The Weather Star I, like its two subsequent successors, lacked the ability to generate graphics and was only capable of displaying white text on various backgrounds: purple for the "Latest Observations" (which displayed current weather conditions for the nearest reporting station and others within a radius of the headend location) and "Weather Information" (which displayed random data, usually weather-related trivia, past weather events in the area, or information on upcoming programming) pages, grey for the "36 Hour Forecast" page (a descriptive forecast using the National Weather Service's zone forecast products), brown for scrolling weather advisories, and red for scrolling weather warnings. Until the release of the Weather Star III, The Weather Channel used a single one-minute local forecast sequence featuring each of the three above-mentioned forecast screens. As with all future WeatherStar models, the Weather Star I could key its text over TWC's national video feed, most often to display the current conditions at the bottom of the screen.
