This is my entry for the April contest.
The program gets weather data from 1 or more stations and displays the result in GUI form with up to 8 at once. I enclose 3 sample txt files with Zip locations for it to display. You can easily edit your own files using WordPad. For more see ReadMe.txt file.
The program can cope with metric data but I have made assumptions and yet to see a station use it so more information on units would be appreciated so I can update the program to convert imperial to metric and visa versa.
