The Met Office said temperatures will rise over the next couple of days in southern England, peaking at around 27C to 28C in parts of the South East on Friday.
The weather service said Thursday will be a largely dry day for many, with temperatures into the low-20Cs across much of England and Wales.
Those further to the north-west, initially in western Scotland and Northern Ireland, will see a cold front with rain arriving by Thursday afternoon, and this will gradually transition to more mixed conditions over the weekend.
It comes as much of England, including London and the South East, remain in drought following an extremely dry spring and summer that was also marked by successive heatwaves and hot weather, putting extra pressure on water resources.

Met Office deputy chief forecaster Dan Holley said: “Once early fog patches clear in the south, Friday will be exceptionally warm for late September, especially in the south-east closest to an area of high pressure over the nearby continent.
“A weakening cold front will drift gradually south-eastwards overnight and into Saturday, with temperatures falling back closer to average over the weekend.
“This sets up a mixed weekend of weather, much of Saturday will be fine and dry before an increasing chance of rain or showers on Sunday, especially in more western parts.”
The Met Office said there are emerging signals for “increasingly wet and windy weather next week”.

The weather service said there are increasing signals of a period of wet and windy weather on Tuesday and into Wednesday, with the chance of some coastal impacts in the west and south-west.
Mr Holley said: “While details are naturally uncertain at this range, a particularly deep area of low pressure could pass close to the UK during the first half of next week.
“This may bring some wet and windy weather for some, which coupled with high spring tides could bring impacts to some coastal areas in the west.”
