Met Decode METAR help please
Am revising for my MET exam and have just had a look at the following current METAR for Shawbury:
SHAWBURY EGOS 040950Z 23009KT 9999 FEW018 SCT030 BKN090 16/12 Q1022 BLU NOSIG
Can someone let me know what BLU means? I can't find the abbreviation in the Met Office list. All I could find was BL (Blowing) and U (Upwards -tendency in RVR).
Thanks in advance
Andy

You'll find details in e.g. the front of the VFR Flight Guide, but approximately:
Blue - VFR
White - marginal VFR (usually lowish ceiling)
Green - IFR for IMC rating holders
Amber - IFR for IRs
Red - IFR for Cat II/III ILS use only
Black - airfield closed
