Support Alerts from api.weather.gov

[dpaulat]

I live in Oklahoma and as everyone knows weather is a thing here, I love the program so far, as I was using this for the first time the other day I was curious why I did not see watches in the list of alerts, and it looks like CoD doesn't do watches only warnings so I started looking to see if I could configure a different source and I figured why not go straight to the source, NWS, I found they offer an API, if you want to call it that, where the data is listed in JSON, but as you mentioned in this post, SupercellWx doesn't read it.

So my suggestion as you move forward with modding the alert providers is to include a parser for the JSON data format the NWS posts, and possibly allow us to select watches vs. warnings and/or the "area" for our alerts.

Thank you for an awesome program, it has proven very helpful as I continue to learn more about weather patterns and how to interpret the various data that SupercellWx makes easily available.
