I suspect that the cloud is quite complex & morning IR pix show quite
a fairly cold top;

.... "quite a fairly cold top"!!! That's my old 'public service forecast'
background coming out - sorry.

Looking at the 00Z ascents, temperature of cloud top somewhere
around -7, a bit lower than yesterday I think. The cloud outside now
(1040Z) has more 'structure' than this time yesterday, and the
visibility is better - around 4500m. OAT still well below zero though,
as is the grass min. thermo. reading (-1.2).

Martin.
