Cecil announces each weather segment by saying something like "And now the weather" or "I take you to the weather" (except when he is physically incapable of doing so due to problems like a water failure, but in other dire situations he remembers to announce it even while fleeing from the station). When the weather is over, he sometimes greets his listeners and describes what happened during the weather. Often, what happened was the off-stage resolution to whatever impending crisis the town was facing. In at least one episode that ended with an unresolved crisis, Cecil explicitly comments on his surprise that the crisis was not resolved during the weather.
Apart from those segues, the weather has only been mentioned a few times. When Dana Cardinal is projecting herself from the otherworldly desert into the radio studio, she mentions Cecil's weather announcement and then adds, "The weather is beautiful here."Steve Carlsberg tells a story that involves him chatting with Cecil about the weather, saying, "I remember it was the weather because we had to stand in awkward silence for a bit as we waited for the music to stop playing." In the episodes "The Retirement of Pamela Winchell" and "The University of What It Is" Cecil invokes the weather purposefully to distract other citizens.
Local meteorological events, such as doppelganger-causing sandstorms and noisy sunsets, are covered elsewhere in the broadcast. The shades of the sky are forecast in the Shades of the Sky segment.
