Requires NOAA (through the Under Secretary) to build AI-ready weather, water, and space‑weather datasets and tools, test and support AI-based forecasting models (including a global AI weather model), and develop a fire-environment AI modeling program. It directs NOAA to inventory and assist major non‑Federal AI weather models, form new public-private and academic partnerships, develop workforce capabilities, adopt best practices to limit environmental impacts of AI, and make data and code publicly available under open licenses except where national security, IP, or contract restrictions apply.

Aimed at improving short-term to seasonal forecasts, forecast confidence, and impact-based decision support, the bill emphasizes competitive contracting, cooperative agreements, technical assistance to state and local forecast offices and communities, and reporting to Congress; it does not itself appropriate funding or change other laws governing national security or proprietary information.
