A series of scripts to ingest and store NWS watch/warning/advisory products via Unidata’s LDM. Will eventually expand to forecast and METAR processing as well; baby steps for now, though.
All responsibilities for outputting the results of parsing out products from LDM will be placed on the Alerter going forward. Thus, a lot of what's new in 2.0 has been more code deletion than anything else. Version 2.0, instead of handling the entire lifecycle of a request from receiving it from LDM to sending it out over Twitter, will just dump everything in a pub-sub-aware database (currently RethinkDB) and let other worker processes figure it out. This should improve performance, scalability, and redundancy quite nicely. We store things in JSON; this makes it easy to send the data to virtually anywhere, including directly over a socket into a Web browser. (Wink wink.)

The current version of the LDM ingestor works behind the scenes.
To see its predecessor in action, follow @chswx on Twitter during inclement weather in Charleston, SC to see examples of the bot’s output.

Licensing TBD. Not for use in life or death situations; code is getting better but the level of rigor is below what I would expect for mission-critical things.
Many thanks to @blairblends, @edarc and @chswx\LDMIngest for infrastructure and seeding the initial code for this project.
