Sunday afternoon, the weather remains sunny with, mainly in the west, the possibility of some high sails, announces the Royal Meteorological Institute (IRM) in its midday bulletin. The maxima will range between 14 and 16 degrees in the Ardennes and will reach values of 18 or 19 degrees in the plains or even locally 20 degrees.
On Sunday evening and in the night from Sunday to Monday, the sky will again be clear within a few veils of altitude in the eastern half of the country while in the west the clouds would have increased more. The minima will drop between 1 and 4 degrees in the Ardennes, sometimes even below 0 degrees in certain Ardennes valleys and from 4 to 7 degrees in Lower Belgium.
For Easter Monday, the sun will be gradually obscured by high then medium cloud banks, which will thicken especially over the west of the country in the late afternoon, but the weather will remain dry. The maxima will vary between 14 degrees on the peaks of the Ardennes and 19 or locally 20 degrees in the center.
On Tuesday, medium and high altitude clouds will mainly be present over Belgium. More cumuliform clouds will still appear as the hours go by but the weather will remain dry except for a few isolated light showers. The risk of precipitation will be a little more marked in regions close to France. The maximum will be between 13 or 14 degrees in the Hautes Fagnes and at the sea, and 18 or 19 degrees in the center.
From Wednesday to Friday, the IRM predicts alternating periods of sunshine with cloudy fields and generally dry weather. The maximum will be close to 16 or 17 degrees in the center of the country.
