I notice on the 10 am radar on both IR and vis a very well defined but
completely isolated clump of thick cloud over the Midlands. I wondered
at first if there had been a fire. Not associated with any rain.

That was mentioned on the morning forecasts Dave,tho you were probably not
up at that time....

The patch of cloud to which you refer, Dave, is at about 6000ft-7000ft, and
can be traced back to yesterday's convective activity just east the Welsh
border. The convection was capped at that level, and produced a saturated
area which would probably have been maintained by an absence of dynamic
descent in that layer plus internal convective overturning as a result of
cloud top cooling.

Thanks Bernard, for the explaination. It now seems to be diffusing
outwards and has in fact caused high level cloud here. A very
interesting image still, as the central area is still surrounded by its
own clear border.
....... and Ron, you are right ;-)

A fascinating radar sequence. 3 hrs ago it was surrounded by cumulus .
Now the patch has presumably gone, as the area has been taken over by
cum. How interesting, Bernard, that it comes out at 6-7000 ft- to me
it could have been ground mist

Didn't mean radar obviously! Meant vis. satellite

Still interesting in that you usually see things changing in a linear
direction but this is expanding radially, like a slow motion explosion,
gradually engulfing most of England.

Very strange looking.
Reminds me of those pictures you see of penicillin where there is
a clear area between the penicillin mould and the bacteria.

Yes just like that. It would be nice to develop a local immunity to cloud!

I went out at 10am this morning, and was quite worried when I saw Ac
with fall streaks. I was thinking there was a possibility of showers
this afternoon. All that happen was Cu built up from around 11am and
spread out into Sc by the afternoon.
