Anticyclone of Halloween with sun and anomalous heat for the period over most of Europe. Last days of October with a summer flavor. We will have to rewrite the calendar without the mid-seasons or rather without some seasons: from April to October summer, from November to March autumn. In recent years the winter frosts in the city have disappeared and, unfortunately, often also the perennial snow in the mountains. There are no more winter and spring. And we go towards the hottest Halloween in history, with maximum temperatures over 30 ° C in Italy and Spain, even up to 35 ° C in Andalusia. Mattia Gussoni, meteorologist of the site www.iLMeteo.it, confirms that the climate has changed dramatically. With this super hot climate, as soon as a perturbation on the Mediterranean enters, we will risk violent phenomena: on the horizon the meteorological models see a possible deterioration from the middle of next week. We will have to be careful of potential storms along the coasts (the sea is still warm with a positive anomaly up to + 4 ° C in the Western Mediterranean and along the southern Italian coasts); but we will also have to pay attention to the persistent classic autumn rains that will fall on very dry ground: as we know, when the rain arrives on dry soils, the infiltration is less and there is a risk of total runoff. In other words, all the water that rains ends up in the rivers immediately, creating rapid flood waves that are very dangerous. Heavy rain is expected on Thursday 3 and Friday 4 in the North and on part of the Center. IN DETAIL Saturday 29. In the North: sun and summer-like heat. In the center: sun and abnormal heat. In the south: good weather and summer climate. Sunday 30. In the north: local mists on the plains partially dissolving during the day, sun and heat in the mountains and along the coasts. In the center: sun and heat except for night mists in the internal valley bottoms. South: prevailing sun and summer climate. Monday 31. In the north: partly rising clouds in the North-West, sun elsewhere. In the center: sun and heat except for night mists in the internal valley bottoms. South: prevailing sun and summer climate. Trend: gradual subsidence of high pressure from mid-week with rains starting from the North and extending to the Center. Probable deterioration also in the South from Friday.
