I'm using a product called WeatherDisplay ($70), linked to my  Davis Vantage Pro weatherstation, to broadcast my weather conditions to one of my websites at http://www.waltersfalls.ca/.  Right now their are some issues with the radar and weather forecast pulled in from Environment Canada, due to a format change on their part.  However, the current weather conditions are accurate and up to date.

This software also broadcasts my weather conditions to WeatherUnderground, as well as to a few regional weather networks.  I really like the reports it puts out, as I can go on the website anytime and go to Almanac/Station Monthly Reports and look up exactly what the average is for the month, the total liquid precip, etc.  It'll even calculate CHUs, although I don't have that uploading to the website yet.
