More storms and general cooling

Source Summary

The passage of an upper trough has changed the weather in recent hours. Thunderstorms have discharged intensely due to the generation of large convection clouds fed by cold air that has descended from more northerly latitudes. This clash of air masses with very different conditions has contributed to intense showers, accompanied by electrical activity, hail, and sleet (for example, in Arbúcies). By mid-afternoon on Saturday, we had already accumulated up to 35 l/m 2 in Sant Llorenç Savall and between 15 and 30 l/m 2 around the Montseny massif.
