## Runnning
It takes three arguments, province, city, and types. 
Provinces must be in the following list: 

AB: 'Alberta', BC: 'British Columbia', MB: 'Manitoba', NB: 'New Brunswick', NL: 'Newfoundland and Labrador', NS: 'Nova Scotia', NT: 'Northwest Territories', NU: 'Nunavut', ON: 'Ontario', PE: 'Prince Edward Island', QC: 'Québec', SK: 'Saskatchewan', YT: 'Yukon'

It can then be run by invoking the following command: 

```node index.js --province=Ontario --city=Muskoka --types='["sa"]' ```

It will then save three streams to the `/forecasts/` folder. 
- current forecast
- short-term forecast
- long-term forecase

Interval based updates are run using cron. To update on an interval basis, run `index-cron` with the `--interval` flag set to one of `secondly, minutely, hourly, or daily`:

```node index.js --province=Ontario --city=Muskoka --interval=hourly```
