RMK: Low level wind ocnl F5. Considerable directional shear between
surface (ESE) and Ac levels (coming roughly from west or slight south of

'main' layer high, well-broken; 2 oktas very thin Cirrus above. A fine,
breezy morning.

RMK: Ac Cast base somewhere around 7000/8000ft, with 2 oktas Ac around
3000ft above this. Quite vigorous vertical development, though overall
amount of medium cloud has decreased (from max 5 oktas) during past
hour. Also thin Cirrus, with the sky becoming milkier.

CAST, 1 okta AC (patchy/thin) and 2 oktas Cirrus. (CAVOK of course)=

Hi,

The floccus duly provided all the clues and my brother confirmed that it
thundered back at base (Newbury - circa 12pm) Also where I was birdwatching
at Farmoor, just north of Oxford several claps and a few single cells in
general area at same time.

Muggy cheers

Tony

Hi,

The floccus duly provided all the clues and my brother confirmed that
it
thundered back at base (Newbury - circa 12pm) Also where I was
birdwatching
at Farmoor, just north of Oxford several claps and a few single cells
in
general area at same time.

.... interesting that thunder was actually recorded. Nothing here apart
from the few spots of rain from high-base cloud that managed to make it
to the surface. The cloud certainly looked 'angry' enough for a short
time.

Martin.
