The Royal Meteorological Institute (RMI) announced its latest weather forecast in its midday bulletin on Thursday.
Showers will mainly affect the south-eastern half of the country and may be accompanied by thunderstorms and gusts of wind of up to 70 km/h or slightly more.
Brussels is forecast to be passed by the cloud movement, potentially having the chance for its own showers at around 16:00, possible before.
At the same time, the maximum temperatures will range from 23°C to 24°C by the coast up to 33°C in the east.
While the rest of the week is expected to have relatively mild weather, very high temperatures are likely to return on Monday with highs of 35°C and thunderstorms during the night.
