the weather
 

When I have travel plans (like today) I always check with the airline's web site and various weather services for temprature and conditions, but I have to guess at effected areas.

Is there a website that lists all airports/routes that might be experiencing delays due to weather, so I don't have to back into discovering them.

There should be, anyway.....

Dave,
They attempt to do this on the Weather Channel site at:

I have not checked it for accuracy, but it looks like a pretty ggod layout.
