The skies will be covered tonight, starting with the coast, and a band of rainfall will move across the country from west to east. The temperature will be fairly cool, with lows between 9 and 12 degrees in the Ardennes, and between 13 and 15 degrees in the plains.
As the disturbance moves across the country, the wind in the southwest sector will pick up speed, becoming high as it moves inland and very high, even stormy, along the coast. Expect gusts of up to 80 km/h inland and even as high as 100 km/h at sea.

In the north, the weather will be variable, alternating between showers and clear skies. In the afternoon, the rain front will shift southward and the entire country will experience some showers, but also sunny periods.
