Hi All

One of our fellow members (WILCO737) posted this in a previous thread:-

EGLL 201050Z 28004KT 0250 R27L/0400 R27R/0400 FZFG VV/// M00/M00 Q1041 NOSIG

Could someone explain how to decode this for me as I would love to know  Smile

I know some things like the AIRPORT CODE and that NOSIG referes to no significant change but I would like to know the rest.

Also is there a glossary anywhere with the letters explained? Plus are there any websites where you can get this information real time for airports??

Thank as always

Mark

Phil,

With such a high qnh, light winds, and close dew point, dont see that fog moving on for some time.

That is a good little link, thank you.

I just posted on this yesterday in my blog. I know there have already been a couple pages posted on how to decode, but if you don't want to bother decoding it yourself, you can go to WeatherUnderground. They give you at least a partially decoded version. (Click on the aviation link once you get to the weather page you want.)
