Britain could be set for its hottest day of the year so far on Friday - with temperatures reaching a Mediterranean—worthy 27C.
Indeed, southern parts of Britain will be hotter than Lisbon in Portugal and Madrid in Spain.
Speaking to the Mirror, Met Office forecaster Dan Williams said: "Warmer air from the Azores will see temperatures rise, with Thursday forecast 24C and Friday potentially in the ballpark of the hottest temperature of the year."
Warning that Wednesday will still be relatively cool, Leon Brown, meteorologist at The Weather Channel, agrees things will warm up on from Thursday.
He told Aol Travel: "Temperatures will lift to the low 20s across central and southern Britain on Thursday and up to 25C in Hampshire to Dorset.
"On Thursday night to Friday, showery rain will spread north from France and during Friday thundery showers are likely across central and southern areas.
"It will still be warm though with temperatures as high as 25 to 27C in the south east."
After a warm Friday, however, the weather takes another turn for the worse. Leon added: "A band of steady and moderate to heavy rain looks likely to develop on Friday evening and night across central Britain with some high rainfall totals.
"This weekend, the band of rain will likely lie across northern England on Saturday and then swing back south west to Wales and south west England on Sunday.
"To the south it'll be dry and bright on Saturday with temperatures around 21C while the rest of the UK will be rather cool in a chilly north east wind.
"It will turn cooler everywhere by Sunday with a lot of cloud over the south. Temperatures only 10C to 12C over parts of Wales to the Midlands and north east England and Scotland so feeling more like March than June!"
