You are correct :

$ wget ftp://tgftp.nws.noaa.gov/data/observations/metar/decoded/KPHX.TXT

will get you a 'decoded' version for phoenix. The data is only updated once
per hour and they recommend pulling it at 10 to 15 minutes after the hour.

The contents of the file are as follows:

$ cat KPHX.TXT
Phoenix, Phoenix Sky Harbor International Airport, AZ, United States (KPHX)

Oct 13, 2002 - 01:56 PM EST / 2002.10.13 1856 UTC
Wind: from the ESE (110 degrees) at 13 MPH (11 KT) gusting to 21 MPH (18 KT):0
Visibility: 9 mile(s):0
Sky conditions: mostly cloudy
Temperature: 93.0 F (33.9 C)
Dew Point: 44.1 F (6.7 C)

The funny looking line at the end of the file is what you get if you download
the 'raw' file.
