Wednesday's weather hit headlines as the temperature rocketed to over 36C in Heathrow.
The heat was so extreme that the elderly and those observing Ramadan were warned to take care and stay out of the sun as temperatures rocketed.
So what does this weekend's weather have in store?
A spokesman for the Met Office said: "Friday will be a dry, fine day with plenty of sunshine; the cloud will increase as the evening goes on.
"The top temperature will be around 27C.
"Saturday morning will be clear, cloudy but dry. We will see some bright spells, with highs of 26C."
He said: "There has been a weather warning issued for Friday -From 7pm to 12 noon on Saturday there is the potential for thunderstorms.
"There will be heavy downpours, thunder and lightening.
"Sunday will be dry and fairly cloudy, with increasing sunshine throughout the day. The top temperature will be around 22C.
"UV levels for Friday and Saturday will be 7, which is fairly high, so be aware, and take reasonable precautions when going into the sunshine, such as wearing plenty of suncream."
Dr Paul Cosford, director for health protection at Public Heath England, said: "Older people and those with long-term illnesses are particularly vulnerable to the effects of very hot weather.
"It's important to look out for them, help them stay hydrated with plenty of cool drinks, and keep indoor areas as cool as possible."
