Please take a look at some recent METAR reports from Frederick, Maryland,
as acquired from

Can anyone explain the remarks (after AO2)? This comes up occasionally at
weather stations when I am checking a METAR report, and I have never seen
any reference to such notation. I contacted someone at the NOAA and he
wrote it off as a glitch. Perhaps it is, but it occurs fairly often and
makes me wonder -
Thanks in advance -
BS
