The latest projections confirm a stormy weather change over the course of next week, which will interrupt the excessive heat of Summer 2024.
In short, an organized perturbation front should pass through capable of paving the way for cool North Atlantic air.
This shake-up, unlike the one that occurred shortly after mid-August, should manage to deal a blow to the scorching August Summer. Essentially, nothing will be the same as before, even though Summer will probably not be over and will continue to accompany us through September. The moment of this change is expected over the course of next week, starting from September 3-4 when the African anticyclone will be forced to retreat.
An intense perturbation, driven by a cyclone between Iceland and Scandinavia, will manage to reach Italy starting from the North. Thus, a stormy deterioration will begin, certainly heightened by the presence of very hot and humid pre-existing air that will act as fuel for the perturbation system.
Therefore, violent thunderstorms, with hail and violent but localized downpours, cannot be ruled out.
The decline of Summer, with the African heat being ousted in the first week of September
It is worth noting the possibility of the genesis of a vortex at all levels passing over the Mediterranean and further fueled by the warm sea waters. If this trajectory is confirmed, there could be conditions for an end-of-Summer storm. The most striking aspect will be the drop in temperatures, as the perturbation will be accompanied by a significant influx of cool North Atlantic air.
These currents will spread over Italy, flowing from the Rhone Valley and quickly displacing the African heat. The stormy air exchange, combined with the declining solar radiation and the lengthening of the dark hours, will help project us into that long-awaited seasonal change. This does not mean that Autumn will arrive suddenly, but there may no longer be room for such intense and persistent heat. We will thus begin to put aside the scorching heat and truly sense a decline of Summer.
Temperatures could drop by 10 degrees or more, bringing us back to significantly more normal values.
The heat could then return, but in a probably more bearable context.
