TORINO – The region of Piemonte has recently faced a series of intense thunderstorms and hail, marking a notable weather pattern for early May. According to the latest forecasts from Arpa Piemonte, the area is currently situated within a large low-pressure zone, which is expected to bring weak, humid, and unstable weather conditions from May 9, 2025, through the beginning of the following week.
On the afternoon of May 9, residents can expect unstable conditions with showers and potentially strong thunderstorms, particularly in the western and southwestern alpine regions. These storms are likely to produce small hail as they move slowly onto the plains. Weather phenomena are expected to diminish by the evening of May 9, providing a brief respite.
Looking ahead to Saturday, May 10, forecasts indicate that showers and thunderstorms will persist, especially in the mountainous areas. However, the plains will primarily experience only weak, scattered showers. As the weekend progresses, conditions will further stabilize from Saturday evening through Sunday morning, May 11, when a resurgence of thunderstorm activity is anticipated, particularly starting from the Cuneese and lower Torinese regions, before extending throughout Piemonte.
According to Datameteo experts, the mild low-pressure systems over the Mediterranean will continue to maintain an unstable atmosphere, with temperatures forecasted to remain below the seasonal average. In Turin, the sky will be irregularly cloudy until Sunday, with showers and thunderstorms expected mainly in the western and northern sectors, particularly between the afternoon and evening hours. Temporary clearings may occur, especially on Sunday when convective activity is projected to diminish compared to the previous days.
Temperatures in Turin are expected to rise slightly over the weekend, with maximums reaching 21-22 °C by Sunday. Minimum temperatures are also set to increase, hovering around 12-13 °C. Winds will generally be weak and variable, although strong gusts may accompany thunderstorms.
As the weekend wraps up, the weather outlook for Monday, May 12, indicates another phase of instability, with no organized bad weather predicted. Instead, irregular weather patterns will continue, making forecasting challenging at least until Wednesday, May 14.
After a morning characterized by intermittent rains and even snowfall at elevations below 1,500 meters in northern Piemonte, a partial improvement in weather conditions is anticipated. By the evening of May 9, the region is expected to dry out after the last showers and thunderstorms impact the Alps and the nearby foothills.
Manuel Mazzoleni from 3bmeteo provided insights into the upcoming weekend weather, stating, "Saturday will be variable, with frequent passing clouds and local showers in the morning, especially over the West Alps and in the Torino area. In the afternoon, showers and thunderstorms will concentrate on the central-southern Alps and the Apennines, with possible encroachment into the Cuneese region."
As for Sunday, Mazzoleni added, "The weather will improve, especially in the first part of the day, but new showers and thunderstorms are expected in the afternoon between the western Alps and the northern Apennines, with evening encroachments on the southern and western plains."
Residents should remain vigilant as conditions may change rapidly, particularly with the threat of thunderstorms persisting through the weekend. No area is entirely exempt from the risk of precipitation, underscoring the unpredictable nature of the weather during this period.
Overall, the weather in Piemonte for the upcoming days will reflect a blend of instability and sporadic improvements, with temperatures gradually rising but remaining below the seasonal norms. Those planning outdoor activities should be prepared for sudden changes and potential thunderstorms.
As the region navigates through this tumultuous weather pattern, it serves as a reminder of the dynamic nature of springtime in Piemonte, where conditions can shift dramatically within hours. Local meteorological services will continue to monitor the situation closely, providing updates as necessary to keep residents informed.
