The National Weather Service (NWS) and the Federal Aviation Administration (FAA) share interrelated and complementary missions. The FAA's mission includes safe and efficient aviation operations in our nation's skies, while the NWS's mission includes aviation weather support for the FAA. However, few weather products and services are specifically designed for Traffic Flow Management (TFM). With this in mind, the FAA and the NWS established a joint Traffic Flow Management Weather Requirements Working Group (TRWG) in August 2010 to meet three objectives to: baseline current NWS weather support capability, develop firm requirements for near-term services to Next Generation Air Transportation System (NextGen) Mid-term Operating Capability (MOC), and develop a plan to implement solutions meeting those requirements.

The Implementation Plan outlines near-term actions for the NWS and FAA for weather support to TFM. Much of the first year's actions revolve around development and implementing tools to assess NWS products and services with respect to the new TFM performance measures. Other near-term solutions include the implementation of a winter weather planning forecast and the transition of aviation weather constraint forecasts from the probabilistic category to the deterministic category to better support Traffic Management Initiative decisions.
