With 3C temperatures forecast in Portugal, it may be a while before the effects of the heatwave can be felt on Britain’s plains
If your weekend plans are simple – a trip to the farm shop, a stroll in the park or an afternoon poolside with a cold Pimm’s and a cuppa – then you may want to get them done early.
A lot of the heatwave’s late impact may be felt further north, with temperatures of about 34C predicted in parts of north-west England later this week. Even in south-west England, forecasters are predicting that it will reach 31C on Friday.
It will be a much cooler day on Thursday in northern England, with temperatures peaking at 30C in the north-east and north-west, but 31C is still a long way off in the south.
Thursday 27 July
There will be a risk of showers in northern parts of the UK on Thursday, while the south remains dry. Temperatures will reach 25C in London, so it may be a good day to make sure you have got the latest version of your emails and transport data switched on for the roads.
The national weather service has warned that in the western Scottish borders and the north-west of England, there could be the odd thunderstorm, which will be particularly heavy and potentially leading to some flash flooding.
For those planning to watch the England v Croatia game at Wembley, temperatures are expected to fall into the 20s as the afternoon progresses.
Friday 28 July
Temperatures will still be 30C or higher in central England, the east Midlands and south-east, but as the day progresses the heatwave looks set to start to ease.
Saturday 29 July
Next weekend will start with showers in northern England, including Glasgow, and the north-west, but on Saturday south-east England will be hit with more rain, mainly in East Anglia and across Kent and east Sussex.
In Wales and south-west England, there will be some relief from the sun – mainly early on Saturday – but temperatures will still be in the low 30s.
In Scotland, there may be showers in areas such as Dunblane on Friday and Fife on Saturday but temperatures will be in the low 20s.
Sunday 30 July
We have already seen some of the effects of the heatwave. The hattrick of washouts last weekend hit transport, and this week has brought a drop in temperatures and thunderstorms. Saturday and Sunday may bring more of the same.
Monday 31 July
Temperatures are expected to fall again across the UK. While parts of northern and central England may drop to low 20s, southern and eastern England are forecast to remain well above average. In both the south-east and south-west England, temperatures are set to stay in the low 30s.
