Formation of cumulus clouds due to a surface Northeasterly airflow over the Maltese Islands originating from a coldwave in the NorthEast Mediterranean but heavily modified by its sea passage. The weather sounding indicated only limited instability up to an altitude of 2.5km. This weather situation turned the developing cumulus clouds into stratocumulus as can be clearly seen in the top of the photo (stratocumulus). Hence no thunderstorms were observed and these clouds managed to produce only light rain showers over the area. Notice the uneven edge at the very bottom part of the cloud perhaps indicating weak funnels but of course which could not develop into waterspouts due to still stable air aloft despite good wind ingredient for it to occur. Malta was in the frindges of a cold pool of air over the Eastern Mediterranean (third thumbnail).
