Decaying Cumulus radiatus probably formed due to some local feature such as a sea-breeze front. However, the Maltese Islands were situated in the lower extents of an upper-level trough which might have extended towards Malta for some time. This cloud developed and decayed very quickly because atmospheric conditions at higher levels were hostile for thunderstorm development on the day. However, an increase in wind and drop in temperature were felt. This cloud front was preceded by cumulus congestus as seen on the first thumbnail.
