The UK is bracing itself for a drenched weekend as the Met Office issues a warning of heavy rain and thunderstorms across large parts of the country. As of 15 July 2026, forecasters are advising people to prepare for potentially disruptive weather conditions that could impact travel and outdoor activities.
England's South West and Midlands regions are expected to bear the brunt of the downpour, with substantial rainfall and frequent lightning anticipated throughout the weekend. Temperatures in these areas may struggle to reach 18°C, a significant drop from recent mild conditions. Northern England and parts of the East will also experience heavy rain, though perhaps not as intense as southern regions. Wind speeds could reach up to 25 mph in exposed areas, exacerbating the unpleasant conditions.
Scotland is set for a wet weekend, with persistent rain forecast for the Central Belt and southern Highlands. While thunderstorms might be less prevalent than in England, the sheer volume of rain poses a risk of surface water flooding. Northern Scotland may see a slightly drier picture, but still with a risk of showers. Temperatures across Scotland are expected to remain in the low to mid-teens.
Wales is forecast to experience widespread heavy rain and a high likelihood of thunderstorms throughout Saturday and Sunday. The Met Office has highlighted the potential for localised flooding, particularly in urban areas and low-lying ground. Temperatures in Wales are predicted to be around 16-17°C, accompanied by moderate winds of up to 20 mph.
Northern Ireland will also experience a significant amount of rain and some embedded thunderstorms, with similar temperature ranges and wind speeds, increasing the risk of difficult driving conditions. The Met Office advises people to take precautions, such as checking flood warnings, allowing extra time for journeys, and securing outdoor items. Drivers should be particularly vigilant for standing water and reduced visibility.
