Thunderstorms arriving in the North, hail alarms and supercells: the areas at risk

A new storm front is arriving in Northern Italy on Friday 24 June. This time Lombardy will be affected by strong storms not only in the Alpine and pre-Alpine belt, but also in the plains, with the risk of winds of over 100 km / h and large hail for the province of Brescia, especially in the western sector.

After a long time, an intense wave of cold air will thus enter the Po Valley causing a violent thunderstorm passage: “The energy will be truly remarkable, with values ​​above 1900-2000J / kg and the shear (variation of intensity and wind direction with altitude) will be really high especially on central eastern Piedmont and Friuli-Venezia Giulia, with the possibility of very violent supercells. Probable squall line evolution (band of storms with a continuous gust front, ed) or multicell in Lombardy “, explain the ZenaStormChaser experts.

“Storm phenomena that will develop in the west, in the Alps starting from 14-15 and then evolve rapidly towards the east – we read on ZenaStormChaser -. In the area marked with level 2, but especially 3, very organized supercells are likely with large hail (5-6cm) and downburst with winds above 110km / h (pay close attention) “.

In Lombardy, thunderstorms will appear around 17-18, changing into an intense multicell or squall line: “This does not mean we will have to let our guard down – conclude the meteorologists of ZenaStormChaser -, however, very strong downbursts, hailstorms and possible flooding will be probable. In the area with level 3 there is a risk of tornadoes “.
