NOAA Storm Prediction Center The Storm Prediction Center is a United States federal meteorological center that issues convective outlooks, watches, and guidance for severe thunderstorms and tornadoes across the United States and adjacent waters. It operates within the National Weather Service and the National Oceanic and Atmospheric Administration system, collaborating with regional weather forecast offices, emergency managers, and academic partners to reduce risk from severe convective storms. The center's work intersects with historical events, operational forecasting advances, and flagship research programs that shape modern severe-weather warning practices.

History

The center traces its lineage to research and operational efforts stemming from the United States Weather Bureau era, evolving through reorganizations in the National Oceanic and Atmospheric Administration and the National Weather Service. Early milestones include the creation of centralized convective warning coordination during the mid-20th century and subsequent relocations and renamings that paralleled initiatives such as the Project NIMROD research period and the development of the National Severe Storms Laboratory. The center moved to its current hub in Norman, Oklahoma near institutions like the University of Oklahoma and the Severe Storms Research Center, benefitting from proximity to the National Weather Center complex. Over decades, the center adapted to lessons from major outbreaks tied to events like the Super Outbreak of 1974, the Joplin tornado (2011), and other high-impact episodes that catalyzed changes in policy, warning criteria, and collaboration with entities such as the Federal Emergency Management Agency and the American Red Cross.

Mission and Responsibilities

The center's mission aligns with mandates from National Oceanic and Atmospheric Administration leadership, focusing on anticipating and communicating severe-convective hazards to protect life and property. Responsibilities include issuing categorical convective outlooks that inform State Emergency Management operations, coordinating with regional Weather Forecast Office networks, and providing decision-support services for events like large public gatherings and emergency evacuations. The center supports interagency coordination with partners such as the Department of Homeland Security, the Federal Aviation Administration, and the United States Air Force when severe convection threatens aviation, critical infrastructure, or national security interests. It also supplies guidance used by broadcasters, private sector meteorological services, and academic research groups across institutions like the Massachusetts Institute of Technology and the National Center for Atmospheric Research.

Forecasting Products and Services

Core products include convective outlooks, tornado watches, severe thunderstorm watches, mesoscale discussions, and experimental probabilistic products that inform Emergency Management and media partners. The center issues day-ahead categorical risk assessments that feed into operational planning at Weather Forecast Office locations and are used by broadcasters including The Weather Channel and national media outlets. It operates collaborative warning operations during high-impact events, providing mesoanalysis tools and coordination with the Radar Operations Center, the National Centers for Environmental Prediction, and regional River Forecast Centers when convective storms produce flooding. The center leverages model guidance from the Global Forecast System, the North American Mesoscale Model, and ensembles like the GEFS to craft outlooks, while also producing probabilistic hazard forecasts used by utilities, transportation agencies including the Federal Highway Administration, and the National Aeronautics and Space Administration for research campaigns.

Research and Technology Development

Research partnerships with the National Severe Storms Laboratory, the University of Oklahoma, the Cooperative Institute for Mesoscale Meteorological Studies, and multiple universities drive advances in convection science, Doppler radar interpretation, and storm-scale numerical prediction. The center participates in field programs such as VORTEX projects and collaborative observing campaigns with the National Center for Atmospheric Research and international partners like the World Meteorological Organization. Technology development includes improvements in mesoscale analysis tools, probabilistic hazard mapping, and integrating data from systems such as NEXRAD, Doppler radar, and emerging remote sensing platforms deployed by NASA. The center also evaluates performance metrics, verification methodologies, and human factors research in partnership with institutions including Carnegie Mellon University and Texas Tech University to refine warning decision processes.

Organizational Structure and Facilities

The center is organized into operational shifts, forecasting teams, and support units that coordinate watch issuance, outlook production, and decision-support services. Located within the National Weather Center in Norman, Oklahoma, it sits alongside the National Severe Storms Laboratory, regional Weather Forecast Office staff, academic research groups, and private-sector tenants. Governance aligns with National Oceanic and Atmospheric Administration and National Weather Service policy, while operational leadership engages with regional directors and program offices such as the Office of Weather and Air Quality. Facilities include advanced operations suites, collaborative conference spaces used with partners like the University of Oklahoma School of Meteorology, and data centers that ingest inputs from national assets including the National Centers for Environmental Prediction and the Radar Operations Center.

Training, Outreach, and Partnerships

Training programs include expert continuing education for forecasters, collaboration with the Federal Emergency Management Agency on emergency response exercises, and joint workshops with academic partners such as Penn State University and Colorado State University. Outreach extends to media training for broadcasters, public preparedness initiatives with organizations like the American Red Cross and state-level emergency management agencies, and engagement with international partners through forums hosted by the World Meteorological Organization. The center also supports student internships, cooperative research agreements with universities, and professional development tied to organizations such as the American Meteorological Society and the National Association of State Emergency Medical Services Directors.
