I just find it confusing. They put the original TAF text in, suggesting that what comes next is an interpretation of that bit of text. But what they actually do is take the whole TAF into account. That's why you see things like:
Text: EGNM 061810Z 061904 24006KT 9999 SCT020
Forecast period: 1900 to 2000 UTC 06 July 2008
Where does the 2000 UTC comes from? This bit applies to 0400 UTC, doesn't it? Oh no, later on, you'll find
BECMG 2023 7000 BKN008
So that's where the 2000 UTC comes from.
So... Pretty smart analysis algorithm, lousy presentation of the results.
This is the site I like better:
MET'MAP - ORBIFLY FLIGHT SCHOOL - IFR ET CPL AMERICAIN EN EUROPE - FAA IFR AND CPL IN EUROPE
Mouse over a site to see the METAR and its interpretation. Click on a site to make it your personal center of the universe, then bookmark whatever URL is listed for next time. They don't interpret TAFs though, only METARS. But they do give access to both the short and long term TAFs and I also like the color coding to get a glance of flight conditions. Especially if you combine that with rainfall radar or something like that.
