The extensive low-pressure circulation with its driving center between Ireland, the Bay of Biscay and Portugal, continues to convey humid and unstable air masses towards Northern Italy, which is associated with widespread, intense and sometimes persistent precipitation close to of the Alpine reliefs.
The rains of the last few hours
“In the upper Piedmont in the last 48 hours, as expected, very significant rainfall accumulations close to 200 millimeters have been recorded, especially on the VCO, with local hydrogeological criticalities and swelling of rivers and streams, albeit without flooding as happened yesterday in the nearby Lombardy, between the provinces of Milan and Monza-Brianza – explains meteorologist Andrea Vuolo – The hydrometric level of Lake Maggiore, specially observed in recent days, still remains below the warning threshold on the Piedmontese shore, with a height of 4.8m according to the latest Arpa Piemonte survey at the Verbania – Pallanza hydrometer.
Rain showers are currently still ongoing in the foothills and high western and northern plains of our Piedmont, while there is a temporary drier pause on the eastern plains. However, during the afternoon-evening, new showers and thunderstorms will form again in the Alpine areas from Cuneo to Biella, subsequently extending by the evening – of a scattered nature – also to the plains, with once again intense phenomena and with snow levels generally above 1,800 -2,100 meters.
“Illusionary” weekend
A few more sunny spells are expected between tomorrow and the weekend, together with a general rise in temperatures which will reach 20-22°C, but with possible late afternoon and evening showers and thunderstorms which may occur from the medium-low mountain sectors. extend to the plains, especially between Cuneese, Torinese, Canavese, northern Asti, Biellese, upper Vercellese, Novarese and VCO, locally accompanied by hailstorms and gusts of wind. More sunny spaces on Sunday, with maximum temperatures up to 22-24°C, but a new very unstable phase seems likely at the beginning of the new week, especially between Tuesday and Wednesday, with more widespread rains again together with a new drop in temperatures.
It is highly probable that even for the entire third decade of May the weather conditions in Piedmont may remain rather lively and with frequent rain, together with temperatures that will remain around or below the averages for the period”.
