show the country turn warmer – with yellow and orange colours sweeping across the country representing the hotter conditions.
BBC Weather forecaster Louise Lear said: “That cold front continues to push itself through Scotland and behind it colder air.
“At the same time an area of low pressure moves in from the southwest and it feeds in this warmer air for a time – so warmer still, Thursday looks likely to be the warmest day of the week.”
Brian Gaze, from the Weather Outlook, claimed temperatures would pick up once again this week and could even nudge towards 22C in London on Thursday.
But the weather forecaster warned heavy rain would smash into some parts of the country towards on Friday.
He said: “Thursday low pressure will be approaching from the southwest. It leads to a risk of showers in southwest England and southern Wales.
“The rest of southern and central Britain has warm sunny spells. Temperatures could reach 22C (72F) in the London area.
“The north remains dry but cloudier conditions spread southwards and in the northeast it will be a lot cooler.”
Moving towards the weekend, Mr Gaze said: “Friday looks dry in central and northern regions. In the south and particularly the southwest heavy showers are expected.”
He warned that at times showers “could merge to give longer outbreaks of rain” with conditions feeling “cooler in the wet areas and eastern Britain”.
Mr Gaze added: “During Saturday there is a risk of showery rain in southern and central regions.

“However, by Sunday showers probably become more scattered again. In sunny spells, it should feel quite warm in the south but the north and east it stays cooler.”
Met Office spokesman Grahame Madge said the meteorological agency could be issuing weather warnings for thunderstorms on Friday.
BBC’s Carol Kirkwood warned of thunderstorms sweeping up from the southwest throughout the week after the warmer air moves in.
She said: “Temperature-wise today, generally 17C to 18C as we sweep further south.
Thursday looks likely to be the warmest day of the week
BBC Weather forecaster Louise Lear
“Through the course of this evening and overnight a weather front will continue its way southwards. Taking its cloud and patchy rain into northern England and Northern Ireland.
“At the same time – we will have some showers coming up from the southwest and we could also see some patchy mist and fog forming across some southern counties of England.
“Thursday, a dry and bright start, a weather front still sinking south with some patchy and light rain still with it, and some showers coming in from the southwest.
“One or two of those could be sharp and we could also possibly hear the odd rumble of thunder. Temperatures could get up to 22C around the London area.”
The BBC Weather forecaster explained how the weather system, currently sitting above France, would shift northwards on Thursday and into Friday.
Ms Kirkwood explained “some of those will merge to bring longer spells of rain which could be heavy and thundery”, in the south.
Despite the unsettled conditions predicted, leading bookmakers have slashed odds on this spring to go down as the hottest on record.
Alex Apati of Ladbrokes said: “The odds are continuing to tumble on this spring going down as the hottest ever.”
