Rain, wind and cold, won’t May be like this too? Let’s clarify

Endless rain, wind and cold: isn’t May May going to be like this now too?

Before delving into any explanation, a necessary premise must be made. The medium and long term trends they serve to provide a general and summary idea of ​​precipitation and temperatures on a large scale and should not be understood as classic weather forecasts, useful for planning events in one’s daily life. Nonetheless, thanks to scientific progress, seasonal projections have now become a valid scientific prognosis toolwith decisive contributions in longer-term climate assessment.

But let’s get to our topic. According to the latest updates, with the beginning of May temperatures will rise above averagewith deviations from the reference values ​​of even +1/3°C over a large part of the Mediterranean basin. As the map below shows, at the moment the heaviest and therefore warmest anomalies would seem to affect the Centre-South thanks to the presence of a persistent and constant area of ​​high pressure.

The most interesting news concerns the general trend on rainfall. In fact, it seems that this trend aimed at rainfall surplus in place for more than a month now. The map below highlights in color green the areas they might have more rain than normal: in this case the regions of the North West and those on the Tyrrhenian side would be most affected. This could all be caused by powerful meridian exchangesas has already happened in recent weeks: these are abrupt and rapid changes in the weather with late cold waves descending directly from the North Pole.
The danger, determined by the contrasts between abnormal heat and sudden late cold outbreaks, should not be underestimated: extreme phenomena are increasingly frequent in Italy too, especially during the spring season, such as violent thunderstorms (even with hail), tornadoes or storms.
Also May it could follow this climatic trend, with thermal values ​​well above average and even with summer-like flares of heat capable of causing us to even exceed 30°C in the event of the advances of the fearsome African anticyclone.
So hot, but watch out for thunderstorms!
