We often talk to you about the possibilities of having cold during the winter.
However, while currently Central-Northern Europe is affected by an extremely hot air mass, long-term projections show some significant trends, although still to be confirmed. What emerges is that, in the second half of January, a high pressure similar to those observed in other years could establish itself over Italy, capable of raising temperatures to almost spring-like values.
This could be the first heatwave of 2025.
The duration of this event will be explored further in the article, also because, as highlighted several times, 2025 promises to be extremely variable and very different from 2024, according to mathematical models that process seasonal climate projections. Forecasts indicate that, around the middle of the month and for about a week, a high pressure will establish itself over Italy and Central Mediterranean, extending northwards.
This will lead to a significant increase in temperatures.
Regional differences and climatic peculiarities
Not all of Italy will be affected in the same way.
In the Po Valley, for example, high pressure could generate thermal inversions, with widespread fog and initially persistent cold.
However, with the gradual lifting of the fog, temperatures will also tend to rise here.
Elsewhere, however, weather conditions will be exceptionally favorable, with generally sunny days.
On the coasts, however, a thermal contrast could occur between the incoming warm air and the cooler air, favoring the formation of cloud cover, especially during the coldest hours of the day.
In some locations on the peninsula, temperatures could exceed 68 °F, an extraordinary value for the month of January.
Contrasts with the beginning of the month
This event will be in stark contrast to the weather conditions expected in the first decade of January, when a cold air incursion could bring temperatures in Italy significantly below the seasonal average.
Why the heat in January?
You may wonder why an increase in temperatures in Europe is expected precisely during this period.
The answer lies in global climatic dynamics: the United States of America will likely be affected by an exceptional cold wave, accompanied by snowstorms and epochal low temperatures.
When such extreme events occur in North America, high pressure tends to form in Europe, often a prelude to a climate change.
Towards the end of January, in fact, a further change of scenario could occur, with a return of bad weather in Europe and a significant drop in temperatures.
This could pave the way for a new wave of cold, perhaps even frost, towards the end of the month.
