The probability of heatwave conditions in parts of England and Wales
between 0900 on Monday and 0900 on Tuesday is 60%

Increasingly hot and humid air is expected to spread northwards across
England and Wales over the weekend and into next week. Heat-wave
conditions are now likely to develop for some central, southern and
southeastern areas from Monday onwards. These conditions may spread to
other areas later in the week.
