... in fact, I must have been hearing very distant thunder for at
least 10 mins, but it's only now that I'm sure. Sky turning darker
from south - where I judge the activity to be coming from.
Medium-level cloud, but decidedly 'lumpy' (Castellatus). Thunder
frequency roughly 3 per min. currently, suggest mid-level CC/IC
activity.


.... (0758Z): now slight rain, thunder louder - no more updates as I'm
shutting down. Looks quite threatening from the south.
