This is the only data that seems reliable at the moment. Belgium should remain in the pocket of cold air linked to the polar air which descends on Europe.
On the other hand, the probability of ending up in the “conflict zone” (and therefore of having heavy snowfall) decreases day by day.
The American GFS model, which offers a 10-day (240-hour) forecast, still does not see a delicate situation as of December 18. On the other hand, it suggests the approach of milder Atlantic air over Brittany. We would therefore be in dry and cold weather.
The European model follows somewhat the same scenario with our country still in the fresh air but, still at the December 18 deadline, on the approach of milder air which is rising over France. One can imagine (but these are only conjunctions) that the conflict zone would only approach around December 20 from our vicinity after a period of dry and cold weather.
So far from a disaster scenario.
