In the south of the country, temperatures will occasionally rise to almost 10 degrees! “The snow that has fallen will thus melt in a series of regions, south of the Sambre-et-Meuse furrow. North of this limit, we will keep temperatures around 0 to 2 degrees, and it is in this zone between Namur and Brussels and between Tournai and the Campine that the snow potential will be the most interesting, in the second part of the evening.”
The snow cover should therefore be thicker in Brabant, for example, than in the Ardennes. “We could have between 5 and 10 centimeters of snow in these regions, especially above 100 meters of altitude. The north of the province of Liège will also be affected, as well as the Hautes-Fagnes. In the south of the country, the cold will also return during the night, with further snowfall, until Thursday morning.”
A complicated morning on the roads, Thursday
On Thursday morning, snow showers are still expected, which will probably complicate the situation on the roads. “In fact, the snowy area will be located a little further north than expected, but the situation remains difficult to envisage with this conflict of air masses, and mild air which remains in ambush a few hundred kilometers away. For example , there will be very little snow on the ground in Gaume, while we will certainly reach 25 to 30 centimeters at the Botrange signal. There were still 11 centimeters of snow this Wednesday, and the layer will therefore thicken.
In the center of the country, we can expect a slight melting in the morning, but the afternoon will be cooler. “We will find drier conditions on Thursday afternoon, but also colder. What will be notable about this snowy episode – we have still had a few since November – is that it will not will not be followed by a significant mild spell which will wash away the snow almost everywhere. For the first time this winter, it is the polar air which should win the game, with a winter period of around ten days over the region. the whole country will barely exceed zero degrees. during the day until the beginning of next week, before returning to seasonal temperatures at the end of the week. A good part of the snow will therefore hold until the beginning of next week, including in the center of the region. country. The nights will be cold, with -5 to -10 degrees in the coming days,” explains Pascal Mormal.
The good news is that after Thursday, we will return to much more stable and fairly sunny weather. We will be able to enjoy beautiful winter walks and the brightness that we have really missed in recent weeks!
