If you know the ICAO not the IATA code you can get the weahter for any
city.
Airnav.com I know will look up the ICAO codes for quite a few airports.
The first letter designates the country or area. K is the prefix for
most USA airports, P for Hawaii, E for Europe
ICAO and IATA codes are NOT always the same
here is an example for Hamburg Germany ICAO is EDDF while IATA is HAM

Phoenix Arizona USA ICAO KPHX and IATA PHX

I have these bookmarked and it's a quick way to get weather info
last week, I took a trip and used the
http://weather.noaa.gov/weather/current/KSTL.html to get info on where I
was going
the 4 letter location code must be in all CAPS as this is hosted o na
unix machine and unix is very CASE sensitive.
