That pleasant smell of rain on warm, dry surfaces
(well, dry until 15 minutes ago) fills the air. Very
narrow but tall CU, are just glaciating into fragile
'chimneys' of CB cal before collapsing, indicating
that there is only just enough moisture to support
these clouds in our area. The sky in the southeast
quadrant is virtually clear of cloud.

A pair of anvils have rapidly sprouted from clusters of
CU congestus clouds to the WSW and E, slowly moving
NW'wards. The sky to the SE and S remains clear.
Distant thunder has been heard from both of these CBs
since 1515Z. Obviously there is still enough moisture!

Thunder has become quite frequent from the CB cell to
the NE and ENE which appears to be expanding and
throwing the anvil shield overhead. The storm is edging
to the WNW.
