The heatwave warning has been raised to "level three" by the Met Office for north-west England.
It said the hottest weather was expected over western England on Friday, with the east becoming cooler.
Level three warnings are in place for the South West and the West Midlands, but warnings for south-east England and London have been reduced to Level two.
The warning alerts healthcare services to help those in high-risk groups such as the elderly and young children.
Level three alerts are triggered when threshold temperatures have been reached for one day and the following night, and the forecast for the next day has a greater than 90% confidence level that the day threshold temperature will again be met.
The threshold temperature for north-west England is 30C (86F).
Eastern areas will see cooler conditions on Friday, with London and south-east England reduced to a level two warning, and the East of England reduced to a level one warning - the minimum state of vigilance.
Level two warnings are also currently in place for the East Midlands and Yorkshire and the Humber. These alerts are triggered by a 60% or higher chance of the threshold temperature again being reached on the second day.
North-east England remains on a level one warning.
Scotland, Wales and Northern Ireland are not included in the alert system.
Hot weather poses a real danger to health.
The very elderly and the seriously ill are most at risk but people at the peak of physical fitness can still succumb, particularly if they are under extreme physical exertion.
The main threat is dehydration - as we overheat we can soon lose more fluid than we take in.
The body can no longer cool itself and our core temperature, which should be a stable 37C, rises.
At 40C the cells inside the body begin to break down and the body starts to malfunction.
It even stops being able to sweat, leading to more overheating.
The heart rate and breathing rate speed up and the person may fit, hallucinate or become unconscious.
Heatstroke is a medical emergency that needs urgent treatment.
The Met Office said it would become less hot for a time over the weekend, but temperatures are expected to increase again early next week with a likelihood of level three being reached again in some areas.
It is the UK's first prolonged heatwave since 2006, with six consecutive days of temperatures above 30C (86F).
Research by the London School of Hygiene and Tropical Medicine has estimated there might have been between 540 and 760 extra deaths in England and 60 to 100 in Wales due to the hot weather.
In other developments:
- Walkers and climbers in Scotland are being warned to guard against potentially fatal dehydration, heatstroke and heat exhaustion as temperatures soar
- In Hampshire, gritting lorries have been out on the roads trying to deal with melting road surfaces
- But the Highways Agency says it will not have gritters on standby for major routes in the South East. It says it is confident road surfaces can deal with the heat
- Fire crews are tackling a mountain fire at Wattsville, Caerphilly, which has reignited. Four hectares of trees, grass and bracken said to be well alight. The fire has smouldered for three days
Wednesday was the hottest day of the year, with 32.2C (89.9F) recorded at Hampton in south-west London.
