This Node.js program will return weather information and optionally send text message alerts to a specified phone number regarding precipitation.
An empty config file can be found in config.default.json. Please copy this to config.json and modify values there to be recognized by the program. Comments are not permitted in the configuration file.

These are available when the app is started normally, e.g. node index.js:
- weather [tomorrow] - Summary weather
- sunrise [tomorrow] - Sunrise time
- sunset [tomorrow] - Sunset time
- temperature [tomorrow] - Temperature
When app is started with sms as a command line argument (node index.js sms), the SMS commands will be unavailable. Instead, if the chance of precipitation is >= 50%, a single reminder is sent to the phone configured to bring an umbrella. The program exits afterward. The reminder will also report the actual percentage.
Below is syntax you can place into a crontab to send an umbrella reminder at 7 AM each day:
0 7 * * * node path/to/index.js sms
