I asked Tony from http://www.thorntonweather.com
directly about "what he uses?" Tony is great and does a very good job supporting fellow enthusiast. He answered me in the Rocky Mountain Weather Network forums, and I thought I would share. Here is link to his full response:http://rockymountainweather.net/forum/index.php?topic=53.0
Turns out he is using a combination of Interwarn from StormLink Inc. http://www.interwarn.com/iwdesc.html
and the email funtion built into Weather Display.
Interwarn looks great for emailing alerts, and has a bunch more functionality built into the software. I like the fact that I don't have to engineer anything, but install/configure/enjoy. I'm gonna hold off purchasing/installing until the new weather server is up and running. No sense installing 2 times in 1 week.
Thanks for the information ALITTLEweird1. I have looked at CarterLake's site a bunch, but he doesn't have a contact us form script or email alerts/forecast scripts. Carmosaic.com however does, great find.
