WeatherManX 1.0, a new application for Mac OS X, obtains weather conditions and forecasts from the National Weather Service.
Packing AppleScript support, WeatherMan can serve up current conditions (temperature, wind chill, heat index, wind speed, wind direction, barometric pressure, dew point, relative humidity, sky conditions, visibility), and NexRad radar images. The current temperature is displayed in the Dock, and a floating window is optional. Weather watches and warnings are planned for an upcoming version.
You can download WeathermanX (a 1.8M file) from the author’s home page.
