Hmmm....
For entering a new city into this weather forecast application, you need an 8-character city code. (The city code is 4 capital letters followed by 4 numbers. Just grab those codes matching this pattern from inside the URL's when viewing weather forecasts at
National and Local Weather Forecast, Radar, Map and Report or
The Weather Network on your desktop PC, and save the 8 character code into the BBWeather software, and viola.)
The search button, Google and Mark Rejhon are all your friends!
