Former Idaho Territory Governor and former U.S. House of Representative Thomas W. Bennett made an application to the U.S. Army's Signal Service to establish stations at Boise on February 9, 1876.

Both Chief Moore and the Secretary of Agriculture James Wilson supported the establishment of an office in Boise, Idaho which was added to the budget.

Samuel M. Blandford will proceed from Salt Lake City, Utah to Boise, Idaho, to establish and assume charge of a Weather Bureau station at the latter point.”[10] Samuel Blandford was an experienced meteorologist and lawyer who worked at several Weather Bureau offices across the United States mostly in the west.

[1] He began his career with the U.S. Signal Service and worked at the station in New York City during the Great Blizzard of 1888 which he believed eventually gave him tuberculosis.

[11] The office was opened on the third floor of the Sonna Building on the corner of 9th and Main Street on December 1, 1898.

Blandford had two assistants, John C. Dabney and Charles C. Garrett[12] who help take observation and post the forecasts.

[16] A new balloon inflation building was built east of the terminal in October 1954 with a dome on top to hold the signal receiving equipment.

The National Interagency Fire Center (NIFC), was created in 1965 as a way for the U.S. Forest Service, Bureau of Land Management (BLM), and the U.S.
