If anyone is looking to add the daily weather information to their Daily Journal script (see the provided template) here is a handler that uses open source information. The point of providing this is that it does not depend on Yahoo, or Google, o news feeds or other information and, in my experience so far, is pretty reliable.
You can add this into your scripts.
(That’s your homework – you can figure it out if you try a little.)
Requirements:
Location Helper from the Mac App Store (no cost).
JSON Helper for AppleScript also from the Mac App Store (no cost).
API Key From OpenWeather – free for 1,000,000 API calls/month – be careful – don’t go wild with this 
The handler
This uses getWX() to get the data from OpenWeather and format it into a list. You can adjust the API call and JSON parsing to whatever other OpenWeather data you wish.
