In March 1998, TWC introduced a graphical refresh, featuring heavy use of the Akzidenz-Grotesk typeface and footage of clouds at the core of the new identity. For the first time in the channel's history, there was no slogan or unifying theme. "WeatherScope" was replaced with "Weather Center" on March 10, a program which essentially comprised The Weather Channel's entire 24-hour daily programming schedule at the time in the form of three separate programs ("Weather Center AM", a morning program (5 a.m.-noon) focusing primarily on business, commuter and leisure travel weather; Weather Center PM, an evening program (7 p.m.-5 a.m.) with a focus on forecasts for the day ahead; and an afternoon broadcast (12 p.m.-7 p.m.) simply using the Weather Center title, which focused on ongoing weather conditions). April 1998 saw updates to "The Front" image campaign; one of the new advertisements specifically mentioned the 36-hour text forecasts (which, at the time, were still supplied by the National Weather Service), but heralded new Local Forecast graphics. The machine that produced those graphics, the IRIX-based Weather Star XL, was released to cable providers later that year as the first new mainline STAR unit manufactured in eight years. The catalyst for a top-to-bottom modernization of the local forecast segment, the XL's graphical and technological capabilities were significantly more advanced than the 4000, with an animated, high-quality output consistent with TWC's national graphics and new scalable icons that would be used for eight years on TWC (these icons remain in use by Weather Star XLs still in service and on certain downloadable web widgets).
