A few days ago, we were delighted to finally be able to count on beautiful spring days, following a long winter and an early spring under the sign of clouds and freshness. Twenty degrees were announced for the end of the week, and all the meteorologists were going in the same direction: spring was finally going to settle in Belgium.
But that was before bad luck got involved. We thought we were dreaming this weekend when we saw the forecast drop from 20 minus ten degrees for Thursday, and a general cooling for the weekend and next week. So what’s going on in the sky? “All this proves that we must always remain very humble when we talk regarding weatherrecognizes Pascal Mormal, meteorologist at the IRM. We had envisaged beautiful days thanks to an anticyclone which still extends as far as Scandinavia, but a “cold drop” phenomenon will reach the country on Thursday.”
what bag “It is in fact pockets of very cold air that will move from northern Europe to our regions. It is unfortunately synonymous with freshness and instability. Thursday will be the most affected day, and we are not going to reach 10 degrees in the center of the countryhe announces. We will perhaps arrive at 12 or 13 degrees on the coast, but it will be cold in the Ardennes. We should not exceed 5 degrees and we can expect light snowfall in places. This cold drop phenomenon is reminiscent of what caused the summer 2021 floods, but we should not panic for the next few days.”
For the following days, the weekend should be quite correct, before another mixed week. “We can hope for 15 or 16 degrees on Saturday and Sunday, but temperatures will drop further from the start of next week. We will stay below the average for the season, with a risk of rain every day, even if the quantities will not be huge.”
Either way, this spring is starting to look furiously like 2021.”It’s not a disaster either, even if we ask ourselves questions, he reassures. The data that is the most negative is not the rain or the temperatures, but the lack of sun. Since January 1, we have only been entitled to 274 hours of sunshine, compared to 340 hours on average. If we stop the calculations at April 16, we are on the sixth least sunny year for 40 yearshe tells us. In terms of temperature, we currently arrive at an average of 8.4 degrees, once morest 9.2 on average. Above all, we always expect the first day at 20 degrees or more. She won’t arrive in the next ten days. It reminds us of 2016, when we had to wait until May 6 to have a spring day. Some years, on the other hand, you are entitled to it from the month of February.”
For the rest, we will therefore have to wait until May to hope to see the return of good weather… “The seasonal models for the end of spring and summer are not changing: we are expecting rather warm weather, with average rainfall. This therefore announces an increased risk of thunderstorms, and a lower risk of drought.”
At least that’s good news…
