0920z SSW F2 70km++ -RESH 5Cb010 08.3/06.9 1010.7
RMK: Cb base occupies less than one okta to the SE, the
rest is medium and upper parts of anvil, including mammatus
and a few isolated turrets. Sky to the W and N mostly
blue with isolated patches of Sc and Ac, and one distant
cu med. Visibility staggering ... detail and colour visible at
Waddesdon hill (28km); Cotswold horizon (65km) quite a
dark blue, so vis in that direction may be close to 100km.
Undoubtedly much less to the S and E but I can't see far
that way. Showers at 0610, 0700-20 (hvy) and 0855
adding 2.1mm to yesterday's total.
