YAMQ - Yet Another METAR Question
All,
Looking at the METAR for Leeming, I saw the following: EGXE 291150Z 17003KT 6000 HZ BKN013 19/16 Q1020 GRN BECMG 8000 BKN018 WHT Thanks |
They are military terms for overall conditions. They use colours to describe the weather. Can't remember exactly which colour means what, but I'm sure someone else will be able to fill in the blanks.

The exact meaning of those colors are usually listed in the AIP. And I think they're in the Jeppesen preamble section too. They're a combination of cloud base and visibility and as far as I remember, the darker the color the harder the approach.
Edited: See Military Colour Codes for METARs by Irv Lee |

All makes sense now. Thanks to you all for the prompt replies

... they are simple terms, for our military friends to understand ...

I asked the met office the same question lst year and received a very helpful response:
METAR reports from military airfields operated by the RAF, some USAF and others may have a 'colour-code' appended (usually only when ATC is open), which describes the airfield 'fitness': these run from BLU best, through WHT GRN YLO (1 and 2), AMB and RED. The colour is based on the lowest cloud base (usually 3 oktas or more cover, but some use 5 oktas) and the horizontal 'MET' visibility. BLACK is also used, for airfield closed for non-weather reasons. For reference: Black - airfield closed for non-weather reasons Red - cloud < 200ft and/or visibility < 800m Amber - better than Red, but cloud < 300ft and/or visibility < 1600m Yellow - better than Amber, but cloud < 700ft, and/or visibility < 3700m Green - better than Yellow, but cloud < 1500ft, and/or visibility < 5km White - better than Green, but Cloud < 2500ft, and/or visibility < 8km Blue - cloud > 2500ft and visibility > 8km Where 'cloud' is the lowest cloud base designated as SCATTERED or worse I hope this helps and thank you once again for your interest.
