Holy Week and Easter Monday divided by faint glimpses of spring in a context of rain and storms due to high pressures that limp to say the least and are not capable of guaranteeing a period of calm and lasting weather.
The risk therefore increases that Atlantic disturbances will also find a “clear” path to the Mediterranean and Italy during the Easter period.
The cause must be sought in powerful atmospheric movements of air masses. on a hemispheric scale scheduled for the end of the month. In technical terms these immense atmospheric maneuvers are defined as “meridian exchanges“: L’Cold air descends towards the mid-latitudes from northern Europe/Atlantic, cooling them, while the warm African subtropical air (african anticyclone) rises towards Europe.
Italy, and in particular the Central-North regions, risks finding itself in a kind of “convergence zone” in which these important meteorological figures interact.
Precisely in this “no man’s land” the contrasts greater and more insidious: the heat that accumulates in the lower layers of the atmosphere increases the risk of extreme weather events like downpours and hailstorms. In essence, we could face one series of cold, unstable high-altitude forays capable of significantly destabilizing the atmosphere, causing rains and storms.
According to the latest updates available to us, since the day of Easter (Sunday, March 31) the step of one atlantic disturbance could cause an explosion, even sudden, of temporarylocally also intense, especially at North It’s in Tyrrhenian side. As usually happens in spring, this does not mean that the entire day is ruined by the rain, on the contrary: this type of phenomenon lasts a few hours at most, before the sun returns (in short, it is the classic spring instability). ). In the south and on the two main islands, the possibility of the first heat explosions cannot even be ruled out, with maximum temperatures that could reach 30°C.
From a thermal point of view, a moderate decrease cannot be ruled out, with temperatures likely to fall a few degrees below the reference averages.
