For it to be called a heatwave the temperature criteria have to be reached for at least three days in a row.
Tuesday will still be very warm in East Anglia and south-east England with temperatures up to 27 or 28C. But next week the jet stream pattern in the Atlantic will straighten again and we will be back to more changeable weather with temperatures nearer normal.
We’ve seen a few of these “heat spikes” this summer.
I’ve noticed over many years of presenting the national weather forecast that it used to be the case that we needed three or four days of dry weather to lift the temperature to 30C.
Are things changing and these temperature rises happening more rapidly?
It is difficult to quantify a shift like this, but it could be that we are seeing another impact on our weather patterns as a result of climate change.
