Tonight, snowfalls are possible in the east, followed by periodic clear skies in the west and centre. South of the Sambre-et-Meuse, low clouds will persist, and may reduce visibility locally. Frost throughout, with temperatures between -2 degrees to the west and -5 or less on the snowy Ardennes. The wind, moderate at first, will shift from NW to SW, and will weaken, especially along the French border.
On Tuesday, the weather will be drier, but possible snow at night.
