Despite summer’s arrival, the UK is facing severe weather warnings from the Met Office, with thunderstorms expected across Northern Ireland, western England, and Wales on Thursday, shifting to southeastern England by Friday. Rainfall amounts could reach 30 to 55mm, raising flood risks, while wind gusts may hit 50mph in some areas. Although this summer is predicted to have a higher chance of heatwaves, with average temperatures between 10-17°C, the current forecast indicates continued humidity and rain, particularly in London, which may see temperatures of 27°C on Friday.
