A major weather change arrives in Portugal on this date: rain returns with thunderstorms and hail and these are the regions that will be affected

Mainland Portugal will face a significant weather change over the coming days. First, a very hot air mass from North Africa will push temperatures above 40°C on Thursday, September 3rd, especially in the Alentejo region, with some areas reaching 42-43°C. On Friday, the heat begins to decrease in the South but intensifies in the interior North. From Saturday, September 5th, the return of showers, thunderstorms, hail and strong wind gusts is forecast, with greater incidence in the interior of the North and Centre regions, particularly in the areas between Vila Real, Viseu and Guarda. The convective instability results from the combination of hot air at the surface and the arrival of colder air at altitude, which may cause significant lightning discharges. The precipitation distribution will be irregular, with the possibility of heavy intensity in one location and total absence in another.
