If you are talking about the Skywarn system, I found this file describing how to add it to a node.
I have never tried it and I would be interested in how you make out. https://hamvoip.org/howto/AutoSky_howto.pdf
If you have a HotSpotRadio.com node, they have reported that the radio HAT has a problem with PL tones below 100.0. So be sure not to use a PL below 100.0
how can I add the weather to my node
