If you are going to do this via APRS, you will obviously need a weather 
station, a radio and a TNC of some sort.

Probably the cheapest way would be to pick up an old junker-clunker 
crystal-controlled two-meter rig at a hamfest or swapmeet, crystal it's TX for 
144.39,  and combine it with a Byonics WXtrak.   The WXtrak   ($33 kit or $42 
assembled with case)  is a specialized transmit-only TNC designed solely to 
connect to certain weather stations.  You plug the WX station into the WXtrack 
serial port, and connect the TX audio and PTT at the other end of the device to 
your radio's mic jack or data port.  WXtrack supports a limited variety of 
weather stations. Check the list of supported WX stations before buying one.
