The UK is set to bid farewell to its sweltering heatwave, with a dramatic shift in weather expected by the weekend. Temperatures that have soared into the 30s Celsius will plummet as cooler air sweeps in from the Atlantic, bringing relief to communities across all four nations.
Northern Ireland, which has suffered some of its hottest days on record, is forecast to see a significant drop in temperatures, with highs in the low 20s Celsius and lows in the high teens. Similar trends are anticipated across England, where parts of the South East have endured temperatures above 30 degrees Celsius.
The Met Office has issued a yellow warning for thunderstorms covering large areas of England, Scotland, and Wales until Saturday evening. This warns of heavy downpours, lightning, and localised flooding, which could lead to travel disruption and power outages in affected regions.
The change in weather is attributed to a shift in air masses, with cooler Atlantic air pushing in from the west. This will bring lower temperatures, increased rainfall, and stronger winds for many areas. The longer-term forecast suggests a more typical British summer, with a mix of sunshine and showers and temperatures closer to average.
Saturday may still see some lingering warmth in certain parts of England before the cooler air takes hold. Scotland and Wales can expect a similar transition, with thundery showers preceding the cooling. In Northern Ireland, comfortable temperatures are expected to return by the start of next week.
The Met Office advises the public to remain vigilant, especially in areas under thunderstorm warnings. Key safety tips include staying indoors during heavy storms, avoiding open water, and being mindful of slippery roads. Hydration remains crucial, even as temperatures drop, particularly for vulnerable groups. Motorists should also be prepared for challenging driving conditions.
