After a rainy start in the morning, it will be drier with clear spells on Saturday. During the day, the chance of showers – especially in the south – increases again and there may even be thunderstorms. The mercury goes up to 12 degrees in the Ardennes and 18 degrees in Flanders. A strong wind blows at sea with peaks of up to 55 kilometers per hour. That is what the RMI says.
