Dry and hot conditions are expected to peak on Thursday, with concerns that the extreme could impact railway lines and power networks.

Today, it will be mostly dry with some patchy cloud and sunny spells, with Tuesday expected to be the same.

On Wednesday, the sun will be shining across the country and temperatures are expected to rise to the mid 30s on Thursday with very across the south.

Met Office meteorologist Tom Morgan said: “We’ll probably see highs reaching the mid-30s quite widely on Wednesday, and indeed on Thursday too for and .

“On Wednesday, probably the Midlands, maybe a little bit further south, the M4 corridor, west of London, up towards the Midlands, is where we might have a small chance of reaching 36C in one or two spots.

“But Thursday at this stage looks the most likely hottest day of the week.

“So 36C is a fairly reasonable probability locally on Thursday and there’s a small chance it could get even higher than that.”

Half of England and all of Wales have been plunged into drought and more regions could be declared when officials meet today at the National Drought Group.

Currently, more than 25 million people have restrictions on water use, the Environment Agency said, with millions under hosepipe bans, including all South East Water and customers.

Tom said: “If it wasn’t for this incredible that we’re currently seeing, then we’d be talking about these temperatures as being really, very unusual.

“But of course, we’ve had such an exceptional summer, people have become a bit used to it.

“There is a potential for impacts, so impacts to infrastructure, things like railway lines and power networks, impacts to vulnerable people as well.”

officials have warned of the effect on vulnerable people in the upcoming hot weather, with possible impacts in health and social care settings and a potential rise in deaths because of the heat.

Yellow heat health alerts issued by the UK Health Security Agency are in place for the East Midlands, West Midlands, South East, South West, East of England, Yorkshire and the Humber, and London.

The alerts continue until 9pm on Tuesday, but may well be extended as the hot weather continues.

Meanwhile, the Met Office is considering issuing rare extreme heat warnings ahead of the scorching temperatures forecast later in the week.

Tom said: “We sometimes issue extreme heat warnings, amber and red warnings, which we did back in June, so that’s under consideration at the moment.”
