Ok, and, to be more precise as in my former posts (oblivious me), I
don't have any other weather related option in use. Like --random-wind
or --turbulence=.
I start with option --timeofday=noon. I am not certain if this matters
but I read something about a 240 minutes 'expiration' or such for the
METAR string. At least screenshot [1] is inside that timeframe.
$ fgfs --disable-real-weather-fetch \
--metar="LOWI 123456Z VRB07G18KT 9999 FEW070 BKN130 18/06 Q1013"

Hmh, I guess the filter is not the issue.
