A plume of warmth from the Azores will push up temperatures – with the balmy air potentially bringing a short Indian Summer to Britain.
The first signs of change will come with clear skies and sunshine is brought in from high pressure across the Atlantic from the Azores – and there’s a chance that the mercury could soar into the high 20s C for some next week.
Before then, there could be some rain moving northeastwards with some heavy bursts possible in the northwest. But elsewhere, temperatures will jump from today with the best of the sunshine in southern regions, reports Mirror Online.
A brief cooler interlude is expected towards the end of the week, but forecasters are confident of brighter and warmer weather from next week towards the end of the month.
Met Office spokesman Oli Claydon said: “It will feel nice in the sunshine during the bright spells, and we could see temperatures of 24C (75.2F) in southern Britain on Tuesday and around 23C (73.4F) on Wednesday.
“The calm and mild conditions are due to an Azores high blocking unsettled conditions from moving across the country.
“This Azores high will exert its influence largely over southern Britain into the weekend.”
It will feel cooler in Scotland and parts of northern England although the mercury will lift into high double figures, he said.
Forecaster The Weather Outlook predicted some unseasdonal temperatures early next week and added: “Computer models are suggesting the possibility of it turning very warm.
“There is still time for things to change but currently it looks as though temperatures in the south may be hitting the upper 20Cs and even a sneaky 30C isn’t out of the equation.
“If you’ve packed away the barbecue it could be time to think about bringing it back for one last hurrah. The nights are rapidly pulling in but the warmth may not be done with us yet.
“It’s also worth noting the warm up looks less marked the further north and west you ahead. It fits in nicely with the pattern of high pressure becoming centred over continental Europe and a southerly air stream feeding up across the UK.
“Parts of the north west remain more prone to a cooler Atlantic influence.”
The Met Office also suggested better weather on the way. It said: “Further rain and gales are possible on Sunday across the north before a spell of settled weather is likely to develop for a time from the south into early next week bringing increasingly warm and dry conditions.
“Uncertainty remains as to how long this settled period will last, but a return to changeable conditions seems probable during the second half of the week.”
