Definition
A weather forecast made by an automated system that projects conditions forward in time using only the data already received, without incorporating any additional observations or human input after the forecast is generated. It is typically a short-term prediction produced by an Automated Weather Observing System (AWOS) or similar automated station, extrapolating current trends to estimate near-future conditions.
Plain English
A short-term weather guess made by an automatic weather station based only on what it has already measured. Once it makes the prediction, it does not get updated with new information until the next prediction cycle.
Context Anchor
Seen in discussions of aircraft displays, flight guidance, automation, and warning systems that predict where the aircraft is going or what it will do next.
Derivation
The name describes exactly what it is: a prediction made with no further input after the data cutoff. Each word carries its plain meaning, but together they signal a specific kind of forecast — one that is frozen at the moment it is issued.
Why Pilots Care
Helps pilots judge how current or potentially stale a forecast may be when conditions are changing.
Grounding Statement
Picture freezing the pilot’s hands and the aircraft’s current settings, then asking: where will the airplane go if it simply continues from here?
Intuition Check
Do not read this as a promise of what the aircraft will do. It means “what is predicted if no one changes anything from now on.”
Example Sentence 1
The AWOS broadcast included a no-further-input prediction suggesting visibility would hold at three miles for the next hour.
Example Sentence 2
We compared the no-further-input prediction against real-time METARs before takeoff.
