Just a month ago we witnessed the end of one of the most intense summer heat waves. The weather forecastwhich up to that point had brought exceptional temperatures and few episodes of refreshment – the most notable around Mid-August – seemed to finally be moving towards a change. High temperatures had characterized much of July e Augustmaking summer particularly unbearable. However, already from the first days of Septemberthe meteorological picture began to change.
The heat remained predominant until the beginning of Septemberbut the signs of a change were increasingly evident. The weather forecast showed clear turbulence, heralding a change that would end the dominance of the African anticyclone. In fact, weather forecasts had long anticipated the arrival of an arctic irruption, an event that would have brought strong changes in temperatures. temperature and more unstable weather conditions.
The entry of cold currents marked the start of an early meteorological autumn. In particular, the regions a Northern Italy they were the first to suffer the influence of the cold air, with a lowering of temperature and an increase in precipitation. September therefore saw a clear reversal of the trend, with episodes of rain widespread and a drop in temperature compared to seasonal averages.
Autumn in command
The arrival of meteorological autumn has also had notable repercussions on Central Italy and in Southern Italywhere the decline in temperature was accompanied by extreme phenomena, such as violent thunderstorms and hailstorms. In some areas, such asEmilia Romagnaheavy rainfall caused significant disruption and damage. The beginning of September therefore confirmed that the worsening was much more serious than expected.
Weather forecast share weekend
When it seemed that a temporary anticyclonic stability could improve the situation, the weather forecast it gets worse again. The forecast for the last weekend of September indicate a new atmospheric failure, with the arrival of a depression coming from Northern Europe which will heavily affect the basin of Mediterranean.
This worsening will be rapid, but the effects will be felt intensely. The risk of phenomena extremes is once again concrete: violent storms, storms, hailstorms and strong gusts of wind are expected in several Italian regions. The weather forecasts indicate that, even if the depression will not be as intense as that of the beginning of the month, its impact will still be significant, especially on the regions of Northern Italy and along the Apennine ridge.
Projections for the following days remain uncertain, with many weather models showing significant divergences. What is certain is that the last weekend of September will be characterized by unstable and potentially dangerous weather conditions.
