Burgess Hill, England, United Kingdom Severe Weather Alertstar_ratehome

The heatwave which is affecting a large part of England and Wales is set to continue during Friday. The focus of the highest temperatures on Friday is likely to shift towards east and southeastern England, where maximum temperatures in the shade could exceed 36 Celsius, perhaps rising to 38 Celsius in some places. However, following another very warm night, the greatest likelihood of high impacts are expect to be within this Red warning area during Friday. 

The heat will be accompanied by high humidity, exacerbating the potential for discomfort and health impacts, with very warm and humid night times also reducing the ability for people to recover overnight.

Significant disruption to daily life is likely and the public should take every effort to make precautions and adapt their daily routines where possible to cope with these levels of heat, which up to now have been extremely rare for the UK.

Thunderstorms are expected to move northeastwards across parts of England and Wales during the early hours of Friday, clearing during Friday morning. Whilst many areas will miss them, thunderstorms may produce sudden, gusty winds with 50 to 60 mph possible, particularly in the south and west of the warning area. Frequent lightning, hail and heavy rain (possibly 15-20 mm in an hour) are additional hazards.

Night temperatures remain unlikely to fall below high teens Celsius for most with some places probably remaining in the low 20s Celsius. These temperatures will be accompanied by high humidity.

Very hot weather will continue to affect much of England. Temperatures by day are widely expected to exceed 30 Celsius, with the hottest areas potentially peaking around 38 Celsius in eastern and central England. 

Overnight, temperatures are unlikely to fall much lower than high teens Celsius, and some places will not fall below low 20s Celsius. These high temperatures will also be accompanied by high humidity.

Cooler conditions will slowly begin to become established from the west following this period, although very warm conditions are likely to remain across east and southeastern England through Saturday, albeit not as hot as earlier in the week.

Information on update: The warning has been extended south across Dorset, Hampshire and Sussex as confidence in extremely high temperatures and humidity has increased in these areas. The warning end time is now the end of Thursday. During the heatwave expected to affect a large part of England and Wales this week, the highlighted area now looks increasingly likely to see a two to three day period where maximum temperatures in the shade exceed 37 Celsius, perhaps rising to 38 to 40 Celsius in some places. The heat will be accompanied by high humidity, exacerbating the potential for discomfort and health impacts, with very warm and humid night times also reducing the ability for people to recover overnight. 

Significant disruption to daily life is likely and the public should take every effort to make precautions and adapt their daily routines where possible to cope with these levels of heat, which up to now have been extremely rare for the UK.
