EGTC 170850Z 22007KT 5000 HZ NLC 19/13 Q1026

Above Metar is from Cranfield, the only translation for NLC I can find is
noctilucent cloud, but at 8:50 in the morning, also reported (as NLC without
the haze) at 9:50 (10:50 BST).

Is it a mistake or does NLC mean something else.

Thanks in advance

Joe in Bedford.

I think it should be NSC for "no significant cloud". I guess NLC
was
meant to mean (if you see what I mean) "no low cloud".

.... whilst we humans can make sense of this ... unfortunately, the
automated VOLMET (and similar) broadcasts will be flummoxed! The
observer at Cranfield may not know that NLC is an abbreviation that is
used in some cases (though not now in main SYNOP coding).

The UK Noctilucent Cloud Observer's website shows no activity yet in
2004, so as others have pointed out, it looks like a mistake. However
it's a good excuse to publicise this URL ;-)

Eiher way it's another duff METAR as all cloud should be reported in UK
METARs unless SKC or CAVOK apply.

Jon, what's the status of sig weather in the last hour, these days,
in
respect of METARs? I still prefer to eyeball SYNOPs rather than
METARs so I don't look at them systematically, but I have the
impression that I don't see many RERAs or RESHs any more.
French METARs (one of which I keep a close eye on)
certainly does not include any RE weather, so, especially in
showery weather, it is impossible to form a complete picture of
the day's weather from the METARs alone.

RERA etc is still used to indicate a change in the intensity of the
precipitation (IIRC i.e. RA to -RA/Nil or +RA to RA) during the period
since the last METAR; but I'd hazard a guess that it's incorrectly
omitted more often than not these days. RESHRA was also introduced in
March.

Jon.
