Summer is officially here with temperatures soaring across the country this week.
A hot spell will develop across much of England and Wales with the weather getting warmer from Wednesday onwards.
The Met Office has announced the threshold for a heatwave will most likely be met or exceeded across England and Wales.
Thursday is set to be the hottest day with parts of the UK getting close to 34C.
The weather has caused the Met Office to warn of a level two heat alert for most of England, reports Express.co.uk.
During the day, temperatures are forecast to exceed 30C and at night are expected to reach 15C or above in central, southern and eastern England.
It’s unlikely it will beat the record for the hottest day in June ever, however, which was 35.6C in Southampton in 1976.
Met Office Chief Meteorologist Dan Suri said: “Northern Ireland and Scotland will be under a band of cloud and rain on Monday and Tuesday, however it’ll be dry elsewhere with plenty of warm sunshine and temperatures reaching 28 or 29 Celsius in a few spots on Tuesday.
“Temperatures will continue to climb through the week with a hot spell developing across much of England and Wales.
“From Wednesday temperatures will widely reach into the high twenties Celsius and it’ll be hot across much of the UK, especially central and southern England where we could see highs of 30 to 34 Celsius.
“This hot weather is expected to last until at least Friday and so heatwave conditions are likely to develop for some areas this week.”
According to the Met Office, a heatwave is an extended period of hot weather which is higher than expected for that time of the year and can also be accompanied by high humidity.
A heatwave threshold is achieved when the daily maximum temperatures are met or exceeded for three consecutive days.
