Milan, 1 January 2022 – Start of the year quasi spring throughout Italy, thanks to high pressure. But in a few days it could change everything: current weather forecasts speak of bad weather with cold, rain and snow. By Tuesday, in fact, in the North we will see a significant one cloud rise: some precipitation will also be possible along the northernmost alpine ridges, in particular between Piedmont and Valle d’Aosta. It should be the avant-garde of a disturbance (the n.1 of January), not intense, destined to slide towards the Centrosud between Wednesday 5 and the Epiphany. This passage on the Peninsula, with still uncertain effects in terms of rainfall, should be accompanied by greater ventilation and an inflow of colder air, with a drop in temperatures towards values more suited to the period. But let’s see the situation in detail.
The hottest New Year in over 100 years. The North African anti-cyclone is the absolute protagonist, accompanied by an extremely mild air mass. According to Antonio Sano ‘, founder of the site ilmeteo.it, “scrolling rapidly through the annals of climatology, it is really difficult to find in the last 100 or 200 years a New Year with such high thermal values at an altitude of 1500 meters: by convention we refer at this altitude in order not to have the influence of thermal inversions and fogs in the
valleys and plains and coasts and to have, all in all, a good representation of the atmosphere in a territory with a complex orography like the Italian one characterized by mountains, hills and valleys “. In our country, the largest thermal anomaly is observed on the Alps, with temperatures even over 10 degrees above the norm and freezing temperatures close to 4000 meters of altitude in the western sector.
Start of the day in the name of fogs, diffuse and even dense especially in the Po Valley and on the upper Adriatic, but also present along the middle Adriatic, in the valleys of the Center, in Lazio, in western Sardinia and in Campania. Low and dense clouds in Liguria and Tuscany, gradually increasing during the day also along the Tyrrhenian coasts of the Peninsula and Sicily; sunnier in the rest of the South and the islands. In the afternoon, temporary and local thinning mists. Outside of the foggy areas in the North, the sky is cloudy to partly cloudy due to the passage of medium-high clouds. After sunset, the mists intensify again on the plains of the north and the middle Adriatic; stalls also in Puglia, Lazio and upper Campania. Temperatures: minimum in without major variations; peaks for the most part slightly down, but still above the norm, with the most marked differences in the mountains and in sunny areas.
On the islands, along the middle Adriatic, in Puglia and on the Ionian sectors of the South time mostly sunny, with local fog in the morning in Puglia, Sardinia and the Adriatic Sea. In Liguria and on the Tyrrhenian side of the Peninsula very cloudy sky, with possible drizzles in the north of Tuscany. Gray skies due to fog and low layers over the Po valley and the coasts of the upper Adriatic; partly sunny on the Alps and Prealps, with passing of cloud at medium-high altitudes. Temperatures: in general still mild and above the norm, they will suffer a drop in the Alps and in the far south, a slight increase in the Po valley, Lazio and Tuscany.
According to the experts of ilmeteo.it, already in the course of Tuesday 4 January a first unstable impulse will result in a worsening of time especially on the Liguria, eastern Piedmont and Lombardy with the risk of some rain. This will be the prelude to one more strong and organized disturbance led by a cold vortex on the Scandinavian sector that will quickly approach Italy. So here it is, on January 5, the real turning pointwith the arrival of cold Bora winds on the upper Adriatic accompanied by intense rainfall on all the Northeast they will hire snow character on the Alps and Prealps starting from 800/900 meters of altitude.
Then the worsening will extend rapidly also to the regions of the Center by Epiphany day, Thursday 6 January. It will be another arm wrestling important between anticyclone and arctic cold, but the erosion action against the high pressure could really go ahead this time. the temperatureare provided in decided decline across Italy due to the entry of decidedly colder currents of arctic origin. So let’s wait a possible weather reversal on Italy. Epiphany all holidays takes away, but this time the anticyclone could also take away. And General Winter could (re) enter.
