.... Richard, by the time the front got down here in the south coastal
area, it was even weaker: sporadic, very light rain between 06 & 0730Z
... nothing in gauge (notional 'trace') and surfaces not affected. 11
days with no measureable rain.

I still use Beaufort letters to record my weather, and for that rain,
it should go down as "iro" (the 'o' being a suffix/subscript
lower-case o); it occurs to me that we need a method to distinguish
between light rain which *has* an impact (i.e. produces at least a
dribble of rain in the gauge/wets the surface, even if temporarily),
and the event of this morning when if you hadn't been looking closely,
you might have entered 'nil PPN'.

I always make a note of such events, but as a shorthand, I've started
using 'ox', i.e., lower case x, lower case o, on the same principle
that in clothing measurements, XL is 'extra large', XXL is 'extra,
extra large' etc. So 'xo' is extra slight !?

Anyone else have such a system or a better one? It would also apply to
snow - for example you can have light snow which does impact on the
surface, and the occasion when just a few flakes fall with no impact -
same Beaufort letters, "s(suffix)o".

Hi Martin.
Excellent idea, I will use ox in future, showers overhead (12:21)-
upper cold pool.

.... getting away with it so far (1350Z): some 'perky' Cu med to the
south (over Channel) but a lot of Sc so there's a stable layer to be
broken. However, I see from the IR sequence that there is a line of
markedly colder tops just to the north, so perhaps a shower before too
long.

I wouldn't use x Martin, as that is already used for hoar frost.

.... indeed, we got a light shower (genuine one - just about dampened
the ground), between 1420 & 1440Z; bright sunshine now - but I see
that there were heftier showers to the east - some Sferics too along
the Thames Valley and north Hampshire.

.... agreed it might seem confusing, but written immediately adjacent
to the precipitation type, it doesn't look too bad.
