I am honored to be considered for the AMS Executive Council representing the Government Sector. Throughout my career in government service, I have seen firsthand the pressures that federal budget uncertainties, evolving policy landscapes, and operational constraints place on environmental professionals. These challenges underscore how essential collaboration, standardization, and professional community truly are to sustaining the quality and integrity of our work.

My service on the American Nuclear Society Standards Board and the Environmental and Siting Consensus Committee has given me the unique opportunity to work alongside regulators, national laboratories, public and private industry partners, and fellow scientists committed to improving environmental and energy-related standards. My work supporting ANSI/ANS-3.11 has illustrated how thoughtful meteorological guidance directly improves decision-making and safeguards communities. These experiences have reinforced my belief that standards development is a powerful mechanism for advancing both scientific rigor and cross-sector collaboration.

As a Certified Consulting Meteorologist and an associate member of the Association of Certified Meteorologists, I have also had the privilege of serving twice on the Board of Certified Consulting Meteorologists. In that role, I heard many stories from professionals across the weather, water, and climate enterprise who view certification not only as a mark of excellence, but as a source of stability during times of employment uncertainty. These conversations highlighted the importance of supporting a strong, resilient professional community, one where credentials, mentorship, and peer engagement help individuals navigate change.

If elected to the Executive Council, I will work to elevate the visibility of opportunities for government-sector professionals to collaborate with colleagues across industry, academia, and national laboratories; strengthen AMS’s role in supporting and advancing standards that underpin environmental operations and energy-sector decision-making; and promote certifications, professional development, and community support as vital tools for resilience in an era of uncertainty. I am committed to fostering a more connected and empowered AMS community so that all members, across every sector, can continue to make meaningful contributions to society.

I would be grateful for your support.

The availability of new AI tools, unprecedented budget challenges, and extreme weather events threaten our community's livelihoods, resource availability, and safety. We are feeling the pressure from these challenges and changes in our personal and professional lives. To navigate these rough waters, our AMS community must rise together to harness new technologies, support each other as the roles of private, government, academic sectors shift, and boldly move forward, focusing on the opportunities and actions that ensure science, our members, and society not only survive, but thrive. 

As a federal and academic employee for 30 years, I’ve experienced life-changing technological advancements, swings in funding, and life-threatening disasters, like the devastating May 31, 2013, El Reno tornado, which killed 8 people, including scientists in our field. I’ve also experienced the power of our combined efforts as we’ve weathered these storms. 

If elected to the AMS Council, I will focus on three things: 1) prioritize education opportunities and career guidance to ensure our continued relevance, 2) identify new funding resources to strengthen our mission, and 3) leverage our diverse expertise to empower community resilience to extreme weather threats.  

The success of our Society, the trusted source for weather, water, and climate science information that serves society, depends on us. My commitment is to work with you to identify and walk the paths forward to ensure AMS leadership in science and service to society thrives.


Dr. Pam Heinselman works at the NOAA National Severe Storms Laboratory (NSSL), where she serves as the Deputy Director for Science, leading and championing NSSL’s collaborative science portfolio. She is also an AMS Fellow (2024) and co-chair for the 2025 AMS Annual Meeting Overall Planning Committee. Her love for the NOAA and AMS missions, meteorology, and for people drives her dedication to advancing science in service to society. Throughout her career, she has a rich history of collecting weather observations, developing new forecast tools, and conducting user-focused research to revolutionize forecast capabilities.

Heinselman’s career spans academic and government sectors, working first as a Research Scientist at the University of Oklahoma, Cooperative Institute for Mesoscale Meteorological Studies and then at NSSL, where she has served as Warn-on-Forecast Program Lead and Forecast Research and Development Division Chief. She also enjoys working with students as an Affiliate Associate Professor of the University of Oklahoma’s School of Meteorology. She is a recipient of the DOC Gold Medal for Science and Engineering (2024) and the National Weather Association’s Dr. T. Theodore Fujita Research Achievement Award (2021). Currently, she is a committee member at large of the AMS Publications Commission and member of the AMS Annual Meeting Oversight Committee. Driven by a childhood fear of thunderstorms and a commitment to providing forecasters with more precise and timely data, she is passionate about severe storms research and the creation of innovative technologies and prediction systems designed to bridge existing forecast information gaps.

As I look at the future of our field, I believe the American Meteorological Society faces a defining moment as artificial intelligence transforms weather and climate science. To successfully navigate this transition, we must confront several pressing hurdles across our enterprise:

  • The Demand for Decision Support: We are seeing a growing need for actionable decision support tools rather than raw data alone, challenging us to translate complex forecasts into practical guidance for communities and leaders.
  • Federal Fragmentation: Progress is slowed by a lack of effective coordination across the Federal Weather enterprise, which makes a unified national strategy difficult to achieve.
  • Observation Gaps: We face a decreasing volume of real-time observations at the scale and resolution needed to truly improve our models.
  • Parameterization Shortcuts: There is a heavy reliance on parameterizations instead of actually calculating the physical parameters, which risks masking underlying physics.
  • AI Training Biases: Our machine learning training datasets frequently take on the inherent biases of the numerical models behind them.
  • Capturing Extreme Events: We urgently need better, higher-resolution modeling to accurately capture extreme events lurking in the tails of forecast distributions.
  • The Human-AI Balance: We must carefully define the evolving partnership between machine-driven speed and human meteorological expertise, ensuring that forecasters remain actively engaged to interpret high-stakes guidance and maintain critical oversight in decision support.

By uniting our community around better data, improved federal collaboration, and rigorous science including effective use of AI, we can ensure our efforts truly protect the public. I look forward to working with AMS to provide meetings and forums for the community to build a strong path forward.
