The weather forecasts for the time around Christmas show a complex and uncertain scenario characterized by possible radical changes in weather conditions.
Currently the meteorological picture is characterized by a period of local severe weather in some regions, but a gradual improvement is expected over the weekend, leading to greater stability. This stability is achieved by the return of the Subtropical anticyclone favored that the weather events in Italy should dominate next week.
His arrival will mark a significant increase The temperature with the transition from the intense cold of the last few days to a significantly milder climate, especially in the midday hours.
Temperature increases could locally reach +10°C above seasonal averages and be significant positive temperature anomalies in many regions, from North of Italy über Central Italy up to some areas in South of Italygenerate. Despite the milder temperatures during the day, the night hours will continue to be characterized by cold weather, favored by the temperature inversions typical of this time of year when the nights are particularly long.
Under these conditions it will spread too Frost in the plains and in the valleys come during the Fog will show stubbornness, especially in the Po plain and in the inner areas of Central Italy. However, the dominance of the high pressure area could the weekend before Christmas significantly weaken and pave the way for worsening weather conditions.
The currently available mathematical models suggest the possibility of subsidence of the North Atlantic low-pressure flow, resulting in the formation of a cyclonic wave in the central Mediterranean could lead.
This change could bring a significant deterioration in the weather with the arrival of intense phenomena.
According to some forecasts, a… secondary cyclone develop that is fed by the heat stored in the oceans.
This scenario would the emergence of strong thermal contrasts favor, with the risk of violent thunderstorms, Hagel und möglichen snowfall at medium to low altitudes in the northern regions. The development of weather conditions in the days around Christmas remains uncertain.
If the deterioration described above actually occurs, a problem could occur baric gap in the central Mediterranean, which could attract further supply of cyclonic air.
In this context, the arrival of cold air masses is maritime polar or even arctic Origins that could reinforce the winter character of the Christmas season cannot be ruled out. Under these conditions could Snowfall occur at relatively low altitudes, especially in the North of Italy and in some areas of Central Italy. However, it could African anticyclonewhich is known for its persistence, will once again influence the meteorological picture.
A recurrence immediately after the pre-Christmas deterioration is not ruled out, which would result in a restoration of more stable conditions and temperatures above the seasonal average.
The weather dynamics therefore remain strongly dependent on the interaction between the Atlantic low pressure areas and the resistance of the high pressure area, with the possibility extreme phenomena wie intense thunderstorms, heavy snowfalls or even abnormal heat waves to experience.
The next updates will be crucial to understand whether Christmas will be characterized by typical winter weather or whether a milder and drier configuration will prevail.
