At this moment there is High Pressure and the weather is improving even where Christmas and Boxing Day showed the last Arctic remnants.
Weather conditions marked by stability will keep us company at least until New Year’s Eve. This is what emerges from the latest mathematical model elaborations. From a thermal point of view, we will certainly see a recovery in maximum temperatures, thanks to abundant sunshine.
Locally, fog will reappear, denser and more persistent in the Po Valley but also in some valley and flat areas of the Center-South.
As for the minimum temperatures, we reiterate what was written previously, namely that thermal inversions will have the task of keeping them low, wintry, with the risk of widespread local frosts. The situation should not change until the very first days of the new year, in this sense some authoritative projections tell us that the weather could start to show some timid signs of change already on New Year’s Eve.
Specifically in the Northwest regions, on the upper Tyrrhenian Sea, and in Sardinia. The change is dictated by a shift of the High Pressure to the west, which could facilitate the insertion of humid air of Atlantic origin with consequent partial destabilization.
Nothing spectacular, although it should be noted that some international calculation centers foresee a much more organized deterioration. Moreover, with a subsequent entry of cold air of polar origin. This deterioration would pave the way for an even more significant change in view of the Epiphany, when the High Pressure could again point towards the north-northeast, causing a substantial Arctic response.
An incursion that would move quickly towards the south-southwest, thus in the direction of the Mediterranean. The Arctic hypothesis for the Epiphany, at the moment, has a good chance of realization because some of the most important and predictive climatic patterns tell us that the action of the Polar Vortex will not be as convincing as in the past.
Those who already take for granted that the High Pressure could prevail are mistaken. Of course, we cannot overlook the anticyclonic hypothesis, that is, that the current structure manages to withstand the assaults coming from the north, postponing the good weather indefinitely.
But at this moment, such a scenario is less likely; if something changes, we will be ready to review our positions in the next weekend updates.
