Hi,
I have a couple of "complaints" about the decoding of the weathergroup(s).
Ref ver 1.55
In the exampel below (from today) we have RA BR. This is translated to
Moderate Rain Moderate Mist.. The prefix "Moderate" is not valid for
Mist. The correct translation is Moderate Rain plus Mist (I found a metar in
version 1.9.5 where BR was reported correct).

BKN005
Ref ver 1.9.5:
In the METAR below (MWCR) the WX group is LGTN which is noncense. Looking at
the clouds, what they ment was probably something like "light thunderstorm -
LGTS" which is also noncense. Note that only weather can have a prefix and
TS is NOT in the category of weather (TS is a descriptor, just like MI, BC,
FZ aso.). E.g. -TS is NOT vaid, but -TSRA is (being Thunderstorm with light
rain).
I think that decoding this report should flag to the user that an invalid
Wx-group was encountered instead of just skipping it.

>From an operational view, the METAR below has the worst error The METAR has
Wx-groups VCTS +SHRA, which is translated to "Currently showers of rain".
The correct translation would be: "Thunderstorm in the vicinity plus showers
of moderate rain".

In the metar below the wx-group -SHRA is translated to "light showers of
rain" showers (being a descriptor) can not be "light", but rain
can..the correct version is "showers of light rain".

I know that these items are not that significant to most people, but I have
seen aeronautical people showing interest (latest Francesco from LIRF), then
it suddently becomes important.
