In case anyone is interested; I put together a script that lets me notify myself and up to three people via phone of inclement weather at any Personal Weather Station, using Wunderground’s API’s. You’ll need a Wunderground developer key, but they’re free for limited use.
I’ve been using it a few months now; the only challenge I still have with it is that seemingly the cron job for resetting weather state twice a day only fires once, and occasionally when the SmartThings notification queue gets backed up I’ll get text messages at 2 or 3 in the morning.
Lots more could be done with it, I’ve kept it pretty simple so far as I’m still learning the scripting environment. It’s all up here on GITHub, not sure if I’ve used GIT the right way or not, I’m used to Visual Studio and TFS. Feel free to suggest changes or point out bone-headed mistakes.
