However it’s not all good news, as the humid air will apparently cause thunderstorms to break out across the country by Friday afternoon.
The Met Office issues a severe weather warning on Thursday, as forecasters predict lightning and hail across some parts of the country.
Isolated severe thunderstorms are likely to begin from midday Friday, followed by more widespread rain until the early hours of Saturday.
And the storms are apparently all due to an area of warm air moving across from France into Britain on Thursday night, pushing the temperature up but also causing disruption.
On top of rain and lightning, we can also expect Friday’s pollen levels to be extremely high - so watch out hay fever sufferers.
Met Office forecaster Dean Hall said: “Friday will start very warm and humid in the South but end up with thundery rain.’
‘Maximum temperatures, particularly in the South East, could reach 25C or 26C. There might be somewhere reaching 27C or even 28C.’
So, looks like it’s a day for the sundress, wellies and waterproof then?
