Weather: November, possible an autumn turn ahead of schedule, now there is a date, the details

Return of autumn after the All Saints’ BridgeA turning point is in sight. If the African anticyclone will continue to affect the weather in Italy also in the next few days, it could however suffer a failure earlier than expected compared to what the Computing Centers feared in previous updates: time could get worse immediately after the Ponte di Ognissanti with a return of the rains.
This could open a period of clear autumnal mold with bad weather conditions in many regions (especially in the North and in part of the Center), but above all with a gradual drop in temperatures, which would thus return to the averages of the period within a few days.

According to the latest maps at our disposal a general weather change it will be possible around 3/4 Novemberwith the approach of a series of perturbed North Atlantic impulses capable of favoring an erosion of the powerful anticyclonic nucleus which at this moment protects us, day after day.
The high pressure could rise towards high latitudes (even reaching as far as Greenland) thus leaving free space at the entrance of a disturbance downhill on France and Italy, supported by colder air of polar-maritime origin. This is one of the most significant weather configurations in terms of bad weather in Italy (visible on the attached map).
There fall of anticyclonic balloon“would kick off a favorable period for rains, with bad weather and temperatures certainly more suited to the period. However, only in the next few days will it be possible to deepen the question, better assessing whether or not this potential wound on the Mediterranean will be able to open the gates of the Atlantic, definitively setting the stage for the autumn season.

If the worsening does not go through, the situation will become nothing short of dramatic, especially from the point of view of the lack of rainfall (drought), which risks having repercussions in the long term. Without the autumn rainfall (those that bring the great snowfalls on the Alps and the abundant phenomena in the plains), you risk being catapulted into a water crisis nationwide. Already in the summer just passed, many Italian municipalities found themselves without water (not only irrigation, but also drinking water). A real drama that is likely to be relived in an even more widespread way in the next summer.

This is a long-term projection, with large margins of uncertainty, but something is starting to move.
