The first summer heat is already sweeping Italy, but the worst (or best, depending on your point of view) is yet to come. The temperatures, reports ilmeteo.it, are in fact expected to increase further next week, when there will be a new African blaze with thermal values well beyond the reference climatic averages. The surprises don’t end there, quite the contrary. As the days go by, something new may appear, testifying that Spring is not over yet. To better understand what to expect, as usual, we must broaden our gaze to the entire continental chessboard: well, already by the weekend the arrival of the sub tropical anticyclone, nicely called “Hannibal” will cause temperatures to rise up to around 30 ° C. on the plains of the North. Our focus is on starting next week when we expect a second and more pronounced advance of African high pressure. From Monday 16 May a promontory of the larger sub-cyclone will extend off the Algerian and Tunisian coasts. Saharan supported by very hot air masses and fully summer characteristics. In fact, this particular weather configuration is typical of the month of July (especially in the last 15/20 years) with a sort of anticyclonic block capable of causing prolonged heat waves. This new high pressure pulsation of subtropical origin will have a consequence direct on temperatures that will quickly rise above the average even by 10 ° C. It will be a truly anomalous climatic phase: just think, in this period of the year (mid-May) the average maximum temperatures generally fluctuate around 20/24 ° C in the main Italian cities; if this trend is confirmed, we expect maximum peaks even up to 34/35 ° C (and locally even higher). Favored for this great heat will be the plains of the North and in this case cities such as Turin, Milan and Bologna, as well as the Tyrrhenian sectors of Tuscany and Lazio. The first heat of the season will make the heat even more unbearable: in fact, the warmer air masses within the anticyclone will be charged with high humidity levels in the long journey across the Mediterranean Sea from the Sahara to Italy. ; We remember this condition of physical discomfort and therefore not to be underestimated. Attention however, just as it happens in Summer we do not exclude the possibility of thunderstorms that locally could also be very intense especially in the first part of the week (eyes on Monday 16 and Tuesday 17) on Alpine arc and then especially between Veneto and Friuli Venezia Giulia. On this aspect we will be able to be more precise in the next few days, in order above all to locate the areas most at risk of storms. The weather conditions will remain stable for the rest of the week; however, from Thursday 19 May cooler downward currents from Northern Europe will be able to creep on the eastern edge of the anticyclone favoring a marked drop in temperatures. If we still have a prevalence of sunny weather at least until the weekend, the novelty will concern the thermal values that will return to the reference averages expected in this period. In short, the Spring still does not want to give the definitive step to the Summer.
