Spring continues to have many connotations dynamic And turbulentespecially in this one first ten days of May. Showers And temporal they will still be undisputed protagonists during the next weekdue to the arrival of another depression quite insidious.
All the mathematical models they agree on the arrival of one cold drop in high altitude who will set out from Great Britainthrowing himself fully into the Mediterraneanwhere it will persist for several consecutive days. Also, this cold core will be able to call back colder air fromEastern Europe which will invade everything Italy favoring a sudden drop in temperatures especially starting from Tuesday 7 May.
All this fresh air will naturally not go unnoticed and produce a lot of instabilityespecially the typical ones afternoon thunderstorms And evening which represent a classic of late spring and of thesummer. The daytime sunshine allows a constant accumulation of power in the low layerswhich is then crucial for the formation of temporal, showers And hailstorms when it passes colder air in high altitude.
These strong thermal contrasts will be reality during the next weekespecially starting from Tuesday 7 May. Temporal And showers will be protagonists on a large part ofItaly from North to southbut locally we will also deal with rather extreme phenomena as strong storms, hail large in size and intense gusts of wind. These intense phenomena and locally harmful will be the result of the flow of the cold core in high altitudewhich he will present temperatures close to -26° about 5000 m of altitude. The strong temperature gap will be crucial for the development of intense convective motions which will drag them upwards at great speed warmer currents And humid present in low layers. Thus i temporal they could become very intense and give rise to hailstorms with medium or large grains and also rain in character storm.
These more intense phenomena will be more likely in internal areasfrom the Po Valley to the extreme south. It was today is totals expected during the next week that show us so much instability which will hit our boot on several occasions.
