Heatwave on way back to Sussex for one day and then more rain with unsettled weather
The heatwave is promising to come back – but don’t discard the umbrellas just yet, as it is only here to stay for a day.
A level two heatwave warning was issued yesterday for tomorrow, when temperatures are set to reach 30C.
A yellow rain warning has also been issued for Friday and Saturday, when up to 30mm of rain may fall in an hour.
A Met Office spokeswoman said: “Temperatures are expected to peak in some southern and eastern areas on Thursday, with a humid feel and a warm and muggy night on Thursday night.”
While temperatures will soar tomorrow, showers are predicted on Friday afternoon, when temperatures will drop back to 20C. The Met Office has issued a yellow warning of rain following concerns that 30mm of rain may fall in an hour.
Into the weekend, temperatures are likely to stay around 18C, with overnight thunderstorms on Saturday night.
The Met Office believes the changeable conditions may persist for much of August.
A Spanish plume is thought to be responsible for the weather tomorrow.
Met Office meteorologist Ewen McCallum said: “Spanish Plume is actually a catchy name for a rather complex meteorological phenomenon which leads to warm conditions and heavy showers or thunderstorms over parts of the UK and north-west Europe.
“As the name suggests it is a plume of very warm air that pushes north from the Spanish plateau and reaches the British Isles on a southerly airflow.
“Of course over the UK we are normally affected by much cooler Atlantic air as cold fronts encroach from the west.
Now when these two air masses meet, the very warm plume air is forced to rise vigorously over the cooler Atlantic air and as a result produces thunderstorms.
“Because these features can cover large areas the storms are often grouped together and can give widespread, heavy rainfall, often accompanied by hail.”
A level two heatwave warning is triggered as soon as the risk is 60% or above for threshold temperatures being reached in one or more regions on at least two consecutive days and the intervening night.
The Met Office said this is an important stage for social and healthcare services who will be working to ensure readiness and swift action to reduce harm from a potential heatwave.
