Anomalous heat stops: is the anticyclone over? Weather updates
The anomalies of abnormal heat and African heat that we are experiencing, commonly associated with the subtropical influence of the anticyclone, seem to challenge the seasonal expectations for Winter. Weather projections suggest a possible change in the coming days, although many doubts and fears continue to surround the real extent of the cold season ahead.
In fact, these phenomena, characterized by temperatures above average, raise questions about their duration and the possibility of returning to colder and more typical winter conditions. Seasonal projections frequently indicate a mild and dry Winter, a scenario that, although plausible, cannot yet be considered definitive.
Even though the abnormal heat might seem worrying, it often falls within the normal atmospheric cycles of high pressure that occasionally occur during the cold season.
This type of anticyclone can indeed produce a temporary thermal rise, bringing temperature anomalies especially in the regions of Southern Italy, the Main Islands, and part of Central Italy.
However, for the moment, there is no reason to be alarmed. The current temperature rise therefore seems to be a transitory manifestation, which should continue for a few days in a phenomenon of atmospheric pressure adjustment on a continental scale.
This process is often seen as a favorable condition for the arrival of possible colder changes in the medium term.
In fact, meteorologists are already looking towards next week, when a real climatic shift could occur, bringing cold and perhaps snow at low altitudes. The current seasonal models, which sometimes point towards a mild Winter, should be considered with caution.
Although reliable in general terms, they cannot guarantee with certainty an absence of cold and winter precipitation. High pressure configurations tend to cause drought phases interspersed with waves of abnormal heat, but the European climatic framework is in constant motion, and barometric pressures can suddenly give way to cold currents.
If the current anticyclone were to move, it could open the door to disturbances from the northeast, a condition that would favor a thermal drop even in Italy. The current thermal anomalies are therefore the result of an expanding subtropical anticyclone towards the north, capable of transporting warm air over many Italian areas.
This configuration causes temperatures above average, with a climate that almost resembles spring in the middle of December. The most affected regions are Southern Italy, the Main Islands such as Sicily and Sardinia, but also areas of Central Italy and, in some circumstances, Northern Italy.
In these areas, the maximum temperatures can record exceptional values for the season, creating a warm spell that, however, is not entirely unusual during winter anticyclonic phases. In the coming weeks, it will be crucial to follow the possible change in atmospheric currents.
A well-established high pressure configuration over Western Europe could facilitate the descent of cold air from the northeastern quadrants.
In this case, a wave of cold could finally break into Italy, leading to a thermal drop and the possibility of snow in mountainous areas and perhaps even at low altitudes.
This dynamic could occur with the weakening of the subtropical anticyclone, allowing the entry of cold disturbances. Despite the possible continuation of abnormal temperatures, the weather scenario remains uncertain and can evolve rapidly.
The approach of the end of the month could coincide with new incursions of cold air from Northern Europe, a phenomenon that would break the anticyclonic dominance.
These impulses could bring genuine winter cold to the Alps and the Apennines, especially in Northern Italy and the inland areas of Central Italy.
The temperature drop linked to polar-origin disturbances would favor the fall of snow even at hilly altitudes, marking the arrival of the first truly winter phase. For now, despite above-average temperatures, the abnormal heat should not be interpreted as a definitive signal for Winter. The current atmospheric dynamics seem to indicate rather a temporary anomaly, part of a broader barometric redistribution on a continental scale.
