Other observation today:
16:30z (13:30art) Overcast, no rain, no thunder.

17:50z Things are getting funky. Winds with humid and warm air from north, thunderstorms closing up.


17:53z Rain, Thunderstorm

19:10z Storm is over, no wind

In this last shot there is also an interesting 11:11 'up-sweeper to down-sweeper' ratio.
(How) Does weather influence the propagation of the sweepers?
