[Xastir] How to get CWOP weather on APRS network

[Steven Morrison]

I currently have an APRS i-gate xastir running on a raspberry Pi, and a 
weather station sending weather reports to APRS-IS network using TCP-IP 
running on another Raspberry Pi running WeeWx.  I want  get the  weather 
reports from my weather station transmitted over RF network.

I can configure the WeeWx program to generate a report and send it to 
the xastir Pi, but how can i receive that report and transmit it in 
xastir? Another approach would be to read the new weather entries sent 
to APRS-IS for my callsign and transmit them from that report.

I don't know how to attack this problem, so suggestions are welcome.
