Brits will be basking in 24C sunshine today and it’s getting warmer – but the date when thunderstorms will hit has yet to be determined.
The Met Office is forecasting a warm run for the weekend before a wet wave of weather sweeps in from the west.
The cloudy start of this morning is expected to result in extended sunny spells in many areas.
Highs of 24°C are planned for this afternoon, rising to 26°C tomorrow as the sun clears the night’s fog.
Some wind is forecast for the extreme northeast, but meteorologists say it will ease as the day progresses.
However, rain showers are expected on Friday afternoon, indicating a shift towards wetter conditions.
Then on Saturday thunderclouds will gather, in parts of Scotland there will be rainfall of up to 32 mm per hour.
The worst of the weather is expected to be concentrated in the northwest, but heavier rain could hit southern areas later in the day.
The Met forecast for the weekend reads: “It will be cooler and more restless from Friday, with heavy rain showers possible on Saturday.”
“Rain will continue on Sunday, but there will be some dry spells in the south-east.”
Looking ahead, the long-term forecast suggests the weather will be “more volatile” next week, with some “heavy and heavy” showers across the country.
The forecast adds: “The western regions are likely to experience the greatest rainfall, but drier and brighter conditions are possible in the southeast.” England have the greatest chance of doing so.
“It’s generally windy across the country and temperatures are in line with annual averages for many, perhaps slightly below in wet or windy conditions.”
This trend should continue towards the end of the month in the UK, capping a wet and windy summer.
