This works in US and Canada now.
 

Email wx@flightaware.com enter your airport identifiers in subject line separated by one space each and within 5 minutes receive TAF and Metar back.

Very cool.

That's an awesome tip -- thanks Jamie!

I just tried it and had results in less than one minute. Nice!

If you have a mac this is much better. Aviation Weather Widget: Home

There is a widget that gives you the TAF's, and Metars at airports around the world. You can program up to 4 airports on quick links. Very useful.

You can also get it on a pc for Yahoo widgets.

Works great, got a reply in like a minute. Will try the Apple widget version as well, kindly provided by Hernando.

That's pretty cool
