Digitized maps of national weather conditions, beginning in 1871. The earliest maps had only basic surface observations, and were created by the U.S. Signal Office as the series War Department Maps. In 1891, publication was transfered to the new Weather Bureau, eventually becoming the Daily Weather Maps series, published weekly. Current maps include surface pressure analysis, maximum and minimum temperature, 24-hour precipitation, and upper air patterns.View listing of recent maps (January 2003 - present; updated quarterly)
