<P0-S0> The National Weather Service Boise, Idaho is a weather forecast office responsible for weather forecasts, warnings and local statements as well as aviation weather forecasts and fire weather forecasts for 3 counties in Southeast Oregon and 14 counties in Southwest and South central Idaho. <P0-S1>  The U.S. Weather Bureau established an office in the Sonna Building on December 1, 1898. <P0-S2>  Since then, the U.S Weather Bureau office, now known as the National Weather Service forecast office gained forecast responsibility of Southern Idaho on June 22, 1970 which was expanded to the entire state of Idaho in 1973. <P0-S3>  After modernization in 1993, the forecast responsibility was changed to Southeast Oregon and Southwest Idaho. <P0-S4>  The current office in Boise maintains a WSR-88D (NEXRAD) radar system, 8 Automated airport weather station (ASOS) systems and Advanced Weather Interactive Processing System (AWIPS) that greatly improve forecasting in the region. <P0-S5>  Continuous weather observations have been maintained for the city of Boise since February 1, 1964 about 5 months after the U.S. Army established Fort Boise. <P0-S6>  The post surgeon for the U.S. Army took observations until July 1, 1877 when the U.S. Signal Service, established an office downtown. <P0-S7>  The Signal Office was discontinued on July 1, 1890. <SEP> <P1-S0> National Weather Service – Topeka, Kansas (Abbreviation TOP) is a local National Weather Service forecast office based in Topeka, the state capital of Kansas. <P1-S1>  Its offices are located near Philip Billard Municipal Airport. <P1-S2>  It provides weather and emergency information to 23 counties in north-central, northeast, and east-central Kansas. <P1-S3>  Communities that rely on the Topeka Weather Office for forecasts and severe storm warnings include Abilene, Clay Center, Concordia, Council Grove, Emporia, Hiawatha, Junction City, Lawrence, Manhattan, Marysville, Ottawa, and Topeka. <SEP> <P2-S0> Council Grove is a city and county seat in Morris County, Kansas, United States. <P2-S1>  This city is fifty-five miles southwest of Topeka. <P2-S2>  It was named after an agreement between European Americans and the Osage Nation about allowing settlers' wagon trains to pass through the area and proceed to the West. <P2-S3>  Pioneers gathered at a grove of trees so that wagons could band together for their trip west. <P2-S4>  As of the 2010 census, the city population was 2,182. <SEP> <P3-S0> Fort Osage (also known as Fort Clark or Fort Sibley) was an early 19th-century factory trading post system ran by the United States, being located in present-day Sibley, Missouri. <P3-S1>  The Treaty of Fort Clark was signed with certain members of the Osage Nation in 1808 calling for the creation of Fort Osage. <P3-S2>  It was one of three forts established by the U.S. Army to establish control over the newly acquired Louisiana Purchase territories. <P3-S3>  Fort Madison in SE Iowa was built to control trade and pacify Native Americans in the Upper Mississippi River region. <P3-S4>  Fort Belle Fontaine near St. Louis controlled the mouth of the Missouri. <P3-S5>  The fort ceased operations in the 1820s as the Osage in subsequent treaties ceded the rest of their land in Missouri. <P3-S6>  A replica of the fort was rebuilt on the site between 1948 and 1961. <P3-S7>  The Fort Osage school district (including Fort Osage High School), which serves northeast Independence and the surrounding area, was named after it.
