Great Falls National Weather Service is a regional forecasting office responsible for weather warnings, forecasts, and hydrologic services for a multi-county area in central and north-central Montana. The office issues watches, warnings, and advisories that affect aviation operations, agriculture, emergency management, and public safety for communities including Great Falls, Montana, Helena, Montana, and Fort Benton. Staff coordinate with federal, state, and local partners to monitor severe convection, winter storms, flood events, and fire weather conditions across a diverse terrain that includes the Rocky Mountains, Missouri River, and high plains near Glasgow, Montana.

History

The office traces its lineage to early 20th-century meteorological stations in Montana, evolving through organizational changes in the United States Weather Bureau and later the National Oceanic and Atmospheric Administration and National Weather Service. Early instrumental observations were linked to river navigation at Fort Benton, Montana and agricultural reporting networks tied to Montana State University. Postwar expansion of radar technology paralleled national programs such as the deployment of the WSR-57 and later the WSR-88D radar network, reflecting upgrades also seen at regional centers like Billings, Montana and Missoula, Montana. The office has responded to infrastructural modernization efforts associated with initiatives from the Federal Emergency Management Agency and interagency exercises with the Department of the Interior and Bureau of Land Management.

Jurisdiction and Forecast Area

The forecast area encompasses counties that include portions of Cascade County, Montana, Teton County, Montana, Chouteau County, Montana, and adjacent jurisdictions along the Missouri drainage. The office coordinates hydrologic forecasting for tributaries of the Missouri River and issues river stage products that complement work by the United States Geological Survey. Airspace coordination involves partners at Great Falls International Airport and Malta Municipal Airport, and warnings are distributed to tribal nations including the Blackfeet Nation and Fort Belknap Indian Community. Mutual aid and communication channels link this office with neighboring forecast offices in Billings, Montana, Glasgow, Montana, and Missoula, Montana.

Operations and Services

Core services include the issuance of severe thunderstorm warnings, tornado warnings, blizzard warnings, winter storm warnings, flood watches, and fire weather forecasts in alignment with national directives from the National Weather Service. The office maintains aviation weather products such as Terminal Aerodrome Forecasts for facilities like Great Falls International Airport and provides marine-adjacent hydrology advisories for river navigation authorities. Data dissemination occurs via collaborations with national platforms including the National Oceanic and Atmospheric Administration web services, emergency alerting through the Federal Communications Commission-mandated systems, and coordination with the National Center for Atmospheric Research for mesoscale model support.

Office Structure and Staffing

Staffing includes meteorologists, hydrologists, electronic technicians, and administrative personnel employed under the National Weather Service framework within the National Oceanic and Atmospheric Administration. Positions range from entry-level forecasters trained through the National Weather Service Career Development Program to senior warning coordination meteorologists who liaise with agencies such as the Federal Emergency Management Agency and state emergency management offices. Technicians maintain instrumentation in concert with the National Data Buoy Center and other technical units, while cooperative observer networks draw volunteers coordinated with Montana Mesonet partners and agricultural extension services at Montana State University.

Weather Radars and Instrumentation

The office operates and monitors a Doppler radar drawn from the Weather Surveillance Radar, 1988 Doppler family, integrated into the national Next-Generation Radar architecture that feeds reflectivity, velocity, and dual-polarization products to regional centers like the National Centers for Environmental Prediction. Surface observations are augmented by Automated Surface Observing Systems at airports such as Great Falls International Airport and by cooperative observer stations in rural communities. Upper-air data support comes from regional radiosonde launches coordinated with national launch schedules used by the National Weather Service and National Oceanic and Atmospheric Administration for numerical weather prediction.

Significant Events and Responses

The office has issued critical forecasts and warnings during major events such as widespread winter blizzards affecting interstate corridors like Interstate 15 (Montana) and river flood episodes along the Missouri River that required coordination with the United States Army Corps of Engineers. Severe convective outbreaks producing large hail and damaging winds prompted multi-agency responses involving Montana Department of Transportation and local emergency managers. Fire weather forecasts and red flag warnings have supported wildfire response efforts that engaged the U.S. Forest Service, Bureau of Land Management, and incident command teams during complex incidents in nearby national forests.

Community Outreach and Partnerships

Public outreach includes weather preparedness talks, spotter training for the Skywarn program, and coordination with media partners such as regional television stations in Great Falls, Montana and radio emergency networks. The office partners with academic institutions including University of Montana and Montana State University for research, student internships, and outreach to agricultural extension networks. Collaborative drills and mutual aid agreements involve state agencies such as the Montana Department of Emergency Services and tribal emergency authorities to improve resilience to floods, winter hazards, and wildfire threats.
