... 1530Z ... distant thunder heard - 2 Cb cells visible, but atm, we
are in bright sunshine between any activity.

... 1615Z .... thunder has continued: two 'active' cells appear to be
in the vicinity, with rain starting ~1600Z, now temporarily moderate
... thunder not frequent, and as far as I can tell, CC or IC (i.e.
muffled/mid-level stuff).

.... 1710Z ... still rumbling around: not the same storm - probably a
cycle of cells decaying & sparking off in the vicinity - still CC/IC
activity, with no CG seen up to present. Rain has become very patchy -
splots now and then. Cb activity primarily to our east (i.e. Heathrow
side); other side (west) cloud less threatening, with increasingly
brighter skies there.

Martin.
