Trivia

Heinrich W. Brandes made the first weather map in 1815, based on data gathered in 1783. Brandes waited so long because it was the only way he could be certain the information was correct.

How Meteorologists Learned to Map, Predict, and Dramatize Weather by Mark Monmonier

"American weathercasting began on October 14, 1941, on WNBT-TV, an experimental station (later WNBC) serving at best a few thousand viewers in New York City. Hawking Botany Wrinkle-Proof ties, a cartoon character named Woolly Lamb introduced the forecast by singing, "It's hot. It's cold. It's rain. It's fair. It's all mixed up together. But I, as Botany's Woolly Lamb, predict tomorrow's weather." The forecast that followed consisted of a single screen with several lines of text, but no map. As far as I can tell, the distinction of telecasting the first weather map belongs to the British Broadcasting Corporation, which for a brief period in 1936 transmitted to far fewer viewers simple weather charts with isobars and pressure centers as well as temperature, sky conditions, and precipitation for a handful of unnamed cities in the British Isles and the adjacent continent. As Woolly Lamb presaged the weathercaster's role as an entertainer, the BBC experiment demonstrated television's ability to deliver timely weather maps to a mass audience. Although World War II interrupted the new medium's development, postwar prosperity stimulated a new industry in which news programs with weather reports became a standard feature."
