Showers and cloud cover elsewhere mean temperatures will remain in the late teens for most of England and Wales, while Northern Ireland and Scotland will limit highs to the mid-teens.

A band of rain will sweep across much of Scotland overnight into Saturday morning, before clearing during the day.

The current forecast calls for highs of at least 27℃ in the south east and East Anglia on Tuesday and Wednesday.

Wales and other parts of England are likely to see slightly lower temperatures, but most of the UK is expected to reach at least 20℃.

When is the next heat wave coming?

For now, the Met Office says it sees nothing in its data to suggest another heatwave of the intensity we had in July is on the way.

But the forecaster says it’s “possible” that the threshold for a heatwave will be reached next week as an anticyclone sweeps in from the Atlantic.

This pressure system is different from the one that caused the July heatwave.

“We could see parts of the UK hitting heat waves if above-average temperatures last for three days or more,” said Met Office chief forecaster Steve Willington.

“Temperatures will be several degrees above average in many areas of the UK, particularly in the south, but these levels are likely to be well below the record-breaking temperatures we saw in mid-July.

“While the high pressure builds up, there is very little rain to speak of in the forecast, particularly in areas of southern England that have experienced very dry conditions over the last month.”

Mr Willington added that northern England, Scotland and Northern Ireland are likely to see rain, while southern areas are basking in the expected warm conditions.

The Met Office is currently unsure of what peak temperatures could be next week.

It is said that the sun is less powerful in August compared to July as it is lower in the sky and the daylight hours are slightly shorter.

However, highs are expected in the low to mid 30’s.

The other big unknown is how long this heatwave will last, with the Met Office forecasting it could last into mid-month.

Temperatures of 40℃ observed this week currently occur every 100 to 300 years, but could occur as frequently as every 15 years by 2100.
