Very hot weather will continue in general until at least Thursday across the highlighted region, although some variations from place to place and day by day are likely. Temperatures by day are widely expected to exceed 30 Celsius, with the hottest areas potentially peaking around 38-40 Celsius within the embedded red warning.

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.

Red Extreme_heat Warning 24 9:00 - 25 21:00

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.
