Belgium's weather agency revises Saturday forecast upwards amid heatwave

Belgium is bracing for another day of intense heat on Saturday, with the Royal Meteorological Institute (IRM) revising its forecast upwards. While Friday marked the peak of the current heatwave, Saturday could still bring temperatures as high as 39°C (102.2°F) in eastern parts of the country.

The IRM predicts that while some morning thunderstorms might affect western regions, the day will largely remain dry but very hot and humid. Coastal areas will offer some respite, with temperatures around 26-27°C. The eastern regions, particularly the Campine area north of the Liège province, are expected to experience the most oppressive heat.

Thunderstorms are anticipated nationwide from Saturday evening. These could be locally intense, accompanied by hail and strong gusts of wind. The night from Saturday to Sunday may see another wave of stormy showers, again with the possibility of hail and strong winds. Overnight temperatures are expected to remain high, between 19°C and 24°C, making for an uncomfortable night.

The situation is expected to improve by Sunday evening, with temperatures gradually becoming more breathable, ranging from 24°C to 30°C across the country. However, the eastern parts of Belgium will likely continue to experience warmer conditions.
