Hmmm, cloud amounts with precipitation is something we often comment on in
our duty shift reports.
Far too many FEWs for my liking, almost SAMOS like..

Interesting to see the snow shower though, the 00Z mesoscale did indicate a
few light ones over Gatwick way in the evening.

I remember snow showers like that on Shetland, usually accompanied by a
30kt+ wind.

This happens more often than you might think, Jon. Yesterday at 0900z
there was a snow shower here with 3 OKTAS total cloud and at 1200z a
sleet shower with 2 OKTAs total cloud. The combined effects of
substantial vertical wind shear and the relatively slow rate of fall of
snow flakes can result in the shower cloud producing the snow
disappearing over the horizon before the last of the snow flakes reach
the ground. Mind you, I'm not saying that is what was happening at EGKK
:-)

I'm not ruling it out but I think it's unlikely. I see it as a symptom of
the way the SAMOS system deduces cloud amounts from the data presented to it
by the laser cloud base recorder. There was an interesting example of this
last month at Luton when 8/8 AS/CI was present overhead and yet the METARs
were reporting sky clear.

There's also the small matter of prevailing/directional visibility which is
reported about as often as snow flakes over North Africa :-)

...and then 3 prevailing vis reports come along at once, although I'm not
sure the way Jersey have done it is entirely correct :-
