After the passage of the trough, foehn winds entered the southern Alpine valleys and the Po Valley where visibility improved and relative humidity dropped to 20% (e.g. in Locarno) with temperatures around 20 °C.
Somewhere close to Verona the north-westerly foehn winds encountered the north-easterly Bora winds (60 km/h in Trieste), which had started to invade the north-eastern parts of Italy (Friuli Venezia-Giulia and Veneto regions).
As can be seen in the animation, the confluence of the two wind systems triggered a line of cumulus clouds which may have caused some weak rain showers in the area of Verona.
