Bad December due to weather conditions from one extreme to the other

We have very carefully observed i seasonal mathematical models and today we want to try to clarify in a simple and concise way what the conditions could be Weather forecast for the month of December.

Obviously, a whole series of variables must be taken into account, such as the state of the Polar Vortex, the QBO, La Niña and so. But it must be said that these issues are, let’s say, “specific”. They are arguments that presuppose a certain knowledge of the subject, it means that you have to know some terms and we know very well that the reader is more interested in knowing what the result of certain combinations could be.

So, leaving aside the overly technical details and such, let’s get straight to the point. How could December be presented? So let’s say you could offer us two distinctly different phases. First, which can be located roughly in the first decade or even the first two weeks, could be quite lively. Let’s say dynamic, let’s say even extreme.

Could pass frequent bouts of depression, both from the North Atlantic and the Arctic. Cold then, just to be concise. Cold and bad weather, so there could be several occasions of locally abundant rains and that, due to temperatures below the seasonal average, could acquire a snowy character at low altitude. We are talking about mountainous actions, it does not matter if they are low, medium or high hills. These are details that we cannot provide you at this time. It is equally obvious that the use of the conditional is essential., let’s remember that we are reasoning in probabilistic terms, not in terms of absolute certainties.

The second half of the month instead, it could take us to other extremes. This time the anticyclonic extremes, that is to say, the High Pressure, could strongly take over the scene, determining a stabilization of the climatic conditions and as always a significant increase in temperatures. Christmas? Well, at this point we could hypothesize yet another Christmas in the name of a stable climate.

Even in this case, however, we do not exclude that there may be some deviation from the rule. We cannot exclude some other depression, always of the North Atlantic matrix. But the odds should decrease significantly at this stage. Let’s say, in conclusion, it could be a two speed december: first in fifth gear, then with the parking brake on.

We remind you that weather forecasts valid for up to 5 days are more reliable, while this decreases as we move further in time.
