Over the course of next week, temperatures are looking likely to creep up. The Met Office forecast highs of 28C could be possible later in the week, and the weather could have “all the ingredients” for thundery downpours.
On Sunday the UK is forecast to see highs of 20 to 21C, with 22C possible in some areas.
Western parts of Scotland are widely expected to see 15-25mm of total rainfall over the next 24 hours, however, some regions could see 50-60mm of rain.
The Met Office also forecast totals of 70mm of rainfall could also be possible in some areas during this period.
On Sunday night there will be a north-south split, with rain heavy at times in the north.
Further south is likely to be clearer, and it’s not likely to be an especially cold night.
Temperatures are forecast to start warm at the beginning of next week, but the Met Office are predicting temperatures will climb even higher over the next few days.
Met Office meteorologist Alex Burkill told Express.co.uk: “Monday is a damp start across northern parts of the UK, there will be outbreaks of rain across Northern Ireland, much of Scotland, and also some parts of northern England and north Wales.
“Tuesday and Wednesday are pretty decent days, still a bit more cloud towards the north and north west on both days and this does bring the risk of a few spots of rain, but the further south and east you are the better the chance you’ll have largely sunny skies.”
Temperatures will rise for Tuesday, but at the moment it looks likely Wednesday will prove even hotter.
Mr Burkill said: “Tuesday we’re looking at highs of 25C, we may possibly get 26C.
“Wednesday is looking like the warmest day this week at the moment, we could get highs of 26 to 27C, maybe even a little bit higher – high 20s isn’t out of the question for Wednesday.
“The warmest parts are likely to be towards more eastern parts of the UK like the London area, East Anglia but also further north up into Lincolnshire and Yorkshire, that’s where we’re most likely to get above 26/27C.”
On Thursday there are “all the ingredients” for thunderstorms to potentially develop.
Mr Burkill added: “Heat lasts until Thursday, it depends what happens but Thursday could actually be a little bit hotter, but that does bring the risk of some thunderstorms developing with the warm air, which we often see at this time of year.
“Thursday brings the risk of some heavy thundery downpours, but away from these and any sunny spells it could again be hot with temperatures in the high twenties, it’s hard to put a figure on it at the moment but 27/28C seems quite likely, but things could change quite drastically.
“Then its a more unsettled end to the week with rain spreading from the west for Friday.”
