New weather maps show a huge storm heading over the Atlantic Ocean from Bermuda - bringing the mini-heatwave to an abrupt end.

Warm, sunny conditions will be felt across the UK this weekend, with forecasters expecting high temperatures of 26C in some parts the country on Saturday. It would make it the hottest day of the year so far.

But experts are warning of a return to more "unsettled" weather next week - and radar data shows a fearsome thunderstorm on its way to the UK. The projections, from WXCharts, display a weather front carrying intense rainfall forming in the mid-Atlantic towards the end of the weekend.

This will then divert across the ocean towards the British Isles at the start of next week, with the brunt of the storm making landfall on Tuesday 14 May. This will bring rain to most parts of the UK, including around 2-3mm per hour in areas along the western coast, along with up to 55mph wind gusts.

The Met Office is also expecting a change in the weather outlook from Sunday onwards, due to a developing low-pressure system from the Atlantic. Deputy Chief Meteorologist Tony Wisson said: “Many places will start fine and warm on Sunday, though it is likely to become cloudier from the west or southwest during the day. This will be accompanied by scattered showers, which could be heavy with thunder.

“On Monday we're likely to see more widespread and longer-lived spells of rain, some of which will be heavy and thundery. This will also lead to a much cooler feel to the day.”

In the meantime, Brits should make sure they have enough suncream stored up - as UV levels are expected to be high throughout the weekend. From Friday to Sunday, the forecaster UV level is at 6 in London and the south of England, which is regarded as "high exposure". Moderate exposure is forecast in northern England, Scotland, Wales and Northern Ireland. The Met Office said on X (formerly Twitter) that members of the public should "make sure you stay protected whilst out enjoying the sun", with hayfever patients also warned to prepare for increased amounts of airborne pollen.
