Information on update: The warning area has been expanded, particularly across northern England, south Wales and southwest England. 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. Cooler conditions may begin to become established from the west following this period, but confidence is low.
