In my own log book I still note such events as (0.2)w for dew,
(0.2)x for hoar or rime, (0.2)fe for wet fog (where the letter

Thanks Philip (Norman & Steve). For the sake of 30 years continuity I
think
I'll continue to add the 0.2mm to my monthly rainfall total along with
a note
in my log, but not include it as a rain day, as 0.2mm from dew/fog etc
is
a rare 2 or 3 times a year event for me. It seems a pity the OWL
system
can not differentiate between rain and dew etc. In the extreme you
could
have a rain free August with 10 very heavy overnight dews of 0.2mm
and you would record 10 rain days for the month, if I follow Philip
correctly. For all of it's benefits, automation seems far from
perfect
