The primary responsibility of the Analysis and Forecast Branch (AFB) is to verify and validate new tools and innovations designed to help forecasters assimilate, analyze and exploit environmental data in order to improve forecasts and warning services. The Branch validates tools created both internally and externally within the weather enterprise, academia, or other federal agencies. The Branch collects the field's needs on the tools and develops requirements that will help improve the tools. The Branch recommends which tools will be targeted for investment and implemented to field offices for operational use. The Branch works to find methodologies or techniques to improve weather analyses and forecasts, and reports findings to senior leaders. The Branch also works closely with the Modeling, Testbeds and Research to Operations (R2O) Teams of the Office of Science and Technology Integration (STI) as well as NCEP’s Environmental Modeling Center (EMC) to implement tools and techniques for operational use.

In particular, WPC provides guidance on the development and track of winter storms. The service programs include products and services provided to the general public; and to those responsible for local and county public safety; and to the lead Federal agencies for handling nuclear hazard events. The Public and Winter Weather Services coordinates with the World Meteorological Organization (WMO) to lead the advancement of public weather services by and for other countries within the international community. The Public and Winter Weather Services also works with Federal transportation agencies on weather issues related to surface transportation; with Federal and private entities to support the Health (extreme heat or cold), and Ultra-Violet Index program. These service programs work with the Office of the Chief Learning Officer to ensure public and winter forecast training needs are identified and met. The service programs lead and/or participate on service-oriented Integrated Working Teams to prioritize public and winter weather-related service development, to approve new or improved product designs, and to ensure the delivery of public, winter and environmental hazard event products to users. The Public and Winter Weather Services establishes partnerships internally and externally to collect and validate public weather, winter weather and environmental hazard event service and mission needs, solicits feedback on its products and services, and evaluates whether these meet the needs.
