The CWA is an aviation weather alert for conditions that meet or are on the verge of reaching the requirements for a national in-flight advisory (AIRMET, SIGMET, or SIGMET for convection).

The main purpose of the CWA is to help flight crews predict and steer clear of bad aviation weather while in the air and at the airport. IFR denotes either a visibility of less than three miles or a ceiling of less than 1,000 feet AGL. A subcategory of IFR is called low IFR (LIFR). VFR refers to conditions with a ceiling higher than 3,000 feet AGL and a visibility of at least five miles. The SIGMET, the Convective SIGMET, the AIRMET (text or graphical output), and the Center Weather Advisory (CWA) are the four forms of inflight aviation weather warnings. The FAA terminal Doppler weather radar (TDWR), placed at various significant airports across the nation, also helps the ATC with severe aviation weather alerts and advisories. Pilots can avoid dangers to approaching and departing aircraft by being aware of wind shear, gust fronts, and severe precipitation thanks to terminal radar.

The concept of abductive reasoning, also known as abduction, abductive inference, or retroduction, was developed by American philosopher Charles Sanders Peirce in the latter part of the 19th century. It begins with an observation or group of observations and then looks for the most straightforward and likely inference to draw from them.

In contrast to deductive reasoning, this method produces a reasonable conclusion without really verifying it. Abductive conclusions are characterized as having a lingering element of doubt or ambiguity, which is conveyed in terms like "best available" or "most likely."
